How to Replace Kitchen Cabinet Doors and Hinges

Upgrading a tired kitchen does not always require ripping out sturdy carcass units. By replacing kitchen cabinet doors and updating the hardware, you can completely transform the aesthetic and functionality of your space at a fraction of the cost. Whether you are fitting brand-new replacement fronts or upgrading to modern soft-close mechanisms, achieving a professional finish relies on accurate measuring, correct hinge selection, and proper alignment.

Choosing the Correct Hinges and Mounting Plates

Before ordering new fronts or hardware, establish the type of cabinet construction you have. Most modern UK kitchens use frameless carcass units where standard European concealed hinges (often referred to as cup hinges) are standard practice.

• Full Overlay: The door sits directly over the front edge of the cabinet carcass, concealing the entire panel edge. This is the most common configuration in contemporary kitchens.
• Half Overlay: Two doors share a single central divider panel (typically 18 mm thick), each covering half of the carcass edge.
• Inset: The door sits entirely flush inside the carcass opening, exposing the cabinet frame edges.

Make sure to pair your chosen hinge with the correct mounting plate height (such as 0 mm or 2 mm) to match your carcass thickness, ensuring smooth operation and correct door reveal gaps.

Measuring and Drilling for Concealed Hinges

If your replacement doors do not come pre-drilled, you will need to drill the hinge cup holes yourself using a 35 mm Forstner bit. Accuracy is critical at this stage to ensure smooth movement and prevent binding.

1. Mark the Centres: Standard hinge positions are usually 100 mm to 120 mm from the top and bottom edges of the door. Measure and mark the vertical centre line, typically 21 mm to 22.5 mm in from the outer edge (depending on the required edge-to-cup distance, known as the 'tab' or 'k-distance').
2. Drill the Cup Holes: Use a drill press or a handheld drill fitted with a depth stop. Drill carefully to standard cup depth (typically 11.5 mm to 12.5 mm). Do not drill too deep, or you risk piercing the front face of the door.
3. Secure the Hinges: Place the hinge body into the hole, square the hinge arm using a straight edge against the door, and pilot-drill the fixing screw holes before driving in the screws.

Hanging and Aligning the Cabinet Doors

Mounting plates are secured inside the carcass, standardly 37 mm back from the front edge to the centre of the screw line, matching the standard 32 mm system spacing. Once the plates are fitted, clip-on or slide-on hinge arms make attaching the doors straightforward.

Once hung, use the three-way adjustment screws found on concealed hinges to achieve perfectly even gaps between doors:

• Lateral Adjustment (Side-to-Side): Adjusts the horizontal gap between adjacent doors and corrects tilt.
• Vertical Adjustment (Height): Loosen the mounting plate screws or use the cam adjustment on the plate to raise or lower the door.
• Depth Adjustment (In-and-Out): Moves the door closer to or further away from the carcass edge, ensuring the door sits flat against the cabinet buffer pads without catching.

Fitting Handles and Final Adjustments

When replacing kitchen cabinet doors, fitting new handles or knobs completes the transformation. Create a simple timber or cardboard drilling jig to ensure consistent handle placement across every door and drawer front. Always drill from the front face through to the back, clamping a scrap block of wood behind the exit hole to prevent the veneer or laminate from blowing out. Finally, fine-tune the soft-close tension mechanisms on your hinges for a quiet, uniform closing action throughout the kitchen.
