Description

[0001] The invention relates to a sanitary floor element according to the preamble of patent claim 1 and to a combination of a sanitary floor element with a drain according to the preamble of patent claim 11.

[0002] Sanitary floor elements, such as shower floors, shower trays, or shower bases, have been around for some time. Such sanitary floor elements are typically used in conjunction with shower cubicles and, for this purpose, are placed on the floor of a sanitary area. To use the shower cubicle, one must climb into the usually raised shower cubicle. Previously known shower trays or shower bases have a raised edge, requiring the user to step over the edge, which is difficult or even impossible for people with disabilities. For this reason, options have been created in the past to provide barrier-free access to a shower area.For this purpose, shower floors and / or shower trays were created by tiling the respective screed or subfloor, respectively, flush with the surrounding flooring, allowing easy access to the shower area, even with a wheelchair. Such shower areas typically featured a centrally or slightly offset floor drain, for which a space was provided in the tiled floor in the tiled area of the bathroom or shower.

[0003] DE 20 2012 103906 is an example of the state of the art.

[0004] One problem with these types of bathrooms with tiled shower areas is that the joints between the tiles deteriorate over time, causing cracks to form in the joints, allowing water to seep in. This is particularly problematic in the area of the floor drains, as previous shower areas sloped toward these floor drains, causing water to collect, particularly in the area of these floor drains, and gradually seep into the spaces between the tiles, into the joints, and even underneath the tiles.

[0005] Since the water in these cracks, especially under the tiles, cannot simply be wiped away when cleaning the bathroom or shower, or the shower floor, the water collects in these cracks, causing the joints to become increasingly moist and become breeding grounds for germs, bacteria, mold, and viruses, which enter the cracks either along with the water or by other means. The germs, bacteria, mold, and viruses that accumulate in these cracks and under the tiles pose a long-term problem, as it has been shown that these germs can be stirred up to 1 m high when showering and can thus cause infections and diseases.This is particularly serious when it affects people who are already handicapped or sick, for example those in a wheelchair, whose faces are at the level of the stirred-up germs and who may even inhale them.

[0006] Cleaning the cracks in the joints and the areas beneath the joints is not possible because these areas are not easily accessible. However, merely superficial cleaning of the tiles has not proven to be sustainable, as this prevents direct access to the breeding grounds between the tiles, between the tiles and the tile adhesive, and between the tiles and the subfloor, such as a precast concrete floor and / or screed. Furthermore, cleaning agents designed to effectively fix such germs are often very aggressive and can attack the building material, the tiles, the tile adhesive, and the grout, which may contribute to even faster crack formation.

[0007] For this reason, previous measures to eliminate such contamination generally involved structural measures, such as opening up the floor, removing the contaminated and damp areas, and rebuilding the shower floor. Another option for eliminating such contamination was, for example, removing the old bathroom cubicles and creating completely new ones. However, like the previously described measure, this is associated with very high costs. However, since the elimination of such contamination by germs, bacteria, mold, and viruses is unavoidable for hygiene reasons, structural measures were always unavoidable.The invention is based on the object of offering a solution to the problem described above, which opens up an alternative possibility in a simple and cost-effective manner by which the contamination of tiled shower floors described above is avoided, while the respective shower cubicle can also be used easily and without problems by disabled people.

[0008] This object is achieved by a combination of a sanitary floor element with a drain according to patent claim 1.

[0009] In particular, this object is achieved by a sanitary floor element, namely in particular a shower floor, a shower tray or a shower base, with a tub-, bowl- or cup-shaped sanitary floor body which is open at the top in the installed state for installation on a wall of a sanitary room, wherein the sanitary floor body has a completely closed floor surface, namely shower floor, shower tray or shower base surface, and at least one, in particular beak-shaped, projection serving as a floor surface drain which extends away from the floor surface, wherein the projection has an upper side and a lower side and wherein the upper side of the projection adjoins the floor surface, in particular seamlessly, or is designed as part or continuation of the floor surface.

