Heat therapy goes back to ancient times as a proven way to help people relax and unwind. The stress of daily life drips out of each pore as tired muscles detox and recover. Saunas are today’s solution to individual heat therapy. New technology and precision design make it possible for you to own a personal sauna in your home.

Our team take into account the features you want, the best size for your space and cost. Great Bay offers both custom options and a variety of pre-built saunas, which include:

Helo Modular Saunas

These freestanding units can go almost anywhere. You get the look and feel of a built-in sauna with the flexibility for easy movement. They’re a great choice for people renting their homes or those who expect to move. Helo Modular Saunas can also add a little luxury to a workspace. Check out the Prestige Series as well as Panel-Built options.

Helo Infrared Saunas

Working a bit differently, thanks to technological advances, infrared units give you the benefits of heat therapy at a more comfortable temperature. Infrared heat penetrates deeper into the skin and muscle tissue at a lower temperature. Helo Infrared Saunas offer the most features at the best value. They’ve set new standards for infrared saunas around the world. Check out the S-Series and B-Series when you come visit.

Helo Outdoor Saunas

If you already know you want your unit outdoors, we have the best selection in the Northeast. Designed for easy assembly, Helo Outdoor Saunas are available in both the Patio Series and Suburban Series. Each high-quality option offers customizable design features and sizes. You’ll find the perfect sauna for your outdoor space.
