Abstract: Hot air blowing means is connected by a hose to a porous gridiron immersed in the bath. The hot air blowing means are contained in a first housing, adapted to be located adjacent the bath to be manipulable by the bather and including means for regulating the speed and duration of the operation of the hot air blowing means. A power pack for driving the hot air blowing means comprising at least a transformer is contained in a second housing independent of the first housing and separably locatable remote from the bather. The transformer has an input connected to a source of line current and a low voltage output no greater than 24 volts. The heating and blowing means are operable by the low voltage and are connected by an elongated low voltage cable to the transformer.
