The most durable kitchen countertop material depends on various factors, such as maintenance, cost, and usage. However, granite, quartz, and concrete are considered some of the most durable materials. Granite is a natural stone and is highly durable, but it requires periodic sealing to maintain its luster. Quartz countertops are made of engineered stone and are highly resistant to scratches and stains. Concrete countertops are also highly durable and can last years, but they require proper maintenance to prevent cracks and stains.
