The two-piece elongated dual flush toilet with autoflush is designed to conceal the washlet+ power cord and water supply hose for a seamless installation. The Washlet S500e features the manufacturer's technologically advanced Ewater+ system 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 sprays the bowl before each use to prevent waste buildup, keeping the bowl clean. The Washlet S500e is operated by a luxury style illuminated touchpad remote with sliding action and 2 user memory to save preferred settings. The Washlet features 5 spray settings, heated seats, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamlined look and giving the impression of an integrated system. The minimalistic display provides a more subdued appearance to your Washlet. This toilet has a concealed trap way, which enhances the elegant look of the toilet and adds an additional level of sophistication. 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 product features the manufacturer’s 3D Tornado Flush® a hole-free rim design featuring three powerful nozzles that generate a centrifugal, cyclonic rinsing action with the option of 0.9 or 1.28 gallons of water. The left-hand chrome trip lever allows the user to decide the right flush for the appropriate job. Choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. This version includes Cefiontect®, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. Cefiontect®, Ewater+, and 3D Tornado Flush® create a synergy that optimizes performance to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines.
