[0008] First, embodiments of the present disclosure will be listed and described. Any combination of the following multiple embodiments within a range that does not cause contradictions is also included in the description of the present invention.

[0009] [1] The bathroom of the present disclosure is equipped with a first hanging member that can hang a bathtub having a sheet-made bathtub body that is used to fill with hot water so that it does not touch the floor. [2] The bathroom of [1] above is provided with a plurality of second hanging members that can hang the bathtub in a state where it can be filled with hot water and used, and the first hanging members are positioned higher than the second hanging members. [3] In the bathroom of [2] above, the bathtub has a hook that can be hooked onto both the first hanging member and the second hanging member. [4] The bathroom of either [2] or [3] above is provided with a pair of the first hanging members and a plurality of the second hanging members, and the spacing between the pair of first hanging members is wider than the spacing between a pair of the second hanging members provided on the same wall. [5] In any of the bathrooms described in [1] to [4] above, the first hanging member is provided on a wall opposite to the wall on which the shower device is located.

[0010] <Embodiment 1> A bathroom 1 according to a first embodiment of the present disclosure will be described with reference to the drawings. As shown in Figures 1 and 2, the bathroom 1 has a bathtub 10. The bathroom 1 is rectangular. The bathroom 1 has walls W1, W2, and W3 and a floor F. The bathroom 1 is surrounded by walls W1, W2, and W3 on three of the four sides of the floor F when viewed from above. A wall with an entrance (not shown) is located on the other side of the floor F.

[0011] As shown in Figures 1 to 3, bathroom 1 is equipped with a shower system 2. Shower system 2 is located on wall W1, one of walls W1, W2, and W3. Shower system 2 is located on wall W1, closer to wall W3. Shower system 2 includes a faucet 3, an overhead shower 4, and a hand shower 5. Faucet 3 is formed in a long cylindrical shape extending horizontally along the surface of wall W1. Faucet 3 is connected to a water supply pipe and a hot water supply pipe (not shown) within wall W1. Faucet 3 is a mixer faucet. Faucet 3 can adjust the water volume, adjust the temperature by mixing hot and cold water, stop the water supply, and switch the flow path. In this specification, hot and cold water supplied from a faucet installed in a bathroom is referred to as hot and cold water, regardless of the temperature, mixing ratio, etc. Faucet 3 includes a water outlet pipe 3A. Faucet 3 can select either the water outlet pipe 3A, the overhead shower 4, or the hand shower 5 to dispense hot and cold water.

[0012] A bathtub 10 is installed in the bathroom 1. As shown in Figure 1, the bathtub 10 is attached to a pair of opposing walls W1 and W2 out of the three walls W1, W2, and W3. The bathtub 10 is removably attached to the walls W1 and W2. In other words, when the bathroom 1 is being used for a purpose other than its intended use, the bathtub 10 can be removed and used. For example, as shown in Figure 2, the bathroom 1 can be conveniently used as a shower room by removing the bathtub 10.

[0013] As shown in Figures 1 and 2, each of the pair of walls W1 and W2 has a second hanging member 20. The bathtub 10 is attached by hanging it on the second hanging member 20. The second hanging member 20 is a hook-shaped member that is J-shaped in a side view and opens upward. Two second hanging members 20 on the wall W1 side are arranged below the faucet 3 and spaced apart horizontally. Two second hanging members 20 on the wall W2 side are provided at the same height and with the same spacing as the second hanging members 20 on the wall W1 side. In other words, two second hanging members 20 are provided on each of the pair of walls W1 and W2, for a total of four. Each second hanging member 20 hangs the bathtub 10 by hooking a loop portion 41 (described later) on the bathtub 10.

[0014] As shown in FIGS. 1 to 3, the bathroom 1 has a pair of first hanging members 21. Each first hanging member 21 is a member for temporarily hanging the bathtub 10 after use to drain or dry it, by hooking a loop portion 41 (described later) of the bathtub 10 onto the first hanging member 21. Each first hanging member 21 is provided on the wall W2 opposite the wall W1 on which the shower device 2 is located. Each first hanging member 21 is provided above the second hanging member 20, at a height that is within reach of an average adult woman, and at a height such that the hanging bathtub 10 does not come into contact with the floor F. Specifically, each first hanging member 21 is provided at a height of approximately 1700 mm to 1750 mm above the floor F. The spacing between each first hanging member 21 is the same as the spacing between the pair of second hanging members 20 provided on the wall W2.

