I love steam rooms. i want to build one out behind our house in the country in thailand. but it has to be low-tech. i'm thinking i'll make a square wall out of cinderblocks, about 4 feet high. then my shower will stick up from that .we don't have running water. we get water pumped from the well into big jars and use a bowl to splash water on ourselves to wash. but i put a submersible pump in the bottom of the jar, rigged up some PVC pipe and i have a shower of sorts. so if i build a 4 foot high square wall, with a doorway, i can pull a thick piece of foam over the top to cover the top, hang a rubber curtain across the doorway opening, and have an enclosed, outdoor room that i can steam up and sweat the gunk out, then stand up, flip off the insulating cover and shower right there. the steam room will go right behind me and the jars in the shower picture- where you can see a little bit of grass growing.
but how do i make a steam generator? commercial ones cost way more dollars (baht) than i need to spend. i can use propane from a tank for fire, or wood, or charcoal. the well water is very hard water with a lot of dissolved minerals in it so my steam generator can't be something that will get clogged up with mineral deposits.
anybody got any ideas? the steam generator needs to be cheap, home-build-able with local materials, and safe... don't want anything that can blowup, catch fire, or asphyxiate the users.
