The TOTO® Drake® Round TORNADO FLUSH® Toilet Bowl is designed for use with compatible Drake tanks. The Drake features TOTO’s TORNADO FLUSH®, 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®, 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.
