CONSTITUTION:A floor pan 1 is divided into a bathtub placing part 2 and a washing place 4 by installing a starting partitioning wall 6, and a drain part 5 is formed in the washing place 4. A bathtub 13 is placed in the bathtub placing part 2, and a drain passage 8 communicating from a bathtub drain port 3 to the drain part 5 is arranged outside the bottom of the floor pan 1. Further, an apron 9 is installed between the partitioning wall 6 and the bathtub 13. Therefore, the inflow of the dirty water into the lower part of the bathtub 13 is prevented, and the bathtub placing part 2 can be always kept clean. |
