The Sterling Stinson 1.28-gallon gravity toilet is precision-engineered to use water effectively and efficiently. With ProForce technology, the Sterling HET delivers consistent, reliable flushing power and completely rinses the bowl clean. It also features a five-year one-flush cleansing performance warranty. Subtle design lines offer a clean appearance that suits a variety of commercial settings. The Stinson toilet base is sized to help cover the old footprint left by many standard two-piece toilets.
