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 or 1.6 gpf. The high-efficiency 1 gal flush setting reduces water use by more than 30% over 1.6 gal toilets, which adds up to potential water savings of more than 5000 gal per toilet, per year.
