A bathroom unit is known that is installed by assembling a floor pan, a bathtub, and a bath apron at a construction site. In such a bathroom unit, a drain trap is connected between the drain section of the floor pan, the drain section of the bathtub, and the drain pipe in order to drain water from the floor pan or bathtub into the drain pipe.

Patent Document 1 proposes the use of a drain trap including a flexible pipe in order to reliably connect the drain trap even when the vertical position of the bathtub with respect to the floor pan is different. However, since such drainage traps use flexible pipes, water leakage may occur due to poor connections.

Therefore, in Patent Document 2, a pedestal is provided under the floor pan and the bathtub, and a drain trap that does not include a flexible pipe (that is, is integrally formed) is fixed to the pedestal, so that it can be installed on the pedestal. It has been proposed to connect drain traps to the floor pan drain and to the bathtub drain. Moreover, Patent Document 2 proposes that the vertical position of the bathtub with respect to the floor pan is determined by a pedestal provided under the bathtub.

However, since such a pedestal is usually made of a metal member, there is a problem in that providing the pedestal under the bathtub increases the manufacturing cost of the bathroom unit.