[0010] An essential point of the invention is that the sanitary floor element according to the invention has a sanitary floor body with a completely closed floor surface which, according to the invention, is explicitly not composed of individual segments, such as tiles, but is formed integrally and continuously. A further essential point of the invention is that an overhang serving as a floor surface drain adjoins the floor surface of the sanitary floor body, extends away from the floor surface and into which the floor surface of the sanitary floor body according to the invention merges seamlessly. According to the invention, the overhang is formed integrally with the sanitary floor body and projects beyond it, or rather beyond the floor surface of the sanitary floor body, i.e. beyond a wall-side edge of the sanitary floor body.

[0011] If the sanitary floor body is arranged adjacent to a wall during installation of the sanitary floor element according to the invention, the projection projects into an opening provided in the wall if the sanitary floor element according to the invention is installed directly against the wall.

[0012] In other words, the projection in the form of a protrusion projects beyond a wall of the sanitary room adjacent to one or both sides of the projection into the wall of the sanitary room and thus beyond a floor surface of the sanitary floor element adjacent to the wall of the sanitary room.

[0013] The overhang therefore not only represents a breakthrough through any surge or edge strip which, according to a preferred embodiment, limits the sanitary floor element on the wall side and rests against the wall of the sanitary room as a side wall element in order to prevent water from flowing to the wall of the sanitary room at the side of the overhang, but also a type of ramp which projects beyond the floor surface of the sanitary floor element arranged in the surface of the sanitary room up to a drain pot of a wall drain.

[0014] In this way, it is possible that, when the sanitary floor element is in use, water located on the floor surface of the sanitary floor element is disposed of in a waterfall-like manner via a distal drainage edge of the overhang, or rather the lateral floor surface drain, located at the level of the sanitary floor element, into the opening provided in the wall and there via the provided wall drain.

[0015] According to a preferred embodiment of the invention, the overhang extends to approximately the middle of the drain pot of the wall drain, so that the draining water can flow unhindered, directly and immediately into the drain pot and thus into the wall drain.

[0016] The projection of the sanitary floor element according to the invention therefore has no drainage obstruction at its distal end, for example in the form of a protruding edge or the like, but on the contrary can have a gradient that increases in the direction of the drainage edge or drain pot.

[0017] This ensures that water that reaches the floor surface of the sanitary floor element during showering flows directly over the overhang serving as a floor surface drain into the wall drain located in the wall opening, without the water having to flow over any joint, especially over a tile joint. The previously existing risk of water penetrating joints, tile gaps, and / or under tiles in the shower area is thus no longer present thanks to the sanitary floor element according to the invention.

[0018] According to one embodiment of the invention, the floor surface has at least one gradient in the direction of the overhang, through which fluid, in particular water, located on the floor surface flows in the direction of the overhang.

[0019] This ensures that no water remains on the floor surface of the sanitary floor unit, but drains safely and reliably via the overhang and the wall drain. The invention thus virtually eliminates the formation or growth of germs on the floor surface of the sanitary floor unit, as the floor surface of the sanitary floor unit dries very quickly after the water drains away, effectively preventing contamination of the floor surface of the sanitary floor unit with germs, bacteria, mold, and viruses.

[0020] Depending on the shape of the sanitary floor element according to the invention, the overhang can be arranged centrally or laterally offset on a wall edge of the sanitary floor body facing the wall. Accordingly, the floor surface can have at least one slope that inclines toward a projection arranged, for example, laterally on the wall edge. However, if the overhang is arranged centrally on the wall edge of the sanitary floor body, the floor surface of the sanitary floor body can also have a slope on several sides, which ensures that draining water always flows in the direction of the overhang.

[0021] In this context, it should be noted that the sanitary floor element according to the invention can, if desired, also have a plurality of projections that serve as drains. For example, a sanitary floor element according to the invention can also have two, three, or more projections arranged next to one another along an edge of the sanitary floor element. If the sanitary floor element is arranged in a corner of a room, for example, these multiple projections can also be arranged on the edge of the sanitary floor element associated with a wall of the room, where they can each serve as a drain into a wall drainage device.

[0022] To ensure that the draining water flows exclusively through the overhang into the wall drain, the invention defines that at least the overhang is laterally limited by two side walls extending upwards on both sides. These side walls, which function as splash guards, laterally limit the overhang and guide the draining water safely through the drainage channel defined by the overhang and side walls into the wall drain.

