DETAILED DESCRIPTION <Implementation method 1> Embodiment 1 of the room disclosed in the present invention will be described with reference to the accompanying drawings. In this embodiment, a shower room is exemplified as the room 1. Figure 1 As shown, room 1 is usually a room for taking a shower. Figure 2 As shown, the room 1 can be used as a bathroom for bathing by installing a bathtub 10. That is, the room 1 can be used as a bathroom by installing the bathtub 10, and can be used as a shower room other than a bathroom by removing the bathtub 10. like Figure 1 and Figure 2 As shown in FIG. 1 , the room 1 is in the shape of a rectangular parallelepiped that is long in the longitudinal direction (vertical direction). Figure 3As shown, one of the four sides of room 1 when viewed from above is adjacent to washroom B. Room 1 forms a smaller space than the space of adjacent washroom B. Specifically, when viewed from the side of washroom B, the specific size of room 1 in this embodiment is about 1600 mm in width, about 1200 mm in depth, and about 2200 mm in height. In contrast, washroom B forms a space of about 2000 mm in length connected to room 1 with its width and height being equal to the front width and height of room 1. like Figure 1 and Figure 2 As shown, the room 1 has walls W1, W2, W3, a ceiling C, and a floor F. The room 1 is surrounded by walls W1, W2, W3 on three sides except for the side adjacent to the washroom B when viewed from above. The room 1 is closed by the ceiling C and the floor F at the top and bottom. The upper surface of the floor F extends roughly flush with the floor surface of the washroom B. The upper surface of the floor F is formed roughly flat. There is a slight drainage gradient on the floor F so that hot water flows toward a drain port not shown. The walls W1, W2 are connected roughly flush with the walls of the washroom B. like Figures 1 to 3 As shown, the room 1 is provided with a partition P. The partition P is opened and closed freely to partition the room 1 from the washroom B. The partition P can open substantially the entire front of the room 1. By opening the partition P, the room 1 and the washroom B form a single rectangular space in a top view that is connected to each other. like Figures 1 to 3 As shown, room 1 is equipped with a shower device 2. Shower device 2 is arranged on wall W1 among walls W1, W2, and W3. Shower device 2 is arranged at a position near wall W3 in wall W1. Shower device 2 has a faucet 3, an overhead shower 4, and a hand shower 5. Faucet 3 is formed into a long cylindrical shape extending in the horizontal direction along the wall surface of wall W1. Faucet 3 is connected to a cold water pipe and a hot water pipe (not shown) in wall W1. Faucet 3 is a mixing faucet. Faucet 3 can adjust the amount of water, adjust the temperature of mixing hot water and cold water, spray water and turn off the water, etc. In this specification, hot water and cold water supplied from the faucet arranged in the room are expressed as bath water regardless of the temperature, mixing ratio, etc. like Figure 4 As shown, the faucet 3 is formed with a water spout 3A. The water spout 3A is formed in a long slit shape along the axial direction of the faucet 3. The water jet sprayed from the water spout 3A is in a horizontally long film shape. When the bathtub 10 described later is installed in the room 1, the faucet 3 can spray bath water from the water spout 3A into the bathtub 10. The faucet 3 can select any one of the water spout 3A, the overhead shower 4 and the hand shower 5 to spray bath water. like Figure 1 and Figure 2As shown, the overhead shower 4 is arranged above the faucet 3. The overhead shower 4 is connected to the faucet 3 via a pipe 6. The pipe 6 extends vertically upward from the faucet 3 along the wall surface of the wall W1 and bends toward the inside of the room 1 at the upper end. The overhead shower 4 is arranged at the front end of the pipe 6. The hand shower 5 is connected to the faucet 3 via a hose 7. The hand shower 5 can be freely moved within the length range of the hose 7 for use. A bathtub 10 described later is installed on the walls W1, W2, and W3 in the room 1. In the present embodiment, the bathtub 10 is installed on a pair of walls W1 and W2 located on the left and right sides of the three walls W1, W2, and W3 as viewed from the wash basin B. The bathtub 10 is arranged closer to the wall W3 than the partition P (wash basin B). Figure 3 As shown, in a state where the bathtub 10 is attached to a pair of walls W1 and W2 , a space that can be used as a bathing place is formed on the partition portion P side viewed from the bathtub 10 . The pair of walls W1 and W2 each have a mounting member 20. The mounting member 20 is mounted by hooking a portion of the bathtub 10. In the present embodiment, the mounting member 20 is in the form of a J-shaped hook opened upward in a side view and is fixed to each wall W1 and W2. Figure 4 As shown, two mounting parts 20 on the wall W1 side are arranged at intervals in the horizontal direction below the faucet 3. Two mounting parts 20 on the wall W2 side are provided at the same height and the same interval as the mounting parts 20 on the wall W1 side. That is, in the case of this embodiment, two mounting parts 20 are provided on each side of a pair of walls W1 and W2, and a total of four mounting parts are provided. The bathtub 10 is installed on a mounting portion 21 corresponding to the hook-shaped portion of the mounting part 20. The mounting part 21 is detachably mounted on the bathtub 10, and the bathtub side mounting part 10A described later is installed. The bathtub 10 is detachably mounted on a pair of walls W1, W2 that are opposite to each other among the walls W1, W2, and W3. Figure 5 As shown, the bathtub 10 has a bathtub side mounting portion 10A. The bathtub side mounting portion 10A is detachably mounted on a mounting