PROBLEM TO BE SOLVED: To quickly change the sink into a convenient two-tank type sink by covering the two-tank type sink providing a drain plug in each tank on an existing sink. SOLUTION: A sink is divided into a tank for washing dishes and another tank for rinsing them at a prescribed rate to provide a drain port in each tank. Next, a drain plug 1 can cope with hot water and muddy water, and drains the water by pulling a chain 2. In addition, a window 3 for preventing water from leaking on the partition part of the rinsing tank is provided so as not to overflow water. Full water flows down in a space 4 between the partitions from the window. Furthermore, water drained from the three drain ports is collectively guided to the drain port of the existing sink, a drain ditch 5 and a drain pipe 6 are attached and the bottom of the sink is protected from mold and fouling. Furthermore, a foot 7 for passing the pipe 6 is attached. Thereby washing down can be performed, at the same time, rinsing can be performed, and, since the water tank is small, water resource can be saved.
