Abstract
Abstract A molded unitary substantially watertight structure is provided with an entrance opening and an enlarged drain opening. Rest room fixtures are provided within the structure with means for covering paper dispensers and waste receptacle. A plurality of various types of spray nozzles are provided within the structure to create a fog, a direct spray on the rest room fixtures and overlapping sprays throughout the structure, and floor flushing sprays for flushing debris through the drain opening. A combination heater-blower distributes the fog and dries the structure and fixtures. Various types of liquids are used to clean, sanitize and deodorize the structure. In one embodiment the heater-blower and nozzles are attached to a self-contained independent ceiling structure which may then be secured to a conventional rest room.