component 20 provided on the walls W1, W2. The bathtub side mounting portion 10A corresponds to a portion of the bathtub disclosed in the present invention, and is mounted by being hooked on the mounting component 20. The bathtub side mounting portion 10A is provided at the upper edge of the bathtub 10. That is, the bathtub 10 is in a form suspended from the mounting component 20 at the upper edge. The bathtub 10 is deformed in order to hold bath water. The bathtub 10 can freely change its shape to a folded state, an unfolded state, etc. The bathtub 10 of the present embodiment is configured to include a basin body 11 and a rope 12. The basin body 11 holds bath water. The basin body 11 is made of a sheet. The basin body 11 is flexible. The basin body 11 is formed into a rectangular boat shape when viewed from above by cutting and joining a soft waterproof sheet. The basin body 11 of the present embodiment lacks elasticity and maintains a boat shape to a certain extent when bath water is stored therein. The rope is arranged in a ring shape along the upper edge of the basin body 11. When the bathtub 10 is set, the basin body 11 is in a state where the outer edge is suspended from the rope 12. The rope 12 constitutes the bathtub side mounting portion 10A. The rope 12 also functions as a reinforcing portion for reinforcing the basin body 11. Thus, the basin body 11 is in the shape of a boat with the outer edge forming an upper edge and the central portion being recessed downward. When filled with bath water, the central lower surface of the basin body 11 contacts the floor F of the room 1. Thus, the bathtub 10 can support most of the load on the floor F when filled with bath water. Therefore, compared with the case where the bathtub 10 is supported only by the wall, the reinforcement structure of the walls W1 and W2 can be simplified. like Figure 6 As shown, the rope 12 is inserted into the bending portion 11A of the upper edge of the basin body 11. The bending portion 11A is formed by bending the outer edge of the basin body 11 into a cylindrical shape. The bending portion 11A is formed over the entire circumference of the upper edge of the basin body 11. The bending portion 11A is divided at the four corners of the bathtub 10 which is rectangular when viewed from above. The rope 12 is exposed to the outside at the four corners of the basin body 11. The bathtub 10 is installed and detached relative to the walls W1, W2 by hooking the rope 12 exposed from the basin body 11 on the hook-shaped mounting portion 21. The bending portion 11A is bent into a double structure, and therefore also functions as a reinforcement portion of the upper edge of the basin body 11. like Figure 5 As shown, the bathtub 10 of this embodiment has a drain portion 13. The drain portion 13 is formed by providing an opening that can be opened and closed by a waterproof sliding zipper at the lower part of the bathtub body 11. Thus, the bathtub 10 can easily drain the bath water contained therein to the outside of the bathtub 10. The function and effect of the room 1 of the above structure are described. The room 1 is in a normal state, that is, a state where the bathtub 10 is not installed (a state where the bathtub 10 is removed). Figure 1 As shown, it is possible to take a shower using the entire floor F as a bathing place. Room 1 can take a shower using at least one of the overhead shower head 4 and the hand shower head 5 in the shower device 2. Room 1 can enjoy a leisurely shower in a larger space than conventional general shower rooms or bathing places, such as 1600 mm in width and 1200 mm in depth. When taking a shower in a state where the bathtub 10 is removed, room 1 will not have foam or bath water attached to the bathtub 10. Therefore, room 1 is easy to clean after taking a shower. Room 1 is not only for daily showers, but also for bathing as an extra-daily pleasure. When taking a bath in Room 1, Figure 2 As shown, the bathtub 10 is mounted on the walls W1, W2. The bathtub 10 is detachably mounted on the walls W1, W2. The bathtub 10 is made of a sheet material that can be flexibly deformed into a folded state and an unfolded state. Therefore, the bathtub 10 can be installed and stored very easily. When installing, the bathtub 10 can be installed by a simple method such as installing the ropes 12 exposed at the four corners as the bathtub side installation part 10A to the installation part 21 of the wall W1, W2. When the bathtub 10 is set, the faucet 3 of the shower device 2 is used to fill the bathtub 10 with bath water. Figure 4 As shown, the faucet 3 can spray a thin film of bath water from the water spout 3A. When taking a bath using the bathtub 10, the user can pour the thin film of bath water sprayed from the water spout 3A onto the neck or shoulders in the bathtub 10. The user can pour the bath water from the water spout 3A while keeping the bath water in the bathtub 10. Since the bathtub 10 is deformable, it can be formed into a shape that suits the user's body. Therefore, the bathtub 10 only needs to hold a smaller amount of bath water than a bathtub that cannot be deformed. When the bathtub 10 is filled with bath water, a force generated by the water pressure of the bath water acts on various parts of the bathtub 10. Due to the action of this water pressure, various parts of the bathtub 10 are deformed, and the body 11 and the rope 12 are in a tensioned state. In particular, the rope 12 constituting the upper edge of the bathtub 10 is firmly tensioned to such an extent that it will not shake much even if the user puts his hand on it. Therefore, the bathtub 10 can be deformed freely, and deformation is suppressed by holding bath water, and a stable shape can be maintained even when the user enters and exits the bathtub 10. When the bathtub 10 is filled with bath water, the lower surface of the central portion is in contact with the ground F. By making