Toilet 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 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 e water+â® 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 s500e washlet features 5 spray settings, a heated seat, instantaneous water heating, and more. The Toto washlet s500e is operated by a luxury style illuminated touchpad remote with 2 user memory to save preferred settings. The new auto flush kit provides a hands-free automatic flush after every use. No need to touch buttons or handles, and never worry about someone forgetting to flush. 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 1.6 GPF for tougher jobs. The hidden connection on washlet+ models provides a streamlined look and gives the impression of an integrated system. The drake comes ready for installation into a 12" rough-in and is compatible with washlet+electronic bidet seat and toilet bowl components only. Additional items needed for installation must be purchased separately: toilet water supply lines. Includes hardware, wax ring, toilet mounting bolts, and toilet bolt caps.
