The Persuade collection captures the essence of modernity in subtle curves and clean lines. With its sleek symmetry and compact design, this Persuade Curv toilet tank adds style to the bathroom without sacrificing comfort or water savings. The tank flushes with the press of a button, offering the choice of 1.0 or 1.6 gallons per flush. The high-efficiency 1.0-gallon flush setting reduces water use by more than 30 percent over 1.6-gallon toilets, which adds up to potential water savings of more than 5,000 gallons per toilet, per year. Top-mount two-button flush offers a choice of 1.0 or 1.6 gallons per flush (gpf). Combines with the K-4326 bowl to create a complete K-6355 Persuade toilet. Coordinates with other products in the Persuade collection.
