Hot Tub Water Temperature – SpaCap

If you own a hot tub you already know how great it is, all the health benefits and reasons to use it. However, you want your spa to be comfortable and safe for your family and guests. Today we hope to cover the most optimal temperature for your spa water.


Most hot tubs at hotels and other places open to the public are set at a standard of 104 degrees Fahrenheit. Residential hot tubs typically come set between 100 to 102 degrees.


Naturally, it is largely a matter of personal preference and there will always be others who want their water hotter or colder.


People interested in saving money on their power bill during the winter months, may want to set their hot tub to a lower setting since the weather outside will typically be colder and make the water feel plenty warm.

Those that use the hot tub for therapy may require a higher setting. In those instances you can raise it to 104 degrees which is the highest setting for any new spa commercially available. This is in accordance with the National Spa and Pool Institute’s finding that 104 has been determined as the highest safe water temperature for healthy adults.


Most hot tubs intended for home use allow for a water temperature setting between 80 and 102 degrees. But what feels comfortable to one person may seem unbearably hot to another. Although you may feel that the temperature setting on your hot tub is a matter of personal preference, there are some physical signs that our bodies send us to be aware of. Below are a few of the ways our body lets us know that we may be getting too hot along with the problem if you don’t pay attention.


  • Lower heart rate. Like many things this is one that sneaks up on us because relaxation itself will cause your heart rate to slow down. The problem is that for some people, the heart rate slowing down too much can be deadly. The warm water of the hot tub will slow your heart rate as you relax and your blood vessels dilate. If for any reason you start to feel light headed or you notice someone else showing signs of it, it’s time to get out of the spa and cool down.


  • Vasodilation. As I mentioned above the hot water will cause blood vessels to open up, especially those close to your skin. Although great for increasing blood flow to extremities and for decreasing blood pressure, it too can be a problem. People suffering from heart problems or chronic low blood pressure should be careful to limit the time they spend in the hot tub. If it’s your hot tub and you want to be able to spend a longer time soaking, this would be one of those times setting the water temperature lower would be a good idea.


  • Dehydration. Actually this one is way more common than you might think. Especially among those of us that think the hot tub is a perfect place to enjoy an adult beverage. While you’re enjoying the soothing sensations of the hot spa water you’re sweating. We just don’t realize it because we’re sitting in the warm water. Plus, and this one is even harder to wrap your head around, our skin is drying out. You’re becoming dehydrated while you’re sitting in hot water. Crazy right? But it’s not a joke. If you don’t keep hydrated (and no alcoholic beverages don’t count, in fact they make it worse) you could end up with a headache or some other more serious effect of dehydration. So for the safety and well being of yourself and your guests keep drinking plenty of water, before and during your time in the hot tub. Save the adult beverages for after your spa time.


It would be irresponsible of us not to mention that if you are concerned about heart complications or any other health risks, it would always be better to consult your physician. Maybe the doctor can suggest a safe hot tub temperature for you.


We want everyone using a hot tub to be safe which is one of the reasons behind the design of our lightweight hot tub covers.


Years ago when we would travel to home shows all over the country, in our display we would have a video set up showing an actor being injured by a heavy foam cover slamming down on them. It would run continuously during the home show. Eventually, invariably a visitor to our booth would tell us that it had happened to them.


Heavy hot tub covers can be a more than just annoying, they can be a serious hazard. That’s why the covers we build at don’t use foam panels like the typical rigid hot tub covers. We use air chambers to do the insulating instead. Aside from being more efficient, the air chambers don’t suck up moisture like every foam-filled cover ever made.


Why not order a custom SpaCap spa cover for your hot tub today and save yourself the aggravation of wrestling a heavy cover.
