The majority of hot tub users prefer a water temperature in the range of 100°F-102°F. 104°F is the standard maximum temperature, which some users also prefer.
Hot tub water temperatures should never exceed 104 degrees Fahrenheit. A temperature of 100 degrees is considered safe for a healthy adult. Special caution is suggested for young children. Excessive drinking during hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.
Set temperature at or below 104 °F degrees for adults.
The US Consumer Product Safety Commission has determined that temperatures above 104 °F (40 °C) are dangerous for adults because they can lead to heatstroke. For a comfortable soak, most people set their hot tub between 100 °F and 102 °f (37.5 °C - 39 °C).
If you are doing warm water therapy with rehabilitative movements, 98.6 degrees is the temperature that most people prefer. Those who are recovering from an accident or stroke find 88 to 92 degrees to most comfortable. At the end of the day, whatever feels comfortable for your body is the ideal temperature.
Between 98 and 104 degrees, longer soaks up to 15 minutes are okay. A helpful safe practice is having kids avoid full body immersion, using higher “jump seats” that keep more of their body out of the water while spending time in the hot tub.
For healthy adults, the water temperature of a hot tub should not exceed 104 degrees. But if you have young children or pregnant women using the hot tub, you'll want to consider their safety as well. The U.S. Consumer Product Safety Commission recommends a hot tub temperature of just 100 degrees for pregnant women.
Hot tub lung is an emerging disorder caused by exposure to Mycobacterium avium complex (MAC) organisms contaminating hot tub water. The description of this disorder has been limited to several case reports published since 1997.
The ideal hot tub temperature for periods of non-use is around 95°F (35°C). This setting is energy-efficient while ensuring that the water remains at a level of warmth that avoids excessive cooling. Lowering the temperature when the hot tub is not in use helps conserve energy and reduces operating costs.
You may find that your hot tub won't heat past 99 degrees and perhaps only heats up to 84 degrees. This is often due to the filter becoming clogged and dirty, making it necessary to replace the part. The filter is fairly easy to remove and clean out if it has a reusable design.
Finding the right level will be different for everyone. Some people like their spa really hot but most prefer the water setting to range between 37 degrees and 38 degrees. If you are new spa owner, try adjusting the water temperature to around 36 degrees before you get in the spa.
How Low Can Hot Tub Temperature Go? The lowest safe hot tub temperature is around 85°F (29°C), perfect for cleaning or cool summer soaks—sometimes called the minimum hot tub temperature.
Some will go to as low as 98F, but going much less than that, let's say to around 93-94F (34C) means you're nearing the lowest recommended hot tub temperature, despite temperatures that still sound warm.
The ideal hot tub temperature typically ranges between 100°F and 102°F (38°C and 39°C). For summer, some prefer a cooler range of 85°F to 95°F (29°C to 35°C), which is refreshing yet still warm.
Most hot tubs must be connected to 240V electrical service, but some offer the option of operating on either 120V or 240V. While connecting to 120V can be less involved, most customers prefer the benefits of the 240V spa, which include quicker heating time and better temperature maintenance during cold weather use.
Spa pools shouldn't have a temperature of below 37°C (98°F), so yes, 32°C (90°F) is definitely too low. At 35-36°C (95-98°F) you still have refreshing warm water bubbling in your hot tub. Depending on the ambient temperature, you can switch off the heater, turn on the water jets, and wait for the water to cool off.
Use your hot tub's jets when heating
So, if you can, try activating your jets in bursts during the heating process to help speed things along.
Set your tub as low as 85° F for an ideal summer hot tub temperature. Because 85° F is cooler than the average body temperature, you'll feel an optimal cooling effect. Using a cover on your hot tub when it's not in use and keeping it shaded when in use will help with temperature control.
How Long Does it Take to Warm up a Hot Tub? Our answer for most hot tubs is that it takes about 3-8 hours. We get asked this a lot, and we have figured this out by the sheer number of hot tubs we have set up in our stores and put on display over the 40 years we have been in business.

The CPSC advises to never exceed 104 degrees in your hot tub. Temperatures of 106 degrees or higher can potentially lead to heat stroke. For your safety, your Bullfrog Spa will not allow you to set a temperature above 104 degrees.
Hot tub folliculitis is an infection of your skin's hair follicles caused by Pseudomonas aeruginosa, a type of bacteria found in many hot tubs and pools. The condition often clears up on its own in one to two weeks without treatment. Call your healthcare provider right away if you develop fever or if symptoms worsen.
Heat. The heat provided by hot tub water can help reduce swelling and the buildup of fluids in the body's tissues which are characteristics of painful inflammation. This can help improve the flexibility and mobility of joints affected by arthritis while decreasing the pain experienced from moving about.
Some people have developed Hot Tub Lung related to contaminated water in whirlpools, swimming pools, spas, saunas, showers and humidifiers. What are the symptoms of Hot Tub Lung? The most common symptoms are cough and shortness of breath. These symptoms often occur soon after exposure to the contaminated water.
