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 S7A WASHLET is fully automated, featuring 5 spray settings, auto open and close lid, heated seat, a nightlight, and instantaneous water heating. The WASHLET S7A 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 S7A 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.
