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

Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.

Where you drain a hot tub largely depends on local regulations, but you must not drain chemically treated water where it can damage the environment. Direct the water toward a sanitary sewer drain that will take it to a treatment facility. If your lawn has a dedicated drainage area that’s free from plants and foundations, you can likely drain it there. Avoid storm drains, as the hot tub water will enter waterways and could hurt aquatic life. Likewise, do not pour it out directly on any public land or where it can get into your neighbors’ property. 

Vinegar can be used as an all-purpose cleaner for many things, including hot tub filters. Soaking hot tub filters in vinegar and water for up to 24 hours can remove dirt and oil, and as a bonus, it won’t cause the water to foam after you reinstall it if there’s vinegar left on it. But make sure you still rinse it to remove any debris, dirt, or grime stuck on it.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

Yes, hot tubs are meant to be kept on permanently. It takes more energy to ramp up a hot tub when you turn it on, so leaving it on all the time is more efficient for your hot tub. You can turn the temperature down if you know you won’t be using it for an extended period of time to save on energy costs.