[0023] According to a further embodiment of the invention, at least one side wall or surge strip delimiting the overhang can also extend along a lateral wall edge of the sanitary floor body. Such an embodiment is particularly advantageous because it reliably ensures that draining water does not penetrate between the sanitary floor element according to the invention and the wall, but remains exclusively on the floor surface of the sanitary floor body and is guided through the side wall in any case toward the overhang, where it drains exclusively via the overhang into the drainage channel.

[0024] According to a further advantageous embodiment of the invention, a transition from the base surface of the sanitary floor body to an adjoining wall, in particular a side wall, is designed in the form of a groove, in particular a concave groove. The resulting curve between the base surface of the sanitary floor body and the laterally adjoining wall is particularly easy to clean; moreover, runoff water flows away more easily and reliably along this curve of the groove than from a right-angled intersection of the base surface and the wall.

[0025] According to the invention, the floor surface of the sanitary floor body has at least one, preferably two or three, barrier-free edge(s) laterally delimiting the floor surface, which edge(s) enable / enable obstacle-free, driveable and walkable, in particular flush-mounted, use of the sanitary floor element and are in particular designed without an overflow edge and / or without walls.

[0026] In this way, the sanitary floor element according to the invention can be integrated flatly and flush into the floor surface of a bathroom or wet room, so that the shower area of a bathroom equipped with the sanitary floor element according to the invention can also be easily accessed by a wheelchair. Furthermore, since the sanitary floor element according to the invention does not have an overflow edge, no steps need to be climbed to access the sanitary floor element.

[0027] In this way, the sanitary floor element according to the invention can be integrated into a bathroom floor in an extremely elegant and attractive manner, without disturbing edges or steps disturbing the aesthetics of the bathroom floor.

[0028] According to a further advantageous embodiment of the invention, the overhang has a drip device on its underside, in particular a drip strip, a drip edge, or a drip groove. This drip device ensures in a simple and advantageous manner that draining water does not flow from the top side of the overhang over its wall-drainage edge to the underside of the overhang and collect and / or spread there.The drip device, which is designed as a drip strip, drip edge or drip groove, which extends essentially parallel to the wall drain-side edge on the underside of the overhang, ensures that any drops that actually reach the wall drain-side edge of the overhang on its underside drip safely into the collecting container of the wall drain and in this way the underside of the overhang is safely drained and dries quickly and safely after the drops have dripped off.

[0029] According to one embodiment of the invention, the projection and / or the sanitary floor element has a preferably permanently elastic sealing compound, for example in the form of a first seal, adjacent to the projection on its underside, wherein the sealing compound and / or seal comprises, for example, butyl rubber.

[0030] Such an embodiment of the sanitary floor element according to the invention is particularly well suited to preventing water from flowing under the sanitary floor element according to the invention and penetrating a floor or screed of a sanitary room, in particular in the event of a possible backflow of draining water. According to a particularly preferred embodiment of the invention, the first seal used according to the invention is designed to be permanently elastic, which means that the first seal used according to the invention adapts to the respective dimensions of a sealing joint due to its elasticity. This is particularly useful if the screed of a sanitary room, for example, settles somewhat over time, i.e. sinks, as a result of which the space between the sanitary floor element and the floor or screed of the sanitary room, or between the overhang and the floor or screed of the sanitary room, increases somewhat.In this case, the seal, which was installed in a slightly compressed state, adapts to the then enlarged sealing joint by slightly relaxing the seal. In the same way, the seal used according to the invention also adapts to a shrinking sealing joint if, for example, the sanitary floor element according to the invention sinks slightly, so that the distance between the sanitary floor element and the floor or screed is reduced.

[0031] The first seal used according to the invention is arranged either directly on an underside of the projection or directly adjacent to the projection on an underside of the sanitary floor element itself, so that in any case penetration of water under the sanitary floor element into the floor and / or screed is also reliably prevented.

[0032] Butyl rubber, for example, has proven to be particularly advantageous as a material for this permanently elastic seal, as this material reliably retains its elasticity over a very long period of time.

