The New Toto® Drake® Elongated Universal Height Toilet Bowl for 10 in Rough In with CEFIONTECT® is designed for use with a compatible Drake® toilet tank. When paired with compatible tank, the Drake® features Toto®'s DYNAMAX Tornado Flush® system that utilizes a 360 deg 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. The Universal Height design allows for a more comfortable seat position across a wide range of users. When paired with a certified compatible tank, the Drake® meets the standards for EPA WaterSense® and California's CEC and CALGreen requirements. This version of the Drake® bowl comes ready for install into a 10 in 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.
