Description

The invention relates to a drainage system, which has a drainage arrangement. DE 20 2008 003 050 U1 discloses a shower channel arrangement which has a shower channel having a channel section for the drainage of a shower region and a shower plate which forms the shower region and which comprises an end section. The shower channel has a receptacle which is arranged laterally adjacent to the channel section, and into which the shower plate is inserted with its end section. DE 10 2007 043 327 A1 discloses a drainage device for the at least partial introduction into a floor of a space. The drainage device comprises at least one system part with a first section, which in the installed position extends along a wall of the space and on which wall tiles can be applied, for example. Furthermore, the drainage device comprises drainage means which are partly insertable into a floor of a space and which can be connected to a drainage pipe, wherein the drainage device further comprises at least one inlet opening into which waste water can enter, wherein the waste water entered into the inlet opening can be trapped in the drainage means. The drainage means and/or the inlet opening are at least acoustically separated from the at least one system part.

Accordingly, floor-like shower elements are known which have a drainage arrangement on an end side or on an end side region for draining the accruing shower water. The drainage arrangement usually has a drainage channel, which catches the shower water and leads it to a drainage pipe via an intermediate siphon. For this purpose, the tray element can be provided with an inclination which is oriented in the direction of the drainage arrangement, wherein the inclination is able to be directly introduced into the tray element or can be effected via correspondingly adjustable support elements.

Floor level showers have the advantage in that they are stepless, so they are barrier-free and therefore easily accessible. In addition, shower regions can also be individually adapted to the predefined installation situation, deviating from predetermined standard dimensions, in particular for shower trays. However, the problem here often arises of the positioning of the siphon or of the drainage pipe relative to the drainage arrangement or to the drainage channel, which is acoustically connected to a rising up wall. This results in a considerable noise potential, which under some circumstances can be quite disturbing.

In DE 10 2007 043 327 A1, the problem of noise development is to be solved in that the drainage channel is decoupled from the wall via acoustic damping elements.

This, however, requires an extremely complicated superstructure and further cost-intensive measures.

It is also disadvantageous with drainage arrangements arranged in or on the tray element in that, in particular, the shower channel is relatively narrowly dimensioned, so that cleaning is complicated and time-consuming. Nevertheless, the channel is so wide that it must be provided with a channel cover in order to prevent injuries, since the channel is arranged in the visible shower region and thus in a possible standing region of the user.

The prior art also includes the solution shown in EP 2 236 683 A1.

The invention is therefore based on the object of improving a drainage system of the type mentioned initially with simple means such that the drainage arrangement is, on the one hand, freely positionable and uncomplicatedly accessible, wherein the drainage arrangement should simultaneously be virtually invisible with improved sound insulation. A drainage system configured according to the invention has the features of Claim 1.

Advantageously, a drainage system is provided which, with its drainage arrangement, is arranged within the receiving element in the mounted state, wherein the drainage arrangement has no acoustically coupled contact with a wall, since the drainage arrangement can be arranged at a distance from it. The receiving element can be formed from a corresponding material. In a favourable embodiment, the receiving element can consist of a preferably sound-absorbing material.

Suitable materials for the receiving element are coated or non-coated sheets of plastic hard foam, the basic material of which is polyurethane or polystyrene. Other foams can also be used. Receiving elements made of metal, plastic or shaped bodies made of materials such as, for example, fibreglass, are conceivable without restricting the materials therefor. It is conceivable to use receiving elements made of building boards which can have suitable surface coatings. Basically, materials which are permanently moisture-resistant when used in damp spaces are suitable for producing the receiving element.

