The TOTO Promenade II one-piece elongated 1.28 GPF universal height toilet with cefiontect projects toto?s mark of excellence: ?people planet water.? the TOTO Promenade 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 Promenade 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. This version of the TOTO Promenade II includes cefiontect, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with tornado flush, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The TOTO Promenade II is designed in toto?s universal height, which allows for a more comfortable seat position across a wide range of users. The Promenade II is ADA Compliant and meets the standards for epa WaterSense, and california?s CEC and calgreen requirements. The TOTO Promenade II has a left-hand chrome trip lever and an included TOTO SoftClose seat.
