The new Drake® Washlet®+ Dual Flush Elongated Two-Piece Toilet with High Efficiency Flush (Seat Included) with contemporary auto flush washlet bidet seat is designed to conceal the washlet power cord and water supply hose for a seamless installation. The washlet features Toto's technologically advanced ewater® system which uses electrolyzed water generated by a technologically advanced process, transforming the water into a safe and powerful compound. By misting the bowl after every use, the ewater+ technology helps to keep your toilet bowl clean and hygienic without any extra harsh chemicals. Toto's advanced premise technology prevents toilet bowl waste buildup by using the incoming water supply to spray the bowl before every use and help keep it clean. The Toto washlet s500e is operated by a luxury style illuminated touchpad remote with 2 user memory to save preferred settings. The washlet features 5 spray settings, heated seat, and instantaneous water heating. The redesigned washlet lid style resides flush with the toilet bowl, providing a streamlined look and giving the impression of an integrated system. The new auto flush kit provides a hands-free automatic flush after every use. This version of the drake includes cefiontect®, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. Cefiontect, ewater+, and Dynamax tornado flush create a synergy that optimizes flush performance to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the drake inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The left-hand chrome trip lever allows you to proactively conserve water by choosing between a 0.8 GPF rinse or 1.28 GPF for tougher jobs.
