I chose Sun Stream for their Ultra Low EMF's & toxic free materials, I also sweat faster in my Sun Stream than I have in other Infrared saunas I have used in the past.

Hi Mark, I just wanted to tell you how much I love this sauna! I had a FIR cedar sauna about 7 years ago, which was similarly priced at the time. This sauna is far superior in my opinion, in terms of quality build and materials.

Thank you we have received our sauna on Saturday. Wow!!! I’m in love, and have enjoyed 2 days of relaxation just me and the heat.

Sauna is working perfect ... we are truly amazed at how well everything works and how great the sauna feels when it is -30 Celcius outside

Its been six months and I use the sauna regularly. The construction is solid throughout with the clear grade basswood and electrical hook ups fitting together with precision. The design of this sauna is simple and attractive and has been a great addition to the bath area.

I feel the heat is necessary for the dancers. Using the sauna to warm up before a rehearsal, before a treatment or a workout adds to the effectiveness of their overall program that I have set up for them. It’s a great addition to the rehab programs and the maintenance of proper health for the dancers at the National Ballet of Canada.

...all the heaters measured low EMF. I was very pleased with that finding. In checking other companies where they have advertised that their heaters gave out low EMFs when I put them to the test some were actually over 100 mG. I love how the wooden grids come off to clean the floor heater and wall heaters if they get splashed with sweat. It’s easy for my staff to go in, wipe them off and keep the sauna sanitary.