[0015] As shown in FIG. 4, the first hanging member 21 has a base portion 21A, an intermediate portion 21B, and a tip portion 21C. The base portion 21A is disk-shaped. The back surface of the base portion 21A is attached in contact with the wall W2. The intermediate portion 21B is cylindrical. The intermediate portion 21B is continuous with the center of the front surface of the base portion 21A. The outer diameter of the intermediate portion 21B is approximately 3 / 10 of the outer diameter of the base portion 21A. The length of the intermediate portion 21B is approximately 3 / 2 of the thickness of the base portion 21A. The tip portion 21C is disk-shaped. The tip of the intermediate portion 21B is continuous with the center of the back surface of the tip portion 21C. The outer diameter of the tip portion 21C is approximately 5 / 2 of the outer diameter of the intermediate portion 21B, which is smaller than the outer diameter of the base portion 21A. The thickness of tip portion 21C is approximately 2 / 5 the length of intermediate portion 21B and is thinner than the thickness of base portion 21A. The central axes of tip portion 21C, intermediate portion 21B, and base portion 21A are aligned on the same straight line. The difference ΔR between the outer diameter of tip portion 21C and the outer diameter of intermediate portion 21B is slightly smaller than the outer diameter of rope 40 that constitutes loop portion 41, which will be described later. The length L of intermediate portion 21B is approximately 3 / 2 the outer diameter of rope 40. For this reason, the first hanging member 21 cannot hook two loop portions 41 together.

[0016] Bathtub 10 is detachably attached to a pair of walls W1, W2. Bathtub 10 can be deformed to store hot water. Bathtub 10 can freely change its shape, such as being folded or unfolded. Bathtub 10 stores hot water when unfolded. Bathtub 10 is boat-shaped when suspended, which is the state in which it is used.

[0017] As shown in Figure 5, the bathtub 10 is composed of a bathtub body 30 and a rope 40. The bathtub body 30 can hold hot water. The bathtub body 30 is made of a sheet. When in use and filled with hot water, the bathtub body 30 has a rectangular shape in a plan view. When in use, the upper edge of the bathtub body 30 opens upward. When in use, the bathtub body 30 gradually widens from the bottom end to the top end.

[0018] As shown in Figure 5, the bathtub body 30 has four side walls: first to fourth side walls 30A, 30B, 30C, and 30D. The first and second side walls 30A and 30B extend downward from a pair of opposing long sides in a plan view. The third and fourth side walls 30C and 30D extend downward from a pair of opposing short sides in a plan view. Both end edges of the third and fourth side walls 30C and 30D are continuous with both end edges of the first and second side walls 30A and 30B.

[0019] The bathtub body 30 is made of sheet S1. As shown in Figure 6, sheet S1 is cut into a predetermined shape from a single sheet material. The bathtub body 30 is formed by joining the joining pieces J and folding back the folded piece T in the sheet S1 shown in Figure 6. The joining pieces J are joined to form the joining portion 31 described below. The folded piece T is folded back and sewn to form the folded portion 32 described below. The sheet material that makes up sheet S1 is flexible and deformable, yet has excellent durability against external physical and mechanical influences, especially external tensile forces, and is impermeable (waterproof). The sheet material that makes up sheet S1 has little elasticity, and retains its boat-shaped shape to a certain extent when filled with hot or cold water.

[0020] Specifically, the sheet S1 is composed of multiple overlapping layers. As shown in FIG. 7, the sheet S1 has two layers: a first layer L1 and a second layer L2. The sheet S1 is a single sheet cut out from a sheet material in which the first layer L1 and the second layer L2 are bonded together with an adhesive A. The first layer L1 ensures water impermeability. The second layer L2 ensures durability. The first layer L1 is positioned closer to the inside of the bathtub 10 than the second layer L2. Specifically, in the two-layer sheet S1, the first layer L1 is located on the innermost side, and the second layer L2 is located on the outermost side.

