The clean and green rimless bowl design of the Cascade high-efficiency toilet (HET) reduces germs and bacteria that typically hide in difficult-to-access rim areas of the bowl, so they may get left behind during a routine cleaning. Available in either a round front bowl or elongated SmartHeight bowl design, the Cascade HET uses just 1.28 gallons per flush, saving 20 percent more water than older 1.6 GPF toilets. Thanks to its unique design, the Cascade is WaterSense-approved to meet EPA standards for water efficiency in the home. Toilets earning the WaterSense label have been certified to be at least 20 percent more efficient without sacrificing performance. With MagnaFlush high performance flushing technology and a three-inch flush valve for high-volume flow rate for a quick and quiet flush, the Cascade HET has a universal design that complements bathroom decor.
