Ceramic is made of coarse clay that is hardened by heat. Standard ceramic tiles come in squares in a range of sizes. Squares often are a solid color or have a pattern that shows off hues of one color. Glazed ceramic is virtually slip-proof. Stark white subway tiles are a popular type of ceramic tile. Traditional 3-inch x 6-inch subway tiles are ideal for a backsplash.
Porcelain is a type of ceramic that is inherently waterproof. Made of fine kaolin clay, it is denser and harder than ceramic. Porcelain is the most durable tile material available. Tiles come in many colors and patterns, and some have a wood or stone look. Porcelain tile that imitates hardwood or marble, travertine, or other stone flooring
widens design opportunities.