the lower surface of the bathtub 10 in contact with the ground F in this way, the weight of the bath water in the bathtub 10 and the weight of the user are appropriately supported by the ground F. As a result, an excessive load on the mounting portion 21 is suppressed. Therefore, the room 1 can simplify the reinforcement structure of the wall W1, W2 side provided with the mounting portion 21, compared with a structure in which the bathtub is supported only by a wall or a ceiling. After the bath is finished, the bath water in the bathtub 10 is drained from the drain 13, and the bathtub 10 is removed from the walls W1, W2. Specifically, in the case of the present embodiment, the zipper in the drain 13 is opened to drain the bath water, and the rope 12 serving as the bathtub side mounting portion 10A is removed from the mounting portion 21. The removed bathtub 10 is washed, dried, folded, and stored. Since the bathtub 10 is freely disassembled, the entire inner and outer surfaces of the bathtub 10 can be washed, unlike conventional fixed bathtubs. The bathtub 10 is made of a soft and deformable sheet material, so it can be washed, dried, and folded like washing clothes. After the bathtub 10 is removed, the room 1 presents a flat floor F. Therefore, the floor F of the room 1 is easy to clean and easy to keep clean. Since the bathtub 10 is soft and deformable, for example, by arranging a chair or bench, a cushion, etc. between the bathtub 10 and the floor F, it is also possible to take a bath in a desired posture. A massage device or a heater may be disposed between the bathtub 10 and the floor F. Since these devices are disposed outside the bathtub 10 , waterproofness is not required. The bathtub 10 is made of a soft sheet material, and therefore is easy to manufacture at a low cost compared to conventional bathtubs such as those made of FRP. Therefore, it is also relatively easy to set up a dedicated bathtub for each user with the bathtub 10. In this case, the size and design of the bathtub 10 can be freely set according to each user. The bathtub 10 is advantageous in terms of transportation cost or reusability compared to conventional fixed bathtubs such as those made of FRP. Therefore, the bathtub 10 can achieve a reduction in environmental load. It is also relatively easy for one user to own a plurality of such bathtubs 10. In this case, the user can select a desired bathtub from a plurality of bathtubs 10 to use according to mood, season, etc., just like choosing a suit. Since the bathtub 10 can be easily assembled and disassembled, it can also contribute to barrier-free operation. For example, the bathtub 10 before being installed on the mounting component 20 is placed on the ground F. In this state, the user sits on the bathtub 10. After that, by installing the bathtub side mounting portion 10A of the bathtub 10 on the mounting component 20 and filling it with bath water, it is possible to take a bath without crossing the upper edge of the bathtub 10. According to this bathing method, users who find it difficult to cross the upper edge of the bathtub 10 and users sitting in wheelchairs can also easily take a bath. like Figure 7 As shown, by opening the partition P, the room 1 can form a space connected to the washroom B. The space thus formed is larger than the space formed by only the room 1. The space thus formed can be used for various purposes such as a gym, a laundry room, etc., where a larger space is required. As described above, the room 1 of the first embodiment includes walls W1, W2, W3 and a ceiling C. The room 1 can freely attach and detach a bathtub 10 to the walls W1, W2 of the walls W1, W2, W3 and the ceiling C. The room 1 is used as a bathroom by attaching the bathtub 10. The room 1 is used as a shower room other than a bathroom by removing the bathtub 10. Room 1 is a room for showering, but can also be used as a room for bathing, i.e., a bathroom, by installing a bathtub 10. When taking a shower, room 1 can form a large space by removing the bathtub 10. That is, room 1 is installed with the bathtub 10 only when the bathtub 10 is needed, and when the bathtub 10 is not needed, the space can be efficiently utilized accordingly because there is no bathtub 10. Preferably, room 1 is a space that has been waterproofed by using a waterproof mat on the floor. In this case, in addition to the shower room, the waterproof space can also be used for the care of foliage plants or hot yoga, etc. The room 1 is provided with a freely openable and closable partition P between the room 1 and the adjacent other room, namely, the washroom B. The room 1 is used as a single space together with the washroom B by opening the partition P. Thus, the room 1 can constitute a space larger than the space of the room 1 alone. Therefore, the room 1 can also be used for further different purposes requiring a larger space, and has excellent versatility. The bathtub 10 according to the first embodiment can be appropriately installed in the room 1 . <Implementation method 2> The room of Embodiment 2 is described with reference to the accompanying drawings. The room 201 of Embodiment 2 is generally a shower room for taking a shower, which is the same as that of Embodiment 1. The room 201 is different from the room 1 of Embodiment 1 in the structure for installing the bathtub 10. In the following description, the same figure mark is attached to the same structure as that of Embodiment 1, and repeated description is omitted. like Figure 8 As shown in FIG. 2 , the room 201 of the second embodiment has a faucet 203 and a mounting member 220 as mounting members. The faucet 203 is mounted on the wall W1. Fig. 9 As shown in the figure, the faucet 203 has the same structure as the faucet 3 of the first embodiment except that it has a mounting portion 221. That is, the faucet 203 is formed with a long slit-shaped water spout 3A along the axial direction of