A toilet bowl is most often made of a ceramic, but can sometimes be made of stainless steel or composite plastics . Toilet bowls are mounted in any one of three basic manners: above - floor mounted (pedestal), wall mounted (cantilever), or in - floor mounted (squat toilet). </P> <P> Within the bowl, there are three main waterway design systems: the siphoning trapped system (found primarily in North American residential installations, and in North American light commercial installations), the non-siphoning trapped system (found in most other installations both inside and outside of North America), and the valve - closet system (found in many specialty applications, such as in trains, planes, buses, and other such installations around the world). Older style toilets called "washout" toilets are now only found in a few locations . </P>
