Hot Tubs - Why?

What is it with Hot Tubs, why is it that they have become so bloody popular?

Everywhere I look there seem to be companies selling these glorified baths. The local papers always seem to have adverts for them.

So, I have to ask the question, who the hell are buying these things? After all it's not every home that can house one of these units, I know I certainly couldn't. I have enough trouble getting a bird table into my back garden, where the hell could I put a great big electric guzzling glorified bath?

I know they have benefits, especially for the old sex life, but surely some sexy underwear has to be cheaper than the electric bill alone?

So if anyone can convince me that Hot Tubs are nothing more than a fad, then please feel free to enlighten me.

Of the hot tub sites that I have seen the following have been head and shoulders above the rest.
