Outdoor Infrared Sauna Benefits:

  • Relaxation
  • Improved circulation
  • Sore muscle relief
  • Improved sleep
  • Detoxification

Infrared heat is much more gentle than hot rock or steam saunas. Traditional saunas can create heat and steam in excess of 200°F, but infrared heat operates at the much more comfortable temperature of 100°-150°F while providing all the benefits you would expect from a steam sauna. There is also evidence that infrared saunas can boost collagen production and improve your mood.

Love the sauna

arrived fast, super easy to assemble. I later ordered an additional weather cover just so that I would have it when the other fades. Employees super responsive.

Thank you so much Sharon, we enjoyed working with you!

Quick customer service

"I'm giving 5 stars although the sauna came with a crack in the top ceiling. When I called the company they sent out the new part immediately with no questions asked, so I'm impressed so far with the customer service. The sauna works great on my patio and provides all the heat we need to get a good sweat going. It's hard to find an outdoor model at this price, so I'm definitely pleased with the purchase."
