Getting the temperature right in your hot tub can enhance your experience—or leave you feeling dizzy, dehydrated, or uncomfortable. So, what’s the ideal hot tub temperature?
Here are some safety and comfort tips to consider when determining what the best hot tub temperature is for you, your family & friends:
Safe & Comfortable Range
The recommended hot tub temperature is 100°F to 102°F (37.8°C to 38.9°C). Most people find this range soothing and safe for extended soaking.
Maximum Allowed Temperature
Health Canada and most spa manufacturers set the maximum safe limit at 104°F (40°C). Going higher can increase the risk of overheating, dehydration, and cardiovascular stress.
Adjust Based on User Type
- Children (5+): No hotter than 98°F; limit soaks to 10 minutes
- Pregnant women: Consult a doctor first; most recommend 100°F max
- Elderly or those with health issues: Stay at or below 100°F
Cool It Down for Summer
Sometimes you might want to cool off – especially in the Summer months. In warmer weather, enjoy cooler soak sessions at 95°F or even 90°F. This is also ideal for post-workout recovery.
Night vs Day Soaking
Time of day can be a factor to getting the best experience from your hot tub. Evening soaks can be slightly warmer (101–103°F) to help induce relaxation and sleep, not to mention evenings are often colder in general. For daytime use, you may be more comfortable at 99–101°F.
Pro Tip: Always hydrate before and after a soak, and exit the tub if you feel lightheaded, overheated, or short of breath.
Overall, differences in age, tolerance, time of day and season are all factors to setting an ideal temperature for your hot tub soak. Be sure to consider these factors a few hours in advance of your soak to provide optimal time to achieve the desired temperature.
