PROBLEM TO BE SOLVED: To lay a floor which constitutes a double floor structure in a bath room with no provision of a grating and to prevent a floor pan which can hardly be cleaned due to the double floor structure from being unsanitary, by gathering hot water flowing from a slid door to a lower frame of an attaching frame, at one position, and by rapidly draining the hot water. SOLUTION: A bath room 1 is composed of a bathtub and a washing place 6. At least the washing place 6 is composed of the floor pan 2, and the bathroom 1 is partitioned by a door 15 from an adjacent room 13, the door 15 being erected by means of an attaching frame 14 laid between the washing place 6 and the adjacent room 13. In thus formed bath room 1, a floor 19 is additionally laid in the washing place 6 so that the floor and a lower frame 16 of the attaching frame 14 are substantially flush with the floor 17 of the adjacent room 13. A drain channel 24 having a downward slope and opened to the washing place 6, for gathering water flowing the latter from the upper surface of the lower frame 16 is provided in the lower frame 16. This drain channel 42 is connected to a drain port 23 formed in the washing place 16 on the bathtub side through a drain pipe 24 laid along the lower surface of the floor 19. |
