Description

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.

Sanitary floor elements such as shower floors, shower trays or shower trays have been known for some time. Sanitary floor elements of this type are generally used in connection with shower stalls and are placed on the floor of a sanitary area for this purpose. To use the shower stalls, you have to climb into the generally elevated shower stall. Previously known shower trays or shower trays have a raised edge that requires climbing over the edge, which is difficult or impossible for disabled people, for example. For this reason, possibilities were created in the past to get into a shower area barrier-free. For this purpose, shower floors and/or shower trays were produced by tiling the respective screed or the respective subsurface, which were flush with the surrounding floor covering, so that one could easily get into the shower area, even with a wheelchair, for example. Such shower areas generally had a floor drain offset in the middle or slightly to the side, for which space was left in the tiled floor in the tiled area of the bathroom or shower.

A problem with such bathrooms that have tiled shower areas is that joints between the respective tiles deteriorate over time, causing cracks in the joints to form into which water can penetrate. This is particularly problematic in the area of the respective floor drains, since previous shower areas had an incline or slope in the direction of these floor drains, so that water collected in particular in the area of these floor drains and gradually in the spaces between the tiles and in the joints as well as seeping under the tiles.

Since the water in these cracks, especially under the tiles, cannot simply be wiped away when cleaning the bathroom or the shower or the shower floor, the water collects in these cracks, which means that the joints become more and more wet and become soggy Breeding grounds for germs, bacteria, mold and viruses that get into the joint cracks either together with the water or in some other way. The germs, bacteria, mold and viruses that accumulate in this way in the joint cracks and under the tiles represent a lasting problem, as it has been shown that these germs are whirled up to a height of 1 m when showering and thus cause infections and can cause disease. This is particularly serious when it affects people who are already handicapped or ill, for example, who are in a wheelchair and thus have their face level with the germs that are thrown up and may even inhale them as a result.

It is not possible to clean the cracks in the joints or the areas under the joints, as these areas are not reasonably accessible. On the other hand, only superficial cleaning of the tiles has not proven to be sustainable, as this means that the hotbeds between the tiles and the tiles and the tile adhesive as well as between the tiles and the unfinished floor, for example a prefabricated concrete cell floor and/or the screed, cannot be reached directly. In addition, cleaning agents that are generally suitable for fixing such germs to a certain extent are often very aggressive and can attack the building material as well as the tiles, the tile adhesive and the joint material, which under certain circumstances can contribute to even more rapid crack formation. For this reason, previous measures to eliminate such contamination usually consisted of structural measures that required, for example, opening the floor, removing the contaminated and damp areas and rebuilding the shower floor. A further possibility to eliminate such contaminations was, for example, the removal of the old ones and the creation of completely new bath cells, which, however, like the measure described above, is associated with very high costs. However, since the elimination of such contamination by germs, bacteria, mold and viruses is unavoidable for reasons of hygiene, structural measures were always unavoidable.

The invention is based on the object of offering a solution to the above-described problem that opens up an alternative possibility in a simple and inexpensive 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 can be.

This object is achieved by a sanitary floor element according to patent claim 1 and by a combination of a sanitary floor element with a drain according to patent claim 11 .

In particular, this object is achieved by a sanitary floor element, namely in particular a shower floor, a shower tray or a shower tray, with a trough-shaped, bowl-shaped or cup-shaped sanitary floor body which is open at the top when installed, for installation on a wall of a sanitary room, the sanitary floor body having a completely closed floor surface , namely a shower floor, shower tray or shower tray surface, and has at least one overhang, in particular a beak-shaped one, serving as a floor surface drain, which extends away from the floor surface, the overhang having an upper side and an underside and the upper side of the overhang extending, in particular without a transition, connects to the bottom surface or is designed as part or continuation of the bottom surface.

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 individual segments, such as tiles, is composed, but is formed in one piece and continuously. Another essential point of the invention is that the bottom surface of the sanitary floor body is adjoined by a projection serving as a floor surface drain, which 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 in one piece with the sanitary floor body and protrudes beyond this or over the floor surface of the sanitary floor body, ie beyond a wall-side edge of the sanitary floor body.

