[0002] Foot bath unit and bathtub with foot bath unit The invention relates to a foot bath unit for arrangement within a bathtub, wherein the foot bath unit has a foot receiving space which is bounded downwards by a floor section and laterally by at least one wall section and is open at the top.

[0003] The invention also relates to a tub, in particular a bathtub or shower tray, with at least one such foot bath unit.

[0004] Soaking one's feet, especially in warm water, has long been recognized as a proven method for physical relaxation and well-being. It offers the benefits of restoring and maintaining the health of the human body by detoxifying and removing harmful substances such as toxins and other pathogens, and also serves as a preventative measure. It can also be considered a complement to personal hygiene, for example, through the addition of natural remedies such as herbal essences, oils, antibacterial and antiviral agents, or through the use of commercially available foot care and cleaning products. What often discourages regular use is the associated effort—especially filling the foot bath with appropriately warm water and its subsequent disposal without causing excessive flooding—as well as the space required and the cleaning and storage of suitable equipment.This also argues against the use of conventional sanitary bathtubs - for example, the water requirement when using a bathtub is far too high, as the entire tub has to be filled to a sufficient height, even though the feet take up very little space.

[0005] These problems have already been addressed by state-of-the-art solutions: Daniela Ofner 1537 2

[0006] For example, CH 265787 A1 shows a multi-purpose bathing facility with a shower and a container serving as both a foot bath and a sitz bath, one rim of which is designed as a seat. The approximately rectangular container has a lower depression in its base, which serves as a foot bath and can be covered with a wooden grate when a conventional shower bath is desired.

[0007] A particular disadvantage is that the bathing facility cannot be used for any other purpose while the foot bath is in use. Aside from the questionable hygiene of the wooden grate, cleaning, especially the lower part of the foot bath, is very difficult because one has to bend down very low to reach it.

[0008] DE 1 800532 A1 describes a bathtub with an anatomically more favorable shape, in which a substantially horizontal section transitions via a flat step serving as a buttock support into a gently rising section, to which a section rising at less than 45° follows at the head end of the bathtub. This allows the bather to rest in an anatomically favorable angle with their legs elevated.

[0009] Instead of lying down, the bather can also turn around and use the deepest part of the bathtub, which is equipped with a bottom valve, for foot baths, sit-down showers and contrast baths.

[0010] Here too, the disadvantages already described apply: the tub cannot be used for any other purpose while taking a foot bath, and cleaning is quite complicated. Additionally, the design of the floor makes standing in the tub difficult, so versatile use of the tub, e.g., for standing showers, is not possible. Daniela Ofner 1537 3

[0011] It is therefore an object of the invention to eliminate the described disadvantages of the prior art and to make it possible to perform foot baths in a simple, uncomplicated way.

[0012] This problem is solved according to the invention by a foot bath unit mentioned above in that the foot bath unit has a seat element, wherein, when the foot bath unit is arranged as intended in a tub, the seat element is arranged above the foot receiving area and the foot receiving area is separated from the interior of the tub by the wall section and the floor section is arranged at the same level or higher than the floor of the tub.

[0013] In this way, an existing bathtub can be used for foot baths without the need for additional infrastructure. Unlike filling an entire bathtub or shower tray with warm or hot water up to the minimum level required for a foot bath, only the foot bath area needs to be supplied with water, resulting in significant water savings. Furthermore, since the foot bath area is separate from the rest of the tub, the tub can be used normally for other purposes while the foot bath is being taken.

[0014] Ideally, the foot bath compartment should have at least one drain opening, preferably one that can be opened and closed. In other words, the drain opening can be opened and closed. This allows the water to be drained from the foot bath unit without having to lift or otherwise move it. The water flows into the interior of the tub and from there through the existing floor drain, enabling quick drainage without soiling the surrounding area. Furthermore, this also reduces the effort required to fill and empty the foot bath unit, as it does not need to be lifted or moved. This makes it easier on the back and particularly convenient for older people. Daniela Ofner 1537 4

[0015] In particular, the drain opening is located in the floor section, the wall section, or the transition area between the floor and wall sections. This prevents water from remaining in the foot bath unit after draining.

