Years of relaxing to come!
Sep 19th 2024We love our Redwood Outdoors extra wide thermowood sauna. The instructions video was super helpful, my husband and I set it up in one day. We upgraded to the bigger heater as it gets very cold in the winter. We also used a blue hue light for night use. Looking forward to years of relaxing enjoyment!

Optimal design for heat lovers
May 5th 2024I have been using this extra-wide thermowood quite nearly every day for the past six months and it's worked perfectly. I like the upper back bench design because it really gives you the ability to get maximum heat, without cool legs like some other barrel saunas. I'm quite impressed. Would recommend.

Great Customer Service
Feb 16th 2024If you are still in your search for a company to buy your sauna from, look no further, you have found it! I was recently in your position and after researching many companies, I decided to order the Extra-Wide Thermowood Barrel Sauna - 6 Person from Redwood Outdoors. When the sauna arrived, it included Instructions that were clear and easy to follow. I would highly suggest two people to make assembly easier. After a few months of use there were a few minor quality issues that I addressed with the company, who promptly responded and addressed my concerns. I am SO glad that I ordered from this company, I would recommend them to anyone!
