How to build kitchen base cabinets

Overview

The base cabinet is the standard storage unit of any flat pack kitchen. We show you how to screw all the panels together yourself. You will also see how to attach the feet and adjust the height of your cabinets to keep them level on an uneven floor.

    Steps

    1

    Attach the back of the kitchen cabinet to the base panel

    Put the back and base panels together so the pre-drilled screw holes line up. Use an impact driver to gently drive the screws into place. Check to see if the joining edges have properly lined up. If not, tap them lightly into place with a rubber mallet and then tighten the screws.

    Attach the sides to the kitchen cabinet

    Put the first side panel into place and line up the pre-drilled holes. Screw the base and side panels together, then do the back panel. When the first side is on, turn the cabinet over and do the same on the other side. Remember to use the rubber mallet to keep your edges lined up.

    Attach the top rail to the kitchen cabinet

    Put the top rail into position. Push all four screws into position with your thumb to temporarily hold the rail in place. Then drive the screws in and use the rubber mallet again to tap the edges into place before giving the screws a final tighten.

    Attach the plastic feet to the bottom of the kitchen cabinet

    The plastic feet for your kitchen cabinets come in four parts – base plate, tube, screw thread and foot. Attach the base plate to the base of the cabinet, using the predrilled holes and the short screws. Push the tubes into the base plates and the feet onto the screw threads. Then drive the screw threads into the tubes and you're done

    Adjust the height of the feet

    You can adjust the height of your feet by screwing the threads in or out. This is very useful if your floor isn't level. Use a combination square to help set the height of all the feet at 145mm. Then put the cabinet in place and adjust the feet if you need to level it up on an uneven floor.

    Install the shelf in the kitchen cabinet

    The sides of the cabinet have pre-drilled holes to hold shelf support brackets. Select the height you want for your shelf and push your brackets into the holes at that level. To ensure you put the brackets for each shelf on the same level, it's a good idea to count the number of holes between brackets. Finish by placing the shelf on top of the brackets.
