I have always wanted a steam bath, but I never wanted to pay 3500 to 7000 for one. So I got bored and tried to make one. It turned out good, very simple, lots of steam, but only for an outdoor environment. It is also very portable, so its easy to pack up and take to the cabin!
Step 1: Materials
1 large stock pot with lid
1 10' length of 1/2" inside diameter automotive heater hose
various plumbing fittings (I dont know what they were called, i just went to the hardware store and looked for what will work)
1 hose clamp
1 tent or similar (I used my hunting blind to try it out)
