Abstract: A spa system of the invention includes a room of a structure having a plurality of faces defining a room interior space. A plurality of panels each have a front surface and a rear, with the front surface of each of the panels having an emissivity characteristic with respect to infrared s radiation of from 0 to approximately 0.3. A securing device is provided for securing each of the panels to one of the faces of the room, with the securing device being positioned on the rear of each of the panels. An infrared radiation emitter generates infrared radiation and disperses the radiation about the room interior space. The infrared radiation emitter is positioned in the interior space such that infrared radiation generated by the infrared radiation emitter strikes the front surfaces of the plurality of panels.
