DRAINAGE STRUCTURE OF BATHROOM UNIT

PROBLEM TO BE SOLVED: To prevent drainage from a bathtub from flowing back to a bathtub pan to rapidly dispose of the drainage from the bathtub while preventing a perforated plate of a bathtub pan trap from being plugged with dust such as hair included in the drainage. SOLUTION: The bathtub pan trap 3 receiving drainage flowing out of the bathtub 1 and drainage from the bathtub pan 2 is mounted to the back side of the bathtub pan 2 on which the bathtub 1 is placed. The bathtub pan trap 3 and a washing place pan trap 5 receiving the drainage from the washing place pan 4 are connected by a drain pipe 6 to allow the drainage from the bathtub 1 and bathtub pan 2 to flow to the washing place pan trap 5. The drain pipe 6 is formed of a bathtub drain pipe 61 allowing the drainage from the bathtub 1 to flow through, and a bathtub pan drain pipe 62 allowing the drainage from the bathtub pan 2 to flow through. A passage 7 for leading the drainage from the bathtub 1 to the bathtub drain pipe 61 is formed in the bathtub pan trap 3, and one end 62a of the bathtub pan drain pipe 62 is opened into the bathtub pan trap 3.
