Great Weekend Project

I'd been looking to get a sauna for quite some time, but space and cost were a concern. When I saw these plans I knew I had to try building one myself. It took me a few weekends to put together (I'm no expert craftsman) but just finished up today and very pleased with the results/look. I also purchased the DIY heater kit which was very simple to assemble. Even with purchasing some additional tools, this build only cost a fraction of what I was gonna spend on similar saunas online. Glad I went this route.

Elite!

I went with the XL build and it is extremely spacious! It also heats up a lot faster than what Joe posted (I live in the south and got it up to 180 in 45 minutes). The plans were very easy to follow and Joe was always available to help!

Fun to build. Great to use!

Joe made a great set of plans to follow. Without much experience my DIY Sauna turned out just as I wanted.
Thanks Joe!

DIY sauna

I just completed my DIY sauna build.
Joe had great instructions along every step of the way. He obviously put a lot of time planning this out.
I’m super excited to have a sauna in my home at a fraction of the cost.
Thanks Joe!
