Description

1 / 38 Docket No. 20086.106.1aLINEAR DRAIN SYSTEMS FOR TILED FLOORS

[0001] BACKGROUND

[0002] Shower areas commonly incorporate linear drain systems to facilitate water removal. Proper operation of such systems requires that the shower floor be sloped toward the drain and that the drain direct collected water to an outlet. However, many existing linear drain systems exhibit shortcomings that negatively affect functionality, appearance, and ease of installation.

[0003] One drawback of conventional linear drains relates to cleaning and maintenance. Access points to the drain outlet and associated plumbing are often poorly positioned or obstructed, making removal of debris difficult. In addition, installation of known linear drain systems can be complex and time-consuming. Proper leveling and alignment are frequently required to ensure adequate drainage, and additional components are often needed, further complicating installation. Another limitation of existing drains is their inability to integrate seamlessly within tiled shower floors. Many linear drains fail to provide true wall-to-wall coverage, resulting in visible gaps that disrupt the visual continuity of the flooring and may promote water pooling or inefficient drainage. Such gaps can also present potential trip hazards. Furthermore, traditional linear drains commonly rely on joining mechanisms that create visible seams or misalignments between drain components. These seams may lead to leakage and detract from the structural and visual integrity of the installation. Difficulty in achieving a flush, watertight interface between the drain body and adjoining members further compounds these issues.

[0004] Another drawback of known linear drain systems relates to installation constraints and aesthetic compromises. Many existing systems require shims, leveling aids, or height adjustments when extending a drain length or joining multiple drain sections, increasing installation time and complexity. In addition, conventional linear drains often fail to provide a flush and watertight interface with adjacent wall panels, resulting in visible gaps, misalignment, or increased risk of leakage. Trim components used with known systems frequently lack features to promote drainage or precise positioning, allowing water to accumulate and tiles to shift over time. Further, access points for maintenance are commonly exposed or require removal of surrounding tile, detracting from the visual continuity of tiled floors and complicating routine cleaning.

[0005] Accordingly, there is a need for an improved linear drain system that enhances access for cleaning and maintenance through a selectively positioned access opening that2 / 38 Docket No. 20086.106.1adoes not interrupt the inlet. There is also a need for a linear drain system capable of providing seamless, wall-to-wall installation that integrates naturally with tiled flooring to achieve a refined appearance. Additionally, the system should facilitate flush, watertight joining of drain components and receiving spaces to ensure structural integrity and a smooth, unobtrusive finish. The present disclosure addresses these needs by providing a linear drain system that overcomes the deficiencies of known designs while offering improved functionality and aesthetic appeal.

[0006] SUMMARY

[0007] Embodiments of the present disclosure provide a linear drain system for installation in a tile floor that improves installation flexibility, structural integration, maintenance accessibility, and aesthetic continuity relative to known drain systems. The linear drain system includes a drain body defining a slotted inlet extending along a length of the drain body, an outlet portion in fluid communication with the inlet, and an access opening in fluid communication with the outlet portion. The drain body further includes a coupling system that permits multiple drain bodies or extension members to be joined and adjusted to length without varying a height of the drain body or requiring shims or other leveling aids, thereby simplifying installation on a subfloor.

[0008] In certain embodiments, the coupling system can be configured to join adjacent drain bodies, extension members, or other components without underlapping the drain body and without raising a height of the drain body relative to the subfloor. The coupling system can operate within receiving spaces formed in the drain body or extension members such that joined components remain flush along a bottom surface of the drain body. This configuration facilitates on site length adjustment and component joining while maintaining a consistent vertical profile of the linear drain system and eliminating the need for shims, spacers, or height compensating elements.

[0009] In certain embodiments, the drain body defines one or more step features configured to directly support adjacent wall panels or other elements. These step features allow the drain body to align flush with and seal against the adjacent elements, facilitating a watertight installation while enhancing a seamless, wall to wall appearance. In certain embodiments, the one or more step features can include a side step extending along at least a portion of a length of the drain body and / or extension member and an end step positioned at or near at least one longitudinal end of the drain body or the extension member. The side step and the end step together define at least in part a stepped perimeter around the drain body. The stepped perimeter is configured to receive and support one or more wall panels3 / 38 Docket No. 20086.106.1aextending parallel and perpendicular relative to the inlet, thereby facilitating installation of the linear drain system at or near walls or wall panels while maintaining a flush and watertight interface. This configuration reduces visible transitions between the linear drain system and surrounding surfaces and improves long term durability in wet floor environments.

[0010] The linear drain system can further include trim members selectively positionable along the inlet and configured to support adjacent tiles. The trim members include locating posts or other projections that cooperate with corresponding openings in the drain body to ensure precise positioning and secure attachment. In addition, the trim members can include weep holes configured to promote drainage and reduce water accumulation adjacent the inlet. Together, these features reinforce tiles, improve drainage performance, and provide a clean, finished transition between the tile floor and the drain inlet.

[0011] According to an embodiment, the linear drain system includes at least two openings that are offset relative to one another. For example, the access opening can be laterally offset from the inlet and is covered by a removable access cover member configured to support a tile portion. This arrangement allows access to the outlet portion and associated plumbing for cleaning and maintenance while maintaining a visually continuous tiled surface. The access cover member can be selectively removed without disrupting surrounding tiles, preserving both the functional integrity of the drain system and the aesthetic continuity of the tile floor.

[0012] According to an embodiment, the linear drain system further includes a coupling system having one or more receiving spaces formed in longitudinal ends of the drain body and one or more joint components configured to engage the receiving spaces. The coupling system provides a spliced or interlocking connection between adjacent drain bodies, extension members, or other wet floor components, allowing the linear drain system to be adjusted to length and joined on site without varying a height of the drain body or requiring shims or other leveling aids, while forming flush and watertight joints.

[0013] In certain embodiments, the linear drain system includes a cover member configured to be tiled over and to cover the access opening while forming at least a portion of the inlet. After installation, a hole can be formed through the tile and the cover member to access the opening, and an access cover member comprising a removable hole cover carrying a portion of tile can help maintain a visually continuous tiled surface.4 / 38 Docket No. 20086.106.1a

[0051] DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

[0052] A better understanding of different embodiments of the disclosure may be had from the following description read with the accompanying drawings in which like reference characters refer to like elements.

[0053] While the disclosure is susceptible to various modifications and alternative constructions, certain illustrative embodiments are in the drawings and are described below. It should be understood, however, there is no intention to limit the disclosure to the specific embodiments disclosed, but on the contrary, the intention covers all modifications, alternative constructions, combinations, and equivalents falling within the spirit and scope of the disclosure.

[0054] It will be understood that unless a term is expressly defined in this application to possess a described meaning, there is no intent to limit the meaning of such term, either expressly or indirectly, beyond its plain or ordinary meaning.

