The TOTO WASHLET+ Kit Connelly Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and Classic WASHLET S550e Bidet Seat is designed to conceal the WASHLET+ power cord and water supply hose for a seamless installation. The WASHLET S550e 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. The Premist function sprays the bowl before each use to prevent waste buildup, keeping the bowl clean. The TOTO WASHLET S550e is operated by a luxury style illuminated touch pad remote with sliding action and 2 user memory to save preferred settings. The WASHLET features 5 spray settings, auto open and close lid, heated seat, a nightlight, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamline look and giving the impression of an integrated system. The minimalistic display provides a more subdued appearance to your WASHLET. The Connelly has a concealed trap way, which enhances the elegant look of the toilet and adds an additional level of sophistication. The Connelly features TOTO’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 of the Connelly 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.
