    Love our sauna! Assembly was very straightforward, with easy to follow instructions. The sauna experience is everything we imagined. We visited Finland several years ago and enjoyed daily saunas, and were so impressed by the benefits we experienced. We've been searching ever since for the "right" sauna to replicate our experience. Redwood Outdoors checked all the boxes. Excellent value, excellent customer service, and excellent product!! We love it!

    I had an old infrared sauna that I've used for years and decided it was time to upgrade. After shopping around online trying to find a good setup I came across "Redwood Outdoors" and I really liked the style they had. The sauna was super easy to set up and the craftsmanship is excellent... It gets way hotter than my old infrared! The Pacific cold tank is equally impressive, looks great next to the sauna and the quality is impressive. It took me a while to get used to because it cools the water down into the 30's, but I use it every morning and its made a huge deference in my energy and how I feel throughout the day!
