The lifespan of a kitchen countertop depends on the material and maintenance. Natural stone countertops like granite and marble can typically last 20-25 years or even longer with proper care. Like quartz, engineered stone can last up to 15 years or more. Laminate countertops have a lifespan of 10-20 years, while solid surface countertops last for around 20 years. Wood countertops have a lifespan of 10-20 years, depending on the type of wood and maintenance.