[0033] According to a further advantageous embodiment of the invention, this first seal can only be applied to the underside of the overhang or sanitary floor element during installation of the sanitary floor element according to the invention. According to an alternative embodiment of the invention, the sealing material used for this seal can also be applied in advance, i.e., ex works, to the underside of the overhang or sanitary floor element. In this case, a spacer is arranged on at least one side of the sealing material, which spacer must be removed before installation of the sanitary floor element, in order to ensure that the sealing material is compressed during storage of the sanitary floor element or during its transport.

[0034] According to the invention, the sanitary floor element is preferably made of a homogeneous material, such as a pourable synthetic resin, especially one filled with at least one mineral. A cured mineral-filled acrylate, marketed under the trademark "Quaryl," has proven particularly advantageous.

[0035] On the one hand, this material is very easy to process, stable, robust, has a non-slip surface and is also easy to clean and saw, so that the sanitary floor element according to the invention can be easily adapted to the respective local conditions of a bathroom.

[0036] Furthermore, the sanitary floor element according to the invention is formed in one piece.

[0037] Furthermore, the object of the invention is also achieved by a combination of a sanitary floor element according to the above embodiments with a wall drain device, wherein the wall drain device comprises a wall drain housing which can be arranged in a wall or wall opening and can be connected to a wastewater line and has at least one inlet opening, and wherein the projection of the sanitary floor element, optionally with at least one side wall laterally delimiting the projection, projects into the at least one inlet opening of the wall drain housing.

[0038] Such a combination of a sanitary floor element according to the invention with a wall drain device is particularly advantageous since in this way a safe drainage of water which is located on the surface of the sanitary floor element, for example a shower surface, when the sanitary floor element according to the invention is used is ensured, wherein in this case the water is introduced in a defined manner from the surface of the sanitary floor element via the overhang into the inlet opening of the wall drain housing and fed to a wastewater pipe.

[0039] For this purpose, the overflow extends into the inlet opening of the wall drain housing, whereby the side walls, or baffles, laterally delimiting the overflow can either reach up to the inlet of the inlet opening of the wall drain housing or, alternatively, extend into the inlet opening. It should be noted that the latter embodiment is preferred according to the invention, since this also ensures that all of the draining water is directed via the overflow into the inlet opening of the wall drain housing and fed into a wastewater line.

[0040] According to a further embodiment of the invention, the wall drain device has at least one sealing fleece, in particular in the form of a floor sealing fleece and / or wall sealing fleece, which is connected on the one hand to the wall drain housing and on the other hand serves to create a seal of water-bearing areas of the wall drain device with respect to an adjacent floor, screed or similar supporting floor of the sanitary floor element and / or with respect to a wall adjacent to the wall drain device.

[0041] Such a sealing fleece can be advantageously used to create and maintain a tight yet flexible connection between the wall drain device according to the invention and a floating screed. For this purpose, the sealing fleece is firmly and tightly connected to the wall drain device on the one hand and is connected, in particular flatly, to the screed and / or a wall adjacent to the wall drain device on the other. Such a connection of the sealing fleece to the screed or a wall is preferably achieved by precisely adapting the shape of the sealing fleece to the surface to be sealed and attaching it to this surface with a sealing compound. For this purpose, a sealing slurry or another connection ensuring a seal, such as a sealing adhesive, can be used.A key advantage of using a sealing fleece is that it can be perfectly adapted to even uneven subfloors. Furthermore, the sealing fleece can be cut to size, allowing it to be adapted to any complex subfloor geometry. According to the invention, the same also applies to attaching the sealing fleece to a wall adjacent to the drain device.

[0042] The sealing fleece can be designed as a floor sealing fleece or as a wall sealing fleece and can be attached accordingly only to the floor of the wall drain device or only to an upper and, if applicable, the side edges of the wall drain device. Likewise, the sealing fleece can be constructed in several parts or in one piece, although according to the invention, a one-piece design of the sealing fleece is particularly preferred, as this avoids any seams that could cause sealing problems. An arrangement of the sealing fleece around the inlet opening, or rather the inlet opening, of the wall drain housing is particularly preferred.

