An upper step surface 24 lower than the frame surface 23 and an upper step surface 2 are provided inside the bathtub 2.
A lower step surface 25 lower than the upper step surface 25 is provided along the bathtub side wall 22 on the washing station 4 side, and an upper armrest surface 26 having substantially the same height as the upper step surface 24 and a height substantially equal to the lower step surface 25. Lower armrest surface 27
However, it is provided on the bathtub side wall 22 opposite to the washing place 4. The upper step surface 24 is provided at a position near the frame-side seating portion 231, and the lower step surface 2
Reference numeral 5 is provided at a position continuous with the upper step surface 24. The upper armrest surface 26 is provided at a position facing the upper step surface 24, and the lower armrest surface 27 is provided at a position facing the lower step surface 25. Further, the upper step surface 24
The upper armrest surface 26 is provided with the bathtub bottom surface 21.
380 mm above the lower step surface 25 and the lower armrest surface 27.
Is arranged at a height of approximately 230 mm from the bathtub bottom surface 21.

A shower faucet 5, an opening / closing operation lever 6 for a drain port 28, and an L-shaped horizontal handrail 7 are provided on a frame surface 23 of the bathtub 2, and a jet nozzle ( (Not shown), and a bubble nozzle (not shown) is provided on the bottom surface 21 of the bathtub. A jet device (pump or the like) for generating a jet from the jet nozzle, a bubble device (pump or the like) for generating bubbles from the bubble nozzle, and piping are not shown,

Since the jet device, the bubble device, and the piping are provided in the space behind the upper step surface and the lower step surface, a large bathroom space can be secured.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. Even if present, it is included in the present invention. For example,
The arrangement of the upper step surface 24 and the lower step surface 25 is not limited to that shown in the embodiment, and the positions of the upper step surface 24 and the lower step surface 25 are reversed as in the bathtub 2a shown in FIG. Alternatively, as in a bathtub 2b shown in FIG. 7, the upper step surface 24 and the lower step surface 25 may be arranged along the bathtub side wall 22 on the entrance 1 side.
Furthermore, it is preferable to provide a step on the outer surface of the bathtub on the side of the washing area, since the in / out operation of the bathtub is further facilitated outside the bathtub.

[0022]

As described above, in the bathtub and the bathroom unit of the present invention, the bather sits down while gradually lowering the waist height from the frame surface to the upper step surface, the lower step surface, and the bathtub bottom surface. Therefore, there is an effect that even elderly people, infants and physically handicapped persons can easily move and bathe in the bathtub easily.

Further, in the bathtub according to the second aspect, an upper armrest surface having substantially the same height as the upper step surface is provided at a position facing the upper step surface. Since a lower armrest surface having substantially the same height as the lower step surface is provided at a position facing the lower step surface, it is possible to relax and take a bath by stabilizing the body with both arms, and to use both arms. You can stand up easily by supporting your body.

Furthermore, in the bathtub according to the fourth aspect, since at least a part of the hot water supply device is disposed in the space behind the upper step surface or the lower step surface, a large bathroom space can be secured.
