ABSTRACT:
A shower-sauna apparatus includes an electrically insulative container for accomodating a volume of water to be heated. A vertical central tube extends through the container and has a threaded upper end adapted to be connected to a source of water and a threaded lower end through which steam or hot water is discharged into a sauna-shower area defined by a flexible curtain suspended from a flat dish-shaped member secured to the threaded lower end of the central tube and defining the top wall of the sauna-shower area. A plurality of spaced, tubular electrode plates are disposed in the container and are adapted to be connected to an electric power source for passage of electric current through the water between the plates to generate Joule heat for automatically and instantaneously heating the volume of water to enable generation of either steam or hot water. The central tube is divided by a stopper into an upper water inlet portion and a lower steam or hot water outlet portion. A water control valve is provided to regulate the rate of water flow into the container and thus control the generation of steam or the temperature to which the water is heated. A shower head can be either attached directly to the lower end of the control tube or connected thereto by a flexible hose. A check valve prevents generated steam from exiting through the upper end of the central tube. Alternatively, a dish filled with aromatic or medicinal herbs can be connected to the hose when steam is to be delivered to the sauna-shower area.
