As a devout environmentalist, probably my greatest acts of heresy result from my love of Jacuzzis and whirlpool bathtubs. We had a tub at another house and hated to leave it. We just finished installing a new one here and my oh my, what a great thing. The whirlpool tub is really a great compromise between a standard tub and a full size jaccuzi. As long as you don't go overboard and put a small swimming pool in the bathroom, the energy consumption is minimal, there is little to no special maintenance. And they function better that a full sized unit since all of jets are directed at you. I have never found anything short of morphine that is more relaxing. And they don't even cost and arm and a leg anymore. We bought a very affordable American Standard tub that is perfect for our needs.
