Steps

1Choose your timber

When choosing the timber for your vanity make sure it's straight across all planes. Lift the plank and look along the edge, making sure it isn't twisted or bowed. Also, make sure the timber is the same width. Our vanity will have two hand basins and be 1500mm long.

2Prepare your bathroom

Before you start this project, determine where the vanity will go. Use a licenced electrician and plumber to install the necessary power outlets and plumbing fixtures.

3Sand the timber

Ensure the two planks for the top of your vanity are face side up. Sand and clean the edges and faces to be joined. They don't have to be sanded smooth, if they're a little rough it'll help the glue adhere to the surface.

4Join the two pieces of timber together

Stand the timber and liberally apply glue to the joining edges. Clamp the two pieces of timber together. Place offcuts of timber between the clamps and the wood to protect the timber. Put two sash clamps on top of the wood to make sure the timber doesn't bow.

5Remove any excess glue

Use a chisel to remove any excess glue from the top of the boards. Wipe the excess glue onto a rag.

6Make the boards level

To make the boards level, place one block of offcut timber underneath and another on top. Use a hammer to hit the offcut timber on top of the wood until your spirit level indicates it is level. Clean off any excess glue and leave it to dry.

7Remove the clamps

Once the glue has dried, remove the clamps. Use a chisel to carefully remove any excess glue from the top and bottom of the timber.

8Sand the timber

Use your belt sander to sand the timber until it has a nice, smooth finish. Remember to always sand with the grain.

10Choose the top of your vanity

As well as selecting the best piece for your top, choose which front edge will be the one that faces the room. Once selected, mark them both with tape.

11Cut a 45-degree mitre at one end

Once you've chosen the top of your vanity, clamp the timber to your workbench. Wrap masking tape around the timber where you're going to cut. Use the circular saw to cut the timber at a 45-degree angle.

12Measure and mark the length of your vanity

From the mitre cut, measure how long you want the vanity to be, ours is 1500mm. Mark this and wrap masking tape around the timber where you're going to cut.

13Clamp and cut the timber

With the timber clamped to the workbench use a mitre saw to cut the other end of the top of the vanity at 90 degrees.

14Measure and mark the panels

On the second piece of timber, measure and mark for the end, base and return panels. The lengths we used were:

  • 350mm (end panel)
  • 690mm (base panel)
  • 200mm (return panel)

Also, we added a few extra centimetres to make the timber more manageable.

15Cut the timber at 90 degrees

Clamp the timber to the workbench. Wrap masking tape around where you're going to cut. Use a circular saw to cut the three pieces of timber at 90 degrees.

16Measure, mark and cut at 45 degrees

Take the three pieces of timber and measure and mark them at 350mm, 690mm and 200mm. Wrap masking tape around the timber where you're going to cut. Clamp the timber to the workbench and cut it at 45 degrees. Remember, they need to be in opposite directions – except for the return panel, which is only mitred at one end.

17Sand the edge of the return

Once you've made all your mitre cuts, sand the edge of the return. This will be on show, so it needs a smooth finish. Mark each piece of timber so you know which piece is the end, base and return panels.

18Measure, mark and cut the rebate

Place two brackets on the back edges of the timber that attach to the wall. Mark where they will go. Use a set square to ensure your line is square and measure the distance. Clamp the timber in a vice and use a router to cut a rebate in the back edges for the brackets.

19Join the mitred timber

Put the edges of the timber that will be exposed face down before gluing, this will ensure the face edges are aligned. Liberally apply glue to the mitred edges. Tape the pieces of timber together and use a nail gun to fix them permanently.

20Attach the end piece to the top of the vanity

Apply glue to the end piece where it will join to the bottom of the vanity. Stick the two pieces together with masking tape. Use a nail gun to secure them.

21Attach the shelf to the vanity

Apply glue to the end piece and the shelf of the vanity where they will join. Line up the shelf and end piece. Tape the two pieces together, then use a nail gun to join them.

22Attach the brackets and putty holes

Place the two brackets in the rebated edge. Attach to the vanity using a drill and screws. These will give added strength to your vanity. Putty and fill any holes or cracks in the timber. Let it dry and sand it back with 120-grit sandpaper.

23Varnish the timber

To bring out the natural look of the timber we're using Cabot's Cabothane Clear varnish. Let the first coat dry and lightly sand it back. Wipe away any sawdust. Apply at least three coats, sanding between each coat.

24Measure, mark and drill holes for the reo bars

Transfer the locations for the holes for the reo bars to the back of your vanity. Use the drill and an appropriately sized drill bit to drill the holes in the back of the vanity for the reo bars. Drill the holes into the vanity a little deeper than the length of the reo, this allows for the excess glue.

25Lift the vanity into place

Have someone help you lift the vanity into place, so that the holes are lined up with the reo bars. Place something underneath the vanity to help support its weight.

26Apply glue to the reo bars

Liberally apply high strength glue to the reo bars.

27Tap the vanity into place

Push the vanity against the wall so that the reo bars go into the drilled holes in the vanity. Use a rubber mallet to gently tap the vanity into place. Use a spirit level to check that it's straight.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. 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. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
