Someone once joked to me that everything you own takes batteries or plugs in. They were right of course, except for my toilet. Now that can change, although I can only imagine how expensive this is. Check out the Kohler Numi toilet. It includes features such as a full touch screen remote, self-cleaning wand, automatic opening/flushing/closing, heated seat, ambient lighting, speakers, water conservation features, and a bidet with a precision air dryer. Where do I sign up?
