PURPOSE: To prevent steam from leaking outside of a room by providing a wind-up type water-impermeable roll blind on the room side of a window opening of a sauna room or the like.
CONSTITUTION: Wall panels 3, a ceiling panel and the like are assembled on a lower body 1 so as to define a space in which a bathtub 2, a shower device 8 and the like are incorporated. A mist generating device 13 is laid on the wall 3 so as to fill steam in the room which may be therefore used as a sauna room. A window 10 such as a bay-window 10 is provided to the wall 3, and a wind-up type roll blind 11 made of water-impermeable materials is laid at the window 10 on the inside of the room. During use of bathing or using as a sauna room, the blind is pulled down in order to prevent steam from leaking outside of the room. With this arrangement, it is possible to enhance the efficiency of the sauna facility.