[0055] Embodiments of the present disclosure can advantageously provide linear drain systems that incorporate certain design improvements over known linear drain systems. The linear drain system disclosed herein can define at least two openings that are offset relative to one another. For instance, the linear drain system can include an access opening that can be laterally offset from the main inlet, ensuring an uninterrupted drain inlet along the full length of the floor while simultaneously providing a convenient access point for cleaning and maintenance. This arrangement eliminates the need for unsightly gaps or removable sections in the primary inlet, preserving both form and function. Unlike conventional drains where maintenance access requires disruptive tile removal or creates an uneven flow path, this lateral offset ensures easy accessibility without interfering with the visual or functional continuity of the drain.

[0056] As used herein, an access cover member refers to a removable component configured to cover the access opening and / or support a tile portion while permitting selective access to the outlet portion for cleaning or maintenance. The access cover member can take various forms, including embodiments described herein as an access opening cover, a hole cover, and / or a tray, and can be positioned on or within a cover member of the linear drain system. Unless stated otherwise, references to an access cover member encompass all such configurations.7 / 38 Docket No. 20086.106.1a

[0057] The linear drain systems disclosed herein can be configured to address common installation and maintenance challenges associated with known linear drains. The coupling system permits drain bodies and extension members to be joined and trimmed on site without changing a vertical profile of the drain system, enabling installation directly on a subfloor without shims. Step features formed on the drain body facilitate flush and watertight engagement with adjacent wall panels. Trim members improve tile alignment and drainage, and the laterally offset access opening provides concealed maintenance access while preserving a continuous inlet and tiled appearance. These features cooperate to improve reliability', ease of installation, and long term performance

[0058] Receiving spaces in the longitudinal ends of the linear drain system can be configured to allow seamless integration with adjoining members, ensuring a flush and waterproof connection. This helps to prevent gaps or raised edges that can accumulate debris, enhancing both hygiene and durability while simplifying installation. Unlike conventional systems that require separate sealing components prone to failure, the flush integration ensures a tight, water-resistant junction that improves long-term performance and minimizes maintenance requirements of the linear drain system. Additionally, the drain body and coupling system are configured to allow installers to adjust the drain body to the required length without compromising the integrity of the receiving spaces. This adaptability facilitates efficient installation in various shower layouts while maintaining the system’s seamless and watertight characteristics.

[0059] The linear drain system can extend from wall to wall, achieving a sleek, high-end aesthetic that blends seamlessly with tiled flooring. This continuous design eliminates visual breaks and enhances the perception of spaciousness in the shower area, making it an ideal solution for contemporary architectural preferences. The ability to install the drain directly adjacent to walls or shower entries ensures that the system integrates harmoniously with surrounding materials, providing a visually cohesive and elegant finish. Unlike traditional drains that require visible end caps or gap-filling measures, this wall-to-wall design minimizes interruptions and optimizes water drainage performance. The result is an aesthetically refined, highly functional drainage solution that complements modem bathroom designs.

[0060] It will be appreciated that the linear drain systems of the present disclosure can be installed more easily than conventional linear drains in tile floors, including those with mosaic tiles, square tiles, rectangular tiles, hexagon tiles, large-format tiles, and other types of tile.8 / 38 Docket No. 20086.106.1a

[0061] Figs. 1 through 8C illustrate a linear drain system 100 according to an embodiment. The linear drain system 100 includes a drain body 102 that defines a drain inlet 104 with a slotted configuration extending along a length of the drain body, an outlet portion 106 in fluid communication with the drain inlet 104 for connection to a drain pipe, and an access opening 108 also in fluid communication with the outlet portion 106. The outlet portion 106 is shown extending in a vertical direction but can extending a lateral, horizontal, or other direction in other embodiments. Optionally, the linear drain system 100 can include an adaptor configured to cooperate with the outlet portion 106 and allow the outlet portion 106 to connect to an ABS drain pipe, a PVC drain pipe, metal drain pipe, and / or any other type of drain pipe.

[0062] The linear drain system 100 can define at least two openings that are offset relative to one another. For instance, the access opening 108 can be longitudinally aligned with the outlet portion 106 and laterally offset from both the outlet portion 106 and the drain inlet 104. This advantageously helps provide convenient access for cleaning the outlet portion 106 and the connected drain pipe without interfering with the primary drainage function. The lateral offset between the access opening 108 and the outlet portion 106 further helps ensure that the access opening 108 does not obstruct or disrupt the drain inlet 104 when the linear drain system 100 is installed in a tile floor.

[0063] As a result, the linear drain system 100 can help maintain an uninterrupted, aesthetically pleasing linear drainage design that extends seamlessly across the floor. Additionally, the linear drain system 100 can allow for flexible installation in various wet floor areas, including wall-to-wall placements, adjacent to walls, or near entries and curbs, as it does not require additional spacing for maintenance access.

[0064] Furthermore, the lateral offset of the access opening 108 can faciliate easier installation in a tile floor. Because the access opening 108 can be tiled over away from the drain inlet 104 and later cut into through tile for access (as discussed below), an installer can lay tile right up to the drain inlet 104 without making complicated cuts or measurements to accommodate the access opening 108. For example, the linear drain system 100 can be installed in a tile floor with mosaic tiles without requiring cutting or measuring to fit around an irregularly shaped inlet or large tray as with known linear drain systems.

[0065] In one embodiment, the linear drain system 100 includes a cover member 110 with an elongated portion 112 forming part of the drain inlet 104 and an access portion 114 at least in part covering the access opening 108. The access portion 114 can be partially cut out during installation, providing selective access to the access opening 108, outlet portion9 / 38 Docket No. 20086.106.1a106, and drain pipe for future or operational maintenance. It will be appreciated that the linear drain system 100 can be constructed from plastic or other durable materials.

[0066] According to an embodiment, the linear drain system 100 comprises a flat or planar bottom extending from the longitudinal ends toward the outlet portion 106, simplifying installation on or within a subfloor. Additionally, the linear drain system 100 can include a coupling system 116 with one or more receiving spaces 118 at the longitudinal ends. The one or more receiving spaces 118 can cooperate with one or more joint components (described below) to create secure, waterproof connections between multiple drain units or other components of the linear drain system 100 in a wet floor area. In an embodiment, the flat bottom and the coupling system 116 are configured to allow the drain length to be adjusted through field cutting, ensuring a precise fit in different floor layouts. In an embodiment, the one or more receiving spaces 118 and the associated joint components are arranged such that joining of drain bodies or extension members does not require underlapping of the drain body 102 or positioning of components beneath the bottom surface of the drain body 102. The coupling system 116 therefore advantageously can presen e the flat or planar bottom of the drain body 102 across joined sections and avoids any increase in height at the joint location.

[0067] The coupling system described herein can be configured to form a spliced or interlocking connection between the drain body and adjacent components. As used herein, '“interlock” and '“interlocking” refer to mating engagement between components, including interdigitating, overlapping, keyed, or finger-like features, that resist relative movement in at least one direction and may be used with or without adhesive. Engagement between the receiving spaces and the joint components resists relative movement in multiple directions and maintains alignment between joined components during installation and use. This arrangement contributes to structural stability and enables field adjustment of drain length while preserving a consistent vertical profile of the linear drain system.

