hot water tanks have a temperature setting, if your going to do something, do it right. I live in a large house with 2tanks, 2 baths. most toilets are not set up for true bidet functions. A bidet bowl is much wider, it also has cold and hot water valves .. Not everyone wants to step into the shower to property clean their bottom.. I like bidet bowls because it has a better than the tub, shower.. Id like to take one my toilets out and put in a bidet.
