How to build a kitchen base cabinet

Building a kitchen base cabinet

Our guide will show you how to install base cabinets. Starting from marking up the wall, you’ll find out where best to position your cabinets, how to account for piping and skirting boards, how to attach cabinets to one another, how to fit a side panel and cut it to size. Follow the steps outlined and you’ll have base units that not only provide essential storage but are sturdy and level enough to support your kitchen worktop.


If you have a timber frame wall, identify the secure fixing points before starting the installation process. Also check the walls for internal pipes and wires. If you need to factor in skirting boards or external pipes, bear this in mind from the outset. Make sure you have all necessary parts, too.


Use a cleaning product appropriate for the cabinet surface to avoid damaging the material. You should be able to find guidance for this in the manufacturer's instructions.

Wickes Tip

Beware of uneven flooring. If your flooring is uneven, you should adjust the legs of your cabinets until they are level before fully installing your cabinets. We have used spring loaded G-Clamps with non marking pads here. If you are using a cast iron clamp, it's a good idea to use offcuts of card on your cabinets to protect them from marks.


  • When using a circular saw or jigsaw, you should always use protective goggles, gloves and a face mask. Goggles and gloves should be used when drilling. Before drilling into walls and floors, always remember to check for pipes and wires using a cable and pipe detector.

Step by step instructions

step 1 of building a base cabinet

Take the side panels and place them on the floor as shown above with the holes facing up.

step 2 of building a base cabinet

On the outside edge of each panel, screw cam studs into the top and bottom holes. On the back edge, close to the groove, leave the corner holes empty and screw cam studs into the next hole at the top and bottom. These will connect the panels to the top struts and bottom panel using locking cams.

step 3 of building a base cabinet

For extra strength, place four dowels into each side panel. Two will go in the holes you left empty near the groove.The third will go in the top outside corner next to the cam stud. At the bottom outside corner, leave the hole next to the cam stud empty and place the fourth dowel in the next hole along.

step 4 of building a base cabinet

Place the locking cams into the large holes in the top struts and bottom panel.

step 5 of building a base cabinet

Make sure the arrows on the locking cams point toward the outside edge of the strut, this means they are unlocked and can receive the cam studs.

step 6 of building a base cabinet

Gently place the top struts onto one of the side panels, sliding them down onto the dowels and cam studs.

step 7 of building a base cabinet

Secure the cam locks by turning firmly clockwise using a screwdriver, being careful not to over tighten.

step 8 of building a base cabinet

Slot the bottom panel onto the same side panel as you've attached the top struts to and secure the cam studs.

step 9 of building a base cabinet

Carefully slot the second side panel onto the base panel and top struts and secure the cam locks.

step 10 of building a base cabinet

The back panel will slide in along the groove created by the base panel and side panels. Secure it to the back top strut using the three screws provided.

step 11 of building a base cabinet

Place the four leg sleeves onto the bottom of the base panel, making sure the small overhang on each supports the base of the side panels. Tap in the lugs and secure with the screws.

step 12 of building a base cabinet

Place the four legs into the sleeves. Turn the cabinet onto its legs, being careful not to put pressure on any of the legs at an angle, and twist the legs to adjust the height.
