Toto. The Eco Soiree high-efficiency toilet looks like a traditional two-piece product, but actually has a one-piece design. The glazed ceramic unit flushes with 1.28 gallons of water, making it eligible for the EPA’s WaterSense certification. It features a Double Cyclone flush engine, 12-inch rough-in, elongated bowl with SoftClose seat, and chrome lever handle. –Nigel F. Maynard