If the sanitary floor body is arranged adjacent to a wall as part of an installation of the sanitary floor element according to the invention, the overhang protrudes into an opening provided in the wall when the sanitary floor element according to the invention is installed directly adjacent to the wall.

In other words, the overhang protrudes in the form of a projection beyond a wall of the sanitary room adjoining one side or both sides of the projection into the wall of the sanitary room and thus beyond a floor area of the sanitary floor element adjoining the wall of the sanitary room.

The overhang thus not only represents an opening through any surge or edge strip, which according to a preferred embodiment delimits the sanitary floor element on the wall side and as a side wall element rests against the wall of the sanitary room in order to prevent water from laterally overhanging the wall of the sanitary room flows, but also a kind of rampart that protrudes beyond the floor surface of the sanitary floor element arranged in the surface of the sanitary room to a drain pan of a wall drain.

In this way, it is possible that when using the sanitary floor element on the floor surface of the sanitary floor element, water located on the floor surface of the sanitary floor element via a distal edge of the overhang, which is at the level of the sanitary floor element, or the side floor surface drain, like a waterfall, into the opening provided in the wall and disposed of there via the wall drain provided. According to a preferred embodiment of the invention, the overhang protrudes to about the middle of the drain pan of the wall drain, so that the water running off can pour unhindered, directly and immediately into the drain pan and thus into the wall drain.

The protruding part of the sanitary floor element according to the invention therefore has no flow obstruction at its distal end, for example in the form of a protruding edge or the like, but on the contrary can have an increasing gradient in the direction of the drainage edge or drainage pot.

This ensures that water that gets onto the floor surface of the sanitary floor body when showering flows directly via the overhang serving as the floor surface drain into the wall drain arranged in the wall opening, without the water having to flow over any joint, in particular over a tile joint. The previously existing risk of water penetrating into joints, spaces between tiles and/or under tiles in the shower area is therefore no longer given by the sanitary floor element according to the invention.

According to one embodiment of the invention, the bottom surface has at least one gradient in the direction of the projection, through which fluid located on the bottom surface, in particular water, flows in the direction of the projection.

In this way it is ensured that no water remains on the floor surface of the sanitary floor body, but rather drains away safely and reliably via the overhang and the wall drain. A formation of germs or growth of germs on the floor surface of the sanitary floor body is thus practically ruled out according to the invention, since the floor surface of the sanitary floor body dries very quickly after the water has run off, which effectively prevents contamination of the floor surface of the sanitary floor body with germs, bacteria, mold and viruses .

Depending on the shape of the sanitary floor element according to the invention, the overhang can be arranged centrally or also laterally offset on a wall edge of the sanitary floor body facing the wall. Accordingly, the bottom surface can have at least one gradient, which inclines in the direction of an overhang arranged, for example, laterally on the wall edge. However, if the overhang is arranged centrally on the wall edge of the sanitary floor body, it can the bottom surface of the sanitary floor body also has a gradient on several sides, which ensures that water running off flows in the direction of the overhang.

In this context it should be pointed out that the sanitary floor element according to the invention can also have several overhangs, which serve as a drain, if desired. For example, a sanitary floor element according to the invention can also have two, three or more overhangs, which are arranged next to one another along an edge of the sanitary floor element. If the sanitary floor element is arranged, for example, in a corner of a room, these several projections can also be arranged on the respective edge of the sanitary floor element assigned to a wall of the room and serve there as a drain into a wall drain device.

In order to ensure according to the invention that the outflowing water flows exclusively via the overhang into the wall drain, according to the invention at least the overhang is delimited laterally by two side walls extending upwards on both sides. These side walls, which serve functionally as surge strips and can be described as laterally delimiting the overhang and safely guide the water running off through the drainage channel defined by the overhang and side walls into the wall drain.

