What is the best temperature for a hot tub?

Hot tub temperature is really a matter of personal preference and comfort. However, a few things are important to know.

First, for safety purposes we recommend that your spa temperature never exceeds 39 degrees Celsius / 102 degrees Fahrenheit.

Second, a pregnant woman shouldn’t use a hot tub before consulting a doctor.

And third, be certain that your hot tub’s control panel shows actual hot tub temperature as well as set temperature, so you will always be certain of the water’s temperature prior to entering the spa. In warm weather, turning the hot tub temperature control down to keep the water cool is one way to enjoy a refreshing soak.
