The TOTO Supreme II One-Piece Elongated 1.28 GPF Universal Height Toilet has a clean low-profile design and projects TOTO?s mark of excellence: ?People Planet Water.? The TOTO Supreme II 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 Supreme II features TOTO?s Tornado Flush?, a hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. The TOTO Supreme II is designed in TOTO?s Universal Height, which allows for a more comfortable seat position across a wide range of users.
