Easy Peasy!

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!

Amazing detail

This is the 2nd plan I've purchased (after purchasing the original cold plunge plan), and it's even better. Highly recommend!

New Sauna Build!

I just completed the XL Sauna build this week. I want to note my experience in building things is limited to none. Before I started using Joes plans I realized I almost had no tools! (Apart from being an IKEA assembly pro). Joes instructions were clear and simple to follow for a first timer.

I was able to complete the entire build in two weeks. And although it is not perfect (user error not the guide) it’s fully functional and works GREAT.

I really appreciate these guides, as my finances made it so I couldn’t purchase an ice bath or a Sauna, and the only good gym that had both was an hour away from my house. And yes, I did commute 3-4 days a week to said gym. Now I can go to my local gym 2 minutes away, and pop back home for my sauna and ice bath!

I highly recommend this guide to anyone. I wouldn’t fret if your a first timer when it comes to building, literally if I can do it anyone can!

Great plan! Easy to assemble step by step

I am 5’9” and I’d say if you’re a little taller go with the XL. I am very comfortable in it. I love the sauna it heats up to over 210F in 45 min. Was easy to assemble and I was able to save even more money where I could. Thanks Joe!

Awesome project

Very clear instructions that are easy to follow. The few times I had questions, he was very responsive and friendly. I love that he’d always ask for feedback on how it could be made better. You can tell he put a lot of time and care into this product.
