The TOTO Eco Guinevere Elongated 1.28 GPF Universal Height Skirted Toilet with CEFIONTECT has classic, decorative look and projects TOTO''''s mark of excellence: ''''People Planet Water.'''' TOTO Eco Guinevere 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 Skirted Design of the TOTO Eco Guinevere conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. Skirted Design toilets also eliminate the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. The TOTO Eco Guinevere 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 Eco Guinevere includes CEFIONTECT, a layer of exceptionally smooth glaze that minimizes waste from sticking 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 Eco Guinevere is designed in TOTO''''s Universal Height, which allows for a more comfortable seat position across a wide range of users. The Eco Guinevere is ADA compliant and meets the standards for EPA WaterSense, and California''''s CEC and CALGreen requirements. The TOTO Eco Guinevere has a left-hand chrome trip lever; TOTO SoftClose or WASHLET Electric Bidet seats are purchased separately.
