The TOTO(R) Drake(R) Round TORNADO FLUSH(R) Toilet Bowl is designed for use with compatible Drake tanks. The Drake features TOTO's TORNADO FLUSH(R), a rimless, hole-free design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This Drake bowl 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 the correct tank, can meet the standards for EPA WaterSense(R), and California's CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: compatible Drake tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat.