According to a further embodiment of the invention, at least one side wall delimiting the overhang, or surge strip, can also continue along a lateral wall edge of the sanitary floor body. Such an embodiment is particularly advantageous because it ensures that water running off does not penetrate between the sanitary floor element according to the invention and the wall, but rather remains exclusively on the floor surface of the sanitary floor body and is guided through the side wall in the direction of the overhang and exclusively over there the supernatant runs off into the drainage channel.

According to a further advantageous embodiment of the invention, a transition from the bottom surface of the sanitary floor body to an adjoining wall, in particular a side wall, is designed in the form of a channel, in particular a channel. A resulting curve between the bottom surface of the sanitary floor body and the side adjoining wall is particularly easy to clean; in addition, water runs off more easily and reliably along this curve of the throat than from a right-angled collision of floor surface and wall.

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 enable/enable an obstacle-free use of the sanitary floor element that can be driven on and walked on, in particular flush with the surface, and in particular is designed without an overflow edge and/or without walls is/are.

In this way, the sanitary floor element according to the invention can be integrated flat 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 accessed with a wheelchair without any problems. Since the sanitary floor element according to the invention also has no overflow edge, there is also no need to climb a step to step onto the sanitary floor element.

In this way, the sanitary floor element according to the invention can be integrated into a bathroom floor in an extremely shapely and appealing manner, without annoying edges or steps disturbing the aesthetics of the bathroom floor.

According to a further advantageous embodiment of the invention, the overhang has a drip device on its underside, in particular a drip ledge, a drip edge or a drip groove. This draining device ensures in a simple and advantageous manner that water running off does not flow from an upper side of the overhang via its edge on the wall outlet side to the underside of the overhang and collect and/or distribute there. The drip device, which is designed as a drip strip, drip edge or drip groove, which extends essentially parallel to the edge on the wall drain side on the underside of the overhang, ensures that any drops that actually get over the edge of the overhang on the wall drain side on its underside drip safely into the collection container of the wall drain and in this way the underside of the

Surplus is effectively drained and dries quickly and safely after any drops have dripped off.

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

Such an embodiment of the sanitary floor element according to the invention is particularly well suited to prevent water from flowing under the sanitary floor element according to the invention and penetrating into a floor or screed of a sanitary room, particularly in the event of a possible backwater 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 extremely useful, for example, when the screed in a sanitary room settles a little over time, i. H. decreases, whereby the space between the sanitary floor element and the floor or screed of the sanitary room, or between the supernatant 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 relaxing the seal somewhat. In the same way, the seal used according to the invention also adapts to a narrowing sealing joint if, for example, the sanitary floor element according to the invention sinks somewhat, so that a distance between the sanitary floor element and the floor or screed is reduced.

The first seal used according to the invention is arranged either directly on an underside of the overhang or immediately adjacent to the overhang 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 likewise reliably avoided.

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

According to a further advantageous embodiment of the invention, this first seal can only be attached to the underside of the overhang or sanitary floor element during the 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. H. ex works, on the underside of the overhang or sanitary floor element, in which case a spacer to be removed before installing the sanitary floor element is arranged at least on one side of the sealing material in order to ensure that the sealing material during storage of the sanitary floor element or during Transport is pressed.

According to the invention, the sanitary floor element is preferably made of a homogeneous material, such as a castable synthetic resin, in particular filled with at least one mineral. A hardened, mineral-filled acrylate sold under the trademark “Quaryl” has proven particularly advantageous here.

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.

Otherwise, the sanitary floor element according to the invention is designed in one piece.

Furthermore, the object of the invention is also achieved by a combination of a sanitary floor element according to the above statements with a wall drain device, wherein the wall drain device comprises a wall drain housing that can be arranged in a wall or wall opening and can be connected to a waste water line and has at least one inlet opening, and the overhang of the sanitary floor element, optionally with at least one side wall delimiting the overhang laterally, into which at least one inlet opening of the wall drain housing protrudes.

