How to Fit Replacement Drawer Fronts

August 25, 2026

Upgrading kitchen cabinets or bedroom furniture often begins with updating the facings. Installing replacement drawer fronts onto existing drawer boxes is one of the most cost-effective ways to transform tired cabinetry without tearing out functional carcasses. However, achieving clean reveals, consistent gaps, and smooth operation requires careful measurement and the right hardware.

Preparation and Accurate Measuring

Before ordering or fitting your fronts, you must determine whether your cabinets use standard overlay, full overlay, or inset drawer fronts. For standard overlay units, measure the height and width of your existing fronts down to the millimetre. Do not simply measure the internal drawer box, as the front is typically significantly larger to conceal the carcass edges.

When planning your layout, maintain standard expansion gaps:

Vertical gaps: Allow a 3 mm to 4 mm gap between adjacent stacked drawer fronts.
Horizontal reveals: Ensure uniform spacing (typically 2 mm to 3 mm) between the drawer front and the carcass side or adjoining door.
Bottom clearance: Ensure the lowest drawer front clears the cabinet plinth or floor without rubbing.

Essential Hardware for Drawer Fronts Replacement

A successful drawer fronts replacement project relies on dependable fixings. The method you use to mount the panel depends on the construction of your drawer boxes:

Drawer front fixing brackets: For modern metal-sided drawer boxes (such as soft-close double-wall systems), specialised clip-in brackets screw directly into the rear face of the new panel and click into the metal drawer sides.
Sub-front screws: For traditional five-piece wooden or MDF drawer boxes, the new front is secured directly through the pre-existing front timber panel from the inside.
Handles and knobs: Choose handles with fixing screws sized appropriately for the combined thickness of your drawer front and internal box.
Adjustable drawer runners: Using runners with built-in 2D or 3D cam adjustments allows you to fine-tune horizontal, vertical, and depth alignment after the front is mounted.

Step-by-Step Installation Guide

Follow these steps to mount and align your new panels precisely:

1. Strip the Existing Boxes

Remove the drawers from the cabinet carcass. Detach the old handles and unscrew or unclip the old fronts. If using wooden boxes, inspect the sub-front for old screw holes. If these holes overlap awkwardly with new fixing points, plug them with wooden dowels and PVA glue, then sand flush.

2. Position and Temporarily Secure

Reinsert the drawer boxes into the carcass. Place your lowest replacement drawer front in position using plastic shims or 3 mm spacers beneath it to set the base reveal. Use strong double-sided tape or specialised drawer front alignment clamps to hold the front temporarily against the drawer box. Check for level and ensure horizontal reveals match surrounding doors.

3. Fix Permanently

Carefully pull the drawer open while holding the clamped front in place. Drill pilot holes from inside the drawer box through the sub-front into the back of the new drawer panel. Use a drill stop collar to avoid drilling completely through the finished decorative face. Drive wood screws (typically 25 mm to 30 mm, depending on combined timber thickness) through the internal face to lock the front securely.

Fine-Tuning Alignment and Fitting Handles

Once all fronts are mounted, step back to check the visual lines. If any front is slightly out of square, use the adjustment cams on your drawer runners to raise, lower, or tilt the drawer box until all reveal gaps are completely parallel. Finish by measuring the exact centre of your new front, drilling through both the front and sub-box, and bolting on your replacement handles.
