A tray-like water receiving pan 1 is disposed in such a manner as to pass directly below a piping implement provided in a penetrating state in a side wall 31 of the bathtub, and a connecting portion of a hot and cold water supply pipe 6 disposed between the side wall 31 of the bathtub and the bath apron 5.

Description

  In the present invention, a bathtub and a washing pan are juxtaposed on the installation surface, and a gap between the flange projecting on the washing pan side of the bathtub and the embankment provided on the bathtub side of the washing pan is closed with a bath apron. It relates to the bathroom unit structure.

  Conventionally, there are bathroom units that are assembled as finished products after parts such as bathtubs, washing pans, wall panels, and ceiling panels are molded in a factory and the parts are brought into the field. Bathroom units are roughly classified into a full panel type in which a bathtub is placed on a floor pan supported on the installation surface, and a half panel type in which a bathtub and a floor pan are installed side by side on the installation surface. The half-panel type bathroom unit is widely used in hotels, condominiums, general houses, and the like because the number of parts can be reduced as compared with the full-panel type.

  Along with the multi-functionality of reheating and jet jets, piping equipment such as reheating adapters and jet jet devices are attached to the bathtub of the bathroom unit. In addition, piping such as a hot water supply / water supply pipe is disposed in the vicinity of the bathtub. There is a possibility that hot water leaks out from the pipe fitting or the connection portion of the pipe. For example, the leaked hot water may flow down to the installation surface and leak downstairs.

  In such a situation, the full-panel type bathroom unit can receive hot water with a waterproof pan on which the bathtub is placed, and can prevent water from falling onto the installation surface. On the other hand, since the waterproof panel is not arrange | positioned under the bathtub, the half panel type bathroom unit cannot catch hot water, and cannot prevent the water falling to an installation surface.

  Therefore, conventionally, a half panel type bathroom unit structure in which a water receiving member for receiving leaked hot water is attached to a leaking dangerous place has been proposed (for example, Patent Documents 1 to 3).
