Draw measurements quicker

If you only need to cut off a small amount of timber from the end of a board, here’s a great tip to make drawing up the measurements quicker and easier. Rather than going through the process of marking everything up with a ruler, you can simply use your fingers as a guide. Just make one mark, in from the edge, to the depth you want to cut, and hold the tip of your pencil over it. Press into the end of the timber with your middle finger and hold the pencil in position with your index finger pressing down on the timber face. As you steadily slide along the edge of the timber, the pressure from your middle finger will keep your pencil stable and draw a straight, accurate line every time.

Step by Step Instructions

1 Measure up where your bathroom vanity will sit
2 Cut access holes in the bathroom vanity for pipes
3 Install the bathroom vanity
  • Step 1. Measure up where your bathroom vanity will sit

    Use a measuring tape and pencil to mark out on the floor where you want your vanity.  Then work out the position of your waste and water pipes. Measure from the edge of where your vanity will be to the middle of each pipe. Then get measurements from the back wall to middle of the pipes.
  • Step 2. Cut access holes in the bathroom vanity for pipes

    To make this step easier, remove the backing panel from the vanity cabinet. Then transfer your pipe measurements to the base panel and use a hole saw to cut the holes for the pipes. Once the holes are cut, replace the back panel and put the vanity in position over the top of the pipes.
  • Step 3. Install the bathroom vanity

    Check the vanity is level, then use your hammer drill to put two screw holes through the back rail of the cabinet and into the wall. Now push wall plugs into the holes, trim them to length with a knife and drive screws through the cabinet into the wall. Finish the job by checking your vanity is still level, then put your drawers, doors, benchtop and sink in place. Now you are ready for the plumber.
