<p><P>PROBLEM TO BE SOLVED: To make a location of a selected one of drainage outlets correspond to a location of a drain pipe which is connected to the drainage outlet, to dispense with the setting of a bathroom unit to an extremely high location, to facilitate construction work, and to enable the easy connection to an existing drain pipe even if a location of a trap differs due to a difference of the type and the size of a new bathroom unit. <P>SOLUTION: The catch basin 7 has a drainage inlet 2 formed at an upper surface 1a, and the drainage outlets 3 formed at the lower surface 1b to which the drain pipe 5 is connected, and has a hollow and flat body. The drainage outlets 3 are formed at the lower surface 1b at a plurality of locations, and blocked by blocking means 4. Then the arbitrary blocking means 4 of one of the drainage outlets 3 is selectively opened, allows the drain pipe 5 to communicate therewith, and is connected thereto. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
