The Canto includes all ICERA’s signature plumbing technology, including the EcoQuattro flushing system that combines flushing power, exceptional cleanliness and minimal water usage. As a high-efficiency toilet consuming only 1.28 gallons per flush, the Canto features an oversized 2 1⁄8” trapway and 3” flush valve to virtually eliminate clogging. A MicroGlaze anti-microbial finish is stain resistant and makes for an easy-to-clean bowl. Crafted of vitreous china, the Canto includes several desirable touches, such as a soft-close and quick-release seat and an ADA-compliant chair-height elongated bowl. All ICERA toilets are 100% factory flush tested and come with a limited lifetime warranty. ICERA.
