Solar Hot Tub Soaking 

In Hot Tubs and Motorcycles, I promised to show you how to make your own hot tub. If you begin tomorrow, you can be soaking in fresh, 103˚ water by evening. In almost every way, my new sun-powered tub is superior to the old redwood tubs of the 70s. Here is what you do:

 Babushka Dolls 

Go shopping for a metal livestock water trough: On the Internet, I discovered that water troughs come in slightly different sizes so they can fit inside each other for shipping – like Russian Babushka dolls.

Water Trough Shopping 



To my surprise and delight, our local “Hacienda Hay and Feed” farm supply had a yard full of metal water troughs. My brother made a livestock tank hot tub long ago and suggested that a long skinny tub was a lot better than a big, round one. It took less water and would heat up much faster. Since this would be just for Carol and me, I picked the biggest oval of the stack, which turned out to be over 6 feet long and about 2 feet by 2 feet on the inside. It is rated at holding 169 gallons. $200 later it was in my trailer, heading home.

These tanks are galvanized. You aren't supposed to heat galvanized metal because the fumes it releases are toxic.

Galvanized metal emits toxic fumes when heated.
