Key Features & Innovations


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.

The surface layer that makes up the ionized barrier is more consistent and uniform and has a higher density on the CeFiONtect surface than on the conventional surface.


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

3-D Tornado Flush

The 3-D Tornado flushing system not only features three powerful nozzles that create a centrifugal, cyclonic rinsing action but also the option of choosing between 0.9 or 1.28 gallons per flush. This technologically-advanced high-efficiency system is remarkably effective, saving you up to 35% more water than the standard 1.6 GPF. The modern hole-free rim design also means that it performs more consistently and is easy to clean.
