Product Information


The TOTO T20 WASHLET+ Kit UltraMax II One-Piece Elongated 1.28 GPF Toilet and WASHLET S350e Bidet Seat is designed to conceal the WASHLET's power cord and water supply hose for a seamless installation. The WASHLET S350e 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 with water before each use, preventing waste buildup and keeping the toilet bowl clean. The WASHLET S350e is fully automated, including an illuminated remote control with 5 spray settings, auto open and close lid, heated seat, and instantaneous water heating. The UltraMax II 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 UltraMax II 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, minimizing the usage of water, harsh chemicals, and time required for cleaning. The UltraMax II is designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users. This WASHLET+ Kit includes the WASHLET with water supply adapter and UltraMax II toilet with seat and bolt caps. Compatible with T20 WASHLET+ electronic bidet seat and toilet bowl components only. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines.