It is particularly advantageous in the sense of the invention that the drainage arrangement, in particular its siphon, can be arranged in a location-variable manner within the receiving element. In addition, the drainage arrangement is arranged within the receiving element, and thus arranged virtually invisibly, i.e., concealed. A special covering of the drainage channel is no longer required, since there is no longer any danger of an accident, because the drainage arrangement is arranged outside a standing region, i.e., virtually outside the actual shower region. The exemplary use in a shower region is, of course, not intended to be limiting. It is essential that a variable wall integration element is provided with which or by which any horizontally acting drainage type can be covered or concealed in a or in front of a wall surface. It is conceivable to use the drainage system with the receiving element on washing tables, on floors in swimming pools, wellness facilities or even in public WC facilities. To this extent, the receiving element or the wall integration element, which can also be referred to as a drainage integration element, can also be used separately from tray elements or existing floor constructions.

It is expedient in the sense of the invention when the receiving element is configured as a separate, box-like hollow body, which is configured as a front mounted box of a wall. The receiving element can thus be simply set in front of a wall in a simple manner, wherein the drainage arrangement can then be inserted or is inserted into the cavity of the receiving element in the mounted state.

In a simple embodiment, the receiving element has a dimension such that a cavity is formed which as viewed in the axial direction is longer than the width. In the sense of the invention, the length of the receiving element or of the cavity is the side which runs parallel to a wall, wherein the width is oriented perpendicularly away from the wall.

In a preferred embodiment, the length of the receiving element can be adapted to the longitudinal extent of the drainage arrangement or the drainage channel, but of course it can also be configured longer than this. If the receiving element is assigned to a tray element of a floor-like shower, it is favourable in the sense of the invention when the receiving element has at least an axial length which corresponds to the length of the corresponding end side of the tray element. Of course, the positioning of the (wall) drainage integration element is not limited to a longitudinal or transverse side or its dimensioning. For example, a diagonal (45°) profile or a corner solution of the drainage arrangement is conceivable. It is also possible to have a round profile of the drainage arrangement as viewed in plan view. The receiving element or the (wall) drainage integration element can advantageously be manufactured variably from the respective profile of the drainage arrangement, but also detached from it.

The height extension of the receiving element or of the cavity can also be adapted variably to the respective mounting condition or wishes of the future user. Thus, the receiving element can extend over the entire height, for example, of the shower region, but can also be configured to be substantially smaller, so that the receiving element is configured virtually as a pedestal so as to provide a storage surface for shower utensils or the like. It is, however, also conceivable to provide a stand assembly with a front mounting wall, as will be described in more detail below. Of course, sanitary fittings or the like can be arranged on the receiving element and/or on the front mounting wall or on the side facing the shower region, which also applies to the abovementioned purposes.

In order to be able to mount the drainage system, in particular the drainage arrangement within the receiving element or within its cavity, it is extremely advantageous in the sense of the invention when a corresponding region of the end side facing the exemplary shower region has a corresponding opening so that an open engagement end side is formed into which the drainage arrangement can be introduced. This can be done by pre-mounting the drainage arrangement, for example, on a tray element, or in the corresponding drainage end side region in the tray element, so that the tray element can be mounted with the drainage end side region and the drainage arrangement arranged therein within the cavity.

The dorsal web is mounted on the end side region of the tray element, which extends away from the drainage arrangement, so that this is crossed over by the receiving element. In a further preferred embodiment, extensions are arranged on the two sides of the receiving element, so that the receiving element is configured to be quasi C-shaped in a plan view.

It is possible that a corresponding structural element for accommodating a wall covering or the wall covering is attached directly to the wall on an upper side of the transverse web directly adjacent to the rising up wall. The tops of the transverse web could then also be covered with a suitable covering, such as, for example, tiles, so that, for example, the pedestal is formed in a suitable embodiment. However, it is also conceivable for a stand assembly which is adapted to the magnitude of the transverse extent of the transverse web to be arranged on the top side of the transverse web such that a free end side of the transverse web terminates flush with a front mounting wall which is arranged on the stand assembly so that the then formed surface is likewise provided with a corresponding covering, wherein fixtures and/or the like can be fastened to this newly formed wall, as already described above. A cavity is formed between the component and the rising up wall, in which corresponding insulation elements and supply lines or the like can be arranged between the wall and the front mounting wall. Of course, the stand assembly can also be placed on the extension and/or directly on the dorsal web, so that a transverse web could be dispensed with.

