This toilet by INAX USA has everything going for it. The lid lifts as you approach it. There's a built-in air deodorizer, seat warmer, light, and stereo. It flushes automatically. Two self-cleaning nozzles spray water with varying intensity to wash and/or massage the user. The only downside obvious in the photograph is a complete lack of privacy.
