Maintaining the Ideal Hot Tub Temperature

When you’re ready to climb into the hot tub to warm up, to melt away tension, or to spend time with loved ones, you want it to be ready for you. You don’t want to have to wait. Otherwise, what’s the use of having a hot tub at home? While in-ground hot tubs, which are traditionally kept uncovered at all times, are difficult to maintain at a constant high temperature, it’s easy to keep portable hot tubs heated and ready for use.

The best way to prep your tub so it will always be ready is by spending some time finding your most comfortable settings. Believe it or not, the best way to approach your preferred hot tub temperature—for the life of your spa, for your convenience, and even for your wallet—is to set it at that temperature and keep it there.

What Is the Ideal Hot Tub Temperature?

While the ideal hot tub temperature varies from person to person and depends on factors such as age and personal preference, there are some recommended standard guidelines that are important to observe. Here are some helpful tips to help you find the ideal hot tub temperature for yourself and your family:

  • Don’t Exceed 104 Degrees for Adults

The US Consumer Product Safety Commission has determined that temperatures above 104° Fahrenheit (40° Celsius) are dangerous for adults because they can lead to heat stroke. In general, people are most comfortable with temperatures between 100° and 102° (37.5–39°). Adults are safe to soak at these moderate temperatures for twenty minutes at a time.

How to Find Your Ideal Hot Tub Temperature

When you’re scouting out your personal ideal hot tub temperature, it’s best to start low, as it’s easier to bump it up than to bring it down once you’re already uncomfortable. Set the controls to 98° or 99° and increase it in gradual increments depending on your comfort level. It’s important to listen to your body and to get to know your personal comfort zone. If you have more than one person in the tub at a time, set the temperature to the lowest preferred—or lowest recommended—temperature of everyone in the group.

There may be times when you’ll want to proactively decrease the temperature by a few degrees—or by many degrees, if you’re recovering from strenuous exercise. Consider lowering the temperature of your tub in advance if any of these circumstances apply:

  • You’re planning to build up your own body heat in the tub through physical activity like stretching or yoga.
  • You’re already overheated from activity, illness, or a particularly hot day.
  • You’re inviting children or other heat-sensitive individuals into the hot tub.

Your spa can even become a refreshing soak during warm summer months if you turn the temperature down well below the average body temperature. Some hot tubs are capable of lowering the water temperature quickly and efficiently by using a system such as the CoolZone, which can be an especially welcome and refreshing option in warmer climates. In general, it’s simpler and more efficient to leave your hot tub constantly set to your desired temperature than it is to lower it when the tub is not in use. This is especially true for today’s advanced and energy-efficient models, which feature insulated shells that prevent heat from escaping and close-fitting insulated covers that protect your spa from outside elements.

You now have everything you need to start exploring your ideal home spa environment. If you have more questions about finding the right hot tub temperature, your knowledgeable local dealer has the answers. You’re well on your way to a blissful soaking experience.
