The TOTO Connect+ Kit Vespin II 1G Two-Piece Elongated 1.0 GPF Toilet and Washlet S300e Bidet Seat is designed to conceal the Washlet's power cord and water supply hose for a seamless installation. The Washlet S300e 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 S300e is fully automated, including an illuminated remote control with 5 spray settings, heated seat, and instantaneous water heating. The skirted design of the Vespin II 1G conceals the trapway and adds an additional level of sophistication. The Vespin II 1G features TOTO?s industry leading 1G technology, offering a powerful flush with one gallon of water. The Vespin II 1G features TOTO?s Tornado Flush?, a hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the Vespin II 1G includes CeFiONtect?, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with the Washlet Premist and Tornado Flush, assists to reduce the frequency of toilet cleanings. The Vespin II 1G is designed in TOTO?s Universal Height, which allows for a more comfortable seat position across a wide range of users. This Connect+ Kit includes the Washlet, Vespin II toilet with hardware, and unifit outlet for 12" rough-in.
