Prosa White Elongated Chair height 12-in Rough-In WaterSense 1.28 GPF Soft Close 1-piece Toilet. One-piece toilets integrate the tank and bowl into a seamless, easy-to-clean design. Elongated bowl offers added room and comfort. Comfort Height® feature offers chair-height seating that makes sitting down and standing up easier for most adults. Quiet-Close™ lid and seat prevents slamming. Left-hand Polished Chrome trip lever. 2-1/8" (54 mm) fully glazed trapway. AquaPiston® canister optimizes the flow out of the tank, harnessing gravity and the natural powerful reducing cascade of water to increase the power and effectiveness of the flush. Easy-to-flush canister design requires less force to actuate than a 3" (76 mm) flapper, and has 90% less exposed seal material which resists conditions that cause wear, tear, shrinkage and swelling. Precision-engineered patented tank, bowl, and trapway create strong siphon during flushing
