PROBLEM TO BE SOLVED: To sufficiently ensure the drainage capacity of a bathroom from a door frame without enlarging a pipe, by constituting the bathroom such that a groove of the door frame which is built almost flush with a wash-place surface of a waterproof pan can collect water and that the pipe for introducing drainage from the door frame onto a bathtub-side waterproof pan is provided. SOLUTION: The bottom surface of a bathroom is constituted by connecting a bathtub-side waterproof pan 1 and a wash-place-side waterproof pan 4 to each other by means of connecting portions 1c, 4b, then setting a bathtub 2 on a bathtub setting surface 1a of the bathtub-side waterproof pan 1, and arranging a drainage trap 3 in the bottom surface of the bathtub setting surface 1a. A door frame 5 is set almost flush with the wash-place surface 4a, at the external edge of a wash-place surface 4a of the wash-place-side waterproof pan 4. Water and hot water flowing from the wash-place surface is collected by a rail groove 5a of the door frame 5 and then allowed to flow downward. A drainage metal fitting 6 is attached onto the bottom of the waterproof pan 4 below the door frame 5, which fitting 6 collects the water flowing from the door frame 5 and introduces the same through a pipe 7 onto the bathtub-side waterproof pan 1.
