Countertop styles refer to the various types of materials and designs used to make kitchen or bathroom countertops. Some popular countertop styles include granite, marble, quartz, laminate, solid surface, and concrete. Each style has its own unique look, durability, and maintenance requirements. Granite and marble are natural stones that offer a luxurious and timeless appearance, while quartz and solid surface materials are man-made and offer a wider range of color options. Laminate is an affordable option that comes in a variety of colors and patterns, and concrete countertops offer a modern and industrial look.