the faucet 203, and sprays a horizontally long thin film-shaped water spray flow. The mounting portion 221 is provided at both ends of the long side direction of the faucet 203. The mounting portion 221 is a form in which the peripheral wall of the cylindrical faucet 203 is reduced in diameter in a groove shape. The mounting portions 221 at both ends of the faucet 203 are in a form in which the water spout 3A is sandwiched therebetween. The mounting component 220 is mounted on the wall W2. Fig.10As shown, the mounting member 220 is in a shape imitating the faucet 3. Specifically, the mounting member 220 is formed into a long cylindrical shape extending in the horizontal direction along the wall surface of the wall W2. The mounting portion 221 of the mounting member 220 is the same structure as the mounting portion 221 of the faucet 203. That is, the mounting portion 221 of the mounting member 220 is provided at both ends in the long side direction of the mounting member 220, and is a form in which the peripheral wall of the mounting member 220 is grooved and reduced in diameter in the circumferential direction. The mounting member 220 can also be used as a handrail when entering the bathtub. The room 201 of the second embodiment of the above-mentioned structure is the same as the first embodiment. When taking a bath, the bathtub 10 is installed only when necessary. When the bathtub 10 is not used, the bathtub 10 is not used, so the space can be efficiently used accordingly. By providing the faucet 203 as a mounting component on the wall W1 side, the room 201 can reduce the number of components that function only as mounting components. Therefore, the room 201 as a whole can achieve a simple design. By setting the mounting component 220 on the wall W2 side to imitate the shape of the faucet 203, the appearance of the two mounting components is coordinated, and a simple and beautiful appearance can be achieved. <Implementation method 3> like Fig.11 As shown, the room 301 of the third embodiment is different from the above embodiments in that the bathtub 10 is suspended from the ceiling C. In the following description, the same reference numerals are given to the same structures as those in the above embodiments, and repeated descriptions are omitted. like Fig.11 As shown, room 301 is the same as Embodiment 2 in that faucet 203 is provided as a mounting member on the wall W1 side. Room 301 is different from Embodiment 2 in that another mounting member 320 is provided on ceiling C instead of wall W2. That is, in this embodiment, bathtub 10 is in a form that can be freely attached to wall W1 and ceiling C. The mounting member 320 is formed into a long cylindrical shape similarly to the mounting member 220 of the second embodiment. The mounting portion 321 is also formed into a groove shape at both ends in the long side direction of the mounting member 320. The mounting member 320 is connected to the lower end of a rope 322 suspended from the ceiling C. The upper end of the rope 322 is connected to a reinforcing structural member or a building member (not shown) on the ceiling or the back of the ceiling to ensure sufficient strength to suspend the bathtub 10. The room 301 of the third embodiment of the above structure is the same as the first embodiment, and the bathtub 10 is installed only when the bathtub 10 is needed. When the bathtub 10 is not used, the bathtub 10 is not provided, so the space can be efficiently used accordingly. The room 301 can realize a simple design by providing the mounting portion 221 on the faucet 203. In the room 301, the bathtub 10 is suspended from the mounting member 320 provided on the ceiling C. Therefore, when the room 301 is provided with the bathtub 10 and used as a bathroom, the unusual feeling of the suspended bathtub can be expressed. In the case of a structure in which the bathtub 10 is installed on a wall and a ceiling as in room 301, the degree of freedom of the installation direction of the bathtub can be increased compared to a case in which it is installed only on a wall. For example, as in the above-mentioned embodiments, when the bathtub is installed relative to a pair of opposing walls, the pair of walls need to be opposed to each other with an appropriate interval. In contrast, in the case of a bathtub installed on a wall and a ceiling, it can be installed regardless of the interval between the walls. For example, in the case of a structure in which the bathtub is installed on a wall and a ceiling, the bathtub can also be installed on a wall without an opposing wall, such as wall W3 in room 301. <Implementation method 4> like Fig.12 As shown, the room 401 of the fourth embodiment is different from the third embodiment in that the bathtub 10 is suspended from the ceiling C as a whole by a mounting component 420, and is the same as the third embodiment in other respects. The mounting component 420 is formed into a long cylindrical shape that is longer than the mounting component 320 of the third embodiment, and is provided with mounting portions 421 at both ends. In the present embodiment, the bathtub side mounting portions 10A at four locations of the bathtub 10 are all mounted on any one of the mounting portions 421 at both ends of the mounting component 420. In the room 401, the bathtub 10 is configured not to contact the ground F even when filled with bath water. The mounting component 420 is connected to the ceiling C by a rope 422. The rope 422 is branched into two strands at the lower end and connected to both ends of the mounting component 420. As a result, the mounting component 420 has improved stability against tilting compared to the mounting component 320 of the third embodiment. In the room 401 of the fourth embodiment of the above structure, the bathtub 10 is installed in the same manner as in the first embodiment, only when the bathtub 10 is needed. When the bathtub 10 is not