[0068] In certain embodiments, the coupling system can be configured such that joint components are received entirely within the receiving spaces formed in the drain body and adjacent components and do not extend beneath a bottom surface of the drain body when installed. As a result, the coupling system does not underlap the drain body or create a raised condition at a joint location. This allows the drain body and any joined extension members or drain bodies to rest directly on a subfloor with a substantially flat bottom surface, thereby maintaining a consistent installed height along a length of the linear drain system.10 / 38 Docket No. 20086.106.1a

[0069] Referring to Fig. 1, a plurality of openings 120 are distributed along an upper surface of the drain body 102 and / or the cover member 110. The plurality of openings 120 are configured to cooperate with one or more trim members, as described below. For example, one or more of the plurality of openings 120 can be sized and configured to receive proj ections or locating posts extending from the one or more trim members, thereby securing the one or more trim members to the upper surface of the drain body 102 along the drain inlet 104. This arrangement improves the transition between the tile floor and the drain inlet 104 by reinforcing adjacent tiles and enhancing overall aesthetics through framing of the drain inlet 104 with a consistent, finished appearance.

[0070] In the illustrated embodiment, the upper surface of the drain body 102 slopes inward toward the drain inlet 104 from opposing sides, thereby defining a two-slope configuration. This configuration facilitates efficient drainage in installations positioned away from walls or entries. In other embodiments, the linear drain system 100 can be configured for placement adjacent to a wall or near an entry. The linear drain system 100 further includes one or more mounting rings 122 defining openings sized and configured to receive fasteners, thereby facilitating secure attachment of the drain body 102 to a subfloor.

[0071] As shown in Fig. 2, the drain inlet 104 and the access opening 108 are each in fluid communication with the outlet portion 106. A drain channel 124 extends along a length of the drain body 102 and slopes downward toward the outlet portion 106 to facilitate efficient water flow. The drain channel 124 defines an upward-facing opening positioned beneath the drain inlet 104 and configured to promote efficient drainage. In an embodiment, the drain channel 124 has a minimum slope of about 1 degree and includes a first section 126 having a narrow configuration with a width of approximately 1 / 2 inch to 5 / 8 inch. The first section 126 transitions into a wider second section 128 having a minimum slope of about 3 degrees, which in turn leads into a more steeply sloped conical or cylindrical section configured to direct water into the outlet portion 106.

[0072] According to an embodiment, the drain channel 124 is substantially free of columns or other internal obstructions. This obstruction-free configuration facilitates efficient water flow through the drain channel 124, reduces debris accumulation, and decreases the likelihood of clogging within the linear drain system 100. The open interior of the drain channel 124 permits water to flow with reduced turbulence or resistance, thereby enhancing overall drainage performance. Additionally, the absence of columns or protrusions within the drain channel 124 helps simplify cleaning and maintenance, as a11 / 38 Docket No. 20086.106.1aconventional drain cleaning brush can be readily inserted and maneuvered through the drain channel 124 without encountering obstacles. This configuration helps maintain the drain channel 124 in a clear and functional condition over extended periods of use.

[0073] Additionally, the cover member 110 extending over the drain channel 124 is configured to be supported on the drain body 102 along at least a portion of a periphery' of the cover member 110 without any supporting columns or obstructions positioned beneath the cover member 110 within the drain channel 124. This configuration maintains structural integrity of the cover member 110 while permitting unobstructed water flow through the drain channel 124 and into the outlet portion 106. By eliminating potential blockages beneath the cover member 110, the linear drain system 100 reduces the likelihood of water pooling or backing up at the drain inlet 104 and ensures that incoming water is efficiently directed into the drain channel 124. This configuration further improves accessibility for maintenance and inspection, as there are no structural elements interfering with visual assessment or manual cleaning of the drain channel 124.

[0074] The upper surface of the drain body 102 is substantially free of obstructions, which simplifies installation of tiles over the linear drain system 100 and allows trim members to be positioned neatly along the drain inlet 104. The smooth and continuous upper surface facilitates placement of finishing materials w ithout interference, contributing to a clean, uniform, and aesthetically pleasing installation.

[0075] In Figs.3 and 4. a ribbed structure 119 is shown formed on the bottom of the drain body 102. Structural reinforcement provided by the ribbed structure 119 can help reduce weight of the drain body 102 while maintaining strength to support tile loads and other applied forces. In an embodiment, the ribbed structure 119 at least in part defines the one or more receiving spaces 118 of the coupling system 116, which extend along the bottom of the drain body 102 from the longitudinal ends and terminate before the outlet portion 106.

[0076] As seen in Figs. 4 and 5, the one or more receiving spaces 118 can include at least one first receiving space 130 and at least one second receiving space 132. The first receiving space 130 can be located laterally related to the drain inlet 104 beneath the upper surface of the drain body 102 and sized and configured to accommodate larger joint components, providing additional support and create a watertight seal between drain sections. In an embodiment, the at least one first receiving space 130 may have a rectangular or other suitable shape and extends with a constant height or cross section from the longitudinal ends toward the outlet portion 106. It will be appreciated the at least one12 / 38 Docket No. 20086.106.1afirst receiving space 130 can include one, two, three, or any other number of first receiving spaces.

[0077] According to an embodiment, the at least one second receiving space 132 is located beneath the drain channel 124 and extends along a length of the drain inlet 104. The at least one second receiving space 132 is sized and configured to receive one or more joint components configured to splice or extend the drain channel 124 and / or to form a watertight seal between the dram body 102 and other linear drain systems or components. In an embodiment, the at least one second receiving space 132 comprises a groove and has a varying height along a length of the drain body 102. For example, the at least one second receiving space 132 can define a height H that decreases from a longitudinal end of the drain body 102 at Hl toward the outlet portion 106 at H2, as shown in Fig. 5. In some embodiments, the variation in height H of the at least one second receiving space 132 corresponds to a change in slope of the drain channel 124.

[0078] The at least one second receiving space 132 can have a substantially constant width along the length of the drain body 102. This configuration allows the drain body 102 to be cut or shortened while maintaining compatibility between the at least one second receiving space 132 and the j oint components. If the drain body 102 is cut such that a height of a joint component exceeds a height of the at least one second receiving space 132, one or more of the joint components can be configured to be ground, worn down, or sanded to be flush with a bottom of the drain body 102, thereby maintaining a substantially flat bottom surface of the drain body 102 to facilitate installation on a subfloor. This arrangement ensures that, even after field cutting and adjustment, the coupling system does not underlap the drain body or raise the drain body relative to the subfloor when the joint components are installed. In an embodiment, the joint component has a hollow configuration to facilitate sanding or grinding as needed.

[0079] It will be appreciated the at least one second receiving space 132 can have an oblong, rounded triangular, or any other suitable shape. The at least one second receiving space 132 can comprise one, two, three, or any other number of suitable receiving spaces.