If the exemplary components of the tray element, the drainage arrangement and the receiving element are mounted, the engagement end side or the engagement opening formed between the optional transverse web and the tray element or the drainage arrangement can be closed with a suitable facing element.

The facing element, of course, has such a height extension that its lower end side facing the exemplary tray element is spaced from the tray element or the floor covering arranged thereon so that a water passage gap is formed in order, for example, to drain the shower region properly. A water passage gap is, of course, also provided for the other purposes mentioned above. Of course, the facing element can be arranged such that its upper side facing the (exemplary) shower region ends flush with the free end side of the optional transverse web or the surface of the front mounting wall facing the shower region so as to be able to apply a covering matched to the planned wall covering. An impact seal with a sealing strip may be provided between the covering arranged on the facing element and the covering of the front mounting wall.

In a preferred embodiment, the facing element is configured as a stainless steel trim which, in a further preferred embodiment, should at least be capable of being tiled at its upper side facing the shower region.

It is advantageous in the context of the invention if the facing element is arranged releasably in a reversible manner to the receiving element.

Forthis purpose, at least one retaining element is expediently provided.

To this end, the invention also proposes that a receiving element is provided in which the drainage arrangement is arranged in the mounted state, wherein the receiving element has an engagement opening which can be reversibly closed by a facing element, wherein the facing element can be reversibly secured to retaining elements arranged within the receiving element.

In an expedient embodiment, the retaining element has a fastening pin, which has a fastening end, wherein a holding device which can be adjusted relative to the fastening pin is arranged on the fastening pin.

For attaching the retaining element to the receiving element, it is advantageously provided that the retaining element has a thread at its fastening end. The thread is preferably configured as an external thread and can be connected with an internal thread configured corresponding thereto, which is arranged at a suitable location on the retaining element. The retaining element can thus be screwed either to the transverse web of the receiving element or to a suitable device arranged opposite thereto. However, it is essential that the retaining element can be mounted retroactively and engages neither with its free end side opposite the fastening end nor with the fastening end itself, so that a variable positioning of the drainage arrangement, in particular the siphon, is achievable. In the case of the aforementioned arrangement examples, the retaining element extends with its fastening pin virtually parallel to the dorsal web and thus perpendicular to the transverse web of the receiving element.

However, it is also conceivable to connect the retaining element with its fastening end to the dorsal web so that the retaining element is arranged with its fastening pin extending parallel to the transverse web and is thus arranged perpendicular to the base element extending within the cavity of the base element.

Depending on the installation position of the retaining element relative to the dorsal web, it is advantageously provided to provide a holding device which is arranged laterally relative thereto and which can be adjusted relative thereto, but wherein it is, of course, also possible to arrange the holding device which can be adjusted relative to the fastening pin to the fastening end of the fastening pin. In this advantageous embodiment, the holding device could then be arranged on the free end side of the fastening pin opposite the fastening end.

In a preferred embodiment, the adjustable holding device has a magnet element having a retaining element and an adjustment element arranged opposite thereto, which can be connected to a corresponding counter-adjustment element on the fastening pin. The adjustment element of the holding device can also be referred to as a threaded pin which can be screwed with a threaded bore configured corresponding thereto. The threaded bore can now be introduced into one of the longitudinal sides of the fastening pin in one of the embodiments so that the holding device can be adjusted laterally relative to the fastening pin. On the other hand, however, the threaded bore can also be arranged in the free end side of the fastening pin, so that the holding device is then arranged opposite the fastening end of the fastening pin.

It is essential that the holding device is adjustable relative to the fastening pin so as to be able to compensate for installation tolerances with respect to the facing element, since this surface should, in a preferred embodiment, naturally end flush with the free end edge of the transverse web of the receiving element.