Such a combination of a sanitary floor element according to the invention with a wall drainage device is particularly advantageous, since in this way a reliable drainage of water that is on the surface of the sanitary floor element, for example a shower surface, when using the sanitary floor element according to the invention is guaranteed, with the water in in this case is introduced from the surface of the sanitary floor element via the overhang defined into the inlet opening of the wall drain housing and fed to a waste water line.

For this purpose, the overflow extends into the inlet opening of the wall drain housing, with the side walls or baffles laterally delimiting the overhang reaching either up to the inlet of the inlet opening of the wall drain housing or alternatively extending 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 water flowing off is routed via the overhang into the inlet opening of the wall drain housing and fed to a waste water line.

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 to produce a seal of water-conducting areas of the wall drain device with respect to an adjacent floor, screed or the like supporting floor of the sanitary floor element and/or a wall adjacent to the wall drain device.

Such a sealing fleece can be used in an advantageous manner to create and maintain a tight and at the same time flexible connection of the wall drain device according to the invention with a floating screed. For this purpose, the sealing fleece is firmly and tightly connected to the wall drain device on the one hand and connected to the screed and/or a wall adjoining the wall drain device on the other side, in particular over a large area. Such a connection of the sealing fleece with the screed or a wall is preferably carried out in that the sealing fleece in terms of its shape exactly the surface to be sealed is adapted and attached to this surface with a sealing compound. For this purpose, for example, a sealing slurry or some other connection that ensures a seal, for example a sealing adhesive, can be used. A significant advantage that results from the use of a sealing fleece is that the sealing fleece can also be perfectly adapted to an uneven surface. In addition, the sealing fleece can also be cut to size and in this way adapted to any complex geometries of the subsoil. According to the invention, the same also applies to the attachment of the sealing fleece to a wall adjoining the drainage device.

The sealing fleece can be designed as a floor sealing fleece or as a wall sealing fleece and accordingly only be attached to the bottom of the wall drain device or only to an upper and optionally the lateral edges of the wall drain device. The sealing fleece can also be constructed in several parts or in one piece, with a one-piece design of the sealing fleece being particularly preferred according to the invention, since in this way any seams that could cause any sealing problems can be avoided. An arrangement of the sealing fleece around the inlet opening or the inlet opening of the wall drain housing is particularly preferred.

Furthermore, the wall drain device according to the invention can also have an odor trap and/or a hair trap, which are each accessible according to the invention via the inlet opening of the wall drain housing and can be removed if necessary. For this purpose, the odor trap and/or the hair trap are preferably arranged in a housing which is removably inserted into the wall drain housing. Alternatively, however, the housing for the odor trap and/or the hair strainer can also be designed in one piece with the wall drain housing.

It should also be pointed out that, particularly if the sanitary floor element according to the invention has more than one overhang serving as a drain, the wall drain device used according to the invention can also have a number of inlet or inlet openings, with a respective overhang then protruding into a respective inlet opening. In this case, each individual inlet opening can have an odor trap and/or hair sieve to be assigned; however, it is also conceivable that such an odor trap and/or such a hair trap is/are arranged in a common collecting drain line. Alternatively, a separate wall drain device can also be assigned to each overhang. This can be particularly advantageous in the case of large sanitary floor elements. It should also be pointed out 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, can be installed between the sanitary floor element and an adjacent wall, in particular between the sanitary floor element and the wall drain device. provided and arranged there in a state of use of sanitary floor element and wall drain device.

In this way, respective wall-side edges of the sanitary floor element according to the invention, or respective baffles, can be additionally sealed both against the floor or screed of a sanitary room and against the walls adjoining the sanitary floor element. With the help of the sealing device used in each case, any unevenness can also be leveled out, so that in any case it is reliably prevented that water penetrates 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 if such an additional seal makes sense, for example due to structural conditions.

The invention can thus be summarized as follows.

