The conventional bathtub waterproof pan described above has a problem that its strength is remarkably reduced because the corners are largely cut off from the bottom surface to the side surfaces.

Further, since the bottom surface is open, a rib for preventing water leakage must be provided around the bottom surface. However, this rib may be too high due to the structure in which the bathtub is placed on the upper side. Therefore, when a large amount of hot and cold water flows, there is a risk that water will overflow from here. Also, in order to prevent this, the waterproof lid must be attached with high sealing properties, so that the cost for the sealing structure is increased and the workability of attaching and detaching the waterproof lid is deteriorated.
