Description

[0001] The invention relates to a sanitary installation for defining a shower area and for forming a sanitary unit. Furthermore, the invention relates to a primary functional module for defining a shower area and a secondary functional module for forming a sanitary unit, as well as an assembly method.

[0002] Sanitary installations are used to design bathrooms and include room dividers such as glass shower enclosures or masonry partitions. Sanitary furniture, as shown for example in EP 3705009 A1, is attached to such room dividers.

[0003] Bathrooms are getting bigger, and so are shower areas. Walk-in showers are frequently used. These are level-entry showers, separated from the rest of the bathroom by a shower enclosure. Due to the increasing size of bathrooms, the space allocated for walk-in showers is also growing, requiring ever larger shower enclosures. These enclosures are sometimes built with masonry, requiring the involvement of a bricklayer in addition to a plumber. If, on the other hand, glass panels or other sheet materials attached to support rails are used to separate the shower area, their size presents particular challenges during transport and installation. Shower enclosures in modern bathrooms are often 2 x 2 meters in size.

[0004] Furthermore, it is desirable to increase the comfort of shower areas and bathrooms in general by providing sanitary furniture that is accessible from the shower area or utilizes the room-side surface of the shower area. This usually requires complex mounting systems that attempt to attach small shelves to shower enclosures. Alternatively, separate pieces of furniture can be placed in the immediate vicinity of the shower area on the room side to make this space more convenient for additional functions.

[0005] There is therefore a need to provide a sanitary installation of the type mentioned above, which facilitates the transport and installation of shower enclosures, while simultaneously increasing the comfort of bathrooms through sanitary furniture and allowing for individual, needs-based design.

[0006] This is where the invention comes in, the purpose of which is to provide a customizable sanitary installation for demarcating a shower area and forming a sanitary unit, which enables simplified transport, easy assembly and optimized use of space.

[0007] The invention solves the aforementioned problem by means of a sanitary installation according to claim 1, a primary functional module for forming a shower enclosure according to claim 22 and a secondary functional module for forming a sanitary unit according to claim 25 as well as an assembly method according to claim 28.

[0008] With regard to the first aspect of the invention, the aforementioned problem is solved by a sanitary installation of the type mentioned above, comprising at least one retaining rail, wherein the retaining rail extends vertically along a longitudinal axis in a mounted state, at least one primary functional module configured at least for separating a shower area, and at least one secondary functional module configured at least for forming a sanitary unit.The primary functional module engages with a section of the retaining rail along its longitudinal extent, comprising a shower-side primary functional module face, an opposite room-side primary functional module face, a primary functional module height that, in the assembled state, runs parallel to its longitudinal extent and is less than the longitudinal extent of the retaining rail, and two opposite primary functional module end faces extending orthogonally to the primary functional module height. The secondary functional module engages with a section of the retaining rail along its longitudinal extent.The secondary function module has a shower-side secondary function module surface, an opposite room-side secondary function module surface, a secondary function module height that, when installed, runs parallel to the longitudinal extent and is less than the longitudinal extent, and two opposite secondary function module end faces extending orthogonally to the longitudinal extent. At least one primary function module end face is at least indirectly connected to a first secondary function module end face. Thus, a modular sanitary installation is provided that is functionally integrated both for partitioning off a shower area and for providing sanitary furniture.Because the first primary function module end face is at least indirectly connected to the first secondary function module end face, the primary and secondary function modules form a continuous, uninterrupted surface on the shower area side, separating the shower area from the room. To create this continuous surface, the first primary function module end face preferably abuts the first secondary function module end face in such a way that the shower area-side surface of the primary function module and the shower area-side surface of the secondary function module are flush with each other, i.e., seamlessly aligned. Alternatively or additionally, the room-side surface of the primary function module and the room-side surface of the secondary function module are also flush with each other, i.e., seamlessly aligned.

