The Hot Tub is the Perfect Place to Relax, but what is the ideal Water Temperature?

If you’ve just bought a hot tub for your loved ones to enjoy (or maybe for yourself! ), you may be eagerly anticipating your first dip. However, as a new owner of a spa, you may be unfamiliar with the optimal temperature range for your purchase. The question you may be asking is, ” At what temperature will I have the most fun?” You may have wondered about this. Yet, we regret to inform you that there is no easy solution to this conundrum. It’s true that everyone has their own special collection of interests and that these can even shift over the course of a year. Therefore, how do you choose? Our company is the most well-respected provider of spa services in Fort Collins, so we’ve come to offer some advice that you can use to ensure that your swim meet goes off without a hitch. 

These are our suggestions:



Precautionary Measures

I would want to ask you to keep the following things in mind as we get this discussion started. If young children will be utilizing the spa, or if any of your guests have medical concerns that could be made worse by immersion in water, you may want to consider lowering the temperature of the water to make it more comfortable for them. People who have preexisting medical conditions should not use hot tubs; as a result, it is imperative to get a doctor’s consent before bathing in one of these tubs. Hot tubs can cause serious complications for people who already have medical conditions. Women who are pregnant shouldn’t enter a hot tub without first seeing their obstetricians ensure that doing so is not only possible but also safe. Even after they reach the age of five, children should not remain in the water for more than five to ten minutes at a time, and they should never swim in water with a temperature that is higher than 95 degrees Fahrenheit. We repeat, children under the age of five should never swim in water with a temperature that is higher than 95 degrees Fahrenheit. It is never appropriate to leave a child unsupervised in a spa, regardless of the circumstances.

Those Who Prefer It Hot

Now, if you are anything like the hundreds of other individuals who enjoy utilizing hot tubs, the temperature of your spa is most likely set to a scalding 104 degrees Fahrenheit. This is because hot tubs are relaxing and rejuvenating. Underwriters Laboratories has determined that this is the highest temperature that may be tolerated in hot tubs. This is due to the fact that hot tubs heated to greater degrees can put their users at risk (UL). Users of hot tubs can be exposed to temperatures as high as 104 degrees Fahrenheit without having their comfort compromised in any way.



Adaptations to the Changing Seasons

There are some people who prefer to maintain the temperature of their spa so that it is consistent with the time of year or the conditions outside. For instance, during the summer you might like a spa that is warm, but during the winter you might like the one that is quite hot. Feel free to adjust the temperature of your hot tub in response to the shifting conditions in the surrounding environment. It is common practice to lower the temperature of your spa in the summertime so that you can use it as a “small pool” to escape the heat of the day during the long, sweltering days of the season. Even with the spa temperature turned all the way down to its lowest setting, the water can still be filtered.


If you really want to make the most of your time in the spa, keep in mind that temperature shifts, especially sudden or frequent ones, might be harmful. If you frequently adjust the temperature of your spa, you are causing extra wear and tear on its components, which in turn reduces the spa’s lifespan. You can avoid making repeated adjustments by gradually modifying the temperature range of the spa to correspond with the changing of the seasons.

When You’re Not Around

Before leaving for an extended period of time in the hot tub, it is only normal to wonder if it is worthwhile to lower the temperature of the hot tub. If you are going to be gone for a few days, you may save some money on your utility costs by lowering the temperature of your spa by five degrees and keeping it at that setting. After that, when you go back, you can easily bring the temperature back up to normal without putting too much strain on the hot tub because you kept it at a lower level while you were gone.


The temperature of the water in your bathtub can be maintained at an even lower level if you will be gone for longer than a week. You can reduce the temperature of your spa to its absolute minimum if it has a setting that helps you save money on energy costs or if you simply want to spend less money overall. If you keep the spa running at all times, the water in it will be maintained in a clean and filtered state.
