Compared to other leading brands I’ve tested, the Evolve 20 delivers a faster heavier sweat due to its 360 degree Infrared body coverage. It’s also the lowest EMF & ELF sauna I’ve tested. It’s truly exceeded my expectations!

Just took my first sauna [Evolve 20] and WOW! What an awesome IR Sauna! Easily 4 times as intense as my old Sunlight sauna. I love it!! I do strength training 2 times a week and sauna afterward. What a great after workout regimen! Day 3 of the new sauna and I’m obsessed with the intensity of the Evolve 20!! I’ve never sweated so much in a sauna in my life, bar none…. With my old Sunlight sauna, I could go 30 minutes at top temp with no problem and wouldn’t be near as sweaty.

I wanted to write to you to thank you for your wonderful Sauna. First I want to thank you for answering all my questions and calls , you are very knowledgeable and patient with all my questions. I have only missed 3 days in the last 2 weeks and the benefits I have seen already are a lot more than I expected . I had some Tendinitis in both knees and it disappeared after two 30 minute sessions. There is so many other things but I will run out or time. I looked at 5 different brands and talked to many different people about all the top brands and I still think this was the best buy for the money. I know there are saunas that cost a lot more but I don’t know why you would want to spend that much when yours works so well. Thank you!!!

I have been using the sauna [Evolve20] regularly and I truly enjoy it! I started to use the sauna about a month ago. Since then I have used it every night. After a long day I enjoy sitting in the sauna to detox and it almost feels better than a long workout. 5 stars on the assembly! I had no one to help me with the set up, so I was grateful that the sauna went together easily. It’s space friendly and looks great. This was an excellent investment and I am a 1000% a satisfied customer!

I finally got to truly try out the sauna. I love it! I sweat so much that I left a puddle on the floor. One of our patients who has used Infrared saunas before commented that this one [Evolve 20] was 1000 times better than what she has been paying to use elsewhere.

I am thoroughly enjoying the Evolve. I don’t think I sweat as much from even strenuous aerobics on a warm day! And far from being drained, I find myself loose, fresh, and energized afterwards. After four or five sessions, I noticed marked improvements in both deeper sleep and endurance in my workouts. Kevin, you should be proud of your design. I believe the Evolve is efficient, effective, and worth every cent. “Warm” regards,

I’m enjoying the Evolve more than I can describe in a few lines!! That front door heater cooks like a Louisiana barbecue. Once it hits 115 degrees F., (which doesn’t take long at all) I start to sweat. And within 3-5 minutes it’s at 120 F. and the toxins are pouring out of me. This has been the best money spent in years. And you were easiest CEO, owner, salesman I’ve ever had the pleasure to work with.

LOVE YOUR SAUNA! I used the sauna last night. I LOVE it very much. It was so relaxing especially after many days of dealing with the construction team. I cannot wait to use it again tonight.

The sauna is my favourite daily retreat. I use the sauna daily following physical activity to relax muscles. The sauna is very effective and sweat occurs within 10 mins. I could not imagine having the sauna without the door mounted heater design. It targets all areas needed and the warmth is comforting. ...really enjoy the essential oil diffuser and colour therapy for a relaxed setting. The benefits of detoxification and relaxation of muscles is very much valued. The craftsmanship of the unit is beautiful, making a nice addition to the bedroom where it is set up. I have recommended your brand specifically as I am very pleased with the quality and service.

Your saunas are gorgeous. The innovation in the Evolve actually took my breath away. The prices are excellent, especially given the quality. I am very impressed with the Sun Stream Infrared saunas, so it is no surprise that my son’s ND recommends them Thanks for making such gorgeous and effective products.

Yes, I have been using the sauna but of course! It’s great! I’m loving it and still can’t believe it’s actually here! I love the colour therapy and the stereo is working great! It seems to warm up super fast, faster than I expected compared to other saunas.
