The TOTO® AP Wall-Hung Elongated Toilet with Contemporary S7A Bidet Seat and DuoFit® In-Wall 1.28 and 0.9 GPF Dual Auto Flush Tank System delivers unparalleled style and performance. The S550e WASHLET is fully automated, featuring 5 spray settings, auto open and close lid, heated seat, a nightlight, and instantaneous water heating. The WASHLET® S550e features TOTO's technologically advanced EWATER+® system that mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals. The self-cleaning wand also uses the advanced EWATER+ to automatically clean before and after every use. PREMIST® wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The TOTO WASHLET® S550e is operated by a luxury style illuminated touch button remote with 4-user memory storage to save preferred settings. The DuoFit® tank provides a WaterSense® certified dual-flush option with TOTO’s Dual-Max® flushing system. The AP bowl features TOTO’s DYNAMAX TORNADO FLUSH®, a hole-free rim design that generates a centrifugal, cyclonic rinsing action with the option of 0.9 or 1.28 gallons of water. Auto Open/ Close lid is coupled with optional Auto Flush kit to provide a hands-free experience with after every use. No need to touch buttons or handles, and never worry about someone forgetting to flush. This wall hung toilet bowl also features TOTO's CEFIONTECT® glaze that minimizes waste from sticking to the ceramic. CEFIONTECT®, EWATER+®, and DYNAMAX 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 DuoFit® harness allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals.
