PROBLEM TO BE SOLVED: To provide a bathtub which enables cleaning of the surface of hot water even when water level varies. SOLUTION: The discharging of hot water 6 on the side of the surface of hot water is made possible by interlocking changes in the level of the hot water within a bathtub 1 to realize electrically cleaning of the surface of the hot water. In this structure, there are arranged a hot water reservoir part (dust recovery chamber 5) formed in an internal wall part of the bathtub, a partition (cover 4) which divides the hot water 6 within the hot water reservoir part 5 and the hot water 6 within the bathtub 1, through hole parts (first opening part 7A and second opening part 7B) which are formed in the partition 4 for communication between the hot water 6 formed by the partition 4 and the hot water 6 within the bathtub 1 and opening/closing plates (first and second floats 10A and 10B) which are slidably supported on the partition 4 to be vertically moved according to changes in the water level within the bathtub 1 to alter the opening degrees of the through holes 7A and 7B.
