Replacing Kitchen Cabinet Fronts: Hardware & Fitting Guide

August 25, 2026

Updating tired kitchen units does not always require ripping out the entire carcass. Opting for replacement kitchen cabinet fronts is one of the most cost-effective ways to completely transform a kitchen space while preserving the structural layout. However, achieving a seamless, professional finish relies entirely on selecting and installing the correct hardware. From hinge cup placements to drawer runner alignments, getting the mechanical details right ensures your new doors hang straight and operate smoothly for years to come.

Measuring and Drilling Hinge Cup Positions

When planning a kitchen cabinet fronts replacement project, accurately mapping hinge locations is the most critical step. Most standard UK kitchen units utilise 35 mm concealed hinges (often referred to as Euro-style cup hinges), but the drilling pattern can vary significantly between manufacturers.

Cup Diameter and Depth: The standard hole diameter is 35 mm, with a typical boring depth between 11.5 mm and 13 mm. Ensure you do not drill through the face of the new door.
Boring Distance (K-Distance): This is the distance from the edge of the door to the edge of the 35 mm hole, usually between 3 mm and 6 mm. This offset determines how much the door overlaps the cabinet side.
Hole Centres: Measure the distance from the top and bottom edges of your existing doors to the centre of the hinge holes (commonly 100 mm or 120 mm from the edge). Transfer these measurements precisely to the new fronts.

Selecting the Correct Concealed Hinges and Plates

Concealed hinges are categorised by how the door sits relative to the carcass edge. Identifying your cabinet style ensures you buy the correct fitting:

Full Overlay: The door completely covers the front edge of the carcass wall, with a tiny gap between adjacent units. This is the most common setup in modern UK kitchens.
Half Overlay: Often used on central dividing panels where two doors share a single 18 mm carcass wall, each covering half of the edge.
Inset: The door sits entirely flush inside the carcass opening, exposing the front edges of the unit frame.

Pairing your hinges with the right mounting plates is equally important. Height-adjustable, clip-on mounting plates make fitting and fine-tuning significantly simpler than traditional slide-on plates. Look for integrated soft-close mechanisms within the hinge arm or cup to prevent doors from slamming shut.

Upgrading Drawer Runners and Internal Fittings

A kitchen cabinet front replacement often involves refreshing the drawer boxes alongside the doors. Modernising the internal running gear alongside the drawer fascias will dramatically improve everyday usability.

If you are attaching new drawer fronts to existing wooden or metal drawer boxes, check whether your runners need upgrading. Full-extension soft-close ball bearing runners allow complete access to the back of the drawer, while push-to-open runners eliminate the need for handles entirely, creating a clean, handleless aesthetic. Ensure front-fixing brackets are aligned precisely so the drawer faces sit parallel with neighbouring doors.

Fitting Handles, Knobs, and Catches

The hardware you choose to open your doors and drawers will define the finished look of the kitchen. Installing new handles requires careful marking to ensure absolute uniformity across all units.

Template Use: Use a rigid drilling jig or make a bespoke wooden template to mark fixings consistently on every door and drawer front.
Drilling Technique: Place a scrap piece of timber tightly behind the door where the drill bit will exit. This prevents breakout and splintering on the back face of the front.
Handleless Push Catches: For a modern minimalist finish, skip handles altogether and install mechanical or magnetic push-to-open latches onto the carcass interior.

Fine-Tuning Door Alignment

Once the replacement kitchen cabinet fronts are hung, minor misalignments are normal. Concealed hinges offer three-way adjustment via integrated screws on the hinge arm and mounting plate:

Lateral Adjustment (Side-to-Side): Adjusts the horizontal gap between adjacent doors.
Vertical Adjustment (Height): Moves the door up or down to align the top and bottom edges across the run of cabinets.
Depth Adjustment (In-and-Out): Sets the distance between the back of the door and the front of the carcass to prevent binding against the frame.
