What Temperature Should a Hot Tub Be Set At

Soaking in a hot tub after a long day can take away all your stress and tension. One of the most common questions that new hot tub owners ask is what temperature should a hot tub be set at? This is an important question as high temperature will leave you scalded and uncomfortable while low temperature will not provide the needed relaxation.

There are instances where a person with a medical condition wants to relax in the hot tub, and you need to adjust the hot tub’s temperature accordingly. The hot tub’s temperature also needs to be kept in check if a pregnant woman wants to soak in the hot tub. In all, there are several factors you need to keep in mind when setting the temperature of your hot tub. From personal preference to economical reasons, all factors are crucial while selecting the temperature of your hot tub.

In this article, we are going to take a look at some temperature choices for a hot tub and the one that should be ideal for your usage.

1) Depending on the Weather

If you are thinking of using your hot tub in the summer season, then it makes sense to keep the hot tub at a lower temperature as soaking in water that is too hot can be uncomfortable. You can keep the hot tub at a temperature that is close to your body’s temperature to feel comfortable and relaxed. For those using the hot tub only in the winter season, choose the temperature that you feel most comfortable at. Most people keep the hot tub temperature around 40 degrees C as it is the temperature recommended by the CDC (Center for Disease Control and Prevention)(1).

2) For Unique Cases

If there are elders or pregnant women that want to soak in the hot tub, you need to adjust the temperature according to their comfort levels. Even before getting in the hot tub, elders, pregnant women, or people with medical conditions should consult their physician if a soak in the hot water would be right for them. A temperature closer to body temperature that is 36-37 degrees C should be ideal for most people.

3) Maintain a Constant Temperature

Keeping a constant temperature in the hot tub is essential if you want your hot tub to work at an optimum level. If you keep changing the temperature too often, it will put additional stress on the hot tub’s heating mechanism and that will reduce the life of the heating coils. Also, changing the temperature prevents the hot tub from heating the water at a constant rate, and it can lead to an increase in your electricity bills. In essence, it takes less power to maintain the temperature of the hot tub than to heat up the water every time.

4) For Children

Where there are children in the house, they often want to join their parents in the hot tub. Children, less than five years of age should not be allowed in a hot tub. For children above the age of five years, the temperature in the hot tub should not be more than 35 degrees C, and even then children should not stay in the hot tub for more than five or ten minutes. Also, if the children report unease, cramps, rash, or dizziness, take them out of the hot tub and let them cool down.


To sum up, keeping your hot tub at a recommended temperature is always a good idea, but you should also keep in mind the needs and preferences of those who want to soak in the hot tub. Practice due caution when older people, pregnant women, or children want to soak in the hot tub. It is always a good idea to experiment a little to find the temperature that you find the ideal for your liking. With an optimum hot tub temperature, you will be able to enjoy your hot tub to the maximum.
