Heavenly Heat Infrared Saunas are made for the chemically sensitive. That means that our infrared saunas create an ideal, safe, and effective detoxification environment for anyone seeking to eliminate toxic substances from their body.

"I purchased a Heavenly Heat Sauna a few weeks ago . What I liked is you don?t smell any glues . I also liked its easy ( two man ) assembly. What I don?t like , in order to avoid using glues, they use pins or very thin nails. Some pins were missing and some were not beneath the surface. For the rough edges you?re provided with a small piece of sandpaper . Bot at a cost of over 5k you don?t expect to do sanding. My biggest complaint is that it takes almost an hour to get the sauna to 150 degrees. Definitely not worth the price. "

Pool and Spa Servicing questions, answered by experts

Using bubble bath, bath oils, bath salts, or moisturizing products that contain butters or oils can damage your jetted tub. Because of the water pump and jet mechanism, you need to be more selective with products for a jetted tub than you would for a traditional bathtub in order to keep it functioning properly and avoid expensive repairs. These products also leave residue that can feed mildew and mold, so it’s best to avoid them.

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. 

If you want to have a chemical-free spa, or if you are wondering how to keep your hot tub clean naturally, there are several options. Some individuals choose to run their hot tub without treatment at all and simply clean it more often (although you risk bacteria, fungi, and algae growth if you take this route); others use natural products like vinegar or Borax. Ozone, ultraviolet light, and electrolysis systems are also eco-friendly ways to have a clean hot tub without chemicals. Saltwater hot tubs are popular with people who are sensitive to chlorine, bromine, and other traditional hot tub chemicals.

No, you cannot clean your hot tub filters in the dishwasher. While it may seem like a good idea, the dishwasher soap isn’t gentle enough for hot tub filters and can damage them. Gentle cleaning is better when cleaning the hot tub filters and keeping them intact.
