A spa facility includes a pliable container, and flexible hoses for connecting to the pump and heater of a conventional pool, as well as to a source of compressed air. A flotation member is secured to the rim of the container. A plastic dome includes double tubes along its rim, one filled with air and the other with water, and is inflated by the pressurized air bubbling up out of the spa container. The pliable container is supported by pool water and/or a supplemental stiff supporting container.