[0080] Fig. 6 shows various examples of a plurality of joint components 134 that can be used with or included in the linear drain system 100. The plurality of joint components 134 can be made of plastic or other suitable materials, facilitate secure connections between drain bodies, extension members, walls, and other elements of the linear drain system 100 in a wet floor area.13 / 38 Docket No. 20086.106.1a

[0081] According to an embodiment, the plurality of joint components 134 includes at least one splice block 136 sized and configured to be received in the first receiving space 130 of the dram body 102. The at least one splice block 136 is selectively positionable in a sealing position or a splicing position. In the sealing position, an end of the at least one splice block 136 is aligned with a longitudinal end of the drain body 102, as shown in Figs.7 through 7B, thereby providing a bonding surface for attachment to a wall panel or other adjacent components and forming a waterproof and structurally secure connection. In the splicing position, an end of the at least one splice block 136 protrudes beyond the longitudinal end of the drain body 102, as shown in Figs. 12 and 12A, thereby allowing the at least one splice block 136 to splice or interlock with another linear drain system 100 or an extension member. In the splicing position, the splice block and splice sticks cooperate with the receiving spaces to interlock adjacent drain bodies or extension members, maintaining alignment and forming a flush, w atertight connection.

[0082] When positioned in the splicing position, the at least one splice block 136 facilitates the formation of a strong, watertight connection through friction and / or the use of adhesive, such as ABS glue, while maintaining a flush interface between connected components. In an embodiment, the at least one splice block 136 includes a groove 136A located near a central portion of the splice block 136. The groove 136A aids in positioning the splice block 136 within the first receiving space 130 during installation. For example, the groove 136A can assist an installer in positioning the at least one splice block 136 such that approximately one half of a length of the at least one splice block 136 protrudes from the longitudinal end of the drain body 102 when the splice block 136 is in the splicing position. Additionally, the at least one splice block 136 can reinforce the drain body 102 when installed in the first receiving space 130. In the splicing position, the splice block and any associated splice sticks engage corresponding receiving spaces while remaining flush with a bottom surface of the drain body and any joined component. This configuration avoids underlapping of the drain body and maintains a uniform vertical profile of the linear drain system across the spliced joint.

[0083] The groove 136A further enhances adhesive performance by increasing available bonding surface area, thereby improving mechanical attachment and sealing effectiveness between the at least one splice block 136 and adjoining components. This configuration promotes long-term durability and resistance to water infiltration. The at least one splice block 136 can be shaped to closely conform to the first receiving space 130. Optionally,14 / 38 Docket No. 20086.106.1athe at least one splice block 136 can include one or more cutouts 138 configured to interface with additional joint components to enhance structural integration.

[0084] In an embodiment, the plurality of joint components 134 includes one or more splice sticks 140, which may also be referred to as splice rods. The plurality of splice sticks 140 are sized and configured to be received in the at least one second receiving space 132 of the drain body 102. Similar to the at least one splice block 136, one or more of the plurality of splice sticks 140 is selectively positionable in a sealing position, as shown in Fig. 7, or a splicing position, as shown in Fig. 12. At least one of the plurality of splice sticks 140 can include a groove 140A positioned at or near a central portion thereof, which functions as a positioning aid and an adhesive capture feature. For example, the groove 140A can assist an installer in positioning the at least one of the plurality of splice sticks 140 such that approximately one half of a length of the splice stick 140 protrudes from the longitudinal end of the drain body 102 when in the splicing position. By increasing bonding surface area, the groove 140A enhances mechanical locking and improves the watertight integrity of the j oint.

[0085] One or more of the plurality of splice sticks 140 may be used individually or in combination, depending on desired connection strength and drainage configuration. In an embodiment, one or more of the plurality of splice sticks 140 have a finger-shaped or wedge-like configuration that allows them to be securely wedged into the at least one second receiving space 132 to form a firm and stable connection. In an embodiment, one or more of the plurality of splice sticks 140 have a rigid configuration. In other embodiments, one or more of the plurality' of splice sticks 140 are configured to conform, at least in part, to a shape of the at least one second receiving space 132.

[0086] Another joint component, an end step 142, is configured to support and / or seal a bottom portion of a wall panel spanning across a longitudinal end of the drain body 102, as shown in Fig. 7. The end step 142 can include one or more tabs 144 configured to interface with the one or more cutouts 138 correspondingly formed in the at least one splice block 136. This arrangement secures the end step 142 to the least one splice block 136 and reinforces the joint. The end step 142 can further include one or more grooves 142 A configured to aid in alignment and positioning while increasing adhesive contact surface area. These grooves enhance mechanical attachment and sealing effectiveness, thereby forming a robust and leak-resistant connection between components. It will be appreciated that the end step 142 can have a height selected based on a thickness of the wall panel and / or a size of a rabbet cut formed in the wall panel. In certain embodiments, the end step15 / 38 Docket No. 20086.106.1a142 cooperates with a side step formed on the drain body and / or an extension member to define a stepped perimeter region extending around at least a portion of the linear drain system. The stepped perimeter region is configured to receive wall panels on adjacent sides of the drain body, thereby enabling the linear drain system to be installed immediately adjacent to one or more walls while maintaining a continuous inlet and a watertight seal.

The angle member 146 can have an L-shaped configuration sized and configured to span and seal a joint located outside of the first receiving space 130 and the at least one second receiving space 132, as shown in Fig. 12. The angle member 146 is particularly useful for sealing a j oint that extends along a length of the drain body 102, such as in installations where the drain body 102 is recessed in a subfloor, including at a shower entry. The angle member 146 can include a groove 146 A configured to aid in alignment and positioning, thereby facilitating precise installation. By covering and sealing critical junctions, the angle member 146 enhances the overall integrity of the linear drain system 100 and provides long-term protection against leaks and structural movement.

[0088] Figs. 7 through 7B illustrate installation of the linear drain system 100 in a shower floor area according to an embodiment. The linear drain system 100 can be secured to a subfloor 10 and can extend between a wall panel 12 and a shower entry' 14 as shown in Fig. 7. Sloped floor panels 16 positioned on opposing sides of the linear drain system 100 direct water toward the drain inlet 104 to facilitate efficient drainage. As shown, longitudinal ends of the drain body 102 form flush and watertight connections with both the wall panel 12 and the shower entry 14. For example, the at least one splice block 136 can be installed in the first receiving space 130 in the sealing position, and one or more of a plurality of splice sticks 140 can be installed in the at least one second receiving space 132 in the sealing position as seen in Figs. 7A and 7B. Adhesive can be applied between the drain body 102, the joint components 134, and the shower entry 14 to form a watertight and seamless connection.

[0089] On the wall panel 12 side, the end step 142 can be connected to the at least one splice block 136 and arranged to bridge one or more rabbet cuts 18 formed in the sloped floor panels 16. Adhesive can further be applied between the drain body 102, one or more of the plurality' of joint components 134, and the wall panel 12 to enhance the watertight seal and provide durability and long-term performance in wet environments. In an embodiment, the end step 142 and a side step formed on the drain body 102 can together define a stepped perimeter that receives and supports the wall panel 12 along adjacent sides16 / 38 Docket No. 20086.106.1aof the drain body 102, thereby facilitating precise positioning of the linear drain system 100 relative to the wall panel while maintaining a flush and watertight installation.

