The unique combination of clean lines and square edges makes the Allerton™ Suite of products an understated, elegant style choice. The two-piece high efficiency toilet is WaterSense approved and operates at a conservative 1.28 gpf (4.8 Lpf) without sacrificing performance. Its reliability and performance also stems from its top-of-the-line components - 3" flush valve, fully glazed trapway and dual siphon set to name a few. This model features an elongated bowl for additional comfort.
