An adjustable spa headrest has two side surfaces laterally disposed between front and back surfaces. A first projection extends outwardly from one of the side surfaces. A guide rail, positioned for receiving the projection, allows the spa headrest to be positioned in a number of positions. The guide rail includes a horizontal slot, a vertical slot including a number of spaced notches, each notch defined by a pair of second projections, and a spring arm depending in the vertical slot. When the first projection moves to a position between one of the second projections and the spring arm, the spring arm moves away from the second projection whereupon the spring arm applies a spring force to the first projection in a direction of second projection. In response to positioning the first projection in one of the notches, the spring arm secures the first projection in the one of the notches.

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 method and a system are described for operating a bathing unit system to provide swim-in-place functionality to a swimmer. A communication link is established between the bathing unit system and an auxiliary device worn by or implanted in the body of the swimmer. A signal conveying information associated with the swimmer and originating from the auxiliary device is received. Control signals for controlling operational settings associated with a propulsion assembly of the bathing unit system are derived at least in part by processing the information conveyed by the signal originating from the auxiliary device. The control signals are then released to control the operational settings associated with the propulsion assembly. In another aspect, a graphic display is provided presenting the user with a customized set of selectable swim-in-place configurations derived at least in part by processing a signal originating from an auxiliary device worn by or implanted in the body of the swimmer.

A whirlpool bath with descaling function is provided. The whirlpool bath 1 comprises a bathtub body 10 including a bathtub 11, suction port 20 sucking the water contained in the bathtub 11, first jet nozzles 30 jetting bubble water into the bathtub 11, a circulation pipe 40 including a water supply pipe 41 and a return pipe 42, a pump 50 installed in the circulation pipe 40, a bypass pipe 60 branched from the water supply pipe 41 and connected to the return pipe 42 to directly return the water in the water supply pipe 41 to the pump, and a second jet nozzle 70 mixing air with water passing through the bypass pipe 60 to generate and jet bubble water. The scale of the circulation pipe 40, the pump 50 and the bypass pipe 60 is removed by bubble water generated by the second jet nozzle 70.