[0090] Figs. 8 through 8C illustrate one or more trim members 148 according to an embodiment. Although the drawings depict embodiments having one or two trim members 148, the linear drain system 100 can accommodate three, five, or any other suitable number of trim members 148, depending on installation requirements.

[0091] As previously described, the one or more trim members 148 can be removably positioned on the drain body 102 during installation. As seen in Figs. 8 A and 8B, the one or more trim members 148 can include a plurality of projections 150 or locating posts distributed along a bottom surface thereof. The plurality of projections 150 can be sized and configured to align with and be received in the plurality of openings 120 distributed in the upper surface of the drain body 102 along a length of the drain inlet 104, thereby securing the one or more trim members 148 in position. This engagement between the one or more trim members 148 and the drain body 102 provides a precise and secure fit, creates a smooth transition between a tile floor and the drain inlet 104, and reinforces and protects adjacent tiles 20. This configuration can further enhance the appearance of the linear drain system 100 by neatly framing the drain inlet 104 and maintaining visual continuity with surrounding tiles 20.

[0092] In addition to providing functional benefits, the one or more trim members 148 contribute to the overall aesthetics of the linear drain system 100 by framing the drain inlet 104 in a clean and consistent manner. The one or more trim members 148 can be configured to accommodate tiles of varying sizes and thicknesses, including tiles having thicknesses of approximately 1 / 4 inch, 3 / 8 inch, or 1 / 2 inch. The one or more trim members 148 can be formed from plastic or other suitable materials and can be manufactured in a variety of finishes, including black, chrome, stone, white, or other desired finishes to complement different design preferences.

[0093] In an embodiment, the one or more trim members 148 have an elongated configuration and include a support part 152 and a retention part 154 extending upward from the support part 152 as best shown in Fig. 8B. When installed as shown in Fig. 8C, the support part 152 can provide support for tiles 20 from below, while the retention part 154 engages a sidewall of the tiles 20 to restrict lateral movement of the tiles 20 relative to the drain inlet 104. In an embodiment, the retention part 154 defines a height between the support part 152 and an upper end of the retention part 154. wherein the height is selected to correspond to a thickness of the tiles 20.17 / 38 Docket No. 20086.106.1a

[0094] In another embodiment, the retention part 154 has a trapezoidal or parallelogramlike cross-sectional shape such that opposing sides of the retention part 154 are not vertical. This configuration facilitates penetration and retention of grout between the tiles 20 and the one or more trim members 148, thereby improving long-term adhesion and stability. Additionally, the one or more trim members 148 can include a plurality of weep holes 156 configured to promote drainage and reduce water accumulation, further enhancing performance of the linear drain system 100.

[0095] Fig. 9 illustrates the linear drain system 100 installed in a tile floor 22 according to an embodiment. As shown, the linear drain system 100 extends between a shower entry 14 and a wall panel 12, with tiles 20 installed over an upper surface of the drain body 102 and sloping toward the drain inlet 104. The drain inlet 104 is lined with the one or more trim members 148 to provide a clean and visually integrated transition with the surrounding tile floor 22.

[0096] Due to a substantially flat bottom of the drain body 102 and the configuration of the coupling system 116, the linear drain system 100 can be attached directly to the subfloor without the use of shims or other leveling aids. The coupling system joins drain bodies, extension members, and other components without underlapping the drain body or raising the drain body relative to the subfloor. As a result, a consistent installed height is maintained along the length of the linear drain system 100, simplifying installation and improving long term stability.

[0097] The access opening 108 is laterally offset from the drain inlet 104 such that the access opening 108 does not interfere with or disrupt the drain inlet 104 wi thin the tile floor 22. This configuration permits the drain inlet 104 to extend continuously with minimal interruption between opposing ends of the linear drain system 100, thereby preserving a seamless appearance and enhancing overall aesthetics of both the linear drain system 100 and the surrounding tile floor 22. It will be appreciated that the lateral offset of the access opening 108 can provide easy and discrete access to the drain inlet 104 or the outlet portion 106 while preserving a required minimum inlet area of the drain inlet 104.

[0098] Figs. 10 through 11 illustrate a linear drain system 200 according to another embodiment. The linear drain system 200 can include any of the features described herein.

A plurality of openings 220 are distributed along an upper surface of the drain body 202 and the cover member 210. The plurality of openings 220 are sized and configured to cooperate with projections or locating posts extending from trim members to ensure precise positioning and secure attachment along the drain inlet 204. In the illustrated embodiment, the plurality of openings 220 are located only on one side of the drain inlet 204, as trim members are installed solely on a side of the drain inlet 204 opposite an adjacent wall panel. The drain body 202 further includes a drain channel 224 extending along a length of the drain body 202 and sloping downward toward the outlet portion 206. As in other embodiments, the drain channel 224 is configured to permit unimpeded water flow and is substantially free of columns or other obstructions, thereby facilitating cleaning. Additionally, the cover member 210 extending over the drain channel 224 is supported without any columns or obstructions beneath the cover member 210 within the drain channel 224. This configuration maintains structural integrity while allowing unobstructed water flow from the drain inlet 204 into the drain channel 224 and reduces the likelihood of water pooling or backing up at the drain inlet 204. The absence of internal obstructions further improves accessibility for cleaning and maintenance.

[0100] The upper surface of the drain body 202 includes a single surface sloping toward the drain inlet 204 and can include a positioning guide 258 extending along a length thereof. In an embodiment, the positioning guide 258 can be configured to locate one or more trim pieces on the upper surface of drain body 202 via projections or locating spikes extending from the bottom of one or more trim pieces or other structures. In other embodiments, the positioning guide 258 can be configured to facilitate trimming of mesh tape during installation. In an embodiment, the positioning guide 258 comprises a notched groove extending along the upper surface of the drain body 202 between longitudinal ends thereof. The upper surface of the drain body 202 can further include one or more capture elements19 / 38 Docket No. 20086.106.1a260 comprising a plurality of pockets sized and configured to receive sealant or other materials during installation, thereby enhancing bonding and waterproofing.

The side step 262 is configured to position and support a wall panel installed on the drain body 202 and extending parallel to the drain inlet 204. In certain embodiments, the side step 262 can cooperate with an end step 142 positioned at a longitudinal end of the drain body 202 to define at least a portion of a stepped perimeter around the drain body 202. The stepped perimeter helps support and locate wall panels extending along adjacent sides of the drain body 202, thereby facilitating installation of the linear drain system 200 at or near walls while maintaining a flush and watertight interface. As shown in Fig. 11, the linear drain system 200 can be installed on a subfloor 10A adjacent a wall panel 12A, with a single sloped floor panel 16A directing water toward the drain inlet 204. The wall panel 12A can be mounted onto an end step 142 and the side step 262 of the drain body 202. Additionally, longitudinal ends of the linear drain system 200 can extend wall to wall within the shower or tile floor area to provide a seamless installation.

