Prison-toilet combination units provide a single fixture where people can relieve themselves and wash up within their cells. Sometimes called prison comby units, they house a toilet and sink or a toilet, sink, and drinking fountain (bubbler) within one compact, vandal-resistant fixture. They're made of stainless steel or other heavy-gauge materials, so they won't crack or shatter like porcelain toilets.

Prison toilets are specialized toilets that resist damage and withstand frequent use in prisons, detention centers, and other rough-use environments. Also called jail toilets, prison toilets are made of stainless steel or other heavy-gauge materials, so they won't crack or shatter like porcelain toilets. Their seamless construction eliminates gaps or holes that could be used to hide contraband. They're typically installed in prison cells and correctional-facility bathrooms.
