PROBLEM TO BE SOLVED: To make the height of bottom surface adjustable freely by connecting coupling portions together with a connecting member of a desired height provided between the adjacent peripheral side walls of a bathtub holding portion and a washing area portion as separate bodies. SOLUTION: A bathtub holding portion 2 and a washing area portion 3 are formed as separate bodies, coupling portions 22, 32 are provided at an adjacent place between respective peripheral side walls, and a waterproof pan main body 1 is constituted by interposing a connecting member 10 between coupling portions 22, 23. A plurality of kinds of connecting members with different heights are provided, the connecting member 10 is selected depending on the installing conditions related to the height of floor surface for installation during work on the site, and the bathtub holding portion 2 and washing area portion 3 are coupled at the coupling portions 22, 23 with a connecting member 10 to one united body. By doing this, the heights of the bathtub holding portion and washing area portion can be freely adjusted and this method can be applied to all bathrooms regardless of the construction of installation floor surface and the type of bathtub main body used, and it is not required to produce many different shapes of waterproof pans so that mass production is possible and stock control can be performed easier. |
