The sides 6 near the sides of the stool 3 where the back side of the thighs come into contact when the bather sits down are sloped downward from the tub side wall 4 toward the tub inner tub 10, and have a step difference with the sides 6. Both side bent portions 8 with the upright surface 7 are formed with a large radius such as R25.

On the other hand, the surface 11 near the center of the seating portion 3 is inclined downward from the bathtub inner tub 10 toward the bathtub side wall 4, and the central bent portion between the central vicinity surface 11 and the stepped surface 7 is formed. 9 is formed of a small R such as R10. Here, the central vicinity surface 11 and both side vicinity surfaces 6 are A-
A 'is connected by a smooth curve that becomes a cross-sectional visual wave shape,
The height of the central vicinity surface 11 is higher than the heights of the adjacent surfaces 6 on both sides, and the hot water flows from the surface 11 near the center to the adjacent surfaces 6 on both sides, and flows to the bathtub bottom surface 2.

According to the present invention having such a structure, even when the bather sits on the stool 3, the surfaces 6 near both sides have a downward slope toward the bathtub inner tub 10, so that the back side of the thigh hits. There is no pleasure. In addition, even when the leg is stretched during bathing and the foot is placed on the stool 3, the back side of the lower leg does not partially hit, so that no discomfort is felt. Further, since both side bent portions 8 are formed with a large radius, discomfort in these bathing postures is further eliminated, and a more relaxed bathing can be enjoyed.

Further, since the height of the central vicinity surface 11 is higher than the both side vicinity surfaces 6, when the butt rests on the stool 3, the buttocks fit the shape of the stool 3 so that the bones partially hit. No discomfort. Further, since the central bent portion 9 between the central vicinity surface 11 and the stepped surface 7 is formed with a small radius, the depth of the central vicinity surface 11 is increased, and a sense of stability can be obtained when sitting on the seat 3. Moreover, since the central vicinity surface 11 has a downward slope from the bathtub inner tub 10 side toward the bathtub side wall 4 side, there is no fear of the buttocks sliding down to the bathtub inner tub 10 side.

As described above, the bent portions 8 on both sides are formed with a large R
On the other hand, by forming the central bent portion 9 with a small radius, the seat can be stably and easily seated. Here, the large R of the both side bent portions 8 is not limited to R25 but may be about R20 to R30, and the small R of the center bent portion 9 is not limited to R15 and is about R5. R
What is necessary is just about 20 or less.

Further, even if the central vicinity surface 11 is not inclined downward from the bathtub inner tub 10 side toward the bathtub side wall 4 but is horizontal, the central vicinity surface 11 is higher than both side adjacent surfaces 6 because the water is hot and cold. Is the surface 11 near the center from the surface 11 near the center
