Step 1 Apply PVA to bottom edge of 1 side and position it flush with 1 short end of bottom.
Step 2 Apply PVA to top edge of side, then bring in the top and place it in position, using other side as a prop to take weight of top and hold it in a level position.
Step 3 Clamp this side of assembly together so side is flush with edges of top and bottom.
Step 4 Repeat Steps 1-3 to secure second side in position. Work quickly to make any adjustments necessary and wipe away any excess PVA using a damp rag.
Step 5 To secure top to both sides, drill pilot holes for an even spread of long nails (we used 4 at each join). Using a drill bit that is slightly narrower than your chosen nails, drill to about half the depth of the nails’ length.
Step 6 Hammer in nails, then follow up by tapping all nails using nail punch so head of each nail sits just below the surface of the top.
Step 7 Flip assembly over and repeat Steps 5-6 to secure bottom to sides. Remove clamps and flip assembly back upright.
Step 8 To hold assembly square and to give you something to fix it to the wall, you need to fit a support batten. Apply PVA and position support batten flush to the underside back edge of top (what will be the wall side of the vanity). Use clamps to hold in position.
Step 9 From outside of sides, drill pilot holes through sides and into support batten (we drilled 2 evenly spaced holes on each side). Hammer nails through pilot holes and punch nail heads as before.
Step 10 Using wood filler, fill nail holes. Let dry. Sand all surfaces and thoroughly wipe away all dust.
Step 11 Coat assembly and centre panel, if using, in liming wash. You may only need 1 coat, or apply a second for greater depth of colour. Let dry.
Step 12 Predrill through support batten and fix vanity in a level position on your wall using suitable fixings (we secured ours directly into wall studs).
Tip Use suitably sized timber offcuts to hold the vanity at the correct height while you secure it to your wall.
Step 13 You or your plumber may make necessary cut-outs for plumbing using a drill fitted with a hole saw. Touch-up cut edges with liming wash prior to installing plumbing, if necessary. Let dry.
Step 14 Once tap and basin is installed, depending on whether you’ve elected to use basic or decorative drain plumbing (such as chrome finished) you may or may not wish to slot the centre panel in position to disguise the drain plumbing – it’s your choice!
