Further, the other end of the discharge pipe 114 is connected to a sewer pipe or a septic tank (not shown).

Next, the operator places the upper toilet half body 203 separated by the previous work in the same procedure as described above on the lower toilet half body 210. As a result, the upper toilet half body 203 can be placed more stably on the lower toilet half body 210. Next, the operator prepares the indoor water storage tank 107, the first tank water supply pipe 108a, and the second tank water supply pipe 108b, respectively. Then, the operator attaches the indoor water storage tank 107 to the back panel 106 via the hook 107a and the tank support 106a, respectively. Next, the operator uses the second tank water supply pipe 108b to connect the indoor water storage tank 107 and the water discharge nozzle 206 of the Western-style toilet bowl 200. Further, the worker connects the indoor water storage tank 107 to the water supply (not shown) by using the first tank water supply pipe 108a.

As a result, the Western-style toilet bowl 200 is connected to the water supply via the indoor water storage tank 107 and to the sewer via the discharge pipe 114. That is, the operator can switch the flushing method of the unit toilet 100 from the pump-type simple flushing to the complete flushing. The operator can switch the flushing method of the unit toilet 100 from complete flushing to simple pump-type flushing in the same procedure.

In addition, when the worker removes the lower toilet half body 210 from the floor surface 104a of the unit base 101 during maintenance of the Western-style toilet bowl 200, the operator attaches a bolt (not shown) for fixing the outer forming portion 217 to the floor surface 104a. By removing it, the entire lower toilet half body 210 including the discharge tool support portion 215 can be removed from the floor surface 104a.
