SOLUTION: An FRP washing place 1 and an adjacent FRP bathtub 2 are inserted into an opening inside a supporting frame 12 extended from the upper end of an apron 11 erected at one end of the washing place 1. The washing place 1 is installed on one half of a plywood bathroom floor 3. The bottom of the bathtub 2 is inserted into an opening 31 formed at the other half of the bathroom floor 3. The lower end of a column 14 supporting the supporting frame 12 is erected on a frame 141, the leg 142 of the frame 141 is installed on the bathroom floor 3. The bathroom floor 3 is supported on a large floor beam 4 at one end, on a small floor beam 41 at the halfway point, and on the large floor beam 4 supported on a concrete foundation 42 at the other end.
