  The unit bath having the bathroom floor frame having such a configuration is constructed as described below. First, according to the installation height of the bathroom floor frame, each bolt leg 50 is inserted while being screwed into the female screw portion 35A of each leg receiving portion 30. Then, the bathroom floor frame is temporarily installed on the installation surface 5. In a state where the bathroom floor frame is temporarily installed on the installation surface 5, a bolt such as a wrench for M16 is used so that the height of the washing floor 3 is substantially equal to the height of the floor of the adjacent dressing room. By rotating the leg 50, the installation height is finely adjusted. Then, using a tool such as a spanner for M16, each locking nut 70 is rotated to contact the lower end edge of the leg receiving portion 30 from below the leg receiving portion 30. Thus, the bolt leg 50 screwed into the female screw portion 35A of the leg receiving portion 30 can be prevented from being loosened. Next, the bathtub 1 is mounted on the bathtub mounting portion 10B of the bathroom floor frame and fixed while the drain port of the bathtub 1 is connected to the drain pipe.