[0009] The primary and secondary functional modules are held in position by the mounting rail and are thus permanently installed as part of the sanitary installation. In this configuration, the primary and secondary functional modules are mounted one above the other and engage with the mounting rail. The section of the mounting rail along its length that engages the primary functional module is therefore different from the section along its length that engages the secondary functional module.

[0010] The primary and secondary functional modules, held by the mounting rail, together form a shower enclosure with transversely divided modules, making it easier to install and transport. Simultaneously, at least the secondary functional module functions as a piece of bathroom furniture, allowing for functional integration beyond simply separating the shower area. This optimizes the use of available space and enhances comfort in the bathroom, particularly in the shower area. Furthermore, the integration of the bathroom furniture with the secondary functional module, which engages with the mounting rail, ensures easy installation and eliminates the need for drilling into bathroom walls or glass panels used to separate the shower area.

[0011] Further developments of the invention are specified in the dependent claims, which further develop the concept of the invention with regard to advantageous features within the scope of the problem statement and with regard to further advantages.

[0012] It is preferred that the first primary functional module end face abuts the first secondary functional module end face in a sealing manner. This facilitates the formation of the continuous surface on the shower tray side and ensures its watertightness. Preferably, a seal extending, in particular completely, along the first primary functional module end face and the first secondary functional module end face is provided between them. In this case, the first primary functional module end face indirectly abuts the first secondary functional module end face, with a seal provided between the end faces to establish the sealing contact between the first primary functional module end face and the first secondary functional module end face.Preferably, a seal extending, in particular completely, along the second primary functional module end face and the second secondary functional module end face is provided between them. In this case, the second primary functional module end face rests indirectly against the second secondary functional module end face, with a seal between the end faces to establish the sealing contact between the second primary functional module end face and the second secondary functional module end face. Thus, a continuous surface is still visually formed. The seal forms a sealing point that preferably extends completely along the respective primary functional module end face and the respective secondary functional module end face.

[0013] The sealing point is preferably covered on the shower tray side and / or the room side by a section of the primary or secondary functional module. In particular, the sealing point is concealed on the shower tray side and / or the room side by a projection extending along the first end face of the primary and secondary functional modules. The projection is designed such that the shower tray-side side surface of the primary and secondary functional modules is flush with each other, i.e., seamlessly integrated.

[0014] Preferably, the sanitary furniture is permanently mounted at a defined position on the secondary functional module. The sanitary furniture formed by the secondary functional module thus constitutes a fixed and spatially defined component of the sanitary installation and not merely a bathroom accessory that can be attached to the secondary functional module via mounting devices such as hooks or the like, or via movable hooks guided in a rail. However, the position of the sanitary furniture formed by the secondary functional module can vary along with the secondary functional module itself, allowing for a needs-based design of the sanitary installation. For example, two primary functional modules could be provided, with the secondary functional module positioned between them.

[0015] Preferably, the primary and secondary functional module end faces have a uniform width that extends orthogonally to the longitudinal axis. Because the primary and secondary functional module end faces have a uniform width, the entire sanitary installation also has a uniform width orthogonally to the longitudinal axis of the mounting rail.

[0016] According to a preferred embodiment, the primary function module has a primary groove extending along its width on the first end face, and the secondary function module has a secondary spring extending along its width on the same end face. Thus, in the assembled state, the primary groove on the first end face of the primary function module is in contact with the secondary spring on the same end face. Alternatively, the primary function module preferably has a primary spring extending along its width on the first end face, and the secondary function module has a secondary groove extending along its width on the same end face. In this configuration, the primary spring and the secondary groove are also in contact in the assembled state, since the first end face of the primary function module is in contact with the first end face of the secondary function module.A tongue-and-groove system provides a convenient and, in particular, gap-free mounting solution for the primary and secondary functional modules, eliminating the need for mounting rails between them. Preferably, a seal is arranged between the primary groove and the secondary tongue. This seals the transition between the functional modules.

