How to install a 300mm base cabinet

Overview

Flat pack kitchen cabinets are an affordable way to renovate a kitchen. We'll teach you how to put together a 300mm base cabinet yourself. You'll see how to screw the panels together and install the plastic feet on the base.

Steps

1Attach the sides of the 300mm base cabinet to the base panel

Put the first side panel into place and line up the pre-drilled holes. Use an impact driver to gently drive the screws into place. When the first side is on, turn the cabinet over and do the same on the other side. 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.

2Attach the back to the 300mm base cabinet

Put the back panel into place and line up the pre-drilled holes. Screw the back and both side panels together, then turn the cabinet upside down and do the base panel. Once again, check your edges are properly lined up and use the rubber mallet to tap them into place before you give your screws a final tighten.

3Attach the top rail to the 300mm base cabinet

Put the top rail into position. Push all four screws into place 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.

4Attach 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 pre-drilled 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.

5Adjust 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.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
