It could take up to 2 days. The install will take anywhere from 1-3 hrs depending on how big or small, if it has seams or backsplashes, waterfalls if the cabinets are not aligned and we need to shim the countertops and level them. Typically if there is a backsplash that needs to go under the mirror we will have to measure it after the countertops are installed and the top has cured for at least a day.
