This was such a fun and easy build! I just finished my DIY Stock Tank Cold Plunge using Joe's plans this winter( which turned out amazing), and was stoked to start this Sauna build. I'm not particularly handy, but Joe's instructions and step by step videos for the sauna truly made it fool proof. I opted to use the same cedar tongue and groove for the interior on the exterior ( additional 4-5 packages) and I think it looks beautiful! If you're sceptical, trust me, this is something everyone can do. The DIY heater kit performs amazing, and I love the WiFi controls. My DIY Cold Plunge and Sauna sit next to each other in my basement, I use them both daily and am so proud of what I built thanks to Joe!