[0021] In the sheet S1, the first layer L1 is a film layer made of resin or the like. Specifically, the first layer L1 is made of polyurethane (PU) film. The smooth surface of this first layer L1 is exposed on the inner surface of the bathtub body 30. In the sheet S1, the second layer L2 is made of fabric such as woven fabric. The second layer L2 is made of polyester resin fiber, specifically, woven fabric made of polyethylene terephthalate (PET) fiber. PET fibers are excellent in water resistance, heat resistance, chemical resistance, etc. The weave of the woven fabric second layer L2 is a plain weave, which is considered to be excellent in strength and durability among various weaves. The fabric surface of the second layer L2 of the sheet S1 is exposed on the outer surface of the bathtub body 30. In other words, the plain weave fabric surface of the second layer L2 is exposed on the outer surface of the bathtub 10, and the PU film surface of the first layer L1 is exposed on the inner surface. In the sheet S1, the fabric surface of the second layer L2, which is the outermost surface, is rougher than the surface of the first layer L1, which is the innermost surface.

[0022] As shown in Figure 5, the bathtub body 30 has a joint 31 and a folded portion 32. The joint 31 joins the sheets S1 together. The joint 31 is the portion where the joining pieces J (see Figure 6) provided on the edges of the cut sheets S1 are joined together. The joint 31 is formed on the side wall of the bathtub body 30. Specifically, the joint 31 is formed on the side wall 30C, 30D that forms the shorter side of the rectangle among the four side wall 30A, 30B, 30C, 30D of the bathtub body 30. The joint 31 extends in the vertical direction at the center of the extension direction of the sides of the side wall 30C, 30D. The provision of such joint 31 allows the bathtub body 30 to form a boat-shaped shape.

[0023] As shown in FIG. 8 , the joint 31 is formed by thermally welding two overlapping joint pieces J with a thermal welding material H sandwiched therebetween. In the joint 31, the two joint pieces J are each bent into a U-shaped cross section and interlocked with each other. The joint 31 includes a first welding portion H1 where the first layer L1 of the sheet S1 is welded together, a second welding portion H2 where the second layer L2 is welded together, and a third welding portion H3 where the first layer L1 is welded to the second layer L2. The first welding portion H1 and the second welding portion H2 are made of the same material and are welded together using a thermal welding material H suitable for welding the respective materials. In this embodiment, a PU film is used for the first layer L1, and a PET woven fabric is used for the second layer L2. For this reason, PU-based and polyester-based thermal welding materials are suitable for the thermal welding material H used for the first welding portion H1 and the second welding portion H2, respectively. The third welded portion H3 is formed by welding dissimilar materials together, using a welding material selected in consideration of the properties of both materials. In this embodiment, the third welded portion H3 is formed using the same heat-sealing material H as the heat-sealing material H used for the second welded portion H2. The heat-sealing material used for the third welded portion may be the same as the heat-sealing material used for the first welded portion, or may be a heat-sealing material different from the heat-sealing materials used for the first welded portion and the second welded portion.

[0024] The folded portion 32 is formed by folding back and overlapping the outer edge of the sheet S1 that forms the bathtub body 30. The folded portion 32 is maintained in an overlapped state by sewing the folded sheets S1 together. As shown in FIG. 3, the folded portion 32 is formed around almost the entire outer edge located at the upper edge of the bathtub body 30 when in use. Because the folded portion 32 has a double-layered structure, it also functions as a reinforcing portion at the upper edge of the bathtub body 30.

[0025] As shown in FIG. 5, the folded portion 32 has a wide portion 32A and an insertion portion 32B. The wide portion 32A is located in the portion corresponding to the four corners of the rectangular bathtub body 30 in a plan view. The wide portion 32A is wider than the other portions by setting a large folding margin. The insertion portion 32B is the folded portion 32 of the folded portion 32 that corresponds to the long sides of the rectangular bathtub body 30 in a plan view. As shown in FIG. 9, the insertion portion 32B is cylindrical, and a rope 40 is inserted inside. The insertion portion 32B, together with the wide portions 32A on both ends, is formed by a series of folding pieces T. The cylindrical space inside the insertion portion 32B is connected to the space inside the wide portions 32A at both ends. The rope 40 inside the insertion portion 32B extends to the wide portions 32A at both ends.

