Gerber’s newest dual-flush addition to its Logan Square collection is a high-efficiency two-piece toilet that features two buttons on the top of the tank to dictate the flush rate – one at 1.1 gpf for liquids and the other at 1.6 gpf for solids. It also features an elongated rim for comfort and a fully glazed trapway. It is WaterSense certified and available in white and biscuit. In addition to the standard model, Gerber offers an ADA-compliant ErgoHeight bowl. Both options are installed with a 12” rough-in.
