A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.

A passive cooling system for an electric motor drive circuit in a bathing installation, including a section of hollow pipe made of a thermally conductive tubing material, the pipe configured to form part of a water recirculation path of the bathing installation. An adapter structure has a conformal surface configured for attachment to an outer surface of the pipe and a circuit contacting surface for attachment to the motor drive circuit, the adapter structure fabricated of a thermally conductive adapter material. The adapter structure provides a thermal conductive path between the motor drive circuit and the pipe section, configured to pass heat generated by the circuitry to the pipe section and into spa water flowing through the water recirculation path, to cool the circuitry and warm the spa water.

An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

Disclosed is a disposable for use with a surface that defines a basin for receiving liquid. The disposable has a pair of surfaces spaced apart from one another by a tubular sidewall. One of the pair of surfaces is positioned, in use, against the basin-defining surface. In use, gas issues through the sidewall in the form of bubbles. The disposable is useful in association with foot spas and the like. A mechanism for puncturing a liner is also disclosed.

A steam generator for a shower steam system includes a first chamber, a second chamber, and an intermediate heat transfer member. The first chamber is configured to receive water. The second chamber is configured to receive a flow of air. The intermediate heat transfer member fluidly separates the first chamber from the second chamber. The intermediate heat transfer member includes a heating element configured to generate heat energy. The intermediate heat transfer member is configured to transfer heat energy generated by the heating element to the first chamber to generate steam in the first chamber, and transfer heat energy generated by the heating element to the flow of air in the second chamber.

A bath system comprises a tub and a fluid injection system. The tub has a jet orifice, and the fluid injection system is fluidly coupled to the jet orifice. The fluid injection system comprises a conduit, a heat source, an air supply source, and a fluid injector. The conduit has an opening. The heat source is coupled to an outer portion of the conduit external to the opening. The air supply source is fluidly coupled to the conduit, and is configured to provide a flow of air to the central opening. The fluid injector is configured to provide water to the flow of air to produce a combined flow of air and water. The heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the opening before the combined flow enters the tub through the jet orifice.