[0026] The rope 40 suspends the bathtub body 30 when the bathtub 10 is in use. As shown in FIG. 5, the rope 40 is arranged on the upper edges of the side walls 30A, 30B, 30C, and 30D of the bathtub body 30, which are rectangular in plan view. In other words, when the bathtub 10 is installed, the bathtub body 30 is suspended from the rope 40 at the upper edges of the two opposing side walls 30A and 30B. The rope 40 is inserted into the wide portion 32A and the insertion portion 32B of the folded portion 32 of the bathtub body 30. The rope 40 extends continuously from the wide portion 32A at one end to the wide portion 32A at the other end. This allows the rope 40 to function as a reinforcing member that reinforces the upper edge of the bathtub body 30 when suspended. As shown in FIG. 10, the rope 40 has a loop portion 41. The loop portions 41 correspond to the engaging portions according to the present disclosure. The loop portions 41 are provided on both ends of the rope 40. The loop portions 41 expose the rope 40 in a loop shape to the outside from the wide portion 32A, and return the ends of the rope 40 to the inside of the wide portion 32A to secure them to the wide portion 32A.

[0027] When in use, suspended from the rope 40, the bathtub body 30 has a boat-like shape with a downward recess in the center. When in use, the upper edge of the bathtub body 30 opens upward. When in use, the bathtub body 30 has a boat-like shape that gradually widens from the bottom to the top. When filled with hot water, the underside of the center of the bathtub body 30 comes into contact with the floor F of the bathroom 1. This allows the floor F to support most of the weight of the bathtub 10 when it is filled with hot water. Therefore, the reinforcing structure of the walls W1 and W2 can be simplified compared to when the bathtub 10 is supported only by the walls.

[0028] As shown in FIG. 1, the loop portion 41 serving as an engagement portion is hooked onto the second hanging member 20 provided on the walls W1 and W2. The loop portion 41 is provided on the upper edge of the bathtub 10. Specifically, as shown in FIG. 5, the loop portion 41 is provided on the four corners of the bathtub main body 30, which is rectangular in plan view. The bathtub main body 30 is suspended from the second hanging member 20 via a rope 40 with the loop portion 41 hooked onto the second hanging member 20. The bathtub 10 is removably attached to the walls W1 and W2 by hooking the loop portion 41 onto the second hanging member 20.

[0029] As shown in Figure 4, the loop portions 41 are hooked onto each of the first hanging members 21 provided on the wall W2. Specifically, by hooking a pair of loop portions 41 provided on both ends of the folded portion 32 on either the third side wall portion 30C or the fourth side wall portion 30D of the bathtub body 30 onto each of the first hanging members 21, the bathtub 10 can be temporarily hung after use to drain or dry.

[0030] The function and effect of the bathtub 10 and bathroom 1 configured as described above will now be explained. The bathtub 10 can be attached and detached freely to the walls W1 and W2 of the bathroom 1. This makes it extremely easy to install and store the bathtub 10. When installing the bathtub 10, it can be installed simply by hooking the four loop portions 41, which serve as engagement parts, onto the second hanging member 20 on the walls W1 and W2. The bathtub 10 is hung from the second hanging member 20, and in this state, hot and cold water is filled in the bathtub main body 30 and used.

[0031] The bathtub 10 has a rope 40 inserted into the insertion section 32B in the folded section 32 at the upper edge of the bathtub main body 30. The rope 40 has a loop section 41 as an engagement section. The rope 40 is hung between the second hanging members 20 of each wall W1, W2 at the loop sections 41 at both ends. The bathtub main body 30 is hung while distributing the load over approximately the entire length of the rope 40 in the extension direction. Therefore, when the bathtub 10 is hung, localized load imbalance can be suppressed on the sheet S1 that forms the bathtub main body 30.

[0032] The folded portion 32 is maintained in its folded state by sewing. The folded portion 32 is located at the upper end of the bathtub body 30 when in use. The water level of the bathtub body 30 when in use is usually located below the upper end of the bathtub body 30. For this reason, the folded portion 32 does not require strict water impermeability like the joint portion 31; it is sufficient if it can maintain its folded state. For this reason, using sewing to maintain the folded portion 32 is useful as it allows the folded state to be maintained in a simple manner. The sewn folded portion 32 can add a design such as a stitch to the upper edge of the bathtub body 30.

[0033] The folded portion 32 is formed by folding the upper edge of the bathtub body 30 outward when the bathtub 10 is in use. With this folded portion 32, the inner surface of the bathtub body 30 is composed only of the surface of the first layer L1. This first layer L1 is made of PU film, and is the layer that ensures the impermeability of the bathtub body 30. Therefore, the folded portion 32 is advantageous from the standpoint of waterproofing.

