We have them on both toilets. My wife LOVES them and I like them, too. Warm water? If you want that, spend the money for one with a heated tank. If you plumb in a hot line, you'll sit there with cold water turning your butt blue until the hot gets through the line. If you're a ways from the water heater, that can be a long cold wait. I just turned the hot off. It only takes a few seconds to hose it down and it isn't worth the cold wait for hot water.