[0017] If the primary functional module has a primary spring on its first end face, the primary functional module preferably includes a primary groove extending along its width on its second end face. Thus, the primary groove and primary spring are formed on opposite end faces of the primary functional module. If the secondary functional module has a secondary groove on its first end face, the secondary functional module preferably has a secondary spring extending along its width on its second end face. Thus, the secondary groove and secondary spring are also arranged on opposite end faces of the secondary functional module.It is therefore possible to mount the primary function module and the secondary function module alternately on top of each other, whereby a primary groove engages with a secondary spring and a primary spring engages with a secondary groove.

[0018] In the event that the primary function module has a primary groove on its first end face, the primary function module preferably has a primary spring extending along its width on its second end face, and the secondary function module, which has a secondary spring on its first end face, preferably has a secondary groove extending along its width on its second end face. Thus, each primary function module has a primary groove and a primary spring, and each secondary function module has a secondary groove and a secondary spring. Grooves and springs can therefore be alternately provided on the lower end face of the respective primary and secondary function modules when assembled, and can be connected to a primary spring provided on the upper end face of the adjacent primary function module when assembled.Secondary functional module come into play.

[0019] Preferably, the primary spring and the secondary groove are designed and engage with each other such that a receiving space and at least two opposing sealing surfaces are formed between the primary spring and the secondary groove on the shower tray side. Alternatively or additionally, the primary groove and the secondary spring are designed and engage with each other such that a receiving space and at least two opposing sealing surfaces are formed between the primary groove and the secondary spring on the shower tray side. The receiving space is configured to receive a base body of the seal, and the opposing sealing surfaces are configured to receive a sealing lip of the seal. Preferably, the base body of the seal is further configured to deform elastically when the respective spring and groove are engaged, such that it fills the receiving space, in particular completely.Preferably, the receiving space is formed between a distal contact surface of the spring and a section of the groove that is central with respect to the depth direction of the functional modules. The contact surface presses the base body into the groove so that the resulting receiving space is filled as completely as possible. Simultaneously, at least one sealing lip engages between the two opposing surfaces of the spring-groove connection on the shower tray side, thus achieving a seal between the primary and secondary functional modules that is not visible from the shower tray side. It should be understood that individual primary or secondary functional modules can also be sealed together using a corresponding spring-groove connection and a seal integrated therein.

[0020] Preferably, the primary functional module is a wall module designed exclusively for partitioning off a shower area. The wall module thus has no function beyond partitioning off the shower area. More preferably, the secondary functional module is a sanitary furniture module designed to form a sanitary unit. It should be understood that, in addition to forming a sanitary unit, the sanitary furniture module, by virtue of its arrangement adjacent to the primary functional module, simultaneously partitions off the shower area. The sanitary unit formed by the sanitary furniture module can be located on the room side and / or on the shower area side.

[0021] According to an alternative preferred embodiment, the primary functional module and the secondary functional module are designed as combined sanitary furniture and wall modules, each configured to partition off a shower area and to partially form a sanitary unit. In other words, one of the combined sanitary furniture and wall modules does not yet constitute a sanitary unit; rather, at least two adjacent sanitary furniture and wall modules are necessary to jointly form a complete sanitary unit.For example, a primary functional module, designed as a combined sanitary ware and wall module, can form the lower part of a storage compartment when installed. A secondary functional module, also designed as a combined sanitary ware and wall module, can then form the upper part of the storage compartment when installed above it. Together, the primary and secondary functional modules form a complete storage compartment with a lower boundary wall, two side walls, and a top boundary wall. This allows the size of the individual functional modules to be reduced without significantly restricting the overall size of the sanitary ware.

[0022] Preferably, the sanitary installation comprises at least two primary functional modules, in particular wall modules, each extending at least along 1 / 4, and in particular along at least 1 / 3, of its longitudinal extent. This ensures that the shower area is separated by means of the primary functional modules over a sufficiently large area along the longitudinal extent. This guarantees adequate protection against splashing water.

