Japanese toilets have a variety of features that render going to the bathroom more comfortable. Heated toilet seats, automatic flushing, and air dryers are only a few of the choices available. Electric or non-electric, in-tank or hybrid options are available. A bidet toilet combo is a piece of equipment that incorporates the functions of a toilet and a bidet into a single device. Some are meant to connect directly to your plumbing system and provide warm water in the same manner as your bathroom faucet.