[0016] In principle, the drain opening of the foot bath unit can be closed with a stopper made of rubber or a similar material, which is removed manually when necessary. In one embodiment of the invention, the foot bath unit has at least one actuating element for opening and closing the drain opening. This ensures simple operation: before use, the drain opening can be closed using the actuating element; after the foot bath, it is opened with the actuating element, and the water drains out.

[0017] In one embodiment of the invention, the base section is at least partially, and preferably completely, inclined. In particular, the base section is inclined towards the drain opening. In other words, the base section slopes downwards towards the drain opening. Therefore, the level of the base section is lower in the area of ​​the drain opening than in areas of the base section further away from the drain opening. This facilitates the complete drainage of the water after the foot bath is finished.

[0018] To further improve usability, particularly with regard to the risk of injury and ease of use, the floor section and / or the wall section may be at least partially finished with a textured surface. If the floor section has a textured surface, the risk of slipping can be significantly reduced, especially when the person using the foot bath steps into the foot bath unit at the beginning of the application or gets up during or after the foot bath, e.g., to leave the foot bath unit. At the same time, the textured surface can... [Daniela Ofner 1537 5]

[0019] It can also be designed in such a way that the foot bath is supplemented by stimulating and massaging the soles of the feet or the legs, depending on whether the structure is only installed in the floor section, only in the wall section or - at least partially - in both sections.

[0020] The foot bath unit is preferably made of materials commonly used in sanitary ware. For example, sandstone, porcelain, stoneware, glass, or other ceramic materials, metal, or plastics, especially recycled plastics, can be used. Manufacturing by 3D printing with suitable materials is also possible. Further advantages arise if the foot bath unit, preferably the wall and / or floor section, is made of a heat-resistant material. This allows the foot bath unit to be filled with very hot water without sustaining damage. Additionally, the unit can be cleaned easily and naturally using hot water, possibly supplemented with natural, plant-based cleaning agents.

[0021] In one embodiment of the invention, when the foot bath unit is arranged as intended in a bathtub, the seat element is located in the area of ​​the upper side of the tub's rim, preferably resting at least partially on the upper side of the tub. The tub's rim can thus be used as a support for the seat element, making it possible to take foot baths in a very comfortable and relaxed position.

[0022] It is particularly advantageous if, when the foot bath unit is properly positioned in a bathtub, the foot area is located entirely within the tub. In other words, when used as intended, the foot bath unit is completely inside the tub. Ideally, the wall section should be... (Daniela Ofner 1537 6)

[0023] The upper edge of the wall section is lower than the rim of the bathtub. Specifically, when the foot bath unit is properly installed in a bathtub, the upper edge of the wall section is lower than the rim of the bathtub. This prevents problems if the foot bath compartment is overfilled, as the water simply overflows into the bathtub and drains away through the floor drain. At the same time, the unit is just as easy to enter as a conventional bathtub, especially a shower or bathtub.

[0024] In principle, the foot bath unit according to the invention can be filled in the bathtub via an existing faucet or a connected shower hose, depending on its arrangement. To further facilitate the use of the foot bath unit, at least one filling device connected to or connectable to a water supply is optionally provided.

[0025] In principle, the foot bath unit according to the invention can be placed or hung in existing bathtubs and put away again after use; however, it can also be permanently integrated into bathtubs. Accordingly, in one embodiment of the invention, the wall section is formed at least partially by the rim of a bathtub. Optionally, the bottom section is formed at least partially, preferably completely, by the bottom of a bathtub. Easier use and facilitated filling and draining of water are made possible if the bottom section is at least partially, preferably completely, at the same level as the bottom of a bathtub.