[0023] Preferably, at least one wall module is positioned below the sanitary furniture module when installed, and / or at least one wall module is positioned above the sanitary furniture module when installed. This ensures that the sanitary furniture module engages with the mounting rail in a roughly central area along its length, making the sanitary furniture easily accessible and preventing it from being positioned too high or too low.

[0024] Preferably, the secondary function module on the shower-side secondary function module side surface comprises one, several, or all of the following: a shelf, at least a section of a wall-integrated storage compartment, a mirror, or a bench. In the context of the invention, "wall-integrated" means that the storage compartment is recessed into the wall, i.e., extends from the wall surface into the wall and is thus flush with the wall.

[0025] Preferably, the secondary functional module also includes a heating element. In this case, the secondary functional module does not directly constitute a piece of furniture, but rather a functional element. In this case, the secondary functional module with a heating element represents an electrical functional module that, in addition to separating the shower area, also fulfills a heating function. Furthermore, the primary functional module can also include a heating element and thus constitute an electrical functional module.

[0026] A wall-integrated storage compartment, as used here, is understood to be a storage compartment that is flush with the wall, i.e., extends from the side surface into the wall. Such storage compartments can usually only be constructed of masonry, provided the structural conditions permit this. Similarly, shower benches are often constructed of masonry and tiled, so the invention also allows for a simplified integration of benches as sanitary furniture in this context. By means of a corresponding secondary function module, such sanitary furniture can be easily integrated into the shower area without requiring any structural modifications and is provided on the shower-side side surface of the secondary function module.

[0027] Preferably, the secondary functional module on the room-facing side panel includes one, several, or all of the following: a washbasin, a towel rail, a mirror, a bench, a cabinet, at least a section of a wall-integrated storage compartment, or a shelf. This means that sanitary furniture, such as washbasins or towel rails, does not need to be mounted on a wall, i.e., on the masonry, but can be provided by the sanitary installation on the secondary functional module. This reduces the installation time for sanitary fittings when designing bathrooms.

[0028] Preferably, the wall-integrated storage compartment formed on the shower side of the secondary function module has an access opening formed in the shower-side side surface of the secondary function module, a rear wall spaced from the access opening towards the room-side side surface of the secondary function module, and a frame surface extending from the rear wall to the access opening. Alternatively or additionally, the wall-integrated storage compartment on the room side has an access opening formed in the room-side side surface of the secondary function module, a rear wall spaced from the access opening towards the shower-side side surface of the secondary function module, and a frame surface extending from the rear wall to the access opening.

[0029] Preferably, the wall-integrated storage compartment also features a light source attached to the back panel or the frame. This provides additional illumination of the storage compartment, further enhancing comfort through improved lighting conditions.

[0030] Preferably, the wall-integrated storage compartment on the shower side forms a recess on the room side, designed to provide a shelf and / or a towel rail. The resulting bulge on the side facing away from the access opening, created by the wall-integrated storage compartment, is thus utilized to also function as bathroom furniture. This recess either provides additional storage space as a shelf and / or can alternatively or additionally be used as a towel rail attached to it.

[0031] Preferably, the mounting rail is a first mounting rail and the sanitary installation has a second mounting rail, wherein the first and second mounting rails are spaced at least as far apart as the width and are designed to accommodate the primary and secondary functional modules between them. Optionally, further primary or secondary functional modules can be accommodated between the mounting rails. The primary and secondary functional modules thus engage with the first and second mounting rails at opposite edges. This results in more uniform support of the primary and secondary functional modules by the two mounting rails. Furthermore, the edge areas of the primary and secondary functional modules are thus protected from media and the like by the first and second mounting rails.

