The best temperature for a hot tub is 100-102°F. This is the sweet spot for relaxation and stress relief. It’s also the best hot tub temperature for promoting the effects of hydrotherapy. So, to get the most from your hot tub – set the temperature dial to 100-102°F (37.8 – 38.9°C). Below we cover everything you need to know about hot tub water temperature.
What Temperature Should You Keep Your Hot Tub At?
You should keep your hot tub at a temperature that feels most comfortable for you. To get the most from your hot tub experience it is crucial you feel comfortable and choose a water temperature that suits your individual preference. At the end of the day – it’s all about relaxation and enjoyment. So, set the dial to whatever heat level feels right for you.
In general, the best temperature for a hot tub is 100-102°F (37.8 – 38.9°C). This is considered the temperature that works best for the vast majority of individuals. A hot tub temperature in this range promotes relaxation, stress relief, and boosts the effectiveness of hydrotherapy.
• Hot Tub Temperature for Adults
In general, the best hot tub temperature for adults is 100-102°F. However, anything above 90°F is good. If you find 100-102° to be too high – aim for something in the nineties. Choose something that feels comfortable and allows you to relax and enjoy your time in the hot tub.
• Hot Tub Temperature for Children
Aim for a lower water temperature for children. Children are more sensitive to heat than adults. And, to ensure a kid enjoys their time in a hot tub safely – you should turn the dial down a little. The best rule of thumb is to aim for a temperature that matches their skin temperature. This is usually somewhere in the region of 90°F. And, always make sure kids are supervised by a responsible adult when using a hot tub.
• When Consuming Alcohol
Let’s face it, hot tubs and parties go hand in hand. This means many of us will jump in a hot tub at some stage whilst consuming alcohol. But what about hot tub temperature and alcohol? Do you need to adjust the temperature if you are consuming a beverage? In short, yes.
If you are using a hot tub and consuming alcohol you should reduce the water temperature a little. Just turn it down a few degrees to reduce sweating and body temperature while you enjoy a cold beer.
How Do You Adjust Hot Tub Temperature?
Adjusting the temperature of a hot tub is easy. All modern hot tubs come with a control panel that allows you to adjust the temperature to your preferred level. Most control panels have digital displays. To change the temperate you can press a button to either raise/lower the temperature setting.
These buttons are usually marked as either up and down arrows or as plus and minus symbols. When you reach your desired temperature, press SET, ENTER, or OK. Once you have set your preferred temperature you will need to allow some time for the water to heat up to your chosen temperature.

How Long Does It Take a Hot Tub to Heat Up?
It takes approximately 8 hours for a standard hot tub to heat up from an ambient temperature of 50°F to 60°F to an operational temperature of 100°F to 102°F. However, the time it takes for a hot tub to heat up depends on several factors. These include the initial water temperature, the size of the tub, the efficiency of the water heating system, and the desired heat level chosen.
• Initial Water Temperature
The length of time it takes for the unit to heat up will be largely influenced by the temperature of the water in the tub when heating commences. If the water inside the tub is cold – it will take longer to reach the chosen temperature point. If it is a little warmer – it will reach the desired temperature more quickly.
• Hot Tub Size
The size of the hot tub also affects the amount of time it takes to heat up. Large hot tubs that hold large volumes of water take longer to heat up compared to smaller hot tubs.
• Heating System Efficiency
The efficiency of the hot tub’s heating system also plays a key role. Hot tubs with powerful and efficient water heating systems will heat up more quickly than devices with inefficient heaters.
• Desired Temperature
The higher the temperature you set on the control panel – the longer it will take to reach that temperature. Higher temperatures require more heat energy and this takes more time to achieve.
Safety Considerations
Hot tubs are safe to use for most individuals. Read your manufacturer’s user manual and follow the guidelines at all times. Below are some additional points to note to ensure you get the most from your hot tub session.
• Medical Advice
If you have any medical concerns about using a hot tub you should seek professional medical advice. This includes people that are heat sensitive, have underlying medical conditions, and women who are pregnant.
• Heat Sensitivity
If you feel too hot at any time you should climb out and allow your body time to cool down to regular body temperature. Never remain in water that makes you feel uncomfortably hot.
• Time Limit
In general, you should limit your hot tub session to 15-30 minutes to prevent overheating. Spending an excessively long time in a hot tub can lead to overheating and make you feel unwell.
• Child Supervision
If a child is using a hot tub they should be supervised by a responsible adult at all times.
• Safety Cover
When the hot tub is not in use you should attach a safety cover across the surface of the tub. Many hot tubs also have barriers to prevent access when the tub is not operational.