[0043] Furthermore, the wall drain device according to the invention can further comprise an odor trap and / or a hair strainer, each of which is accessible via the inlet opening of the wall drain housing and, if necessary, removable. For this purpose, the odor trap and / or the hair strainer are preferably arranged in a housing that is removably inserted into the wall drain housing. Alternatively, the housing for the odor trap and / or the hair strainer can also be formed integrally with the wall drain housing.

[0044] Furthermore, it should be noted that, particularly in the event that the sanitary floor element according to the invention has more than one projection serving as a drain, the wall drain device used according to the invention can also have a plurality of inlet or inlet openings, wherein a respective projection then projects into a respective inlet opening. In this case, an odor trap and / or hair strainer can be assigned to each individual inlet opening; however, it is also conceivable that such an odor trap and / or such a hair strainer is / are arranged in a common collecting drain line. Alternatively, a separate wall drain device can also be assigned to each respective projection. This can be advantageous in particular with large-sized sanitary floor elements.Furthermore, it should be noted that according to the invention, at least one second sealing device, in particular in the form of a sealing strip and / or a sealing compound, is provided between the sanitary floor element and an adjacent wall, in particular between the sanitary floor element and the wall drain device, and is arranged there when the sanitary floor element and the wall drain device are in use.

[0045] In this way, the respective wall-side edges of the sanitary floor element according to the invention, or the respective baffles, can be additionally sealed both against the floor or screed of a sanitary room and against the walls adjacent to the sanitary floor element. With the help of the sealing device used, any unevenness can also be compensated for, thus reliably preventing water from penetrating between the sanitary floor element according to the invention and adjacent wall or floor areas. Thus, such a second sealing device serves as a supplementary seal to the aforementioned sealing fleece and can be used when such an additional seal is expedient, for example due to structural conditions.

[0046] The invention can thus be summarized as follows.

[0047] By combining a wall drain with a shower surface, whose draining water is guided or flows directly and precisely into the wall drain via the overhang, it is ensured that the water is transported safely and with minimal splashing from the surface area of the sanitary floor element into the wall drain. This represents a significant advantage, as avoiding splashing also reliably prevents any germs in the shower water from being stirred up. Any back splashing of water during drainage is also effectively reduced. Thus, the inventive solution represents a low-aerosol solution that minimizes the risk of infection.Furthermore, the solution according to the invention requires significantly fewer parts than previous sanitary floor elements, such as shower trays or the like, which significantly reduces the risk of possible assembly errors during installation of the sanitary floor element according to the invention. Furthermore, the shower surface according to the invention is self-supporting and can be easily adapted and cut to the required sizes using Quaryl or another synthetic resin, particularly mineral-filled synthetic resin.

[0048] A further advantage of the sanitary floor element according to the invention is that, compared to previous sanitary floor elements, fewer, or even no, joints are required, apart from the sealing joint to the surrounding bathroom floor, which offers significantly fewer opportunities for soiling and adhesion.

[0049] Furthermore, the sanitary floor element according to the invention has a permanently closed, smooth, and scratch-resistant surface, which ensures easy drainage and removal of water and any contaminants. Such a surface can be achieved, for example, through the particularly preferred use of Quaryl as the material for the sanitary floor element according to the invention. Open pores and joint cracks, such as those encountered in the prior art and which absorbed dirt, germs, and bacteria and provided them with a breeding ground, are no longer present in the solution according to the invention, i.e., the sanitary floor element according to the invention.

[0050] The possibility of cutting the sanitary floor element according to the invention also ensures good adaptation on site if adjustments to the existing structure are necessary.

[0051] The minimal joint design of the system structure according to the invention also ensures less standing moisture and thus less breeding ground for bacteria and generally lower room humidity, which further improves hygienic conditions.

[0052] The slip resistance of the sanitary floor element according to the invention, especially when it is made of Quaryl or another mineral-filled synthetic resin, represents a further significant advantage of the solution according to the invention.

[0053] Since the sanitary floor element according to the invention is a system that simultaneously represents a sanitary floor body, a floor surface of the sanitary floor element and a drain of the sanitary floor element in one part, this system is easier to install than previous systems and offers a lower probability of errors than previous multi-part solutions.

