wow.. that's a huge work. I watched the process because such things inspire me deeply. I don't have an opportunity to build my own real sauna now, but I made my dream (part of it, actually) come true by building a near infrared portable sauna, a few years ago. Now I use it in our bathroom, which is very small. I prop it up against the bathroom door once it’s closed. I then sit on my Squatty Potty and face the lamps. I rotate every 5 minutes or so in an effort to get my whole torso exposed. I sweat quite a bit just this way, but if I really want to sweat, I will also plug in a space heater and heat the bathroom up more so I can get more sweating in. I also do infrared with my CEs, but I use my single lamp unit and clamp it on the drawer next to the sink and lay underneath it..
