A typical stock kitchen from Merillat will take about eight days for GBC to deliver to your home. Semi-custom cabinets take four to six weeks. Custom cabinets take between eight and 12 weeks to deliver. If GBC performs the installation, you should plan on one to two weeks after delivery to complete the project. The type of countertop selected will also impact the project completion time. Laminate tops take about a week, and granite takes up to four weeks.
