The Eco UltraMax® dual flush elongated two-piece toilet (Seat Included) projects Toto's mark of excellence: “people planet water.” the Toto eco UltraMax features a sleek, one-piece design that will immediately beautify the appearance of your bathroom. The one-piece design is not only aesthetically pleasing but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. The total eco UltraMax utilizes Toto's e-max® flushing system. The e-max flushing system features a 3” wide flush valve, extra-large siphon jet, and a large trapway. This reliable, highly efficient combination generates a powerful cleansing flush while only using 1.28 gallons of water. The Toto's Eco UltraMax 1.28 GPF meets the standards for EPA watersense®, and California's Eec and Walgreen requirements. The Toto's Eco Ultramax has a left-hand chrome trip lever and has an included Toto's softclose® seat, wax ring, and toilet mounting bolts.
