The Electronic Bath Water Cleaner. Kind of like a pool cleaner for your bath. Without the chlorine. Or dead flies. Contains a negative ion ceramic ball, far infrared generator, active carbon filter and an anti-bacterial agent. Not only that but it maintains the water at a constant temperature via a circulating pump. Genius. The only slight…ahem…worry, is having all that electricity hovering so close to delicate and extremely naked anatomical bits. But who dares wins, eh? Around $445.00 yen-wise.