[0034] For example, in the case of a folded portion that is folded inward toward the bathtub body, the surface of the layer that constitutes the outer surface of the bathtub body is exposed to the inside of the bathtub body. In this case, if the outer surface of the bathtub body is composed of the surface of a fabric such as a woven or knitted fabric like the second layer L2 of this embodiment, water is likely to seep into the gaps in the woven or knitted fabric due to splashes of hot or cold water. In contrast, in the case of the folded portion 32 that is folded outward, the surface of the second layer L2 is not exposed to the inside of the bathtub body 30, which prevents hot or cold water from coming into contact with the second layer L2, making such a situation less likely to occur.

[0035] The folded portion 32 has excellent design properties because the upper edge of the bathtub body 30 is folded outward when the bathtub 10 is in use. In other words, because the folded portion 32 is folded outward, there is no step on the inner surface of the bathtub body 30 that would occur if it were folded inward.

[0036] To fill the bathtub 10 with hot water, the faucet 3 in the shower device 2 is used. The faucet 3 can discharge hot water from either the outlet pipe 3A, the overhead shower 4, or the hand shower 5. A bather in the bathtub 10 can fill the bath with hot water from the outlet pipe 3A, or from either the overhead shower 4 or the hand shower 5. The bathtub 10 is deformable, so it can be shaped to fit the bather's body. Therefore, the bathtub 10 requires less hot water than a non-deformable bathtub. In the bathtub 10, the inner surface of the bathtub body 30 is the surface of a first layer L1 made of PU film. The surface of this PU film is smooth, making it comfortable to the touch and easy to clean.

[0037] In the bathtub 10, the sheet S1 forming the bathtub body 30 has multiple layers: a first layer L1 and a second layer L2. The first layer L1 is formed of a PU film, which is a water-impermeable material. The second layer L2 is formed of a woven fabric made of PET fiber, which is a durable material. This makes it easy for the bathtub 10 to achieve both hanging strength and waterproofness. For example, if the bathtub were made of a single-layer sheet, the material forming this single layer would need to be both water-impermeable and durable, limiting the materials that can be selected. In contrast, in the bathtub 10, the sheet S1 forming the bathtub body 30 is selected as a PU film to ensure water impermeability and a woven fabric made of PET fiber to ensure durability. In this way, by configuring the sheet S1 forming the bathtub body 30 as a multiple-layer structure, the bathtub 10 allows different materials to be selected separately for water impermeability and durability, and both can be used.

[0038] When filled with hot water, the water pressure of the water acts on each part of the bathtub 10. This water pressure causes each part of the bathtub 10 to deform, and the bathtub body 30 and rope 40 become taut. In particular, the rope 40, which is stretched between the walls W1 and W2 at the upper edge, becomes taut enough that it does not shake significantly even when you place your hand on it. Therefore, while the bathtub 10 is freely deformable, deformation is suppressed by filling it with hot water, and a stable shape is maintained even when bathers enter and exit the bathtub 10.

[0039] The bathtub 10 has joints 31 where sheets S1 are joined together. The joints 31 are joined at heat-sealed sections H1, H2, and H3, where sheets S1 are heat-sealed together using a heat-sealing material H. The joints 31 are joined at three heat-sealed sections H1, H2, and H3 by engaging joint pieces J, which are bent into a U-shaped cross section. This ensures that the bathtub body 30 has sufficient strength and waterproofness at the joints 31.

[0040] The joint 31 extends vertically at the center of the side walls 30C, 30D of the bathtub body 30, which is rectangular in plan view. The bathtub body 30 has a well-defined symmetrical shape on both sides of the joint 31. By positioning the joint 31 so that it extends vertically at the center of the side walls 30C, 30D, the bathtub body 30 can achieve good material yield. In other words, by positioning the joint 31 in this way relative to the bathtub body 30, the bathtub 10 can reduce the unfolded size of the sheet S1 that forms the bathtub body 30 when forming the symmetrical boat-shaped bathtub body 30.

[0041] For example, consider a bathtub body with a shape roughly similar to that of the bathtub body 30. If the joints in this bathtub body are positioned off-center on the side walls of the bathtub body, the shape of the sheet forming the bathtub body in its unfolded state will be asymmetrical. In contrast, in the case of the bathtub body 30, by positioning the joints 31 in the center of the side walls 30C and 30D, the shape of the sheet S1 in its unfolded state can be made symmetrical (see Figure 6). Therefore, compared to a bathtub body with a symmetrical shape formed from an asymmetrical sheet material, the size of the bathtub body 30 in its unfolded state can be reduced, achieving good material yield.