used, the bathtub 10 is not present, so that the space can be efficiently utilized. Since the bathtub 10 is suspended and installed in the room 401 using only one mounting member 420, a room with a simple exterior design can be realized. In the room 401, the bathtub 10 does not come into contact with the ground F even when it is filled with bath water. Therefore, in the bathtub in the room 401, the user can take a bath with a floating feeling that has never been felt before. <Implementation method 5> like Fig.13 As shown, the room 501 of the fifth embodiment is different from the above embodiments in that the bathtub 10 is mounted on a mounting member 520 disposed on the floor F. In the following description, the same reference numerals are given to the same structures as those in the above embodiments, and repeated descriptions are omitted. like Fig.13 As shown, room 501 is provided with faucet 203 and mounting part 520 as mounting parts.

In the case where the bathtub has a reinforcement part, the structure of the reinforcement part is not limited to the above-mentioned embodiments. The reinforcement part is not limited to the flexible parts such as ropes exemplified in the above-mentioned embodiments, and can also be a resin or metal cylindrical body, rod-shaped body, linear body, plate, etc., which lacks flexibility and has excellent rigidity. The structure of the bathtub side mounting part disclosed in the present invention is not limited to the above-mentioned embodiments. The bathtub side mounting part may be composed of a part of the basin body, or may be composed of a component different from the basin body, such as a rope. In addition to the ring shape and the cylindrical shape exemplified in the above-mentioned embodiments, the bathtub side mounting part may also be in various forms such as a hook shape and a bag shape. The bathtub side mounting part may also be in a form that is mounted to the mounting component via other components such as a rope. The number of bathtub side mounting parts is not limited to the above-mentioned embodiments. For example, the bathtub side mounting parts may be provided in three or more places. In this case, the bathtub can be stably installed. The number and structure of the mounting parts disclosed in the present invention are not limited to the above-mentioned embodiments. For example, the number of mounting parts may be greater than the number of mounting parts on the bathtub side. In this case, when installing the bathtub, the configuration and shape of the bathtub can be selectively changed by selecting a few mounting parts from a plurality of mounting parts to install the bathtub side mounting parts according to the user's preferences. The mounting part is not limited to the hook shape, groove shape, etc. illustrated in the above-mentioned embodiments, and various forms such as a rod shape, a ring shape, etc. may be used. The mounting component of the present disclosure may also be, for example, Fig.15 As shown in the form. Fig.15 In the embodiment, the mounting member 620 has a mounting portion 621. The mounting portion 621 is disposed between the two ends of the mounting member 620 in the shape of a long cylinder. Fig.15 As shown, the mounting member 620 can be detachably supported by two ring-shaped ropes 622 at the groove-shaped portions formed at both ends in the longitudinal direction. Fig.15 As shown, two looped ropes 622 can be suspended from a suspension member 623. The suspension member 623 is configured as a ring having a ring at the lower end of a rod-shaped portion suspended from the ceiling C. The upper end of the suspension member 623 is connected to a reinforcement structure or a building member (not shown) on the ceiling or the back of the ceiling. The suspension member 623 is not limited to being installed on the ceiling, and can also be installed on a wall, for example. With respect to the mounting member 620 of the above structure, the bathtub can have Fig.15 The tub side mounting portion 610A is mounted on the mounting portion 621 as shown. The tub side mounting portion 610A is formed by bending the end of the long side direction of the tub 610 to form a cylindrical shape. The tub side mounting portion 610A is mounted on the mounting portion 621 by allowing the mounting member 620 to penetrate axially from one end side. The mounting member 620 also functions as a reinforcement member for strengthening the tub 610. The mounting component of the present disclosure may also be, for example, Fig.16 As shown in the form. Fig.16 In the embodiment, the mounting member 720 has a mounting portion 721. The mounting portion 721 is provided between the two ends of the mounting member 720 in the shape of a long cylinder, similarly to the mounting portion 621 described above. The mounting member 720 is supported by supporting portions 722 provided on a pair of opposing walls, for example, at groove-shaped portions formed at the two ends in the longitudinal direction. Fig.17 As shown, the support portion 722 is in the shape of a rectangular box that opens upward, and has a cutout portion formed on one side for inserting the end of the mounting member 720. The mounting member 720 is installed between a pair of walls with both ends supported by the support portion 722. In this state, the mounting member 720 is arranged along the long side direction of the bathtub 710. With respect to the mounting component 720 of the above-mentioned structure, the bathtub 710 can be mounted on the mounting portion 721 at the end in the short side direction, that is, the long side when viewed from above. The bathtub 710 has a bathtub side mounting portion 710A. The bathtub side mounting portion 710A is formed by bending the end in the short side direction of the bathtub 710 into a cylindrical shape. The bathtub side mounting portion 710A is mounted on the mounting portion 721 by allowing the mounting