The VOLCANO shape featured in the section connecting the tank with the toilet makes it easy to clean. The toilet is made with INAX's proprietary AQUA CERAMIC technology, which prevents the attachment of waste and the build-up of black watermarks. As the toilet bowl is rimless, it will only require a quick sweep inside the bowl to keep the toilet shiny, liberating you from the burden of daily toilet cleaning.