[0026] A particularly decorative integration into a bathtub can be achieved if the seat element is made as a single piece with the bathtub rim. Daniela Ofner 1537 7

[0027] If the foot bath unit is designed to be inserted or hung in existing bathtubs and then removed after use, it is advantageous to allow for the subsequent installation of the foot bath unit in an existing bathtub, so that the foot bath unit is visually perceived as a fixed component of the bathtub. For this reason, a further embodiment of the invention provides a fastening device, connected or connectable to the wall section and / or the floor section, for attaching the foot bath unit to a bathtub, preferably to the edge of a bathtub. This allows the foot bath unit to be hung in the existing bathtub, the foot bath to be taken, and the unit then removed.

[0028] The seat element may be designed as part of the fastening device.

[0029] Advantageously, the mounting device has at least one inner mounting part and at least one outer mounting part, wherein, when the foot bath unit is arranged as intended in a bathtub, the inner mounting part is located inside the bathtub and the outer mounting part is located outside the bathtub. By providing mounting parts both inside and outside the bathtub, a particularly stable mounting of the foot bath unit is possible, thus guaranteeing safe use and reducing the risk of injury.

[0030] In one embodiment of the invention, the inner and outer mounting parts are connected to each other. This makes the foot bath unit a compact unit and significantly reduces assembly effort.

[0031] If necessary, the inner mounting element is formed integrally with the wall section. In one variant, the inner mounting element is formed by the wall section itself. In another variant, the seat element is designed as part of the outer mounting element, preferably integrally with the outer mounting element. This allows the number of Daniela Ofner 1537 8

[0032] Reduce the number of individual parts of the unit, thus reducing manufacturing costs and assembly effort.

[0033] Optionally, the inner and outer mounting parts are connected to each other via a central piece. This allows for more flexible use. In one embodiment of the invention, the central piece is designed to be length-adjustable. In other words, the central piece is length-adjustable so that the distance between the inner and outer mounting parts can be changed. In this way, the foot bath unit can be easily adapted to different bathtubs. It is advantageous if the seat element is designed as part of the central piece, preferably integrally with the central piece.

[0034] To enable even better adaptation to different tubs, for example for use with bathtubs and shower trays, in a further variant of the invention the inner and / or the outer fastening part is / are designed to be length-adjustable.

[0035] Advantageously, at least one spacer element is provided on the underside of the floor section facing away from the footwell.

[0036] The spacer element may be height-adjustable. This ensures that water drains properly from the footwell and further improves adaptation to individual bathtub shapes.

[0037] In a further embodiment of the invention, a drainage channel is provided in the base section, preferably extending from the drain opening to the wall section. Optionally, the drainage channel is designed as a recess open in the direction away from the foot bath area. This also facilitates the drainage of water from the foot bath area when the foot bath unit is flexibly installed in a tub and removed after use. Daniela Ofner 1537 9

[0038] The object of the invention is further achieved according to the invention by a tub mentioned above, in particular a bathtub or shower tray, with at least one foot bath unit of the type described above.

[0062] Figure 1 shows a bathtub 100 as an example of a known sanitary tub. For clarity, the bathtub 100 is depicted with a very simple, rectangular shape. Of course, the following explanations also apply to differently designed bathtubs 100 with round or polygonal sections and a partially inclined tub bottom 104. The invention is explained below in connection with this bathtub, but it can also be applied to other sanitary tubs such as a shower tray, a baby bath, a bidet, or a bidet tub with a seat.

[0063] The tub 100 has an interior 101. The reference numeral 101 also designates the interior 101 of the tub 100. The interior 101 is laterally bounded by a tub rim 102, or by the wall 102 of the tub 100, which terminates at the top with an upper surface 103 of the tub rim 102. The interior 101 is bounded at the bottom by a tub floor 104, or the bottom 104 of the tub.

[0064] The terms above, below and side refer here to an orientation in a geodetic reference system, in this case, the arrangement of tub 100 or the components described below in the Earth's gravitational field.

