An Overview of Parts and Materials
Jets: Jets move water throughout the tub. Whirlpools may use air jets, water jets, or a combination. Air jets use a larger number of smaller openings, while water jets have a smaller number of larger openings. Air and water jets offer comparable performance, although air jets are preferable if you will be using aromatherapy salts and oils.
Motors: The motor operates the pump and may be single-speed induction, multispeed induction or brush-style. Induction motors are more durable, while multispeed motors offer greater control. Installing the motor away from the tub will help to reduce noise.
Pumps: The pump pushes water through the jets and is installed in a separate part of the bathroom or located behind a panel at one end of the tub. Pumps range from 1/2 hp to 2 hp or higher. Multiple speeds offer a wider range of message options. To facilitate maintenance, the pump should be located in an easily accessible area.
Finish: The tub finish not only provides a stylish appearance but also protects the tub from scratches and dents. Finishes come in different materials, including gel coatings and enamels.
Wiring: The wiring connects the motor and heater to the tub. The motor and heater will require separate 120V circuits with a ground fault interrupter.
Switches: The switch activates the pump. For safety reasons, electric switches must be located away from the tub to prevent shocks. Air switches are nonelectric, however, and may be located on the tub. Timers may be required.
