The TOTO Promenade II Universal Height Elongated Toilet Bowl is designed for use with the Promenade II 1G(R) ST403U 1.0GPF or Promenade II ST403E 1.28GPF tank. The Promenade II 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 TOTO Promenade II 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 is designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users. The bowl is ADA compliant and when paired with its tank, it 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: tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat.