[0054] A further significant advantage of the sanitary floor element according to the invention arises from the fact that the shower surface is equipped with an overhang and a drip edge, with the overhang extending into an opening of a wall drain. This reduces the splashback of contaminated water standing in the drain. The solution according to the invention thus offers high ease of cleaning and thus low ongoing maintenance costs. The higher scratch resistance compared to other materials resulting from the use of Quaryl advantageously results in a longer service life as well as greater chemical resistance and greater slip resistance, which reduces the risk of falls and thus any liability risks, for example in public spaces.

[0055] Furthermore, in times of pandemics and widespread infections, low-aerosol solutions such as those provided by the sanitary floor element according to the invention are extremely advantageous. This is particularly true for bathrooms in healthcare facilities that require hygienic cleanliness, but also for many areas of the hotel industry. Good accessibility of the drain also minimizes further cleaning and service costs.

[0056] In this context, it should be noted that the wall drain can be provided with a cover, for example a stainless steel cover, which can be held magnetically, as well as with a hair strainer and an odor trap.

[0057] Using Quaryl as a material for the sanitary floor element according to the invention also provides a high-quality appearance, offers the advantages of a scratch-resistant material, as well as superior resistance to cleaning agents and high slip resistance. Despite its slip resistance, the material is still easy to clean, offers a pleasant feel, is sound-absorbing, and feels warm to the feet when walked on. Another important criterion for using Quaryl as a material for the sanitary floor element according to the invention is that Quaryl is a particularly load-bearing material, especially for low construction heights, which is particularly important for modernization or new construction and also represents an advantageous factor in terms of lower costs. Furthermore, the material can be cut to size and even adapted on site, which is a key advantage, especially for modernization projects.Furthermore, Quaryl can be sealed particularly well against surrounding surfaces; repairs to the material of the sanitary floor element are then also possible.

[0058] Furthermore, a combination of the sanitary floor element according to the invention with a wall drain device, in particular a wall drain housing, can ensure safe and leak-free drainage of water. For this purpose, a projection of the sanitary floor element serving as a drain extends directly into the wall drain housing, so that draining water can be safely fed into a sewer line without the risk of water possibly penetrating between the sanitary floor element and adjacent masonry.

[0059] Further embodiments of the invention emerge from the subclaims.

[0060] The invention is described below using an exemplary embodiment, which is explained in more detail with reference to the figures. Fig. 1 shows a schematic representation of a sanitary floor element according to the invention in accordance with an embodiment of the invention in a perspective view; Fig. 2 shows a schematic representation of a sanitary floor element according to the invention in accordance with an embodiment of the invention in a further perspective view; Fig. 3 shows an enlarged detail of the embodiment according to Fig. 2 ; Fig. 4 a schematic representation of a sanitary floor element according to the invention according to an embodiment of the invention in plan view; Fig. 5 a schematic representation of a sanitary floor element according to the invention according to Fig. 4 along the section line AA; Fig. 6 a schematic representation of a combination of sanitary floor element and wall drain according to the invention; Fig. 7 a schematic representation of a sanitary floor element according to the invention, which is inserted into an inlet opening of a wall drain housing used according to the invention; Fig. 8 a schematic representation of the sanitary floor element according to the invention according to Fig. 7 before insertion into the inlet opening of the wall drain housing used according to the invention; and Fig. 9 a schematic representation corresponding Fig. 8 using a second sealing device.

[0061] In the following description, the same reference numbers are used for identical and equivalent parts.

[0062] The Fig. 1 und Fig. 2 Both show a schematic representation of a sanitary floor element 10 according to the invention in accordance with an embodiment of the invention in a perspective view. The sanitary floor element 10 has a sanitary floor body 20 with a floor surface 30, which merges seamlessly into a projection 40. The projection 40 serves as a drain from the floor surface 30 of the sanitary floor body. Furthermore, the projection 40 is delimited on both sides by respective side walls 70, which continue along a wall edge 80 of the sanitary floor body 20. The sanitary floor element 10 according to the invention further has an upper side 50, which is formed by the floor surface 30 of the sanitary floor body 20. In addition, a lower side 60 is arranged opposite the upper side 50 of the sanitary floor body 20. On the lower side 60 of the sanitary floor body, which simultaneously represents the lower side 60 of the projection 40, a drip device 110 is arranged, which is particularly in Fig. 3 can be clearly seen. The drip device 110 is designed in the form of a drip groove, which ensures that any water drops located on the underside 60 of the projection drip safely into the wall drain.

