The TOTO T40 Connelly WASHLET+ Two-Piece Dual-Max, Dual Flush 1.28 and 0.9 GPF Universal Height Toilet combines contemporary design with innovations in style and water conservation. The Connelly has a concealed trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. 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. The left-hand chrome trip lever allows the user to decide the right flush for the appropriate job. Choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. 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(R) , assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The Connelly is designed to feature TOTO's Universal Height which allows for a more comfortable seat position across a wide range of users. This version of the Connelly offers TOTO T40 WASHLET+ compatibility for when you are ready to upgrade. WASHLET+ toilets feature a channel on the bowl surface to help conceal your WASHLET+ supply line and power cord for seamless integration.

The Connelly bowl and tank set includes a TOTO SoftClose(R) seat, tank to bowl gasket, tank to bowl hardware, and toilet bolt caps. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines.
