The New TOTO Drake Elongated Toilet Bowl with CEFIONTECT is designed for use with a compatible Drake toilet tank. When paired with its compatible tank, the Drake bowl features TOTO’s DYNAMAX TORNADO FLUSH system that utilizes 360 degree cleaning power to reach every part of the bowl. The enhanced design of the new Drake inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. This version of the Drake bowl includes CEFIONTECT, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature paired with the powerful DYNAMAX TORNADO FLUSH system, helps reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. When paired with a certified compatible tank, the Drake meets the standards for EPA WaterSense, and California’s CEC and CALGreen requirements. The Drake comes ready for install into a 12 inch rough-in. Additional items needed for installation and use must be purchased separately: Compatible Drake dual flush tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat.
