About TOTO CST646CEMFGT40#01 Aquia IV One-Piece Elongated Toilet with 1.28 GPF & 0.8 GPF Dual Flush with CeFiONtect

The Aquia IV One-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 trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. 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 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 technology, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic.

Key Features & Innovations

Dynamax Tornado Flush

Dynamax Tornado Flush combines powerful bowl cleaning and waste evacuation using water that is 100% projected from the rim creating 360° cleaning power. Using only 1.0/0.8 or 1.28/0.8 gallons per flush, coupled with a 25% larger trapway diameter, this high-efficiency system uses 20% less water with improved performance while also creating a quieter flush. With a modern rimless design, it performs more consistently and is easy to clean.

CeFiONtect

TOTO’s extraordinarily smooth CeFiONtect glaze prevents particulates from adhering to porous, ceramic surfaces. The ion-barrier in CeFiONtect keeps everything cleaner, longer. Less cleaning means fewer chemicals in the environment and less water used for cleaning.

Sectional View of Barrier Density By EPMA: The surface layer that makes up the ionized barrier, seen in red is more consistent and uniform and has a higher density on the CeFiONtect surface than on the conventional surface.

Surface View of AFM: Creating more smoothness helps minimize debris from sticking. With nothing to cling to particles can be washed away with every flash.
