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.
