When installing base cabinets, experts usually install the ___ cabinet first

• A. End
• B. Corner
• C. Center
• D. Back

Answer: (B)

Starting with the corner cabinet gives you a solid reference point for the entire cabinet run. The corner sits at the intersection of two walls, so when you plumb and level it and secure it, you’ve established the exact line and setback against both walls. This lets you position the adjacent cabinets so their faces line up consistently, keeps door and drawer fronts aligned, and makes it easy to shim and adjust as needed along the whole run. If you begin with an end cabinet, you’re anchoring only one wall and you lose a reliable two-wall reference, which can lead to misalignment later. The center cabinet isn’t a fixed anchor for layout, and a back cabinet isn’t a standard starting reference in base-cabinet runs. This is why the corner cabinet is the best first choice.
