The TOTO T40 WASHLET plus Connelly Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and Classic WASHLET S7 Bidet Seat with AutoFlush is designed to conceal the WASHLET plus power cord and water supply hose for a seamless installation. The WASHLET S7 features TOTO''''s technologically advanced EWATER plus system that transforms water into a safe and powerful compound. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The TOTO WASHLET S7 is operated by a luxury style illuminated touchpad remote with sliding action and 4-user memory storage to save preferred settings. The WASHLET features 5 spray settings, heated seat, 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. The Connelly has a concealed trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. 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 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 ceramic glaze that minimizes waste from sticking to ceramic surfaces. CEFIONTECT, EWATER plus , 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. Compatible with T40 WASHLET plus toilet bowl components only.
