Abstract: An enclosure including a quasi-bathtub embedded in a structure and underneath a treatment hood has a shallow, substantially rectangular, practically flat bottom and a longitudinal basin extending from the head side. The basin is and has less depth than the tub. Air evacuation ports are on a ledge of the tub and air intake ports slightly project above the upper ledge of the tub. A semi-cylindrical, removable hood fits on the upper ledge of the tub. A blower is connected between the evacuation ports and air intake ports. Pivoting manifolds are connected to laterally orientable shower heads. Red and blue lights are alternately on for stimulation and relaxation, respectively.
