How to Use a Hot Tub As a Pool

A hot tub functions as a pool when the heat is off.

During the summer months, when the hot water of a spa is not as desirable, you can use the tub as a pool instead. Since both pools and hot tubs use similar sanitizing chemicals, keeping the water cool is all that is required for the hot tub to function as a pool. There are a few obstacles to overcome, because a hot tub's inclination is to heat the water, but a few tricks ensure the water stays cool enough to enjoy during warmer weather.

Instructions

1. Turn the hot tub thermostat's temperature to below 85 degrees Fahrenheit, or turn the heater off.

2. Remove the cover and turn on the air jets to circulate the water, which helps reduce the water temperature.

3. Keep the cover on the hot tub when it's not in use. Keeping the hot tub covered insulates it and prevents sunlight from warming the water.

4. Run the spa at night with the heater and cover off as often as possible to cool the water.

Tips & Warnings

• Apply sanitizers such as chlorine to the hot tub as you normally do to prevent bacterial growth.
