The TOTO Drake Elongated Universal Height TORNADO FLUSH Toilet Bowl with 10 Inch Rough-In and CEFIONTECT 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 version of the TOTO Drake includes CEFIONTECT, a layer of exceptionally smooth glaze that minimizes waste from sticking to the ceramic. CEFIONTECT, coupled with TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. 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.