[0032] The primary functional module and / or the secondary functional module are preferably made, at least partially, of at least one of the following materials: cast mineral, glass, or a polymer, in particular acrylic glass. Glass and polymers, such as acrylic glass, are translucent and thus provide better lighting conditions in the shower area. Cast mineral, on the other hand, has the advantage that it does not need to be squeegeed after showering to remove unwanted water deposits, which are visible on glass. Preferably, at least two primary functional modules and / or one primary functional module and one secondary functional module and / or at least two secondary functional modules are made of different materials. The modularity of the sanitary installation allows for the combination of different materials, which, at least on the shower area side, form a continuous surface.For example, a primary functional module made of glass can be located in the upper area of ​​the sanitary installation and a primary functional module made of cast mineral in the splash-prone lower area of ​​the sanitary installation, so that the cleaning effort is reduced, but at the same time sufficient light penetration is ensured.

[0033] According to a preferred embodiment, the retaining rail extends in a depth direction orthogonal to the longitudinal extent and width of the primary and secondary function modules in a range of 30 mm to 100 mm. The primary function module is a first primary function module and the secondary function module is a first secondary function module.The sanitary installation further comprises at least one of the following functional modules engaged with the retaining rail: a second primary functional module, which is spaced apart in the depth direction from the first primary functional module and has a primary functional module height corresponding to the first primary functional module; a second primary functional module, which is spaced apart in the depth direction from the first secondary functional module and has a primary functional module height corresponding to the first secondary functional module; a second secondary functional module, which is spaced apart in the depth direction from the first primary functional module and has a secondary functional module height corresponding to the first primary functional module; or a second secondary functional module, which is spaced apart in the depth direction from the first secondary functional module and has a secondary functional module height corresponding to the first secondary functional module.Thus, two functional modules are always arranged adjacent to each other in the direction of depth, i.e., side by side and engaged with the mounting rail. This provides one room-side functional module and one shower-side functional module, which have a corresponding height and are therefore essentially identical. This creates a cavity between each pair of adjacent primary or secondary functional modules, in which mounting interfaces, cable ducts, or hydraulic lines can be concealed.

[0034] It is further preferred that operating elements for a shower fitting and / or a control unit are provided on the mounting rail. The mounting rail thus not only engages with and holds the primary and secondary function modules in position, but also serves as a central operating interface, allowing the user to operate shower fittings, such as shower heads, or a control unit. The operating elements for a control unit are preferably a touch pad, which is preferably accommodated in a recess of the mounting rail. Preferably, the touch pad has a transparent glass or acrylic glass disc designed to seal an interior space within the mounting rail. The mounting rail is preferably connected to the control unit and / or incorporates a control unit.Preferably, at least one printed circuit board is arranged in the retaining strip or in a component directly connected to the retaining strip.

[0035] Preferably, the retaining rail extends in a depth range of 30 mm to 100 mm, with the shower-side primary functional module having a maximum distance of 100 mm from the room-side primary functional module and / or the shower-side secondary functional module having a maximum distance of 100 mm from the room-side secondary functional module. Thus, the primary and secondary functional modules can be deeper overall and have a functional module depth corresponding to the depth of the retaining rail. The partition for a shower area provided by the sanitary installation is therefore more solid overall and tends to resemble a masonry wall.

[0036] Preferably, the primary function module has a primary function module receptacle extending completely along the height of the primary function module, which is arranged centrally with respect to its width and configured to receive a section of the retaining rail. The primary function module receptacle engages, in particular, with a section of the retaining rail. Alternatively or additionally, the secondary function module comprises a secondary function module receptacle extending completely along the height of the secondary function module, which is arranged centrally with respect to its width and configured to receive a section of the retaining rail, and in particular to engage with a section of the retaining rail. This central arrangement eliminates the need for additional retaining rails while still ensuring stable attachment of the function modules to the retaining rail.Furthermore, the central arrangement of the retaining rails advantageously allows the attachment of operating elements, in particular sanitary operating elements for shower fittings or electrical operating elements for an electrical control device.