[0102] Similar to other embodiments of the disclosure, the linear drain system 200 includes a coupling system 216 comprising one or more receiving spaces 218 formed in longitudinal ends of the drain body 202. The one or more receiving spaces 218 are sized and configured to cooperate with one or more of the plurality of joint components 134 to form flush, secure, and watertight connections with adjacent linear drain systems, linear drain components, or other shower or wet floor elements. The drain body 202 includes a substantially flat or planar bottom extending from the longitudinal ends toward the outlet portion 206, thereby facilitating installation on a subfloor and permitting on-site length adjustment when needed. Additionally, one or more of the plurality of thejoint components 134 can be installed at selected locations along the length of the drain body 202 to provide increased flexibility during installation.

[0103] In the illustrated embodiment shown in Fig. 10A, the one or more receiving spaces 218 include a first receiving space 230 configured to receive and engage the at least one splice block 136 and at least one second receiving space 232, shown as three receiving spaces, configured to receive and engage one or more of the plurality' of splice sticks 140.

[0113] Fig. 14 illustrates installation of the linear drain system 300 in a tile floor 22B at an entry’ of a wet floor area according to an embodiment. The horizontal flange 362 of the drain body 302 can be attached to a subfloor using a plurality of fasteners and aligned with an adjacent dry’ area. A lower portion of the drain body 302 can be secured to a recessed subfloor section 10B within the wet floor area, thereby allowing the tile floor 22B to slope toward the drain inlet 304 and the entry to form a barrier-free transition. The one or more trim members 148 are secured within one or more of the plurality of openings 320 along the drain inlet 304 to provide a smooth transition between the tile floor 22B and the drain inlet 304 while reinforcing and protecting adjacent tiles 20B.

[0114] This configuration enhances aesthetics of the linear drain system 300 by framing the drain inlet 304 in a clean and consistent manner relative to surrounding tiles 20B. As shown, a hole can be formed in a tile 20B positioned over the access opening 308 to permit future access for maintenance.

[0115] Fig. 15 illustrates the linear drain sy stem 300 installed at an entry' of a wet floor area and extending wall to wall according to an embodiment. A sloped floor panel 16B directs water toward the drain inlet 304 to facilitate efficient drainage. Similar to other embodiments, longitudinal ends of a plurality’ of extension members 364 form flush and watertight connections w ith opposing wall panels 12B and w ith the drain body 302. The access opening 308 is laterally offset from the drain inlet 304 such that the access opening 308 does not interfere with or disrupt the drain inlet 304 within the tile floor 22B. This configuration permits formation of a seamless, continuous inlet with minimal interruption23 / 38 Docket No. 20086.106.1abetween opposing ends of the linear drain system 300, thereby preserving aesthetic continuity and enhancing the overall appearance of the tile floor 22B.

[0116] Figs. 16A through 16H illustrate various steps of a method for accessing the access opening 308 in a tile floor 22C according to an embodiment. Step 401 includes positioning a hole drill guide 480 on a tile 20C located over the access opening 308, as shown in Figs. 16A and 16B. In an embodiment, the cover member 310 includes a boss 366 configured to interact with a slot defined in the hole drill guide 480 when the cover member 310 is installed on the drain body 302 and the tile 20C is installed over the cover member 310. The hole drill guide 480 is sized and configured such that, when engaged with the boss 366, an opening 482 of the hole drill guide 480 is aligned or substantially aligned with the access opening 308 beneath the tile 20C and the cover member 310.

[0117] Step 403 includes cutting a hole 24C through the tile 20C and the cover member 310, as show n in Figs. 16C and 16D. In an embodiment, this step includes using a hole saw 484 through the opening 482 of the hole drill guide 480 to form the hole 24C. The hole saw 484 can comprise a cylindrical cutting bit configured to form a generally cylindrical hole 24C extending through the tile 20C and the cover member 310 into the access opening 308.

[0118] Step 405 includes forming a bevel 26C on the tile 20C around the hole 24C, as shown in Figs. 16E and 16F. In an embodiment, the bevel 26C is formed using a conical bit 486. A gauge 488 can be used to verify a desired bevel angle and depth of the hole 24C. For example, an installer can form an initial cut with the conical bit 486 and then insert the gauge 488 into the hole 24C. If an upper surface of the gauge 488 extends above a surface of the tile 20C, the gauge 488 can be removed and an additional cut can be formed with the conical bit 486. This process can be repeated until the upper surface of the gauge 488 is substantially flush with the surface of the tile 20C.

[0119] Step 407 includes installing an access cover member into the hole 24C, as shown in Figs. 16G and 1 H. The access cover member can comprise a hole cover 490 having a portion defining an outer shape 492 that corresponds to the bevel 26C formed in the hole 24C, thereby providing a secure fit against the surrounding tile 20C. The hole cover 490 is further configured to receive and retain a tile piece 21 removed from the tile 20C during formation of the hole 24C.

[0120] The hole cover 490 includes a base and a rim extending upw ard from the base to define a cavity sized to receive the tile piece 21. The tile piece 21 can be secured within the cavity using adhesive. When installed, the hole cover 490 integrates with the surrounding tile 20C to form a substantially continuous tiled surface. The close fit and alignment of the24 / 38 Docket No. 20086.106.1ahole cover 490 relative to the surrounding tile 20C, together with the beveled interface, reduce visible transitions between the hole cover 490 and the surrounding tile 20C.

[0121] The hole cover 490 is positioned laterally offset from the drain inlet 304 of the linear drain system 300. To remove the hole cover 490, an adhesive-based or suction-based tool can be temporarily attached to the tile piece 21 to allow removal of the hole cover 490 from the hole 24C. This configuration permits access to the outlet portion 306 for cleaning and maintenance while maintaining a cohesive appearance of the tiled surface. Optionally, the hole cover 490 can include one or more features configured to interact with a hair trap positioned within the outlet portion 306 and / or a connected drain pipe during use of the linear drain system 300.

The upper surface of the drain body 602 can be substantially free of obstructions, which simplifies installation of tiles over the linear drain system 600 and allows one or more trim members 148 to be positioned neatly along the drain inlet 604. The smooth and continuous upper surface facilitates placement of finishing materials without interference, contributing to a clean, uniform, and aesthetically pleasing installation.26 / 38 Docket No. 20086.106.1a

[0127] In the illustrated embodiment, the drain body 602 further defines a side step 662 extending along a length of the drain body 602 as best shown in Fig. 18A. The side step 662 can form a step down relative to the upper surface of the drain body 602. The side step 662 can be configured to position and support a wall panel installed on the drain body 602 and extending parallel to the drain inlet 604. This beneficially allows the linear drain system 600 to be positioned immediately adjacent to one or more walls in a tiled floor area. As shown in Fig. 21, the linear drain system 600 can be installed on a subfloor adjacent to one or more wall panels 12E, with a floor panel sloping toward the drain inlet 604. The one or more floor panels 12E can be mounted onto the end step 142 and the side step 662 of the drain body 602. This configuration permits the inlet to extend continuously along the tile floor, enhancing drainage performance and preserving a seamless, aesthetically pleasing appearance. In certain embodiments, the side step 662 cooperates with an end step 142 positioned at a longitudinal end of the drain body 602 or an attached extension member 664 to define at least a portion of a stepped perimeter surrounding the drain body 602. The stepped perimeter is configured to receive and support wall panels extending parallel and perpendicular relative to the drain inlet 604, thereby facilitating installation of the linear drain system 600 immediately adjacent to one or more walls while preserving a continuous inlet and a watertight seal.

