The general rule of thumb is to lower it by about five degrees when you know you’re not using your hot tub for an extended period of time. With only a slight decrease in temperature, it will be easier to increase it to a desirable level when you’re ready to get back in the water instead of starting from scratch.

It’s easy to keep your hot tub clean and safe for all to enjoy by following a few simple tips:

• Make sure anyone who uses the hot tub rinses themselves and their swimsuits off, perhaps in an outdoor shower near the hot tub. 

• Don’t add anything to your hot tub’s water. Bath oils and bubble bath liquids might seem like a fun addition to your hot tub experience, but these substances will turn the water in your tub foamy and its surfaces hard to clean. 

• Restrict eating in the tub to light snacks that you can easily clean out if there’s any spillage. Crumbs from crackers and chips can be difficult to pick up. 

• Make it a no-pet zone. Pet fur and dander can pose a cleaning issue, but it’s also not a great idea for your pet’s health and safety. 

Similar to a hot tub, swim spas last anywhere from five to 20 years, depending on quality and your attention to maintenance. The best way to increase the lifespan of your swim spa is to carefully maintain it—including draining it around every six months to deep clean the parts.

If your hot tub is well-maintained, covered tightly, and the water is balanced and sanitized correctly, it can remain unused for up to two weeks without significant issues. Beyond this period, the water quality may start to deteriorate, potentially leading to the growth of algae and bacteria. However, it's crucial to note that this timeline can change due to factors like water temperature, sanitation levels, and the quality of your hot tub cover. Regular maintenance and water testing are essential to ensure the water remains safe and clean during periods of inactivity.
