The TOTO Promenade II Universal Height Elongated Toilet Bowl is designed for use with the Promenade II 1G® ST403U 1.0gpf or Promenade II ST403E 1.28gpf tank. The Promenade 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. 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®, 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.
