The Aquia IV 1G Two-Piece Elongated Dual Flush 1.0 and 0.8 GPF Toilet with CeFiONtect is the epitome of modern form and function. The skirted design 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. The Aquia IV features TOTO's DYNAMAX TORNADO FLUSH, utilizing a 360-degree cleaning power to reach every part of the bowl.

This version of the Aquia IV includes CeFiONtect, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with DYNAMAX TORNADO FLUSH, helps to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The chrome center-mounted push button that sits atop the tank allows you to proactively conserve water by choosing between a 0.8 GPF rinse or 1.0 GPF for tougher jobs.

The Aquia IV 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 Universal Height design allows for a more comfortable seat position across a wide range of users. The TOTO Aquia IV meets the standards for EPA WaterSense, and California's CEC and CALGreen requirements.

Comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. The Aquia IV bowl and tank set includes a SoftClose seat, tank to bowl hardware, a tank to bowl gasket, outlet socket, and toilet bolt caps. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines.
