Can a Hot Tub Be Used with Cold Water?

Can a Hot Tub be Used with Cold Water
Hot tubs are definitely most popular in the cooler months, but with the warm rays of the summer sun fast approaching, many people wonder “Can a hot tub be used with cold water?” It’s an interesting concept and surprisingly possible. Let’s explain how you can enjoy your hot tub with cooler-than-average water temperatures on hot summer days.

When Can a Hot Tub Be Used with Cold Water?

First and foremost, it is important to understand that hot tubs are designed to be used with hot water. The average hot tub temperature is around 102°F (39°C), which is the ideal temperature for relaxation and therapeutic benefits. However, this does not mean that you cannot use cold water in your hot tub. In fact, there are some instances where using cold water may be beneficial. One scenario where using cooler water in a hot tub may be useful is during the summer months when temperatures are high. In these situations, the heat from the hot tub can be uncomfortable for some people. In this case, adding cooler water, or keeping the thermostat on the lower side of warm can help you enjoy an afternoon soak. Another scenario where using cold water in a hot tub may be useful is after exercising. After a strenuous workout, your muscles may be sore and inflamed. By soaking in a cold or cool hot tub, you can help to reduce inflammation and soothe sore muscles. This is because the cold water helps to constrict blood vessels and reduce blood flow, which can help to alleviate swelling and pain.

How Do You Keep Hot Tub Water Cold?

The two best ways to keep your hot tub on the cooler side are to keep the temperature low or to add a feature like Caldera Spas® CoolZone™. If you choose to simply lower your thermostat, just adjust your temperature settings. While the water may not reach what is considered “cold”, it can still make a difference in comfort on hotter days.  CoolZone on the other hand, works much like your home’s air conditioner, creating brisk spa waters as cold as 60 degrees. It can also work to warm your spa’s water, allowing you more control over your ideal temperature all year long. 

Things to Consider When Using Cold Water

It is worth noting that using cold water in a hot tub may also impact the chemical balance of the water. When the temperature of the water is lowered, it can cause the pH levels to change and may also impact the effectiveness of sanitizers. It is important to monitor the chemical levels of your hot tub regularly and adjust them as needed if you plan to use cold water. Overall, while most spas are designed to be used with hot water, there are instances where using cold water may be more comfortable and even beneficial.
