The invention relates to a split type waterproof bottom case, which belongs to the technical field of architectural
ornaments, and comprises a dry area plate, a wet area plate and a weather bar, wherein the dry area plate is formed by a dry area surrounding edge
wall plate, a dry area surrounding edge bottom plate, a dry area base plate, a dry area side plate and a sewer hole; the dry area side plate, the dry area surrounding edge
wall plate and the dry area surrounding edge bottom plate are arranged at the side of the dry area base plate; the wet area plate comprises a wet area surrounding edge
wall plate, a wet area surrounding edge bottom plate, a wet area base plate, a wet area side plate and a floor drain hole; the wet area side plate, the wet area surrounding edge wall plate and the wet area surrounding edge bottom plate are arranged at the side of the wet area base plate; the dry area side plate and the wet area side plate are oppositely arranged; the weather bar is connected to the outer sides of the dry area side plate and the wet area side plate in a buckling way, and is used for connecting the dry area side plate and the wet area side plate. The split type waterproof bottom case provided by the invention overcomes the defects that the traditional bathroom is complex in a waterproof process, high in construction operation requirement, long in construction period and the like; due to the industrialized production, the construction period is shortened, the quick installation is realized, the labor cost is saved, and the
sustainable development is facilitated.