[0063] Furthermore, in the Fig. 1 und Fig. 2 It can be seen that the sanitary floor element according to the invention has barrier-free edges 100 on three sides. These three barrier-free edges 100 are the remaining edges of the sanitary floor body 20, which do not have an overhang 40, but can be integrated flush into the surrounding bathroom floor.

[0064] Fig. 4 shows a schematic representation of a sanitary floor element 10 according to the invention according to an embodiment of the invention in plan view. The sanitary floor element 10 shown is essentially flat and square and has, as in the Fig. 5 shown sectional view along section line AA, has slopes 120 arranged on the sides, which ensure that runoff water flows towards the center in the direction of overhang 40.

[0065] With regard to the respective preferred dimensions of the sanitary floor element according to the invention, it should be noted that it can, for example, have a total height of 30 mm at its highest side facing away from the projection 40, while the projection 40 itself can have a material thickness of 15 mm. The edges or walls delimiting the projection can, for example, have a material thickness of 10 mm.

[0066] Fig. 6 shows an exemplary schematic representation of a projection 40 according to the invention, or rather a shower surface tongue, which projects into a preferably precisely fitting inlet opening 240 of the wall drain housing 200. Sealing fleeces 170, 180 seal the wall drain to the wall 190 and the floor 150 of a sanitary room. The shower surface tongue 40 projects into the wall drain housing 200 with lateral splash bars 70 and a groove 110 for creating a drip edge on the underside of the shower surface 130. Furthermore, an optional first seal 160 is arranged between the projection 40 and the floor sealing fleece 170, which can preferably consist of a sealing, permanently elastic adhesive and / or a sealing compound and / or a prefabricated seal or alternatively, but less preferably, of mortar, which preferably has sealing properties.In the lower area of the wall drain housing 200 there is an installation space 220, for example in the form of a housing for an odor trap and / or a hair strainer, which can be designed as one piece with the wall drain housing 200.

[0067] Fig. 7 shows an exemplary schematic perspective representation of a shower surface tongue 40 that projects into the wall drain housing 200 used according to the invention. A wall sealing fleece 180 securely seals the wall drain all the way around to the wall 190, and a floor sealing fleece 170 securely seals it to the floor 150 of the sanitary room. The shower surface tongue, i.e., the overhang 40, projects into the wall drain housing 200 with lateral walls in the form of surge bars 70. The surge bars 70 guide the water directly into the wall drain housing 200, so that the draining water does not have to pass through any previously conventionally used seals that would require maintenance or could become permeable.

[0068] According to the invention, the illustrated lateral shower surface edge 140 can also be omitted, thus making the shower surface 130 even flatter and more accessible. Such a flat design of the sanitary floor element 10 according to the invention is particularly advantageous in the case of modernization and with a flat screed structure.

[0069] Fig. 8 shows an exemplary schematic perspective view of a shower surface tongue 40, which is located before being inserted into the wall drain housing 200. The one-piece sealing fleece 170, 180 is attached circumferentially around the wall drain towards the wall 190 and the floor 150 of the sanitary room.

[0070] Fig. 9shows a schematic view of additional sealing areas for second sealing devices 230, which can be mounted between the wall 190 and the frontal splash bars 70 of the shower surface 130, but can also be arranged in the floor area 150 below the shower surface 130. These second sealing devices 230 can be designed to be permanently elastic and prevent water from flowing back under the shower surface 130, even if the wall drain is blocked.

[0071] The second sealing devices 230 between the floor 150 and the shower surface 130 can also be applied more voluminously, so that the shower surface 130 can be laid in a mortar bed like tiles.

[0072] The second sealing devices 230 can generally comprise the following variants of seals: Optional seal(s) between the wall and the frontal splash bars of the shower surface, which can optionally be factory-attached to the shower surface from the outside and, if necessary, can also be circumferential.
