CONSTITUTION: A bathroom floor panel is provided with an exterior frame member 41, upper surface waterproof pan 42, and a bathtub installation part, and a reinforcing core material 44 is fixed to positions where reinforcement is required. In this case, a bathroom floor surface is formed of the upper surface waterproof pan 42, and a height of the floor surface is made the same as an upper surface height of a face material of a floor member forming the floor surface of a room to be a bathroom entrance. A peripheral ditch 45 for recovering and draining water flowing on the bathroom floor surface is formed in the peripheral part other than a bathtub installation part, in the inner periphery of the upper surface waterproof pan 42, and a cover body 49 is fitted thereto to form the same height as the bathroom floor surface.