[0042] When filled with hot water, the underside of the center of the bathtub 10 contacts the floor F. By having the underside of the bathtub 10 contact the floor F in this way, the weight of the hot water and the weight of the bather are properly supported by the floor F. This prevents excessive load from being placed on the parts of the bathtub 10 involved in suspending the bathtub 10, such as the second hanging member 20, loop portion 41, rope 40, and insertion portion 32B. The bathroom 1 can simplify the strength of its suspension support structure compared to a structure in which the bathtub is suspended only by its upper edge. Specifically, the strength of the bathroom 1's configuration, such as the second hanging member 20 and the structure of walls W1 and W2, and the bathtub 10's configuration, such as the bathtub body 30 and the rope 40, can be simplified.

[0043] When bathing is finished, the bathtub 10 is drained of the water and removed from the walls W1, W2. When removing the bathtub 10 from the walls W1, W2, it can be removed with the simple action of removing the loop portion 41, which serves as the attachment portion, from the second hanging member 20. Once removed, the bathtub 10 is washed, dried, folded, and stored. Because the bathtub 10 is detachable, the entire interior and exterior surfaces of the bathtub 10 can be cleaned, unlike conventional freestanding bathtubs. Once the water and water have been drained from the bathtub 10, it can be removed from the walls W1, W2 and freely transformed into a folded or rolled-up state. The bathtub 10 can be easily transformed into a shape suitable for storage.

[0044] To drain and dry the bathtub 10, first hanging members 21 are used (see Figures 1 and 3). Each first hanging member 21 is located on the wall W2, above the second hanging members 20, at a height that is within reach of an average adult woman and at a height where the hanging bathtub 10 does not come into contact with the floor F. The bathroom 1 allows the bathtub 10 to be easily dried without having to be taken outside the bathroom 1.

[0045] As shown in Figure 2, bathroom 1 can be suitably used as a shower room where showers can be taken when bathtub 10 is removed. When bathtub 10 is not installed in bathroom 1, the entire floor F can be used as a washing area for showering. Showering can be done in bathroom 1 using at least one of the overhead shower 4 and hand shower 5 in shower device 2. When showering with bathtub 10 removed, neither foam nor water will adhere to bathtub 10. This makes bathroom 1 easy to clean after showering.

[0046] Because bathtub 10 is made of sheet, it is easy to manufacture inexpensively compared to conventional bathtubs made of FRP or the like. Therefore, it is relatively easy to provide a dedicated bathtub 10 for each user. In this case, the size, design, etc. of bathtub 10 can be freely set to suit each user. Compared to conventional freestanding bathtubs made of FRP or the like, bathtub 10 has advantages in terms of transportation costs and recyclability. Therefore, bathtub 10 can reduce the environmental impact. It is relatively easy for one user to own multiple bathtubs 10. In this case, the user can select the desired bathtub from multiple bathtubs 10 depending on their mood, the season, etc., just like choosing clothes.

[0047] <Embodiment 2> A bathroom 101 of embodiment 2, which embodies the bathroom of the present disclosure, will be described with reference to Figure 11. In bathroom 101 of embodiment 2, the spacing between a pair of first hanging members 21 is different from the spacing between the pair of first hanging members 21 in the bathroom of embodiment 1. In other respects, the bathroom of embodiment 2 has the same configuration as bathroom 1 of embodiment 1. In the following description, configurations similar to those of embodiment 1 will be assigned the same symbols, and duplicate explanations will be omitted.

[0048] As shown in Figure 11, the bathroom 101 has a pair of first hanging members 21. Each first hanging member 21 is attached to a wall W2 opposite the wall W1 on which the shower device 2 is located. Each first hanging member 21 is located above the second hanging member 20, at a height that is within reach of an average adult woman, and at a height where the suspended bathtub 10 does not come into contact with the floor F. Specifically, each first hanging member 21 is located at a height of approximately 1700 mm to 1750 mm above the floor F.

[0049] The distance between each of the first hanging members 21 is wider than the distance between the pair of second hanging members 20 provided on the wall W2. Specifically, on the wall W2, the distance between the wall W3 and one of the pair of first hanging members 21 that is provided closer to the wall W3 is the same as the distance between the wall W3 and one of the pair of second hanging members 20 that is provided closer to the wall W3. On the other hand, on the wall W2, the distance between the wall W3 and one of the pair of first hanging members 21 that is provided farther from the wall W3 is wider than the distance between the wall W3 and one of the pair of second hanging members 20 that is provided farther from the wall W3.

