I’m a 100% noob when it comes to working with power tools…. And even I built this with just a few weekends of free time. Trust me, if I can do it- then YOU can do it. Joe lays every step out on paper AND video, so you can’t hardly mess it up. I brought my iPad out to the garage and just watched 2-5 min sections of the video, focusing on one step at a time. Most of my cuts were far from perfect, and my XL sauna still turned out great. I bought the heater kit too, and same deal- the step-by-step instructions make it dummy-proof. Highly recommend.
