PROBLEM TO BE SOLVED: To simplify the process of changing the back wall inclination and to facilitate the descaling work as well by detachably attaching an L-shaped backrest to span an arrest recess and armrests and the back wall with one part of the backrest roughly horizontal and the other part inclined sharper than the back wall. SOLUTION: For a bather 9 who favors a bathtub 1 with a back wall 23 inclined gentle, a backrest 5 is removed, a pillow mat 59 is placed into and arrest recess 4, the bathtub 1 is filled with water, and the bather 9 is relaxed with the head on the pillow mat 59 and the elbows on armrests 25. The backrest 5 is folded and stowed away. For the bather 9 who favors the bathtub 1 with the back wall 23 inclined sharply, it is so set that te backrest 5 spans the arrest recess 4, the back wall 23, and the armrests 25. The bather 9 enters the bathtub 1, a places the elbows on the armrests 25, and leans against the backrest 5. In this case, a part 52 of the backrest 5 is inclined nearly 90 degrees, and the bather leans against this part 52 of the backrest 5. |
