PROBLEM TO BE SOLVED: To enable the automatic washing of a floor pan with a simple structure by placing a bathtub on the floor pan, providing the bathtub with a drain part downward from its bottom, communicating the drain part of the bathtub with a drain port formed at the floor pan and disposing a water sprinkling part communicating the drain part of the bathtub between the floor pan and the bottom of the bathtub. SOLUTION: The hot water accumulating in the bathtub 2 is drained by a drain pipe 10 through the drain hole 9 of the floor pan 1 from the drain part 5 by removing a drain plug 8 from the drain hole 9 of the drain part 4 of the bathtub 2 and in this case, part of the hot water drained from the bathtub 2 flows to the water sprinkling part 5 arranged between the floor pan 1 and the bottom 3 of the bathtub 2 and the floor pan 1 under the bathtub 2 is eventually automatically washed by the hot water sprinkled from the water sprinkling part 5. Consequently, such thing that the dirt accumulates on the floor pan 1 under the bathtub and the consequent generation of malodors or mold to make the bathtub insanitary may be prevented.
