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.



We take pride in the fact that our toilets are not only beautiful to look at, they have inner beauty as well. It's there in our high-performance flushing systems, our specially designed trapway.

ADA Compliant

The American Disability Act (ADA) was enacted in 1990 to establish design codes to serve people of all ages and abilities. A core principle behind TOTO Total Design, ADA standards consider the needs of everyone, no matter their needs, without additional adaptation or specialization, optimizing the bathroom experience for all generations in the family home.

Universal Height

Central to TOTO Total Design is taking into account people of all ages and abilities. Universal Height offers sinks and toilets at a more manageable height, making the bathroom more accessible and enjoyable for everyone. This simple design principle allows all people, from the beginning of their days through the rest of their lives, to completely enjoy their bathroom experience, regardless of age or ability.
