The Toto® RP™ Dual-Flush Elongated Wall Hung Toilet with high-efficiency flush with Cefiontect® opens up bathroom space, delivering style and innovative performance. The skirted design of the RP™ wall-hung bowl conceals the trap way, which enhances the elegant look of the toilet and adds a level of sophistication. Skirted design toilets also eliminate the need to reach behind the bowl to clean the nooks and crannies of the exterior trap way. The RP™ wall-hung bowl features Toto’s® 3D Tornado Flush®, a hole-free rim design featuring 3 powerful nozzles that generate a centrifugal, cyclonic rinsing action with the option of a WaterSense® certified 0.9 or 1.28 gallons of water. Choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The RP™ wall-hung bowl features Cefiontect®, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with the 3D Tornado Flush®, assists to reduce the frequency of toilet cleanings, minimizing the use of water, harsh chemicals, and time required for cleaning. The RP™ wall-hung bowl has been designed for the best results when used with the TOTO® DuoFit® WT172M in-wall tank system. Only compatible with the SS247R#01 toilet seat.