[0128] Referring to Figs. 18 and 18B, the cover member 610 can include an elongated portion 612 forming part of the drain inlet 604 and an access portion 614 at least in part covering the access opening 608. As described herein, the access portion 614 can be configured to be partially cut out during installation, providing selective access to the access opening 608, outlet portion 606, and / or a drain pipe for cleaning or maintenance. Optionally, the cover member 610 can include an access cover member 694 removably positionable within an opening defined in the cover member 610. The access cover member 694 can be sized and configured to support a tile member forming at least a portion of a tile floor extending over the cover member 610. The access cover member 694 can be sized and positioned to not or minimally interfere with a required minimum inlet area of the drain inlet 604. To access the access opening 608 of the drain system 600 in a tiled floor, the tile member and the access cover member 694 can be selectively lifted or removed from the cover member 610, thereby providing selective access to the access opening 608, the outlet portion 606, and / or a drain pipe for cleaning or maintenance.

[0129] In the illustrated embodiment, the access cover member 694 has a square or rectangular configuration. The access cover member 694 can include a boss 666 configured27 / 38 Docket No. 20086.106.1ato interact with a slot defined in the hole drill guide 480 (shown in Fig. 16B). In other embodiments, a lower surface of the access cover member 694 can include a connector 696 that is sized and configured to interact with or anchor one or more hair traps installed in the outlet portion 606 of the drain body 602. Some hair traps usable with the access cover member 694 and the linear drain systems of the present disclosure, including hair traps configured to attach to or be anchored by the access cover member 694. are described in U.S. application no. 19 / 453,894, filed January 20, 2026, incorporated by reference and belonging to the assignee of this disclosure.

[0130] Referring to Figs. 19 through 19B, the linear drain system 600 further includes first and second extension members 664 configured to integrate with the drain body 602 according to an embodiment. The first and second extension members 664 can be configured to include a substantially similar structure as the drain body 602 and to collectively form a continuous drainage path when joined. The first and second extension members 664 can be selectively attached to respective longitudinal ends of the drain body 602.

[0131] Similar to other embodiments, the linear drain system 600 includes a coupling system 616 having one or more receiving spaces 618 formed at longitudinal ends of the drain body 602. The one or more receiving spaces 618 can be sized and configured to cooperate with one or more of the plurality of joint components 134 to form flush, secure, and watertight connections with adjacent linear drain systems, extension members, or other wet floor components. The drain body 602 can include a substantially flat bottom extending from the longitudinal ends toward the outlet portion 606, thereby permitting on-site length adjustment. The plurality of joint components 134 can be installed at selected locations along the drain body 602 to provide increased fl ex i bi 1 i ty during installation.

[0132] In the illustrated embodiment, the one or more receiving spaces 618 include a first receiving space 630 sized and configured to receive the at least one splice block 136 and at least one second receiving space 632, sized and configured to receive one or more of the plurality of splice sticks 140. A ribbed structure 619 is shown formed on the bottom of the drain body 602. Structural reinforcement provided by the ribbed structure 619 can help reduce weight of the drain body 602 w hile maintaining strength to support tile loads and other applied forces. In an embodiment, the ribbed structure 619 at least in part defines the one or more receiving spaces 618 of the coupling system 616, which extend along the bottom of the drain body 602 from the longitudinal ends and terminate before the outlet portion 606.28 / 38 Docket No. 20086.106.1a

[0133] In the linear drain system 600, the coupling system 616 can be configured such that one or more joint components are received within the receiving spaces 618 formed in the drain body 602 and any attached extension members 664 without extending beneath a bottom surface of the drain body 602. The coupling system 616 thereby can join the drain body 602 and the extension members 664 without underlapping the drain body 602 and without increasing a height of the drain body 602 relative to a subfloor or other support surface. This configuration maintains a substantially flat bottom surface across joined sections of the linear drain system 600, allowing the drain body 602 and the extension members 664 to rest directly on a subfloor or other support surface and facilitating wall to wall installation without shims or height compensating elements.

[0134] As described in other embodiments, the first receiving space 630 can be located laterally related to the drain inlet 604 beneath the upper surface of the drain body 602 and sized and configured to accommodate larger joint components, providing additional support and create a watertight seal between drain sections. In an embodiment, the at least one first receiving space 630 may have a rectangular or other suitable shape and extends with a constant height or cross section from the longitudinal ends toward the outlet portion 606. It will be appreciated the at least one first receiving space 630 can include one, two, three, or any other number of first receiving spaces.

[0135] According to an embodiment, the at least one second receiving space 632 is located beneath the drain channel 624 and extends along a length of the drain inlet 604. The at least one second receiving space 632 is sized and configured to receive one or more of the plurality of joint components 134 configured to splice or extend the drain channel 624 and / or to form a watertight seal between the drain body 602, extension members 664, and other linear drain systems or components. In an embodiment, the at least one second receiving space 632 comprises a groove and has a varying height along a length of the drain body 102. For example, the at least one second receiving space 632 can define a height that decreases from a longitudinal end of the drain body 602 toward the outlet portion 606. In some embodiments, the variation in height of the at least one second receiving space 632 corresponds to a change in slope of the drain channel 624.

[0136] The at least one second receiving space 632 can have a substantially constant width along the length of the drain body 602. This configuration allows the drain body 602 to be cut or shortened while maintaining compatibility between the at least one second receiving space 632 and one or more of the plurality of joint components 134. If the drain body 602 is cut such that a height of ajoint component 134 exceeds a height of the at least29 / 38 Docket No. 20086.106.1aone second receiving space 632. one or more of the plurality of joint components 134 be configured to be ground, worn down, or sanded to be flush or substantially flush with a bottom of the drain body 602, thereby maintaining the substantially flat bottom surface of the drain body 602 to facilitate installation on a subfloor. In an embodiment, one or more of the plurality of joint components 134 have a hollow configuration to facilitate sanding or grinding as needed.

[0137] It will be appreciated the at least one second receiving space 632 can have an oblong, rounded triangular, or any other suitable shape. The at least one second receiving space 632 can comprise one, two, three, or any other number of suitable receiving spaces. As with other embodiments, the at least one splice block 136 and one or more of the plurality of splice sticks 140 can be selectively positionable in sealing positions or splicing positions, as desired. The end step 142 can be securely attached to the at least one splice block 136 to provide a stable and watertight connection between the extension member 664 and the drain body 602 and wall panel.

