PURPOSE: To keep clean feeling after a shower by pivotally supporting a tread stepped down by a leg to a part of the floor face of a shower room in the shower room, in which a door is installed on one side of a space closed from the periphery and a shower mechanism is mounted on the inside of the space.

CONSTITUTION: The plane of a tread 17 is erected approximately vertically by the elastic force of a spring 29 in the midst at a time when warm water is poured over a user from a shower top 20. When the body is washed away and the moisture of the body is wiped off, a rotary cylinder 28 is rotated to a fixed shaft 27 when the user steps down the upper end of the tread 17 by its leg, the tread 17 is tuned up to the state close to a horizontality, and a leg 30 is brought into contact with a floor board 15 and held under the state. Since the tread 17 is vertically erected previously, the tread is dry because no warm water from the shower top 20 adheres, and the leg, from which moisture is wiped off, is placed on the dry tread. Clothing is taken out from a housing 21, and the user puts on clothing. Accordingly, a shower room 11 can be utilized hygienically without moistening the sole of the foot and clothing.
