The TOTO Promenade II 1.28 GPF Toilet Tank is designed for use with the Promenade II bowl. The Promenade II tank includes a tank to bowl gasket, tank to bowl hardware, and toilet bolt caps. The tank 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 tank comes equipped with a decorative left-hand chrome trip lever. The Promenade II meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: toilet bowl, wax ring, toilet mounting bolts, water supply lines, and toilet seat. The Promenade II ST403E tank can be used on the following bowls: C404CUFG and C404CUF.
