The company’s WaterSense-certified Saile toilet is a seamless, one-piece, dual-flush unit designed to eliminate liquid or bulk waste with a single flush. The two-button actuator lets users choose 1.6 or 0.8 gpf. A family of four can save, on average, up to 8,000 gallons of water each year with the 0.8-gallon flush (versus 3.5-gpf models), according to the company. The toilet seat features an over-molded lid that covers the seat ring for a finished look. The device has a skirted toilet and is designed for flush-to-wall installation. 800.456.4537. www.kohler.com.
