TOTO's CEFIONTECT adds a layer of exceptionally smooth glaze to the bowl that minimizes waste from sticking to the ceramic. No need to touch buttons or handles, and never worry about someone forgetting to flush. Includes the WASHLET S5 electric bidet toilet seat with built in night light, 3 adjustable spray settings, heated seat, 4-user memory storage settings, and warm water reservoir. Settings are controlled on a conveniently attached arm control panel. TOTO WASHLET helps to reduce the need for toilet paper, saving trees and water used to manufacture each roll.
