The TOTO Connelly Universal Height Elongated Toilet Bowl is designed for use with the Connelly ST494M dual-flush tank. The skirted design of the bowl conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. Skirted design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. When paired with its tank, the Connelly features TOTO's 3D TORNADO FLUSH(R), a hole-free rim design featuring three powerful nozzles that generate a centrifugal, cyclonic rinsing action with the option of 0.9 or 1.28 gallons of water. This version of the Connelly includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with the 3D TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The Connelly bowl is designed to feature TOTO's Universal Height which allows for a more comfortable seat position across a wide range of users. When paired with its tank, the Connelly meets the standards for EPA WaterSense(R), and California's CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat.
