This is a common question from those looking into purchasing a hot tub. There are a few things to consider when answering this question, including the temperature range of your hot tub, the weather and your health.

Hot Tub Temperature Range

Most hot tubs, including our all American Artesian Spas, have a maximum temperature setting of 40°C for safety reasons. Anything above that can be dangerous and poses serious health risks. Some customers have commented that 40 degrees is very hot and can be unbearable. If so you can turn the temperature down slightly, though should not need to go any lower than around 26 degrees even on a hot, summers day to cool down. We recommend setting your temperature between 37°C-40°C to ensure you enjoy the maximum benefit that hot water provides. 

Body Temperature Vs. Hot Tub Temperature

Your body temperature is generally between 36°-37°C, so if the water is under 37 degrees then you may experience a slight chill when entering the water. This can be a welcome sensation in hot weather when you want to cool off. Alternatively, in the winter when the outdoor temperature is much cooler, you may want to set your hot tub a few degrees above your body temperature. When the air around you is cold the hot tub will cool slowly with the cover off so if you plan on a longer soak, you will need to allow those couple of extra degrees to stay warm for longer!

Finding The Perfect Temperature To Hot Tub In

Finding your perfect temperature will come down to personal preference, test it out! Keep in mind the below health considerations before doing so then you will be safe to try 40°C vs. 37°C!

Health Risks & Children

For children using the hot tub, the temperature setting gets more complicated and should be considered very seriously.

  • Always consult a doctor before getting in the hot tub while pregnant.
  • Children under age 5 should not be in hot tubs over 35°C, and should only remain in hot tubs for 5-10 minutes at a time for safety.
  • Make sure you stay hydrated while using a hot tub. 

 

FAQ’s

How Long Does It Take For A Hot Tub To Heat Up?

This varies depending on the size of your hot tub, the heater used, water capacity and the weather. Generally a hot tub will take between 16-24 hours to reach maximum temperature.

What Should I Do With The Hot Tub Temperature When I Go Away?

If you are definitely not going to be using your hot tub it may be worth lowering the temperature to save in energy costs. Some hot tubs come with an ‘eco-mode’ which will automatically reduce the temperature slightly at a set time. Or if it is going to be a while until you use your hot tub you can reduce the temperature to the lower end of the setting. Most hot tubs have freeze protection so there is limited risk of freezing in the winter if you do this. 

My Hot Tub Will Not Reduce In Temperature, What Should I Do?

In the heat of summer, sometimes the ambient temperature means that the hot tub temperature is very hard to reduce. You could try running your hot tub jets, which will add air to the tub and gradually cool it. Failing that the best thing to do is either partially drain and add cold fresh water to reduce the temperature or to leave the cover off for a period to bring this down.