A combination of a wall drain with a shower surface, the water running off of which is guided directly and purposefully into the wall drain via the overhang, or flows into it, ensures that the water is safely transported away from the surface area of the sanitary floor element into the wall drain with few spatters. This represents a significant advantage, since avoiding splashes also reliably prevents any germs from being stirred up in the shower water. Any water splashing back while draining is also effectively reduced. The solution according to the invention thus represents a solution of the object according to the invention that is low in aerosol and minimizes the risk of infection. In addition, the solution according to the invention requires significantly fewer parts than the previous ones Sanitary floor elements, or shower trays or the like, which significantly reduces the risk of possible assembly errors when installing the sanitary floor element according to the invention. Furthermore, the shower surface according to the invention is self-supporting and can also be easily adapted and cut to the required sizes by using Quaryl or another synthetic resin, in particular mineral-filled synthetic resin.

A further advantage of the sanitary floor element according to the invention is that, compared to previous sanitary floor elements, fewer joints or no joints at all are required, apart from the sealing joint to the surrounding bathroom floor, which offers significantly fewer opportunities for dirt and adhesions.

Furthermore, the sanitary floor element according to the invention has a permanently closed, smooth and scratch-resistant surface, which ensures that water and any contaminants can easily flow off and be removed. Such a surface can be obtained, 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, as they occurred in the prior art and which received dirt, germs and bacteria and provided these breeding grounds, are present in the solution according to the invention, d. H. the sanitary floor element according to the invention no longer exists.

The possibility of cutting the sanitary floor element according to the invention also ensures good adaptation on the construction site if adaptations to the existing structure are necessary.

The design of the system structure according to the invention with few joints also ensures less stagnant moisture and thus less breeding grounds for bacteria and generally lower room humidity, as a result of which the hygienic conditions are additionally improved.

The slip resistance of the sanitary floor element according to the invention, in particular if it is made from Quaryl or another mineral-filled synthetic resin, represents another significant advantage of the solution according to the invention.

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 error than previous multi-part solutions.

Another significant advantage of the sanitary floor element according to the invention also results from the fact that the shower surface is equipped with an overhang and a drip edge, with the overhang protruding into an opening of a wall drain. This reduces splashing back of contaminated water standing in the drain. The solution according to the invention thus offers a high level of cleaning friendliness and the associated low ongoing maintenance costs. The higher scratch resistance compared to other materials due to the use of Quaryl advantageously results in a longer service life as well as higher chemical resistance and slip resistance, which reduces the risk of falls and thus any risk of liability, for example in public spaces.

Furthermore, in times of pandemics and widespread infections, low-aerosol solutions, such as those made available by the sanitary floor element according to the invention, are extremely advantageous. This applies in particular to bathrooms in the healthcare sector that have to be kept hygienically clean, but also to many areas of the hotel industry. Good accessibility to the drain also minimizes further cleaning and service costs.

In this context it should be pointed out that the wall drain can be provided with a panel, for example a stainless steel panel, which can be held magnetically, and with a hair trap and an odor trap.

Using Quaryl as the material for the sanitary floor element according to the invention also provides a valuable appearance, provides the advantages of a scratch-resistant material and a superior

Detergent resistance and high slip resistance. Despite the slip resistance, the material is still easy to clean, has a pleasant feel and is sound-absorbing and feels warm to the feet when walking on it. Another important criterion of using quaryl as a material for the Sanitary floor element according to the invention also consists in the fact that Quaryl is a particularly stable material, in particular for flat construction heights, which is particularly important in modernization or also in new construction and also represents an advantageous factor in terms of lower costs. Furthermore, the material can be cut to size and adjusted on the construction site, which in turn is an important advantage, especially for modernization measures. Furthermore, Quaryl can be sealed off particularly well from surrounding surfaces; Repairs to the material of the sanitary floor element are then also possible.

Furthermore, a safe and leak-free drainage of water can be ensured by a combination of the sanitary floor element according to the invention with a wall drain device, in particular a wall drain housing. For this purpose, an overhang of the sanitary floor element that serves as a drain extends directly into the wall drain housing, so that water running off can be safely fed to a sewage pipe without having to fear that water running off could possibly penetrate between the sanitary floor element and adjacent masonry.

Further embodiments of the invention result from the dependent claims.

