The TOTO Supreme II 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. This version of the Supreme II offers TOTO T40 WASHLET® compatibility for when you are ready to upgrade. WASHLET® toilets feature a channel on the bowl surface to help conceal your WASHLET® supply line and power cord for seamless integration. 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 includes a tank to bowl gasket, tank to bowl hardware, toilet bolt caps and SoftClose toilet seat. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, water supply lines, and optional T40 WASHLET electronic bidet seat.
