A classic, high-performance design for modern commercial restrooms, Zurn’s high-efficiency toilets are a perfect blend of form and function. With chloramine-resistant valve components and a high-gloss vitreous china finish, it’s stain-resistant, sanitary, and durable inside and out. The Z5535-K is a standard height, elongated rim toilet bowl. It has an extra-large base that covers gaps, unfinished, or non-matching flooring, simplifying retrofit installation. It features our EcoVantage® high-performance siphon-jet, a high-efficiency 1.28 gpf, and a 3-inch flush valve which combine to provide powerful, yet economical flushing action. Add an oblong toilet seat (Z5958SS-EL), bolt and wax ring (Z5972-COMB), and standard stop with riser (Z8800-CR) for a complete setup. Zurn two-piece toilets offer a simple, durable solution for new or retrofit commercial bathroom projects.
