During your countertop estimate, our experts will provide you with a timeline based on your specific room dimensions, the customization required, and the material that you purchase. Since quartz countertops are factory-made and can require less time for installation than other materials, one to two days is a reasonable estimate. Granite countertops are heavier by nature and require more labor-intensive installation, so this process is likely to take two days and possibly three days for larger spaces. Marble countertops also require careful handling due to their weight to avoid damage, so anywhere from one to three days based on size and complexity is a normal timeframe.
