Amazing end product, Rock solid build plan.

Joe does a very good job of laying out the details step by step. You literally can’t screw this build up. The videos that come along with the build are great, I referenced this the most. I learn better by watching then doing. Overall I am super happy with my end build. I also got the heater kit that Joe makes. Fraction of the cost of the other big name products but in my opinion is far superior. Rock solid build plans from the get go. I am very happy with everything. Keep up the good work Joe!!

Fantastic Sauna!

Joe has done a fantastic job of covering every step of the build. Super easy to follow and a fantastic finished product. The list of components and parts and links for where you can buy them are extremely helpful.