component 720 to pass axially from one end. Such a mounting component 720 also functions as a reinforcement for strengthening the bathtub 710. The mounting component of the present disclosure may also be, for example, Fig.18 As shown in the form. Fig.18 In the figure, the mounting component 820 has a mounting portion 821. The mounting portion 821 is disposed between the two ends of the cylindrical mounting component 820. The mounting component 820 can be supported on the guide rail component 822 at the two ends in the long side direction, for example. The guide rail component 822 is a channel-shaped steel component having a roughly U-shaped cross-section. The guide rail component 822 is extended in the up-down direction along the wall surface. The guide rail component 822 is formed with a plurality of holes 822A arranged in the up-down direction. The mounting component 820 is selectively inserted into the hole 822A. The user selects a plurality of holes 822A of a desired height so that the bathtub 810 becomes a desired height and inserts the mounting component 820. like Fig.18 With Fig.19 As shown, the mounting member 820 can be formed by bending both ends 820A into an L shape. The hole 822A is formed to a size that allows the mounting member 820 to be inserted. By combining the mounting member 820 and the hole 822A, it is possible to impart a function of preventing the mounting member 820 from falling out of the hole 822A. The hole 822A can be formed, for example, Fig.19 Thus, when the mounting member 820 is removed, the directional restriction about the axis with respect to the hole 822A is generated, so that a more reliable anti-drop function can be provided. With respect to the mounting member 820 of the above structure, the bathtub 810 is Fig.18 and Fig.19 The bathtub side mounting portion 810A shown is mounted on the mounting component 820. The bathtub side mounting portion 810A is formed by bending in a cylindrical manner at the four corners of the bathtub 810. When installing the bathtub 810, it is arranged in the groove of the rail component 822 at a height position matching the desired hole 822A, and in this state, the mounting component 820 is inserted from the side of the rail component 822 in the order of hole 822A, bathtub side mounting portion 810A, and hole 822A. As a guide rail component, for example, Fig. 20 and Fig.21 The form shown. Fig. 20 and Fig.21 The rail member 922 shown has a plurality of holes 922A formed in the vertical direction similarly to the rail member 822. The plurality of holes 922A have a substantially circular inner peripheral shape. The plurality of holes 922A are connected in the vertical direction by slits 922B. The slits 922B are formed with a width smaller than the inner diameter of the holes 922A. For such a track member 922, as Fig.21As shown, the mounting component 920 is cylindrical and is inserted into any hole 922A in the rail component 922. The mounting portion 921 of the mounting component 920 corresponds to the portion between the two ends. The mounting component 920 has an outer diameter equal to the inner diameter of the hole 922A and can be freely inserted into the hole 922A. The two ends 920A of the mounting component 920 are formed with two-sided widths equal to the width of the slit 922B. Thus, the mounting component 920 can be installed in the desired hole 922A by moving the rail component 922 in the up-and-down direction via the slit 922B without being disassembled from the rail component 922. Therefore, the bathtub side mounting portion 810A can change the height position while being mounted on the mounting portion 921. In this case, not only can the bathtub be easily changed to a desired height position, but it is also effective when, for example, the bath water in the bathtub is drained. That is, according to the above-mentioned structure, the bath water in the bathtub can be easily drained without providing a drain portion in the bathtub, simply by lowering the height of one portion of the bathtub-side mounting portion 810A. The mounting components of the present disclosure may also be Fig. 22 and Fig.23 The structure setup shown. Fig. 22 and Fig.23 The mounting portion 1021 shown is composed of a first rod-shaped member 1020A and a second rod-shaped member 1020B as mounting members. The first rod-shaped member 1020A and the second rod-shaped member 1020B are arranged in a vertical direction in a manner parallel to the wall surface and extending in the horizontal direction. The first rod-shaped member 1020A is fixedly mounted on the wall. The second rod-shaped member 1020B is arranged above the first rod-shaped member 1020A so as to be freely movable in parallel with the first rod-shaped member 1020A in the vertical direction. Fig. 22 The bathtub 1010 shown is installed on the installation portion 1021 at the bathtub side installation portion 1010A. In detail, the bathtub side installation portion 1010A is installed on the installation portion 1021 by being rolled into an S shape and sandwiched by two rod-shaped parts 1020A and 1020B from the upper and lower directions. In this case, the weight of the bathtub acts in a direction that increases the strength of the bathtub side installation portion 1010A sandwiched by the two rod-shaped parts 1020A and 1020B, thereby enabling a more secure installation. Fig.23 As shown in FIG. 1 , a bent portion 1011A is formed at the end of the bathtub side mounting portion 1010A. In the bathtub side mounting portion 1010A, the bent portion 1011A functions as a stopper to prevent the mounting portion 1021 from falling off. The mounting component of the present disclosure may also be, for example, Fig.24 and Fig.25 As shown in the form. Fig.24 and Fig.25In the embodiment, the mounting member 1120 has a mounting portion 1121. The mounting portion 1121 is a ring-shaped portion of the mounting member 1120. The tub side mounting portion