[0065] The interior of the tub 101 can be filled with a liquid medium, e.g., water, due to the limitations imposed by the tub rim 102 and the tub base 104. A tap 105, a shower hose 106, or a shower head can be used for this purpose, either individually or in combination. For the sake of clarity, only one tap 105 is shown in the following embodiments; of course, a shower hose 106 can also be provided, either additionally or instead. Daniela Ofner 1537 12

[0066] Fig. 2 shows a first embodiment of the invention, in which a foot bath unit 1 according to the invention is arranged within a described tub 100'. The perspective view shows a foot receiving chamber 2 of the foot bath unit 1, which is laterally bounded by a wall section 4, partially formed by the tub rim 102', and is open at the top. The foot receiving chamber 2 is dimensioned to accommodate two feet of average size placed side by side.

[0067] The semi-transparent illustration of this embodiment in Fig. 3 shows that the foot bath compartment is bounded at the bottom by a floor section 3. The floor section 3 is at the same level as the floor 104' of the tub. Additionally, the foot bath unit 1 has a seat element 5 located above the foot bath compartment 2 in the area of ​​the upper surface 103' of the tub rim 102'. It can be seen in particular that the seat element 5 rests partially on the upper surface 103' of the tub rim 102'. The seat element 5 serves as a seat for a user of the foot bath unit 1, but can of course also be used for other purposes when not in use, e.g., as a storage surface.

[0068] Figure 3 shows that the foot chamber 2 has a drain opening 6, which in the illustrated embodiment is located in the wall section 4. The drain opening 6 can be opened and closed; for this purpose, an actuating element 7 is provided in the upper area of ​​the foot chamber 2. The drain opening 6 of the foot bath unit 1 connects the foot chamber 2 with the interior of the tub 101'. The tub 100' has its own bottom drain 107', through which water can be drained from the interior of the tub 101'. Water can thus flow from the foot chamber 2 through the drain opening 6 into the interior of the tub 101' and from there into the bottom drain 107'. In variants not shown, the drain opening 6 can also be located in the transition area between Daniela Ofner 1537 13

[0069] The drain may be arranged in floor section 3 and wall section 4 or be located in floor section 3, where it may be connected to its own drain pipe; in addition, several drain openings 6 may also be provided.

[0070] The wall section 4 separates the foot bath compartment 2 from the interior of the tub 101', with the foot bath compartment 2 being located entirely within the tub 100'. In other words, the wall section 4 is lower than the tub rim 102' of the tub 100', or rather, it is located below the top 103' of the tub rim 102'. Therefore, filling the tub with water using the tap 105' has no effect on the foot bath unit 1 or the foot bath compartment 2, at least as long as the water level remains below the upper edge of the wall section 4. Conversely, filling the foot bath compartment 2 with water—for example, using a shower hose (not shown here, see Fig. 1) or a dedicated filling device for the foot bath unit 1 (not shown)—has no effect on the interior of the tub 101'.

[0071] This means that for a foot bath, it is not necessary to fill the entire interior of the tub 101' with water, but only the foot bath compartment 2 of the foot bath unit 1, which is significantly faster and uses fewer resources. The foot bath compartment 2 can therefore be filled with water to any desired level, preferably at least high enough so that the user's feet are almost ankle-deep in the water. Since the wall section 4 is lower than the tub rim 102', using the foot bath unit 1 is also more comfortable, as the legs can be stretched while sitting and do not have to be bent for too long. At the same time, the tub 100' can continue to be used normally, independently of the foot bath. For example, while the foot bath unit 1 is being used, a second person can simultaneously use the tub 100' for a bath in the usual way. Daniela Ofner 1537 14

[0072] A second variant is shown in a top view in Fig. 4. The design is very similar to the first embodiment shown in Figs. 2 and 3, except that here the drain opening 6 is located in the bottom section 3. Fig. 5 shows a sectional view along line VV in Fig. 4. The bottom section 3, shown with a solid line, is at the same level and follows the same course as the tub bottom 104', thus showing a variant in which the bottom section 3 is formed by the tub bottom 104' of the tub 100'. The dotted line represents a variant in which the bottom section 3 is inclined. The sectional view shows that the bottom section 3 slopes down from the tub edge 102' towards a central plane 100a' of the tub 100'. Since the drainage opening 6 is also located near the part of the wall section 4 facing the central plane 100a', the floor section 3 in the dotted version is therefore inclined in the direction of the drainage opening 6.While the dotted variant shows a linear slope in the direction of the drainage opening 6, the slope can also be curved or only part of the floor section 3 can be inclined.