[0037] Preferably, the mounting rail, particularly if it is centrally located, includes a shower fitting, especially a shower head. The mounting rail preferably has a section that is horizontal in the depth direction and thus horizontal in the mounted state, on which the shower fitting, especially the shower head, is arranged.

[0038] According to a preferred embodiment, the secondary function module has an electrical inlet contact in the area of ​​the secondary function module receptacle, which is configured to engage with a corresponding electrical outlet contact of the mounting rail in the area of ​​the secondary section for the purpose of conducting current at a low voltage. According to an alternative embodiment, the secondary function module has an electrical inlet contact in a contact area with the first mounting rail and / or the second mounting rail, which is configured to engage with a corresponding electrical outlet contact of the mounting rail for the purpose of conducting current at a low voltage. In both embodiments, the inlet contact and the outlet contact are preferably plug-in contacts.Thus, an electrical connection is simultaneously provided in the area of ​​the mechanical connection between the secondary function module and the mounting rail. Preferably, the secondary function module has a sealed cable guide with at least one power cable that is conductively engaged with the outlet contact of the mounting rail via the inlet contact. The mounting rail is preferably connectable to a low-voltage connection in a wall or ceiling. Preferably, the cable guide in the secondary function module is implemented, at least partially, by a bore or an elongated recess that extends to a wall of the secondary function module to which an electrical load is connected. Preferably, the electrical load is an LED light for a wall-integrated storage compartment or a heating element.

[0039] The retaining rail preferably has one or more tightly sealed cable guides with at least one power cable, via which the outlet contact is connected to the low-voltage connection.

[0040] The invention solves the aforementioned problem in a second aspect by means of a primary functional module for a sanitary installation, in particular for a sanitary installation according to the first aspect of the invention. The primary functional module is designed at least for partitioning off a shower area and is configured to engage with a section of a retaining rail which, in a mounted state, extends vertically along its longitudinal extent.The primary function module, when assembled, has a shower-side primary function module surface, an opposite room-side primary function module surface, a primary function module height that, when assembled, extends vertically and thus, in particular, parallel to the longitudinal extent, and which is, in particular, less than the longitudinal extent of the mounting rail, and two opposite primary function module end faces that extend orthogonally to the primary function module height. According to the second aspect, the invention utilizes the advantages described at the outset with regard to the primary function module in connection with the first aspect of the invention by means of a corresponding primary function module.By dividing the primary function module transversely along the end faces, so that it can only be engaged with a section of the retaining rail along its longitudinal extension, the primary function module has smaller overall dimensions and thus enables simplified assembly and transport.

[0041] Preferably, the primary functional module is a wall module designed exclusively for partitioning off a shower area. Alternatively, the primary functional module is designed as a combined sanitary furniture and wall module, configured for partitioning off a shower area and for forming at least a section of sanitary furniture. Thus, the primary functional module fulfills the function of partitioning off a shower area and optionally allows for functional integration through the additional formation of sanitary furniture. The simultaneous formation of sanitary furniture eliminates further assembly work that would otherwise be necessary for attaching sanitary furniture to the rest of the room structure, particularly to walls.

[0042] The invention solves the aforementioned problem in a third aspect by means of a secondary functional module for a sanitary installation, in particular for a sanitary installation according to the first aspect of the invention. The secondary functional module is configured at least to form a sanitary unit and is further configured to engage with a section of a retaining rail extending vertically along a longitudinal dimension in a mounted state.The secondary function module has a shower-side secondary function module surface, an opposite room-side secondary function module surface, a secondary function module height that is vertical in the mounted state and thus, in particular, parallel to the longitudinal extent, and which is in particular less than the longitudinal extent of the mounting rail, and two opposite secondary function module end faces extending orthogonally to the longitudinal extent. A corresponding secondary function module for a sanitary installation takes advantage of the benefits described at the outset with regard to the first aspect of the invention by forming the sanitary furniture with a modular secondary function module, which can be easily engaged with a mounting rail.Preferred embodiments and advantages described in relation to the first aspect of the invention are also preferred embodiments and advantages according to the third aspect of the invention, and vice versa. A corresponding secondary functional module particularly facilitates assembly and eliminates assembly steps related to the spatial structure of a bathroom, especially the masonry. Furthermore, the modularity and the transverse division of the secondary functional module along its end faces, such that it engages only with a section along the longitudinal extent of the mounting rail, make the sanitary installation easy to assemble and transport.

