The TOTO Drake II Universal Height Round Toilet Bowl is designed for use with the Drake II 1G ST453U 1.0GPF or Drake II ST454E 1.28GPF tank. The Drake 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 Drake 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.
