  As shown in FIG. 2, the main body 2 of the unit bath 1 is formed by a bathtub 4 and a waterproof pan 5 that are arranged side by side. The side-by-side bathtub 4 and the waterproof pan 5 are integrally formed by heating and pressurizing a thermoplastic resin with a mold to form the main body 2. As shown in FIG. 1, after the integrally molded main body 2 is assembled in a bathroom 6 of a building such as a hotel, a wash basin 7 or a toilet 8 is assembled to the main body 2 and predetermined piping is performed. It can function as a bathroom in a hotel or apartment. As shown in FIG. 1, the bathroom 6 is surrounded by a room wall 9, but a part of the room wall 9 is opened as an entrance / exit 3, and a door 10 is provided at the entrance / exit 3 so that it can be opened and closed. It has been. The user enters and exits the bathroom 6 through the entrance 3 with the door 10 opened.

  The bathtub 4 of the main body 2 is a bathtub for bathing, and its periphery is surrounded by a tank wall 11. Reference numeral 12 denotes a tank wall located on the waterproof pan 5 side in the tank wall 11 around 4, and entering and leaving the bathtub 4 is carried out across the tank wall 12 on the waterproof pan side.

  The waterproof pan 5 is continuous at the side-by-side position of the bathtub 4 in a state of being lower than the bathtub 4. A plurality of drain openings 14 are opened on the floor surface 13 of the waterproof pan 5. The drain port 14 includes a drain groove 14 a on the bathtub 4 side and a drain port 14 b on the doorway 3 (door 10) side of the bathroom 6. Each drain port 14 (14a, 14b) is provided with a grating 18 to prevent foreign substances from flowing into the pipe (see FIG. 3). A plurality of drain grooves 15 are formed on the top surface of the floor surface 13 of the waterproof pan 5 along the vertical and horizontal directions. The plurality of drainage grooves 15 also serve as an anti-slip action during use. A low-height enclosure wall 16 is formed around the body 2 including the bathtub 4 and the waterproof pan 5 to prevent leakage of water flowing on the floor 13 from the body 2. ing. In FIG. 2, reference numeral 19 denotes a toilet drain port formed in the waterproof pan 5 for draining the toilet 8.

  In this embodiment, the floor surface 13 of the waterproof pan 5 is inclined so that the floor surface portion 13a on the bathtub 4 side and the floor surface portion 13b on the doorway 3 (door 10) side are lower than the other floor surface portions 13c. Is formed.

That is, as shown in FIG. 3, the floor surface 13 of the waterproof pan 5 is formed between the bathtub 4 and the entrance 3, and the other floor surface portion 13 c in the substantially central portion of the floor surface 13 in the width direction is the highest. The other floor surface portions are inclined so that the height gradually decreases as they move away from 13c. By inclining in this way, water flows well toward the floor surface portion 13a on the bathtub 4 side and the floor surface portion 13b on the doorway 3 side. The drainage port 14a on the bathtub 4 side is formed in the floor surface portion 13a on the bathtub 4 side, and the drainage port 14b on the entrance / exit 3 side is formed in the floor surface portion 13b on the entrance / exit 3 side to discharge the flowing water. .

  In FIG. 3, the code | symbol 31 is a drain pipe. In this embodiment, the drain pipe 31 is piped below the concrete slab floor 32 of the building, and the drain ports 14a and 14b are connected to the drain pipe 31 for drainage. In such a structure in which the drain pipe 31 is piped below the concrete slab floor 32, it is not necessary to dispose the drain pipe on the concrete slab floor 32 as in the prior art, and the floor surface of the concrete slab floor 32 and the unit bath 1 is used. It is not necessary to form a space for disposing the drain pipe between the first and second pipes. For this reason, the floor surface 13 of the waterproof pan 5 in the unit bath 1 can be brought as close as possible to the concrete slab floor 32.

Thereby, the level | step difference of the floor surface part 13b by the side of the entrance / exit 3 in the floor surface 13 of the waterproof pan 5 can be made small, and the height of the entrance / exit 3 of the bathroom 6 can be made small. For example, in the past, the step at the entrance / exit required about 170 mm from the concrete slab floor 32, but in this embodiment, the step can be as low as about 26.5 mm from the concrete slab floor. Then, by finishing the floor outside the bathroom 6 with porcelain tiles or the like (see FIG. 4), the level difference can be reduced and the floor can be made nearly flat. As a result, it is possible to provide a barrier-free function for entering and exiting the bathroom 6, so that even an elderly person or a handicapped person does not trip when entering or exiting the bathroom 6, and can safely enter the bathroom 6. It becomes possible to go in and out.

  In this embodiment, as shown in FIGS. 3 and 4, a damming portion 33 is formed at an end of the floor surface 13 of the waterproof pan 5 on the doorway 3 (door 10) side. The damming portion 33 is formed integrally with the floor surface 13 to constitute a part of the floor surface 13 (that is, the floor surface portion 13b on the doorway 3 side).

  The damming portion 33 is formed so as to be located further on the entrance / exit 3 side than the end of the floor surface portion 13b on the entrance / exit 3 side. The damming portion 33 is formed at a height capable of damming the water of the waterproof pan 5, and therefore has a height (step) substantially equal to the floor surface portion 13 b on the doorway 3 side. By forming such a damming portion 33, it is possible to prevent water from leaking out of the bathroom 6 from the doorway 3 (door 10).

  In this embodiment, a wood base material 34 is provided at the entrance / exit 3 (door 10) corresponding to the damming portion 33. The wood base material 34 is a base material having substantially the same height as the damming portion 33, and the tread plate 35 is stretched over the wood base material 34 and the damming portion 33, so that the upper portions thereof are covered. ing. For the tread plate 35, for example, a corrosion-resistant metal thin plate such as aluminum is used. The tread board 35 is fixed by screwing a screw 38 toward the wood base material 34 in a state of covering the damming portion 33 and the wood base material 34. In addition, as shown in FIG. 4, it is preferable from the point of entering / exiting the bathroom 6 to use as the step board 35 the thing of the shape where the center part raised a little with respect to both ends.

  In addition to the above, an interior finishing material 36 is laid outside the doorway 3 (door 10) in the concrete slab floor 32. The interior finishing material 36 is made of porcelain tile or tile carpet. The interior finishing material 36 is fixed on the concrete slab floor 32 at the outer portion of the entrance 3 through an adhesive 37. When tile carpet is used, the adhesive 37 can be easily detached by using a product pre-applied to the tile carpet. The height (thickness) of the damming portion 33 and the wood base material 34 is reduced by the height (thickness) of the interior finishing material 36. For this reason, it becomes easy to make the level | step difference of the entrance / exit 3 of the bathroom 6 into 12.7 mm (1/2 inch) or less, or to make it flat without a level | step difference. As a result, a better barrier-free function can be provided, and the bathroom 6 can be safely entered and exited. When the interior finishing material 36 is a porcelain tile, it is preferable to interpose a sealing material 39 between the interior finishing material 36 and the step board 35.

  In this embodiment, as shown in FIG.2 and FIG.5, the recessed part 22 for straddle is formed in the tank wall 12 by the side of the waterproof pan 5 in the bathtub 4. As shown in FIG. The straddle concave portion 22 is formed by lowering the upper end portion 21 of the tank wall 12 on the waterproof pan 5 side in a curved shape, and the waterproof pan 5 side without greatly raising a foot when entering or leaving the bathtub 4 The tank wall 12 can be straddled. For this reason, going into and out of the bathtub 4 is easy and safe. Moreover, the entrance / exit with respect to the bathtub 4 can be smoothly performed by forming the straddling recess 22 in a curved shape.