[0073] Fig. 5 also shows the previously described embodiment of the seat element 5, which projects beyond the outer surface of the tub rim 102' facing away from the central plane 100a' of the tub 100'. A variant is shown with dotted lines in which the tub rim 102' is thicker, so that the seat element 5 rests completely on the upper surface 103' of the tub rim 102. In a variant not shown, the seat element 5 can also be formed integrally with the tub rim 102' of the tub 100'.

[0074] In the embodiment shown in Figures 4 and 5, the foot bath unit 1 also has a filling device 12 connected or connectable to a water line. This allows the foot bath chamber 2 to be filled with water independently of a tap 105'. A corresponding operating device for regulating the water supply, both as Daniela Ofner 1537 15

[0075] The quantity and temperature are not shown for the sake of clarity.

[0076] The variants described so far have shown the foot compartment 2 or the wall section 4 of the foot bath unit 1 as separate from the seat element 5. Part of the wall section 4 was formed by the tub rim 102'. Fig. 6 shows a variant in which the wall section 4 extends along the tub rim side to the seat element 5 in the area of ​​the upper surface 103' of the tub rim 102' and is connected to it.

[0077] As explained above, for the sake of clarity, the invention is described in connection with a substantially rectangular tub 100'. A fourth embodiment in Fig. 7 shows a variant with a tub 100' having a substantially hourglass-shaped base – the described foot bath unit 1 is arranged in one side area, and the seat element 5 is large and curved at the level of the upper surface 103' of the tub rim 102'.

[0078] A fifth embodiment is shown in Fig. 8, where, unlike previous versions, the foot compartment 2 does not project into the interior of the tub 10T, but is designed as a recess in the tub rim 102'. While the seat element 5 is arranged on a side of the foot compartment 2 of the foot bath unit 1 facing away from the central plane 100a' of the tub 100', the parts of the upper surface 103' of the tub rim 102' next to the foot compartment 2 can also be used for sitting. Fig. 8 again shows the drain opening 6 in the bottom section 3, whereby, of course, the drain opening can also be located in the area of ​​the wall section 4 oriented towards the interior of the tub 10T, so that water can flow from the foot compartment 2 into the interior of the tub 10T and from there into the floor drain 107'. Daniela Ofner 1537 16

[0079] Previously, variants were described where the foot bath unit 1 is shown in conjunction with or combined with a tub 100'. Figures 9a to 16 show the foot bath unit 1 on its own or before its arrangement in a tub 100'. Figure 9a in perspective view and Figure 9b in semi-transparent view show the already known construction of the foot bath unit 1 with a foot receiving chamber 2, which is bounded by a wall section 4 connected to a seat element 5. The semi-transparent view in Figure 9b shows the drain opening 6 in the floor section 3, which can be opened and closed with the actuating element 7.

[0080] To attach the foot bath unit 1 to a tub 100, 100' – in particular to the tub rim 102, 102' – a fastening device 8 is provided. In the embodiment shown in Figures 9a and 9b, this is formed by the seat element 5 and its connection via the wall section 4 to the floor section 3. The seat element 5 is part of the fastening device 8.

