China Royal Spa suggests to set the water temperature not more than 104 degrees. However, you can select the temperature lower than this according to your needs and health conditions. Studies show that many users enjoy massage and hydrotherapy when the temperature is between 100 to 102 degree Fahrenheit.

If you are going to immerse in the hot tub water individually, it would be best to set the temperature according to your personal preferences. However, if you have a medium to large sized hot tub and you are going to share it with your friends and family, China Royal Spa suggests considering everyone’s health conditions and preferences before setting the water temperature. The ideal temperature for you could be hot for other people, therefore always set the temperature that is ideal for everyone to enjoy the immersing and soaking experience.
Ideal Temperature When Not in Use
No one uses the hot tub 24/7. However, you have to keep it running even if you are not using the hot tub. Therefore, apart from knowing the ideal temperature for use, it is equally important to know the ideal temperature of the hot tub when not in use.
You can select multiple options to maintain the water temperature when you are not using it. If you use the hot tub daily, China Royal Spa suggests not to increase or decrease the water temperature on the daily basis. However, if you intend to use the hot tub after a week, you can keep the hot tub running in two ways. First, many hot tub models come with an economy mode, turn it on, and keep the hot tub running by maintaining the water temperature. However, if your hot tub does not come with the economy mode, you can opt for the second option by manually decreasing the temperature. For summers and spring, 50 degrees is a perfect temperature to keep it running for a week, even if you are not using it.
However, the situation will be different during winters. In winters, if you lower the temperature the water in the hot tub will get frozen and it will damage your hot tub. Therefore, China Royal Spa suggests properly draining, cleaning, and winterizing the hot tub if you are planning not to use it for quite a while.
Ideal Temperature According to Weather Conditions
Weather conditions have a direct effect on your body. Therefore, while immersing in the hot tub it would be better to set the ideal temperature of the hot tub according to the weather conditions.
Everyone wants to immerse and soak in the hot water during winters because of the cold weather. Therefore, you can set the water temperature higher than usual. You can set the water temperature between 102 degrees to 104 degrees during winters. However, despite the cold weather, you should consider users’ preferences because some users cannot endure high temperatures even during winters.
However, in summers, no one wants to immerse and sit in the warm water; therefore, you should keep the water temperature lower than usual in summers. You can set the water temperature between 80 to 85 degrees during summers. However, again, don’t forget to consider the choice, preferences and health conditions of the users before setting the water temperature.
Ideal Water Temperature According to Health Conditions
Hot tubs are designed and manufactured to give the users multiple health benefits and advantages. However, there are certain health conditions that could be adversely affected if the hot tub has high water temperature. Therefore, it would be better to keep those health conditions in mind and set the temperature accordingly.
Heart Disease
If you have any sort of heart disease, circulatory disease or blood pressure issues, China Royal Spa suggest you not to sit and immerse in the hot water. If you have any such disease, consult your doctor and act upon his advice because he could give you authentic and accurate advice. If your doctor allows you to sit and immerse in the hot tub, China Royal Spa suggests to keep the water temperature at a lower level. It would be best if you keep the temperature between 90 to 95 degrees.
Pregnancy
If you are a mommy to be, you need to be extra careful about the hot tub water temperature. Body temperature during pregnancy remains high, and if you immerse and soak in the hot water, it could be dangerous for the baby and your health. Anything above 102 could cause birth complications during delivery. If you are pregnant, China Royal Spa suggests avoiding using the hot tub. However, once you deliver your baby, set your ideal temperature and immerse in the warm and soothing water to nourish your stiff and tense body muscles.
Ideal Temperature According to Age Groups
Apart from the other factors, age is also an important factor that you should consider while setting the water temperature of the hot tub. Young adults could bear the high temperature, but older adults and children could not bear the high water temperature.
If you are going to share the hot tub with old people and children, China Royal Spa suggests not to set the water temperature higher than 98 degrees.
