PROBLEM TO BE SOLVED: To provide a wall rear side piping capable of minimizing a space between the rear surface of the wall panel of a bathroom unit and a building frame and assuring a sufficient feed water volume and durability. SOLUTION: This bathroom unit comprises a water feed pipe and a hot water feed pipe led from the underside of the floor pan of the bathroom unit and a connection pipe connected from the water feed pipe and the hot water pipe to a water faucet hardware installed in the bathroom unit. A shower pipe is laid down from the water faucet hardware along the wall rear side of the bathroom unit, and separated from the water faucet hardware to form a shower discharge water channel. The wall rear shower pipe is generally identical in sectional area with that of the water feed pipe and hot water feed pipe, and formed to a flat shape. Thus, since the same amount of sectional area can be achieved with less depth, the passing water amount can be assured sufficiently. |
