The bathroom just wrapped up a renovation where two free-standing vanities were installed. There was ~30″ gap between the vanities which was perfect spot for an intermediate vanity that could be used while sitting.
The Plan and Materials
The plan was very primitive and only had a few overall dimensions, so nothing worth sharing. Essentially a slab of plywood cut to fit between two vanities and a drawer underneath. Since the vanity is floating, I needed to add some support(ledger) pieces to the vanities. The materials were a 3/4 plywood for top and support structure, 1/2 plywood for drawer sides, 1/4 MDF for drawer bottom, Poplar for false front and hardwood edge, iron-on edge banding material, 5mm ply for template, hardwood ledgers. It was all extra material from pas jobs, so no trip to lumber yard was needed…yay

Top and Drawer Supports
The entire project started out with a template from some 5mm plywood. Since this top had to fit between two vanity tops and a wall, I needed to make a template to ensure correct fitment and minimal gaps. I started with a bunch of measurements and then started cutting it down with track saw, bandsaw, and pull saw. It took about 4 tries, but eventually I had it fitting pretty nice.
The top was 3/4 plywood and was cut out using the template. Next step was to add something to hang the drawer slides from and add some stiffness to the top. So, I cut some strips of 3/4 plywood and screwed/glued them to the bottom.
Drawer
The drawer was made from 1/2 plywood at 3″ tall and I used rabbet joints in each corner (via router table). I also glued the 1/4 MDF bottom into place in the corners for more strength. I like to test my fit with the actual drawer slides before gluing up the drawer. Once I am happy with the fit, I take it out and glue it up.
False Front and Edging
The very front edge of the vanity received a hardwood edge (poplar), which later received a 3/8″ round over. The other vanity edges and top of the drawer received some iron-on edge banding to conceal their plies. The drawer false front was cut from the same poplar board as the edge, but was milled about 5/16″ thinner. So it could be recessed back a bit from the edge. Making my life a bit easier.
Sanding and Finishing
The sanding is inevitable, but has to be done. Started with 80, worked up to 180. Then, I used grain filler for the first time to try an make the plywood as smooth as possible. I did one coat and sanded it back. This was not enough, since I could still make out the grain after adding the paint. Next time, I know
My local BM store did not have any BM Advanced in a Dark (4) base. So, I opted for another option, which was INSLX – Cabinet Coat. I have to say, it sprayed pretty nice with about 5% water or so and it was self priming. This was after the first coat. As you can see the grain is still pretty visible.
I sanded the first coat back and sprayed. Then sprayed two coats of poly on top and the drawer. The reason I added poly to the painted surface as “just in case” measure. I read that the cabinet coat collected dust really easily.
Finished Pictures
I added some cleats/ledgers/supports to the existing vanities and set the top on them. I used screws (from bottom) to hold the top into place.