[0081] Figures 10a and 10b show, in perspective and semi-transparent views, a variant in which the fastening device 8 has an outer fastening part 9 and an inner fastening part 10. The terms "inner" and "outer" refer to an intended arrangement of the foot bath unit 1 in a tub 100, 100', in which the inner fastening part 10 is located inside the tub 101, 10T and the outer fastening part 9 is located outside the tub. In the embodiment shown in Figures 10a and 10b, the inner fastening part 10 is formed by the connection of the wall section 4 with the seat element 5 and is essentially integral with the wall section 4, or, in a variant, can also be formed entirely by the wall section 4. The outer fastening part 9 is designed as a projection of the seat element 5, which extends downwards towards the floor section 3 of the footwell 2, Daniela Ofner 1537 17

[0082] protrudes from the seat element 5. The outer fastening part 9 is therefore integrally formed with the seat element 5.

[0083] When the foot bath unit 1 is arranged in a tub 100, 100' according to Figs. 10a, 10b, the inner fastening part 10 is located inside the tub 101, 101', the projection of the seat element 5 as outer fastening part 9 prevents the foot bath unit 1 from moving towards the tub interior 101, 101'.

[0084] Figures 11a and 11b show an eighth embodiment in which the inner mounting part 9 and the outer mounting part 10 of the mounting device 8 are connected to each other via a central piece 11. The inner mounting part 9 is designed as strips that are connected to the wall section 4 of the foot recess 2, the central piece 11 is formed integrally with the seat element 5, and the outer mounting part 10 is formed by two upright elements that extend from the seat element 5 down to the level of the floor section 3, as can be seen particularly in Figure 11b, which shows a side view of the perspective view from Figure 11a.

[0085] Particularly flexible adaptation to different applications, or adjustment for various bathtubs (100, 100') and / or sanitary facilities, is possible if the inner mounting part (10) and / or the outer mounting part (9) are length-adjustable. They can be length-adjustable together, simultaneously, or individually.

[0086] Fig. 12 shows a side view of a variant in which only the outer mounting part 9 is length-adjustable. This allows for adaptation to tubs 100, 100' where the tub bottom 104' is significantly higher or lower than the surrounding area of ​​the tub 100, 100'. Daniela Ofner 1537 18

[0087] The embodiment shown in Fig. 13 demonstrates that the length of both the inner 10 and the outer fastening parts 9 is adjustable. This provides maximum flexibility.

[0088] Additionally, the variants in Figs. 12 and 13 feature spacer elements 13 arranged on the underside 3a of the base section 3, facing away from the foot bath chamber 2. According to the variant in Fig. 13, these spacer elements can also be height-adjustable. This ensures, for example, that water can drain from the foot bath chamber 2 even if the drain opening 6 is located in the base section 3 of the foot bath unit 1. Situations may arise where the base 104, 104' of the tub 100, 100' at least partially blocks the drain opening 6; this problem is solved by the spacer elements 13. Furthermore, the adjustable length of the spacer elements 13 allows for optimal adaptation to users of different heights. Those with shorter legs can extend the spacer elements 13, thereby achieving greater comfort when taking a foot bath.

[0089] Figures 14 and 15 show a variant of the invention in which the length of the central piece 11 can be adjusted. In other words, the central piece 11 can be designed to be length-adjustable. In the illustrated embodiment shown in Figures 14 and 15, this is achieved by the central piece 11 consisting of two telescoping parts. The distance between the inner 10 and the outer mounting part 9 can thus be changed, making it possible to use the piece with tubs with tub rims 102, 102' of different thicknesses. In Figures 14 and 15, a first position of the outer mounting part 9 is shown with a solid line, and a second position of the outer mounting part 9 with a shortened central piece 11 is shown with a dashed line. The telescoping parts of the central piece 11 can also be spring-loaded, so that it is held against spring force.

[0090] is extended and contracted by spring force, causing it to jam against the edge of the tub 102, 102'.

[0091] In the eleventh embodiment according to Fig. 14, one of the parts of the central piece 11 functions as a seat element 5. In other words, in one variant, the length-adjustable central piece 11 functions as a seat element 5. Both functionalities are thus combined in the central piece 11.