It is advantageous in the embodiment of the retaining element in that the holding device has the magnet element so that the facing element can be connected releasably in a reversible manner to the receiving element or that the facing element covers the engagement opening releasably in a reversible manner.

This is particularly advantageous in that the drainage arrangement should be cleaned from time to time, wherein the facing element can be detached easily, but not unintentionally, from the retaining element due to the magnetic holder so that the engagement opening is released. The engagement opening is now selected so large that the entire drainage arrangement, in particular the drainage channel, is freely accessible, so that this is to be cleaned without complication. Access to the siphon, which may also be cleaned and possibly removed, is possible without complication in the invention.

Further advantageous embodiments of the invention are disclosed in the subclaims and in the following description of the figures. In the figures:

Fig. 1 shows a cross-section through an exemplary shower drainage system,

Fig. 2 shows an enlarged detail from fig. 1 with respect to the exemplary shower drainage system,

Fig. 3 shows a plan view of an exemplary shower region with a drainage arrangement arranged in a receiving element,

Fig. 4 shows a wall view on the installation situation according to fig. 1,

Figs. 5 to 7 show an exemplary retaining element in different embodiments and installation situations.

In the different figures, the same parts are always provided with the same reference symbols and are generally described only once.

Figures 1 to 3 show a drainage system 1, for example, a shower drainage system 1, which has a drainage arrangement 2 and a tray element 3. The drainage arrangement 2 is arranged at a drainage end side region or in the illustrated exemplary embodiment at a drainage end side 4 of the tray element 3.

The drainage arrangement 2 is connected to the tray element 3 and has a drainage channel 6, a siphon 5 connected thereto and a drainage pipe connected to the siphon.

The drainage system 1 having the drainage arrangement 2 and the tray element 3 is suitable in a preferred application for floor-level installation so that, in a preferred embodiment, a barrier-free shower region can be implemented. Floor coverings, for example, can be applied as tiles in the embodiment on the tray element 3, for example, on a free surface, wherein supporting feet can be arranged on the opposite bottom side, wherein however, the tray element can also rest on the floor with the bottom side. The tray element can be installed flush with the screed, placed on floor coverings such as, for example, wooden floor boards, or can be installed in them.

Floor drainage situations are conceivable with conventionally produced screeds in which a drainage arrangement, i.e., a floor drain, is introduced, wherein a tray element can be dispensed with. It is also possible to mount the tray element 3 on a superstructure, e.g., on a grid-like superstructure, which can also integrate the drainage arrangement. Further configurations with respect to tray elements provided with a sealing element (e.g., sealing film, sealing fleece), or tray elements with a groove receptacle are likewise conceivable.

The shower region 7 of the drainage system 1 is illustrated by way of example in fig. 3. The tray element 3 has an integrated inclination such that shower water is channeled towards the drainage arrangement 2, which is illustrated by the arrows 8 in fig. 3 by way of example.

The drainage arrangement 2 is arranged in a receiving element 9. The receiving element 9 is preferably configured as a separate, box-like hollow body, which is configured as a front mounted box of a wall 11 of the shower space. Although a shower drainage system is described by way of example, this is not intended to be limiting. It is generally conceivable to use a drainage arrangement 2 with a receiving element 9 or with a (wall) drainage integration element in the sanitary region, such as, for example, on washing floors, on floors in swimming pools, wellness facilities or public WC facilities. To this extent, the receiving element or the (wall) drainage integration element of tray elements or existing floor structures can also be used separately.

As can be seen in fig. 3, the receiving element 9 has a cavity 12, which as viewed in the axial direction is longer than the width of the receiving element 9. The cavity 12 can also be referred to as an installation space 12 for the drainage arrangement 2, wherein the drainage end side region of the tray element 3 can also be introduced into the installation space 12. In this case, the tray element 3 can then have a drainage arrangement 2 with a drainage channel 6 integrated therein, so that the tray element 3 is covered by the receiving element 9 in this region.