[0050] The bathtub 10 can be hooked onto each of the first hanging members 21 by a pair of loops 41 provided at both ends of the folded portion 32 on either the third side wall portion 30C or the fourth side wall portion 30D of the bathtub body 30. In this way, the bathtub 10 can be temporarily hung after use to drain or dry.

[0051] As described above, the bathroom 1,101 of embodiments 1 and 2 is equipped with a first hanging member 21 that can hang the bathtub 10, which has a bathtub body 30 made of sheet S1 and is used to fill with hot and cold water, in a state where it does not come into contact with the floor F. Therefore, in this bathroom 1,101, the bathtub 10, which has a bathtub body 30 made of sheet S1, can be easily drained and dried without having to be taken outside the bathroom 1,101.

[0052] The bathroom 1, 101 of embodiments 1 and 2 is equipped with four second hanging members 20 that can hang the bathtub 30 when filled with hot water and ready for use, and the first hanging members 21 are provided at a higher position than the second hanging members 20. Therefore, in this bathroom 1, 101, the bathtub 10 can be hung by hooking it onto the first hanging members 21 in a state where it does not touch the floor F.

[0053] The bathtub 10 of the first and second embodiments has a loop portion 41 that can be hooked onto both the first hanging member 21 and the second hanging member 20. Therefore, when filling the bathtub 10 with hot water and using it, the loop portion 41 can be hooked onto the second hanging member 20, and after use, the bathtub 10 can be easily drained or dried by hanging it onto the first hanging member 21.

[0054] The bathroom 101 of embodiment 2 is equipped with a pair of first hanging members 21 and four second hanging members 20, and the distance between the pair of first hanging members 21 is wider than the distance between the pair of second hanging members 20 provided on the same wall W2. Therefore, in this bathroom 101, the bathtub 10 can be hung wider apart when hooked on the second hanging members 20, making it easier to drain and dry the bathtub 10.

[0055] In the bathroom 1,101 of embodiments 1 and 2, the first hanging member 21 is provided on the wall W2 opposite the wall W1 on which the shower device 2 is located. Therefore, in this bathroom 1,101, a person can take a shower using the shower device 2 with the bathtub 10 suspended from the first hanging member 21. In this case, bubbles and water are less likely to adhere to the bathtub 10 suspended from the first hanging member 21.

[0056] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments are also included within the technical scope of the present disclosure: In the present disclosure, the various features of the above-described embodiments and the embodiments to be described later may be combined in any manner as long as they are not inconsistent.

[0057] The configuration, size, spatial shape, etc. of the bathroom are not limited to the above embodiments. In the bathroom, it is not essential that the first hanging member be installed on the wall. The first hanging member may be installed on the ceiling of the bathroom. In the bathroom, it is preferable to install a reinforcing structure in the area corresponding to the first hanging part, such as behind the wall or in the ceiling.

[0058] The first hanging member does not have to be installed on the same wall. For example, one hanging member may be installed on each adjacent wall. In this case, the first hanging member can hang the bathtub at the corner of the two walls with a large gap between the wall surface, which is more suitable for draining and drying.

[0059] The wall to which the first suspending member is attached is not particularly limited. That is, the first suspending member may be attached to the wall on which the shower device is provided as exemplified in the above embodiment, or may be attached to a wall that does not face the wall on which the shower device is provided and does not include a shower device. The first suspending member is preferably attached to a wall other than the wall on which the shower device is provided.

[0060] It is not essential that the bathtub be hung vertically from the first hanging member, that is, the bathtub may be hung horizontally from the first hanging member.

[0061] It is not essential that two loops provided on the bathtub be hooked onto each of a pair of first hanging members for hanging. In other words, one loop provided on the bathtub may be hooked onto one first hanging member for hanging.

[0062] The shape, size, configuration, etc. of the bathtub body are not particularly limited as long as they are made of a sheet that is used to fill with hot and cold water while suspended. The shape of the bathtub body is not limited to the shapes exemplified in each embodiment. When viewed from above in use, the bathtub body can be a polygonal shape such as a square, triangle, or pentagon, a circle, an ellipse, etc.
