Commonly found in restaurants, metal countertops are experiencing a renewed popularity in residential kitchens. Metal countertops are nonporous and, as a whole, are resistant to heat, susceptible to scratching, and have excellent hygienic properties. Depending on the material (stainless steel, copper, zinc, and nickel), options selected (backsplash, how the sink is mounted, etc.), and size, metal countertops may cost anywhere between $75 and $200 a square foot.