may also be, for example, Fig.25 The bathtub side mounting part 1110A is a bathtub side mounting part 1110A which is formed by extending a portion of the upper end of the bathtub 1110 outward and forming a bag shape at the extended end. Fig.25 The spherical body 1110B is shown. The spherical body 1110B has an outer diameter larger than the maximum inner diameter of the mounting portion 1121, and has a certain degree of rigidity. When the bathtub side mounting portion 1110A is mounted on the mounting portion 1121, after the bathtub side mounting portion 1110A passes through the annular mounting portion 1121, the spherical body 1110B is placed in the bag-shaped portion at the front end. As a result, the spherical body 1110B is hooked on the mounting portion 1121 to prevent it from falling off, thereby maintaining the state in which the bathtub side mounting portion 1110A is mounted on the mounting portion 1121. The annular mounting portion described above can be mounted with various types of tub side mounting portions. For example, Fig.26 and Fig. 27 The bathtub side mounting portion 1210A shown has the same structure as the bathtub side mounting portion 1110A described above, except that the front end is not formed into a bag shape. After the bathtub side mounting portion 1210A passes through the annular mounting portion 1121, the front end is connected to the ring 1210B. Like the spherical body 1110B, the ring 1210B has an outer diameter larger than the maximum inner diameter of the mounting portion 1121 and has a certain degree of rigidity, so that the bathtub side mounting portion 1210A can be maintained in a state of being mounted on the mounting portion 1121. Such a bathtub side mounting portion 1210A can be installed only by connecting it to, for example, an annular mounting portion or a hook-shaped mounting portion such as the mounting portion 1121. In this case, the shape of the bathtub can be adjusted only by changing the fastening method. The mounting part may also be, for example, Fig.28 The form shown. Fig.28 In the embodiment, the mounting component 1320 is a structure that can be detachably mounted on a desired position of a wall by magnetic force. The mounting component 1320 is connected to a support component 1322 so as to be rotatable around an axis extending in a substantially horizontal direction. The support component 1322 is axially supported on the mounting component 1320 at the upper end. The support component 1322 is in the shape of a rod extending downward from the mounting component 1320, and a ground support portion 1322A provided at the lower end is in contact with the ground F. Even when the angle of the support component 1322 relative to the mounting component 1320 is changed according to the height position of the mounting component 1320, the ground support portion 1322A can be maintained in a state of being in contact with the ground F. With respect to such a mounting component 1320, the mounting portion is not limited to Fig.28The annular form shown can be provided in the various forms described above. The ground support portion 1322A may be provided with an anti-slip structure relative to the ground F. As the anti-slip structure, for example, a structure in which a suction cup adsorbed to the ground F is provided, a structure in which a sheet of rubber or elastic material is provided on the contact surface with the ground F, etc. As the anti-slip structure, for example, Fig.28 As shown, a plate-shaped anti-skid component F1 may be laid on the ground F, and the ground support portion 1322A may contact the end of the anti-skid component F1. In this case, the anti-skid component F1 may contact the central lower surface of the bathtub when the bath water is filled. Thus, the positional deviation of the anti-skid component F1 itself can be suppressed, and the positional deviation of the ground support portion 1322A in the support member 1322 and the mounting member 1320 connected thereto can be effectively prevented. As a bathtub side mounting portion, for example, Fig.29 and Fig.30 The form shown. Fig.29 and Fig.30 The tub side mounting portion 1410A shown is a form formed by a portion of the tub body 1411. Specifically, the tub side mounting portion 1410A forms a hole at the outer edge of the tub body 1411 of the tub 1410, and the peripheral edge of the hole is reinforced by the eyelet 1414. The tub body 1411 is reinforced by bending and overlapping the portion where the tub side mounting portion 1410A is provided. Fig.29 and Fig.30 As shown, such a bathtub side mounting portion 1410A can be mounted on the same hook-shaped mounting member 20 as in the above-mentioned first embodiment. As the tub side mounting portion, for example, Fig.31 and Fig.32 The form shown. Fig.31 The bathtub side mounting portion 1510A shown is a bathtub side mounting component 1514 provided in the bathtub 1510 and mounted on the outer edge of the bathtub body 1511. The bathtub side mounting component 1514 can be formed as an integral molded part, for example, from resin or the like. Fig.32As shown, the bathtub side mounting component 1514 has an annular portion 1514A and a retaining portion 1514B. The annular portion 1514A constitutes the bathtub side mounting portion 1510A. The annular portion 1514A is annular and can be mounted on a hook-shaped mounting component. The retaining portion 1514B is connected to the annular portion 1514A to retain the outer edge of the basin body 1511. The retaining portion 1514B clamps and retains the outer edge of the basin body 1511 by forming a plate-like component with a plurality of protrusions and other plate-like components with holes for the plurality of protrusions to fit. The two plate-like components in the retaining portion 1514B are connected, for example, at one end, and can be opened and closed in a hinge-like manner by elastic deformation. The outer edge of the basin body 1511 is