In this respect, the receiving element 9 advantageously has an open engagement end side 13 or engagement opening 13 into which the drainage arrangement 2 can be inserted.

As seen in the cross-section, the receiving element 9 is configured in the form of an L-shape with a dorsal web 14 and a transverse web 16 lying above extending perpendicularly therefrom, wherein the dorsal web 14 is arranged extending parallel to the wall 11 in the mounted state. The transverse web 16 is arranged on the upper side on the dorsal web 14.

As can be seen clearly from fig. 2, the receiving element is arranged standing with its foot side 18 on the free end side region 17 of the tray element 3 so that the transverse web 16 virtually forms a cover for the cavity 12. Of course, the foot side 18 can also be arranged rising up on a floor, for example, by the screed or concrete of the space.

As can be further seen in fig. 3, the dorsal web 14 has an extension 19 on its respective opposite longitudinal sides so that the dorsal web is configured to be virtually C-shaped in a plan view. In the exemplary embodiment shown in figs. 1 and 3, the dorsal web 14 is configured continuous between the extensions 19 opposite each other, wherein it is, of course, also possible to provide individual elements by means of suitable connecting means to form a dorsal web 14, so that this can also be designed with joints seen in the axial direction.

As can be further seen from fig. 3, the siphon is arranged by example in the centre, wherein the respective adjacent and adjoining drainage channels 6 are configured with a corresponding inclination from the outside towards the siphon 5.

The receiving element 9, which is illustrated by way of example in figs. 1 to 4, is configured as a front mounted box, which can be mounted in front of a rising up wall 11, in a particularly preferred embodiment.

It can be seen that the cavity 12 or installation space 12 is formed through the advantageous configuration of the receiving element 9 with the L-shaped design as viewed in the cross-section, in which the drainage arrangement 2 can be arranged.

It can be seen from figs. 1 and 2 that, in the illustrated exemplary embodiment, a stand assembly 21 is arranged on an upper side 20 of the receiving element 9 or the transverse web 16, to which a front mounting wall 22 can be attached. As can be seen in fig. 2, the front mounting wall 22 closes with its free end side 23 of the transverse web 16 with its side facing the shower region. The transverse web 16 can also be omitted, wherein the stand assembly 21 would rise up on the extensions 19 and/or the dorsal web. A cavity 24 is thus formed between the rising up wall 11 and the front mounting wall 22, into which, for example, supply lines can be introduced, before the front mounting wall or the front mounting walls 22 are connected with the stand assembly 21, closing the cavity 24. The side of the front mounting wall 22 facing the shower region can be covered with a suitable wall covering, for example with tiles 26, wherein a front mounting wall 22 produced in this way can, of course, also be used for attaching sanitary fittings, soap dishes or the like.

If the tray element 3 with the drainage arrangement 2 arranged thereon is mounted in the cavity 12 or the installation space 12, the engagement side 13 or the engagement opening 13 can be reversibly closed with a facing element 25.

The facing element 25 can, for example, be configured as a stainless steel screen or, in a preferred embodiment, can be tiled at its side facing the shower region. It is, of course, also possible to provide an impact seal with a sealing strip between the covering on the facing element 25 and the covering on the front mounting wall 22 or on the tile covering engaging therefrom in the direction towards the free end side 23.

The facing element 25 is thus connected releasably in a reversible manner to the receiving element 9, it is advantageous in the sense of the invention when retaining elements 27 are used for this purpose, which are arranged within the cavity 12 or within the installation space 12 of the receiving element 9. The design of the retaining elements 27 will be described in more detail below. It is advantageous that the retaining elements 27 can be mounted retroactively and removed.

