The new Drake® 1G® Washlet®+ Dual Flush Elongated Two-Piece Toilet with High-Efficiency Flush (Seat Included) with a contemporary washlet® bidet seat is designed to conceal the washlet power cord and water supply hose for a seamless installation. The washlet features Toto's ewater® system which uses electrolyzed water generated by a technologically advanced process that transforms 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. The premise function further helps keep your toilet bowl clean by spraying the bowl before each use to prevent waste buildup. 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 1.0 GPF for tougher jobs. This version of the drake includes Cefiontect®, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. Cefiontect, Ewater+, and 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 hidden connection on washlet+ models provides a streamlined look and gives the impression of an integrated system and the universal height design allows for a more comfortable seat position across a wide range of users.
