The TOTO Ultimate One-Piece Round Bowl 1.6 GPF Toilet projects TOTO's mark of excellence: "People Planet Water." The TOTO Ultimate 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 TOTO Ultimate features TOTO's innovative Power Gravity flushing system that enables the toilet to perform powerful flushes. The TOTO Ultimate includes a TOTO SoftClose(R) seat and a left-hand side chrome lever.
