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. "

1939. Yep, that's when it all began for us. Just a little water treatment business in the middle of the United States. Back when Franklin D Roosevelt was President, milk cost 49 cents and televisions started selling for the first time in America. Skip ahead 2 decades and a young man by the name of Darrell (Robbie) Robinson traveled from Chicago, Illinois to Rapid City to run this growing water treatment business and raise his family. Fast forward another couple of decades and the growing water treatment business was now booming with sales of swimming pool equipment and construction. Soon after with the popularity of hot tubs Robbie started the Pool and Spa Center. And so we were blossomed from a water seed! Over the past few decades we have remained family-owned and operated by second and third generations. As a company we have grown and moved around town, survived the 1972 flood and have still continued to serve our customers with the same standards and customer service as when we began back over 70 years ago. From all of us at the Pool and Spa Center, we strive to take care of our customers the best way we know how and to offer the highest quality products at a reasonable price. We carry the following products because we feel that they are superior quality and are innovators in their industry backed by exceptional customer service. We proudly serve Rapid City, SD and the Black Hills as well as Gillette and NE Wyoming with over 70 years experience.

Pool and Spa Servicing questions, answered by experts

Though a hot tub has many benefits, there are a few cons. Mainly, hot tubs require a lot of maintenance. You’ll need to deep clean yours quarterly, test the pH at least once or twice a week, and add sanitizing chemicals once a week. They also have relatively high ongoing costs since you’ll need to pay for electricity and repairs. 

Yes, they provide full-service inspections, identifying and resolving any potential equipment problems.

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.

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.
