The TOTO Eco UltraMax features a sleek, one-piece design that will immediately beautify the appearance of your bathroom. The one-piece design 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 TOTO Eco UltraMax utilizes TOTO's E-Max(R) 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 Eco UltraMax 1.28 GPF meets the standards for EPA WaterSense(R), and California's CEC and CALGreen requirements. The TOTO Eco UltraMax has a left-hand chrome trip lever and has an included TOTO SoftClose(R) seat.