[0138] Figs. 19A and 19B provide detailed views of the linear drain system 600, illustrating attachment of the extension member 664 to the drain body 602 according to an embodiment. To secure the extension member 664, the at least one splice block 136 is positioned and adhered within the first receiving space 630 in a splicing position. Similarly, one or more of the plurality of splice sticks 140 are positioned and adhered within the at least one second receiving space 632. Protruding portions of the at least one splice block 136 and the one or more of the plurality of splice sticks 140 are then inserted into and adhered within corresponding receiving spaces formed in the extension member 664 to form a flush and watertight connection.

[0139] Optionally, one or more grooves formed in the at least one splice block 136 and one or more of the plurality of splice sticks 140 facilitate accurate positioning and enhance connection strength. Additionally, the least one splice block 136 and one or more of the plurality of splice sticks 140 can be attached to a free longitudinal end of the extension member 664 in a sealing position, with an end step 142 connected to the at least one splice block 136. The end step 142 can form a step down at the longitudinal end of the drain system 600 relative to the upper surface of the drain body 602. The end step 142 can be sized and configured to position and support a wall panel installed on the extension member 664 or the drain system 600 and extending in a direction perpendicular to or non-parallel relative to the drain inlet 604. This beneficially allows the linear drain system 600 to be positioned immediately adjacent to one or more walls in a tiled floor area. This30 / 38 Docket No. 20086.106.1aconfiguration can further help form flush and watertight seals between the extension member 664 or the drain system 600 and a wall panel or other adjacent components.

[0140] As shown in Figs. 20 and 21, the one or more trim members 148 can be removably positioned on the drain body 602 during installation. In an embodiment, the one or more trim members 148 can be positioned on the drain body 602 along the side of the drain inlet 604 opposite the wall panel 12E forming the back wall of the tile floor area.

[0141] Like in other embodiments, the one or more trim members 148 can include a plurality of projections 150 or locating posts distributed along a bottom surface thereof. The plurality of projections 150 can be sized and configured to align with and be received in the plurality of openings 620 distributed in the upper surface of the drain body 602 along a length of the drain inlet 604, thereby securing the one or more trim members 148 in position. This engagement between the one or more trim members 148 and the drain body 602 helps provide a precise and secure fit, creates a smooth transition between a tile floor and the drain inlet 604, and reinforces and protects adjacent tiles. This configuration can further enhance the appearance of the linear drain system 600 by neatly framing the drain inlet 604 and maintaining visual continuity with surrounding tiles.

[0142] In addition to providing functional benefits, the one or more trim members 148 contribute to the overall aesthetics of the linear drain system 600 by framing the drain inlet 604 in a clean and consistent manner. The one or more trim members 148 can be configured to accommodate tiles of varying sizes and thicknesses, including tiles having thicknesses of approximately 1 / 4 inch, 3 / 8 inch, or 1 / 2 inch. The one or more trim members 148 can be formed from plastic or other suitable materials and can be manufactured in a variety of finishes, including black, chrome, stone, white, or other desired finishes to complement different design preferences.

[0143] In an embodiment, the one or more trim members 148 have an elongated configuration and include a support part 152 and a retention part 154 extending upward from the support part 152. When installed, the support part 152 provides support for one or more tiles from below, while the retention part 154 engages a sidewall of the one or more tiles to restrict lateral movement of the one or more tiles relative to the drain inlet 604. In an embodiment, the retention part 154 defines a height selected to correspond to a thickness of the one or more tiles.

[0144] In another embodiment, the retention part 154 has a trapezoidal or parallelogramlike cross-sectional shape such that opposing sides of the retention part 154 are not vertical. This configuration facilitates penetration and retention of grout between the one or more31 / 38 Docket No. 20086.106.1atiles and the one or more trim members 148, thereby improving long-term adhesion and stability’. Additionally, the one or more trim members 148 can include a plurality’ of weep holes 156 configured to promote drainage and reduce yvater accumulation, further enhancing performance of the linear drain system 600.

[0145] In an embodiment, the one or more trim members 148 include a trim member 148 A configured to be installed on the drain body 602 and to frame the access cover member 694 when the access cover member 694 is positioned in the cover member 610, or to frame the underlying opening when the access cover member 694 is removed. For example, the trim member 148A can have a generally U-shaped or three-sided frame configuration defining an open interior region. The trim member 148A can include a pair of generally parallel longitudinal portions connected by a transverse portion, such that the trim member 148 A surrounds at least three sides of the access cover member 694. A wallfacing side of the trim member 148 A can be substantially flat or otherwise arranged to interact with a tray 690. The tray 690 can be configured to be removable from the tile floor 22E and to carry a tile piece 2 IE. The configuration of the trim member 148A beneficially allows the trim member 148 A to finish and protect at least a portion of the perimeter of the tray 690. In an embodiment, the tray 690 can include a base and a rim extending upward from the base to define a cavity’ sized to receive the tile piece 21E. Optionally, the tile piece 21E can be secured within the cavity using an adhesive. When installed in the tile floor 22E, the tray 690 can integrate yvith the surrounding tile floor 22E to form a substantially continuous tiled surface. The close fit and alignment of the tray 690 relative to the surrounding tile floor 22E can help reduce visible transitions betyveen the tray 690 and the surrounding tile floor 22E. When the tray 690 is removed, a user can access the access opening 608 or outlet portion 606 of the linear drain system 600 in the tile floor 22E for cleaning or maintenance.

[0146] Figs. 21 illustrates the linear drain system 600 installed in a tile floor 22E according to an embodiment. As shown, the linear drain system 600 extends along a wall panel 12E and between opposing wall panels 12E comprising side walls, with the tile floor 22E installed over the upper surface of the drain body 602 and sloping toward the drain inlet 604. At least one side of the drain inlet 604 can be lined with one or more of the trim members 148 to provide a clean and visually integrated transition with the surrounding tile floor 22E. Due to a substantially flat bottom of the drain body 602, the linear drain system 600 can be attached directly to the subfloor without the use of shims or other leveling aids, thereby simplifying installation. Additionally, the coupling system 616 allows longitudinal32 / 38 Docket No. 20086.106.1aends of the linear drain system 600 comprising the extension members 664 to align flush with and seal against both the wall panels 12E forming side walls of the tiled floor area or wet floor area. In addition, the side step 662 of the drain body 602 positions and supports the wall panel 12E forming the back wall of the tiled floor area or wet floor area on the drain body 602, thereby facilitating a watertight connection and promoting efficient drainage. The tray 690 carrying the tile piece 21E is removably installed over the access cover member 694 on the drain body 602, reducing visible transitions between the tile floor 22E and the tile piece 2 IE.

[0147] Like in other embodiments, the access opening 608 can be laterally offset from the drain inlet 604 such that the access opening 608 does not substantially interfere with or disrupt the drain inlet 604 within the tile floor 22E. This configuration permits the drain inlet 604 to extend continuously with minimal interruption between the wall panels 12E and opposing ends of the linear drain system 600, thereby preserving a seamless appearance and enhancing overall aesthetics of both the linear drain system 600 and the surrounding tile floor 22E.
