Step by Step Instructions

1 Mark the centre of your benchtop
2 Mark an outline of the sink with your template
3 Cut the template outline into your benchtop
4 Attach the brackets to the sink
5 Insert the trough and tighten the brackets
  • Step 1. Mark the centre of your benchtop

    Use your tape measure to find the centre of the cupboards you want to put the sink over. Mark this spot on your benchtop with a pencil, this is where you want the centre of the laundry sink to be. Now draw a straight line from this mark to the back of the benchtop.

  • Step 2. Mark an outline of the sink with your template

    Centre the sink template on the benchtop, in line with the pencil mark you’ve drawn from the front of the bench to the back. Once the template is centred, move it back towards the wall a little, so that the trough won’t obstruct the cupboard doors. Check the template is straight and leaves enough room for taps to be installed against the wall. Now draw around the template with your pencil.
  • Step 3. Cut the template outline into your benchtop

    Put on your safety glasses, dust mask and ear muffs. Start by drilling a large pilot hole in the benchtop on the template outline. Use this point to start cutting out the bench with your jigsaw. In the back corner, where the curve of the template is close to the wall, use the hole saw to drill a hole, this will help the jigsaw to cut more easily around the corner. Use the jigsaw to then cut around the template. 
  • Step 4. Attach the brackets to the sink

    Before putting the sink into place, attach the eight brackets into their locations under the lip of the trough. Different sinks have different brackets, so follow the instructions to make sure they are attached correctly and keep your trough in place.

  • Step 5. Insert the trough and tighten the brackets

    Insert the laundry trough into the hole in the benchtop, make sure it is sitting straight. With a screwdriver, tighten the brackets so that the trough is secured underneath the benchtop. Repeat this step until all of the brackets are tight and the trough is secure.