In the following description, the same reference numbers are used for the same parts and parts with the same effect.

the 1 and 2 both show a schematic representation of a sanitary floor element 10 according to the invention according to 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 transitions seamlessly into an overhang 40 . The overhang 40 serves as a drain from the floor surface 30 of the sanitary floor body. Furthermore, the overhang 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 also has an upper side 50 which is formed by the bottom surface 30 of the sanitary floor body 20 . In addition, an underside 60 is arranged opposite the upper side 50 of the sanitary floor body 20 . On the underside 60 of the sanitary floor body, which at the same time represents the underside 60 of the overhang 40, a draining device 110 is arranged, which in particular 3 is easy to see. The dripping device 110 is designed in the form of a dripping groove, which ensures that any water droplets located on the underside 60 of the overhang safely drain into the wall drain.

Furthermore, in the 1 and 2 to recognize 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 rather can be integrated flush into the surrounding bathroom floor.

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 of essentially square design and, as shown in FIG figure 5 The sectional view shown along the section line AA can be seen along the section line AA, in each case laterally arranged gradients 120 which ensure that water flowing off flows to the center in the direction of the overhang 40 .

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

6 shows an exemplary schematic representation of an overhang 40 according to the invention, or a shower surface tongue, which protrudes into an inlet opening 240 of the wall drain housing 200 that preferably fits exactly. In this case, sealing fleeces 170, 180 seal the wall drain to the wall 190 and to the floor 150 of a sanitary room. The shower surface tongue 40 protrudes into the wall drain housing 200 with lateral surge strips 70 and a groove 110 to produce a drip edge on the underside of the shower surface 130 . Furthermore, an optional first seal 160 is arranged between the overhang 40 and the floor sealing fleece 170, which is preferably made of a sealing, permanently elastic adhesive and/or a sealing compound and/or a prefabricated seal or alternatively, but less preferably, made of mortar, which preferably has sealing properties has, can exist. 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 made in one piece with the wall drain housing 200 .

7 shows an exemplary schematic perspective representation of a shower surface tongue 40, which protrudes into the wall drain housing 200 used according to the invention. A wall sealing fleece 180 reliably seals the wall drain circumferentially to the wall 190 and a floor sealing fleece 170 to the floor 150 of the sanitary room. The shower surface tongue, ie the overhang 40 projects into the wall drain housing 200 with lateral walls in the form of surge strips 70 . The baffles 70 guide the water directly into the wall drain housing 200, so that no previously used seals, which would have to be serviced or could become permeable, have to be passed by the outflowing water.

According to the invention, the illustrated lateral edge 140 of the shower surface can also be omitted and the shower surface 130 can be made even flatter and more barrier-free in this way. 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.

8 shows an exemplary schematic perspective representation of a shower surface tongue 40, which is located in front of an insertion into the wall drain housing 200. The one-piece sealing fleece 170, 180 is attached all the way around the wall drain to the wall 190 and to the floor 150 of the sanitary room.

9 shows a schematic view of additional sealing areas for second sealing devices 230, which on the one hand can be installed between the wall 190 and the surge strips 70 on the end face of the shower area 130, but can also be arranged in the floor area 150 below the shower area 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 clogged.

The second sealing devices 230 between the floor 150 and the shower area 130 can also be applied more voluminously, so that the shower area 130 can be placed in a bed of mortar like tiles.

The second sealing devices 230 can generally include the following variants of seals:

Optional seal(s) between the wall and the front baffles of the shower area, which can optionally be attached to the shower area from the outside at the factory and, if necessary, can also be circumferential.

One or more seal(s) between the floor and the underside of the shower surface, which is/are attached to the floor either at the factory from below or otherwise before the shower surface is installed.

The respective seal(s), which can be designed as a strip, can optionally be pre-assembled at the factory on the shower surface and, if necessary, also be provided all around.

At this point it should be pointed out that all the parts described above, viewed individually and in any combination, in particular the details shown in the drawings, are claimed to be essential to the invention. Modifications of this are familiar to those skilled in the art.
