Note: The tools you'll need vary by the brand and size of the whirlpool unit. Just make sure you have everything you need before you start.
- First, make sure that you have enough power available to run the unit. You need a GFCI or Ground Fault outlet. A GFCI will immediately turn off the power if there is an electrical problem.
- A whirlpool takes a lot of water and to get the best benefit, you'll want the water to be around 90 to 95 degrees. Also, it takes a lot of water to fill a whirlpool tub, so you may need to install a larger water heater or a point-of-use water heater to meet the demand. Many manufacturers sell an inline heater that will heat the water as it goes through the pump.
- If installing a whirlpool into an older home, make sure the floor can support the extra weight of a full tub. A small filled whirlpool weighs about 475 pounds. Check the manufacturers requirements to make sure your floor is suitable to support the load.
- Inspect the tub for shipping damage such as dents and cracks before bringing it inside.
