PROBLEM TO BE SOLVED: To provide a highly efficient complicated nozzle shape and to discharge water efficiently by arranging a water passage forming member for forming a nozzle water passage toward a waterwheel and/or a drain passage from the waterwheel inside a housing on the outside of the waterwheel. SOLUTION: In a bathroom washing apparatus 1, a housing 3 is formed at the tip of a grip part 2 forming a water passage 2a, and inside the housing 3 with an opened bottom side, a fitting chamber S2 communicated with the water passage 2a is formed, while a fitting projection part 3a is protruded inward inside the fitting chamber S2. A waterwheel chamber S1 housing a waterwheel is formed while communicated with the fitting chamber S2. Inside the waterwheel chamber S1, a waterwheel 4 is arranged rotatably, while a water passage forming member 5 is fitted or stuck to the fitting chamber S2 on the outside of the waterwheel 4. A nozzle water passage and a drain passage 52 are formed in the water passage forming member 5.
