The TOTO® RP™ Wall-Hung D-Shape Toilet and DuoFit® In-Wall 1.28 and 0.9 GPF Dual-Flush Tank System with Copper Supply opens up bathroom space, delivering style and innovative performance. The DuoFit® provides a WaterSense® certified dual-flush option with TOTO’s Dual-Max® flushing system. Choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. This package arrives complete with a rectangular dual flush push plate and D-shape SoftClose® seat. The skirted design of the RP bowl conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. Skirted design toilets also eliminate the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. The RP bowl features TOTO’s 3D TORNADO FLUSH®, a hole-free rim design featuring three powerful nozzles that generate a centrifugal, cyclonic rinsing action with the option of 0.9 or 1.28 gallons of water. This wall hung toilet bowl also features TOTO's CEFIONTECT® glaze that minimizes waste from sticking to the ceramic. This feature, coupled with the 3D TORNADO FLUSH®, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The DuoFit®harness allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals. The in-wall unit can support up to 880lbs when installed properly. The kit arrives ready to be installed within a 2” x 6” stud setting with a 2 x 6 polyethylene waste outlet. If you require installation within a 2” x 4” setting, you can purchase TOTO’s 2” x 4” PVC outlet kit (THU343).
