The TOTO Drake II Universal Height Elongated Toilet Bowl is designed for use with the Drake II 1G ST453U 1.0gpf or Drake II ST454E 1.28gpf tank. The Drake II features TOTO's Tornado Flush, a hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the TOTO Drake II includes CeFiONtect, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with Tornado Flush, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The Drake II 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 its tank, it meets the standards for EPA WaterSense, and California's CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat.Features and Benefits Elongated front toilet bowl for use with Drake II ST454U or ST454E tank Tornado Flush system with a powerful centrifugal rinse CeFiONtect glaze gives the bowl a lubricious quality that prevents particles from adhering Universal height for more comfort across a broader range of individuals 12" rough-in Glazed trapway Purchased separately: tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat Specification SheetWarranty Document
