<P>PROBLEM TO BE SOLVED: To provide a waterproof pan for a bathtub, which facilitates the checking of water leakage from a drainage member arranged on the downside of at least either of a wash place floor and the waterproof pan for the bathtub, without providing the waterproof pan for the bathtub with an inspection hole. <P>SOLUTION: This waterproof pan for the bathtub is installed separately with the wash place floor, and installed below the bathtub which is provided adjacently to the wash place floor. The waterproof pan for the bathtub includes a bottom portion, and a sidewall portion which is elongated upward from the entire perimeter of the peripheral edge of the bottom portion. At least a part of the sidewall portion, on the side of the wash place floor, of the sidewall portions has flexibility. The sidewall portion with the flexibility is horizontally pushed and deformed. This enables the formation of a space for checking the water leakage from the drainage member which is arranged on the downside of at least either of the wash place floor and the waterproof pan for the bathtub. <P>COPYRIGHT: (C)2011,JPO&INPIT |