reinforced by bending and overlapping the portion where the bathtub side mounting component 1514 is mounted. The bathtub side mounting member 1514 may include, for example, a member constituting another type of bathtub side mounting portion such as a hook-shaped portion instead of the annular portion 1514A. As the tub side mounting portion, for example, Fig.33 and Fig.34 The form shown. Fig.33 and Fig.34 The bathtub side mounting portion 1610A shown in the figure is a bathtub side mounting member 1614 installed on the outer edge of the bathtub body 1611 in the bathtub 1610. Fig.33 and Fig.34 As shown, the bathtub side mounting component 1614 is in the shape of a long bar, and is fixed to the basin body 1611 in an irremovable manner by wrapping around the outer edge of the basin body 1611. Both ends of the bathtub side mounting component 1614 protrude and are exposed from the outer edge of the basin body 1611. The bathtub side mounting portion 1610A is provided at the portions of the bathtub side mounting component 1614 that are exposed from the basin body 1611 at both ends. The bathtub side mounting portion 1610A is in the shape of a groove, and can be mounted on a hook-shaped, ring-shaped, or other mounting component. The bathtub of the present invention does not necessarily have a drain. In the case where the bathtub has a drain, the structure of the drain is not limited to the above-mentioned embodiments. The drain can be a drain having various known plugs, such as a resin plug used for a life buoy, a rubber plug used in a conventional bathtub, and a plug for a kettle. As the drainage part, for example, Fig.35 The form shown. Fig.35The drain portion 1713 shown is provided in the bathtub 1710. The bathtub 1710 is different from the above-mentioned embodiments in that the upper edge portion is constituted only by the basin body 1711. That is, the bathtub 1710 is in the form of a ring-shaped rope along the upper edge portion of the basin body 1711. The drain portion 1713 is configured to have a waterproof sliding zipper similar to the above-mentioned embodiments. The zipper in the drain portion 1713 is provided on the upper portion of the basin body 1711. The drain portion 1713 can be opened by disconnecting the upper edge portion of the basin body 1711 by sliding the zipper downward. like Fig.35 As shown, the lower end of the zipper in the drain portion 1713 is set at a position slightly higher than the assumed water surface height in the bathtub 1710. That is, the drain portion 1713 will not be submerged in water when a normal amount of bath water is placed in the bathtub 1710. Therefore, the drain portion 1713 can prevent the bath water from leaking out regardless of the waterproofness of the zipper. When the zipper of the basin body 1711 is opened, the outer circumference of the upper edge portion becomes larger and loosens. Therefore, the bathtub 1710 can drain a certain amount of bath water through the drain portion 1713. The bathtub 170 is removed and the bath water remaining in the bathtub 1710 is drained. The bathtub 1710 that has drained a certain amount of bath water using the drain portion 1713 is lighter than before the drain, and is therefore easy to disassemble. As described above, the bathtub 1710 is in the form of a looped rope that does not extend along the upper edge portion of the basin body 1711. As another solution, the bathtub 1710 may be provided with ropes only on the long sides of the bathtub body 1711 for purposes of reinforcement, bathtub side mounting, etc., and the zipper may be provided on the upper part of the short sides where no ropes are provided. As the drainage part, for example, Fig.36 The form shown. Fig.36 The drain portion 1813 shown is integrally provided on the basin body 1811. The inner surface of the drain portion 1813 is tightly fitted by an adhesive material or the like, and is blocked in a manner that water is not easily discharged from the pipe. When bath water is contained in the bathtub 1810, the drain portion 1813 is further pressurized by water pressure and blocked, thereby preventing the bath water from being discharged. The drain portion 1813 is opened by overcoming the water pressure, so that the bath water in the bathtub 1810 can be discharged to the outside. As the drainage part, for example, Fig.37 The form shown. Fig.37The drain portion 1913 shown is integrally provided on the basin body 1911. The drain portion 1913 is formed in a tubular shape protruding to the outside of the bathtub 1910. The tubular drain portion 1913 is flexible. The drain portion 1913 is formed with a length that allows its front end to be arranged above the water surface height when bath water is contained in the bathtub 1910. By arranging the front end portion above the water surface, the drain portion 1913 can prevent the bath water from being discharged and can maintain the state in which bath water is contained in the bathtub 1910. By arranging the front end portion below the water surface, the drain portion 1913 can easily discharge the bath water in the bathtub 1910. As the drainage part, for example, Fig.38 The form shown. Fig.38 The drain portion 2013 shown is provided in the bathtub 2010. The drain portion 2013 is in a form in which an opening 2013A formed at the bottom of the basin body 2011 is closed by a float valve 2013B. The float valve 2013B can close the opening 2013A by water pressure when bath water is contained in the bathtub 2010. The float valve 2013B is connected to an operating rod 2013C installed on the wall via a bead chain. The float valve 2013B opens the opening 2013A by operating the operating rod 2013C. The float valve 2013B in the state of opening the opening 2013A maintains this state by buoyancy. When the bath water in the bathtub 2010 is drained, the float valve 2013B closes the opening 2013A again. Finally, main embodiments of the present disclosure are shown below.
