Project Overview

Anyone can have a go at installing a cut-to-measure benchtop. All it takes is some basic tools and know-how to measure and connect the panels. This video takes you all through the steps involved in assembling a benchtop, which are also detailed in your instruction guide.

Step by Step Instructions

1 Assemble the waterfall edge panel
2 Secure the waterfall edge to the cabinet
3 Line up the benchtops
4 Insert the bench connectors
5 Secure benchtops into place
6 Connect the benchtop to the back panel
  • Step 1. Assemble the waterfall edge panel

    Remove the top and second drawers from your cabinet so you can screw in the waterfall edge from the inside. Place the waterfall panel alongside the cabinet, leaving the edge slightly overhanging the length of the cabinet. We have selected a distance of 40mm proud for this, with 20mm to account for drawer fronts and the remaining 20mm purely for aesthetics. 

  • Step 2. Secure the waterfall edge to the cabinet

    Once you have set your waterfall edge measurements, clamp the panel into place. Pre-drill your holes into two points at the front and two points at the back. Now screw it in place. In our case, the waterfall panel has a large overhang at the back that will be used for a breakfast bar. Remove the clamp and have someone help you carry and place the long benchtop on top of the cabinet. 

  • Step 3. Line up the benchtops

    On the underside of each benchtop are grooves for the bench connectors. To bring the two benchtops together, these connectors are slotted into the allocated grooves and tightened with a spanner until secure. Do not secure the benchtop in its final place yet, as it will be easier to install the short benchtop while this is still slightly movable.

  • Step 4. Insert the bench connectors

    Run some wood glue along the edge of the short benchtop. Then smooth the glue on with a scraper before pushing the short and long benches together. Now insert the bench connectors underneath and tighten them with your spanner. Do not fully tighten these bench connectors until you have also adjusted the top. You might need to use a mallet to tap the benchtops into place from the top to do this. Once the benchtops are fitted together correctly, you can fully tighten the joiners. 

  • Step 5. Secure benchtops into place

    Once the two benchtops are joined together, get someone to help slide them back into place. Clamp down the benchtop and screw it to the cabinet from underneath. Pre-drill holes at multiple points, then screw both benchtops to the cabinet.

  • Step 6. Connect the benchtop to the back panel

    To connect the benchtop to the back panel, you need to install the small angle brackets to the back of the cabinet. You can do this now or before the benchtops have been put into place. Aim to install one angle bracket into each cabinet section. Pre-drill your holes for each angle bracket and then screw them into place.

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions which came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings team member.
