The TOTO Supreme II WASHLET® One-Piece Elongated 1.28 GPF Universal Height Toilet with CEFIONTECT features a sleek, one-piece design that will immediately enchance your bathroom. Supreme 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 TOTO Supreme II includes CEFIONTECT, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with TORNADO FLUSH®, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. TOTO Supreme II is designed for a T40 WASHLET connection and features a channel on the bowl surface to run your WASHLET supply line and power cord for the purpose of concealing them. The TOTO Supreme II is designed in TOTO’s Universal Height, which allows for a more comfortable seat position across a wide range of users. The Supreme II is ADA compliant and meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. The TOTO Supreme II 1G has a left-hand chrome trip lever. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, water supply lines, compatible SoftClose seat or TOTO T40 WASHLET electronic bidet seat.
