The Washlet® B100, TOTO’s newest addition to the Washlet family, is designed to fit on our most popular elongated toilet models. With the touch of a button, a nozzle extends from under the seat for soothing warm-water cleansing, virtually eliminating the need for toilet paper. The nozzle, which selfcleans before and after every use, can be set to move back-and-forth for maximum comfort and optimum cleansing. The specially designed contoured seat is also heated to provide maximum comfort.
