Don't be silly. I've got a showerhead with a shutoff valve. I turn it on to rinse, turn it off to soap up and scrub. Yes, we live in a drought-prone area. But I've also realized that trying to soap and scrub yourself while the water is running is self-defeating. You can't work up a decent lather when the suds keep rinsing away. If you like the "spa effect" of constantly running hot water just for the comfort or the sensual thrill, that's your thing. But if your main goal is to get thoroughly clean, you can do it comfortably with a lot less water.
