Ceramic tile floors offer a very attractive and durable alternative to other floor finishes. They come in many different sizes and colors to match the décor of any room and they can provide years of maintenance-free use. Additionally, ceramic tiles are fairly easy to install. Ceramic tiles have one major prerequisite – you must have a smooth and rigid sub-floor to support the installation. Ceramic tiles are not flexible in the least, so they can crack if installed over a rough surface or thin sub-floor. Consider putting down ½-inch plywood to provide a better surface for the installation.