The facing element 25 has such a dimension that at least the latter covers the two opposing extensions 19 of the receiving element 9 and the entire engagement end side 13. For example, the receiving element 9 only has a height of 120 mm, wherein the cavity 12 or the installation space has a width of 55 mm. The tray element 3 has, for example, a thickness of 30 mm, wherein the facing element 25 can have a thickness of 10 mm. The dimensions mentioned are understood to be only exemplary and by no means limiting.

Fig. 2 clearly shows that the facing element 25 is arranged such that its side facing the shower region closes flush with the free end side 23 of the transverse web 16. However, it is of course also be provided that the facing element 25 is arranged outside the cavity 12 or outside the installation space 12, and possibly to completely cover a partial region of the free end side 23 of the transverse web 16 or completely cover it.

Such an embodiment could then be advantageous when the previously described front mounting wall 22 would be fastened directly to the wall 11 so that an upper side of the transverse web 16 could then also be covered with a covering, so that a pedestal is virtually formed.

On the basis of the selected sectional view, only one retaining element 27 can be seen in figs. 1 and 2, wherein fig. 4 shows by way of example that two retaining elements 27 can be provided. Of course, more than two retaining elements 27 can also be provided, depending on the size of the engagement opening 13.

The retaining element 27 has a fastening pin 28 and a holding device 29 (fig. 5) arranged thereon. The fastening pin 29 has a fastening end 31 and a free end side 32 arranged opposite thereto. With the fastening end 31, the retaining element 27 or the fastening pin 28 is to be connected to the receiving element 9. This can take place at the transverse web and/or at the dorsal web 14.

In a favourable embodiment, it is provided that the fastening end 31 of the fastening pin 28 has an external thread which can be screwed with an internal thread sleeve configured corresponding thereto, which is located either in the dorsal web 14 or the transverse web 16.

The different fastenings and arrangements of the retaining element are shown in figs. 5 to 7.

The holding device 29 of the retaining element 27 is configured in a technically favourable manner as a magnet element or magnetic disc which has a retaining side 33 and a fastening side 34 opposite to it. An adjustment element 36 is arranged on the fastening side 34 and can be connected to a counteradjustment element configured corresponding to this attachment pin 28. The adjustment element 36 can also be referred to as a threaded pin which is introduced into a threaded bore configured corresponding thereto as a counteradjustment element on one side of the fastening pin 28.

The fastening pin 28 is configured as a square in cross-section, wherein the fastening end 31 is configured in a favourable configuration with a round outer circumference in order to be able to screw the fastening end 31 into the corresponding inner threaded sleeve. However, a sufficiently stable plug connection is also conceivable, wherein threads can be dispensed with.

In the embodiment shown in fig. 5, the retaining element 27 is connected with its fastening pin 28 to the transverse web 16 so that the fastening pin 28 is arranged extending parallel to the dorsal web 14. The holding device 29 is arranged on the side of the retaining element 27 facing the shower region so that the facing element 25 is held by the retaining element 27 by means of magnetic forces.

Since the facing element 25 is preferably configured as a stainless steel plate which is not magnetically attracted, corresponding magnetically active projections are naturally provided in the corresponding holding region to the holding device 29 so that a magnetic holding force can be produced. Naturally, magnetic stainless steels can also be used. It is also possible to use a corresponding magnetic material instead of the stainless steel plate, wherein it is also conceivable to arrange corresponding magnets or ferromagnetic inserts in the material of the facing element 25 used for the holding device 29.

The holding device 29 is adjustable relative to the fastening pin 28 due to the interaction of the adjustment element 36 with the counter-adjustment element arranged on the fastening pin 28. This can be seen by means of the rotary arrow 37 shown in fig. 5. Furthermore, the fastening pin 28 is connected to the transverse web 16 via its fastening end 31 in such a way that the free end side 32 of the fastening pin 28 opposite the fastening end 31 is spaced apart from the drainage arrangement 2 or the drainage channel 6.

