Some of the most common materials on kitchen countertops include natural stone such as marble and granite, stainless steel, concrete, engineered stone and corian. If it suits the design and space, often one or more of these options can be combined. It's important to decide which countertops will fit your lifestyle and how you will utilize the kitchen. Some of the key determining factors include appearance, maintenance and durability. If you cook a lot, corian is very easy to maintain while calacatta marble is elegant but requires care when cooking and entertaining as it is porous and can be easily stained.
