The TOTO Drake® elongated Tornado flush® toilet bowl, washlet®+ ready is designed for a T40 washlet+ connection and features a channel on the bowl surface to run your washlet supply line and power cord for the purpose of concealing them. The Drake® features TOTO’s Tornado flush, a rimless, hole-free design with dual nozzles that create a centrifugal washing action that assists in rinsing the bowl more efficiently. The washlet+ TOTO Drake® includes cefiontect, a layer of exceptionally smooth glaze that minimizes waste from sticking to the ceramic. Cefiontect, coupled with Tornado flush®, assists in reducing the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. This version of the Drake® offers TOTO T40 washlet+ compatibility for when you are ready to upgrade. When paired with the correct tank, the toilet 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 tank, wax ring, toilet mounting bolts, water supply lines, and TOTO toilet seat or T40 washlet+ electronic bidet seat.
