This completely new surface material for sanitary ware was developed to solve the problem of cleanability, the greatest problem users have with toilets. The super-hydrophilic ceramic surface allows water to penetrate under and lift stains, so fixtures stay clean for 100 years by the power of normal washing with water. We have always worked to enhance the cleanability of toilets, but AQUA CERAMIC is the ultimate invention for totally eliminating the trouble of cleaning. This next-generation anti-stain technology contributes to clean and comfortable residential living.