[0043] Preferably, the secondary functional module is a sanitary furniture module configured to form a sanitary unit. Alternatively, the secondary functional module is a combined sanitary unit and wall module configured to separate a shower area and to form at least a section of a sanitary unit.

[0044] The invention solves the aforementioned problem in a fourth aspect by means of a method for assembling a sanitary installation, in particular a sanitary installation according to the first aspect of the invention. The method comprises the following steps: Bringing at least one retaining rail into a mounted state in which the retaining rail extends vertically along a longitudinal dimension, engaging at least one primary functional module with at least one section of the retaining rail along the longitudinal dimension, wherein the primary functional module is configured at least for separating a shower area and has a shower-side primary functional module side surface, an opposite room-side primary functional module side surface, a primary functional module height in the mounted state that runs parallel to the longitudinal dimension and is smaller than the longitudinal dimension of the retaining rail, and two opposite primary functional module end faces that run orthogonally to the primary functional module height, engaging at least one secondary functional module with at least one section of the retaining rail along the longitudinal dimension.wherein the secondary functional module is configured at least to form a sanitary unit and which has a shower-side secondary functional module side surface, an opposite room-side secondary functional module side surface, a secondary functional module height running parallel to the longitudinal extent in the assembled state, which is less than the longitudinal extent and has two opposing secondary functional module end surfaces extending orthogonally to the longitudinal extent, and brings at least a first primary functional module end surface into contact with a first secondary functional module end surface at least indirectly.

[0045] By providing a corresponding primary function module and a secondary function module, the method according to the fourth aspect of the invention takes advantage of the benefits mentioned at the outset with regard to the first aspect of the invention. Advantages and preferred embodiments according to the first aspect of the invention are also advantages and preferred embodiments according to the fourth aspect of the invention.

[0046] The invention solves the aforementioned problem in a fifth aspect by using a sanitary installation, in particular a sanitary installation according to the first aspect of the invention, to provide a shower area and sanitary furniture according to claim 28. By using such a sanitary installation, the invention takes advantage of the benefits described above in relation to the first aspect of the invention. Advantages and preferred embodiments according to the first aspect of the invention are also advantages and preferred embodiments according to the fifth aspect of the invention, and vice versa.

[0048] Fig. 1 and Fig. 2 Figure 1 shows a first embodiment of a sanitary installation 1 with mounting rails 10, at least one primary function module 20, and at least one secondary function module 30. In this embodiment, the sanitary installation 1 comprises a first mounting rail 10.1 and a second mounting rail 10.2. A first primary function module 20.1 and a second primary function module 20.2 are located between the first mounting rail 10.1 and the second mounting rail 10.2 and engage with the first and second mounting rails 10.1 and 10.2, respectively. The secondary function module 30 is arranged between the first primary function module 20.1 and the second primary function module 20.2 and also engages with the first and second mounting rails 10.1 and 10.2.

[0049] The sanitary installation 1 is shown in an assembled state Z, in which the retaining rails 10.1, 10.2 extend vertically along a longitudinal dimension L. The first retaining rail 10.1 and the second retaining rail 10.2 run parallel to each other.

[0050] The first primary function module 20.1 engages along a first primary section 11.1 of the retaining rails 10.1, 10.2 along the longitudinal extent L. The second primary function module 20.2 engages with a second primary section 11.2 of the retaining rails 10.1, 10.2.
