How to assemble a three drawer cabinet

Overview

The flat pack system makes it easy to design and build a kitchen yourself. We'll show you how to put a cabinet and drawers together. We'll also show you how to adjust the height of the cabinet to cope with uneven floors and walls.

Steps

1Attach the back of the drawer cabinet to the base

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.

2Attach the sides to the drawer 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.

3Attach 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. Once again, use the rubber mallet 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 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.

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.

6Assemble the drawers

All the drawers are put together in the same way. Screw the back and bottom panels together, then attach the front and sides. The sides are marked ‘left' and ‘right' and include pre-drilled holes for the drawer sliders. Once the drawers are assembled, you will need to attach runners and front panels. Check out our videos on how to install drawer runners and how to install drawer panels to find out what to do.

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.
