A hot tub can be constructed from any container large enough to hold
you and able to tolerate hot water. When hot tubs first started becoming
popular in California in the 60's, the ideal tub was considered to be
an old redwood wine vat. People would scour the countryside looking for
these abandoned vats, dismantle them, and turn them into soaking havens.
Hence the popularity of the redwood tub in California.
However, the availability of discarded wine vats is limited, so fortunately
there are other possibilities. Actually, the possibilities are nearly
endless! For the relative novice, there are hot tub kits that come with
everything you need to construct a beautiful wooden hot tub in your home.
This is surprisingly inexpensive when you compare it to the prices of
the popular fiberglass Jacuzzi spas. Many hot springs enthusiasts prefer
the natural feel of simple wooden tub to these new fangled fancy superjet
models, because it feels more like a hot spring, and elicits a feeling
of tranquility in the soaker. One site that contains such tubs that you
assemble yourself is Robert's Hot Tubs.
I am sure that if you search, you can find others.
