The TOTO Promenade II 1G Two-Piece Elongated 1.0 GPF Universal Height Toilet with CEFIONTECT is a beautifully designed decorative toilet. The Promenade II 1G bowl and tank set includes a tank to bowl gasket, tank to bowl hardware, and toilet bolt caps. The Promenade II 1G features TOTO's industry leading 1G technology, offering a powerful flush that flushes completely and fully with only one gallon of water. The Promenade II 1G features TOTO's TORNADO FLUSH(R), 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 Promenade II 1G includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. 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 Promenade II 1G is designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users. This version of the Promenade II 1G has a decorative left-hand chrome trip lever. The Promenade II 1G is ADA compliant and meets the standards for EPA WaterSense(R), and California's CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, water supply lines, and toilet seat.
