Power Supply for a Air Jet Massage Bathtub
Electrical Circuit requirements and the GFCI Protection for Hydro Massage and Air Jet Bathtubs
Providing Safe Power for an Air Jet Bathtub
Question: I am in the process of installing a new slipper tub in my bath.
The blower with the unit is an air blower (not a pump) and it is rated at 400 watts.
Am I correct in assuming that I do not need a dedicated circuit since this is 4 amps and can be wired into a simple lighting circuit?
This electrical question came from: Steve, a Homeowner from Springfield, Virginia.
Thanks for your electrical question Steve.
GFCI Protection for Hydro Massage and Air Jet Bathtubs
- Due to the low amount of power that is required for the air jet slipper bathtub you are not required to install a dedicated circuit.
- The outlet or circuit that will be providing the power must be protected by a GFCI device.
- Some air jet bathtubs have a built in heater so a dedicated circuit may be required depending on the required amperage for the heater unit.
- Always consult the manufacturers installation manual for the model you have purchased for detailed circuit requirements.

Electrical Tips to Help You Wire it Right
The Safest Way to Test Electrical Devices and Identify Electric Wires!
The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!
The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included
Tests standard 3-wire outlets
Light indicates if wiring is incorrect
