High profile elongated close coupled toilet with 12 in. rough-in. The low consumption G-Max flushing system (6 Lpf/1.6 Gpf) is preferred by innovative builders and discriminating homeowners. This quiet, powerful, commercial grade performance is driven by an extra-wide 3 in. flush valve and glazed 2-1/8 in. trap-way for effective, powerful flushes that prevent clogging. Elongated design provides for maximum comfort.
