PROBLEM TO BE SOLVED: To provide a drainage structure for a bathroom capable of quickly increasing the head of a drain at a wash place and increasing the distance between a bathtub pan and the position of a foundation such as a floor slab in a syphon drainage system. SOLUTION: A hose 36 extends from a bathtub drain port 30B downward through the bathtub pan 38, and is disposed toward a catch-basin part 35 along the rear side (lower side) of the bathtub pan 38. The hose 36 extends through the side wall of the catch-basin part 35, its one end 36A projects from the rear side to the front side of the catch-basin 35, and is connected to a drain trap 40.
