Bought the construction plans and all materials needed. The plans were very well done, and easy to follow. I still need to finish painting the outside, and add some final touches.I also added a window to the design for my wife to not feel so claustrophobic. We have been using it since New Year’s. This is a great little sauna box and inspired me to create more of a traditional one on my deck in the future. If you’re a handy person, this is very easy and can be done in a couple of days. I would recommend this for sure.
