I live in downstate Michigan and went to college in the UP met a whole crew of Finlanders and was introduced to the Sauna! and its pronounced SOuna not SAWNA but i still slip from time to time if you arnt a yooper it takes time.
I graduated and moved back downstate for work but my life was lacking because i no longer had access to the "poor mans medicine box" so naturally i want to fill that gap. Research began to see my options for having my own sauna. Student Loan debt is a mother sucker and takes up a large portion of my income so $$ was tight so building looked better than buying and of course is much more rewarding.
I searched the web and found a few things but nothing really helpful for building a finish style wood burning sauna. I am getting into woodworking its becoming my after work hobby and this was the largest project i have done and still have a few things ill get to at some point. So I winged it at times but at the end of the day the sucker works as intended.
Step 1: The Stove
I wanted to keep the building small and fit 3-5 people so to save space I made the choice/mistake to have the tank sit upward. I went to the hardware store and purchased 8ft of 6" single wall stove pipe. Which i cut a hole smaller than the pipe in the tank using an angle grinder. Lots of sparks and loud but pretty fast work.
I made a door in the front and used steel banding and sheet metal screws to attach the strapping and door hinges. Because the tank was vertical not horizontal i had to create a baffle to keep the fire in the fire box and not in the stove pipe! So i used a piece of plate steel and some bolts so i could adjust the air gap to the optimize draw but still keep the fire in the box.
Note: in the picture u will see a piece of air duct on the tank this is galvanized and a big NO NO for a chimney end up with zinc poisoning but it is 6" and worked for a demo fit. I made a cage for the rocks using steel shelving.
I put on a section or 2 i believe of stove pipe and balanced it while i tested the baffle until i was happy. I was getting results i wanted and was ready to start building the frame for my sauna shed.