The retaining element 27 thus has no contact with the drainage arrangement 2 or the drainage channel 6. However, because the retaining element 27 can preferably be mounted retroactively, the siphon can be arranged freely positionable in the longitudinal direction of the receiving element 9 at the respectively desired location, and the drainage groove 6 can clean itself better.

Of course, the inclination of the drainage channel 6 is adapted to the respectively present position of the siphon.

Via the interaction of the adjustment element 36 with the opposing adjustment element, the facing element 25 can also be positioned in such a way that its upper side facing the shower region can close flush with the free end edge 23 of the transverse web 16 or the corresponding surface of the front mounting wall 22. Such a fine adjustment is easily possible by screwing in or unscrewing the adjustment element 36 in or out of the adjustment element or the fastening pin 28.

Further, it can be seen that the facing element 25 is spaced with its bottom end side, which is arranged opposite the transverse web 16, relative to the tray element 3 or to the drainage channel 6, so that an inlet gap 35 for shower water is formed. This is shown in principle in figs. 5 to 7.

In the exemplary embodiment illustrated in fig. 6, the retaining element 27 is arranged, in comparison with the exemplary embodiment illustrated in fig. 5, in such a way that the free end side 32, which is arranged towards the fastening end 31 of the fastening pin 28, is spaced from the transverse web 16.

The fastening end 31 is in this case accommodated or screwed into a suitable holding device, wherein the threads can engage each other here again. It is essential that, even with this arrangement of the retaining element 27, the siphon is freely selectable in its position.

In the exemplary embodiment shown in fig. 7, a further fastening variant of the retaining element 27 is shown on the receiving element 9.

In this exemplary embodiment, the fastening end 31 is connected to the dorsal web, so that the free end side 32, which is opposite thereto, is oriented towards the shower region or the facing element 25.

In contrast to the previously described exemplary embodiments, the holding device is adjustably connected to the opposing adjustment element on the free end side 32 by the interaction of the adjustment element 36.

Of course, the retaining elements 27 can either be positioned according to the exemplary embodiments of figs. 5 to 7, wherein, of course, any combination is conceivable. For example, a retaining element 27 according to fig. 7 and another according to fig. 5 and/or fig. 7 could be mounted, to name only one of many possible combinations.

The invention advantageously provides a (wall) drainage integration element, wherein the drainage system 1, in particular with its drainage arrangement 2, is acoustically decoupled from a wall and is invisible, in which the drainage arrangement 2 is integrated in the receiving element 9, which in turn is concealed via the facing element 25. The receiving element 9 is preferably dimensioned in such a way that a sufficiently large inspection opening is formed in order, for example, to clean the drainage channel 6 and/or the siphon or to service it. It is, of course, also possible to not use the facing element 25, wherein, however, the installation space 12 would then be visible.

It is particularly favourable in the design and arrangement of the retaining elements 27 that these are arranged in a substantial embodiment in such a way that the position of the siphon is freely selectable within the installation space 12. The retaining elements 27 are removable, should they be troublesome during cleaning or servicing of the drainage arrangement 2. It is further important that the facing element 25 is held reversibly on the receiving element 9, so that a sufficiently large inspection opening can be made available as required.

As can be seen in figs. 2 and 4, a continuous tile surface can be produced which covers in each case the side of the front mounting wall 22 facing the shower region, the free end side 23 of the transverse web 16, but also the side of the facing element 25 facing the shower region. Since the facing element 25 with the wall covering arranged thereon is removable, an impact seal 38 with a sealing strip is expediently provided between the wall covering of the facing element 25 and the wall covering of the front mounting wall 22.

Finally, it is possible to provide a corresponding cavity 41 for the wall 11 laterally to the dry construction 39 correspondingly adapted to the receiving element 9, which can be seen, for example, in fig. 3. Insulation elements 42 can be arranged in the cavities 24 (fig. 2) and 41 (fig. 3), which also form a support of the front mounting wall 22.