[0092] Fig. 15 shows an embodiment in which, in addition to the central section 11, a separate seat element 5 is provided, which is mounted on the central section 11. In other words, in one variant, a separate seat element 5 is provided on the length-adjustable central section 11. In particular, depending on the embodiment, the seat element 5 is mounted on that part of the central section 11 that does not move when the length of the central section 11 is adjusted. In this embodiment, comfort can be increased in particular, since the seat element 5 remains stationary and can therefore, for example, be made of an elastic, soft material.

[0093] Naturally, the length adjustability of the central piece 11 can be combined with the adjustability of the fastening elements 9, 10 according to Figures 12 and 13 in variants not shown in the figures, whereby either only the inner 10 or only the outer fastening element 9 can be length-adjustable. Additionally or instead, the spacer elements 13, optionally also length-adjustable, can be provided.

[0094] Fig. 16 shows a perspective view of how a foot bath unit 1 – here in the embodiment according to Figs. 11a and 11b – is hung over the rim 102' of a tub 100' or rests on the upper surface 103' of the rim 102', so that a foot bath can be taken and the tub 100' can be used for other purposes at the same time. The foot bath unit 1 with solid lines represents the state before installation. Daniela Ofner 1537 20

[0095] The foot bath unit 1 is shown with dashed lines in the assembled state, in which the foot bath unit 1 is hung over the edge 102' of the tub 100'.

[0096] While, for the sake of clarity, foot bath units 1 with a substantially rectangular base area for the foot chamber 2 have been predominantly described so far, Fig. 17a shows an example of a variant with a semicircular base area, and the variant according to Fig. 17b is designed with a polygonal, in this case hexagonal, base area. Other variants are also possible.

[0097] The problem of insufficient drainage of water through the drain opening 6, when it is located in the base section 3 and possibly at least partially obscured by the tub bottom 104, 104', has already been described in connection with the embodiments according to Figs. 12 and 13. A different solution is shown in Fig. 18: Here, a drainage channel 14, indicated by dashed lines, is provided in the base section 3, extending from the drain opening 6 to the wall section 4 and opening there into the area surrounding the foot bath unit 1. In other words, the drain opening 6 is connected to the area surrounding the foot bath unit 1 via the drainage channel 14, so that water can drain away even when the foot bath unit 1 is lying flat on a surface. The drainage channel 14 can either run completely within the base section 3 or be formed as a groove or channel in the underside 3a of the base section 3.The recess should be open in a direction away from foot reception area 2.

[0098] The foot bath unit 1 in the described embodiments can be made of a wide variety of materials, preferably those commonly used for manufacturing sanitary bathtubs, such as ceramic, plastic, or similar materials. Manufacturing by means of 3D printing is also possible. Advantageously, a heat-resistant material is chosen that, on the one hand, allows for the administration of [Daniela Ofner 1537 21]

[0099] The foot bath unit 1 allows for both high-temperature foot baths and cleaning with very hot media to guarantee deep cleanliness and sterility. It can also withstand the addition of various natural remedies such as herbal essences, oils, and antibacterial and antiviral foot treatments, further enhancing the effectiveness and comfort of the foot baths. This is also possible with the variant shown in Fig. 19, where the foot bath unit 1 is partially—here in the area of ​​the base section 3—featuring a textured surface. This can, for example, provide an additional massage effect. In variants not shown, only the wall section 4 or the base section 3 and the wall section 4 are provided with such a textured surface.

[0100] The described foot bath unit 1 according to the invention can be used more frequently as a permanent fixture in the bathroom, or, according to embodiments, combined with a tub 100, 100', since cleaning effort is significantly reduced and setup and storage are made easier. Especially in stressful times like today, the invention enables quick, practical use with great success, without causing additional work. This allows foot bathing to become a regular part of the daily routine again, thereby increasing well-being. In this way, the benefits of restoring and maintaining health, as well as preventative care, can be achieved. Daniela Ofner
