TOTO Aquia IV two-piece elongated dual flush 1.28 and 0.8 GPF universal height toilet with CEFIONTECT is the epitome of modern form and function. The skirted design conceals the trap way, 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 trap way. TOTO Aquia IV two-piece features TOTO’s Dynamax Tornado Flush, utilizing a 360° 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 0.9 GPF rinse or 1.28 GPF for tougher jobs. This version of the Aquia IV offers TOTO T40 washlet and compatibility for when you are ready to upgrade. Washlet and toilets feature a channel on the bowl surface to help conceal your washlet and 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.
