How to Finish a Foyer Closet
Set the height of your rod, the “standard” is somewhere between 66 and 72″ depending upon who you ask or where you look. Set it to a comfortable height for you and your family or at a comparable height to any other finished closet.
Using your mark draw your level line on all three walls.
Using a scrap piece of wood against your level line butt it up against the side wall and use a straight edge to mark any slope. You will want to use this method on both sides of the back board and the side boards where they meet the back board.
Then measure for your back board, when using a tape measure for inside dimensions mark a line away from the corner so you don’t have to guess how long it is at the bend of the tape. I used a 12″ metal ruler. At your mark just add the dimension you measured out from the wall.
On all your boards you will want to make a compound miter cut. For the back board 2-3 degrees is plenty, for both of the sides you will want the compound cut to be 5 degrees.
Line up your saw blade with the marks transferred from your scrap piece of wood and cut your boards to the required dimensions.
So Why All These Compound Cuts?
When two square pieces of wood come together they come to a sharp point, drywall corners are rounded, if you install this without a bevel cut on the back then you will end up crushing the mud and tape in the corner eventually leading to a crack. The bevel on the back bridges this rounded corner.
On the sides if your corners are less than 90 degrees a bevel isn’t needed as the wood will pivot on the front edge, if your corners are greater than 90 degrees the wood will pivot on the back edge exposing a gap at the seam. If you bevel the back it will always pivot off the front and show a nice seam.
I only had a 1 degree slop on my rear wall, this is what the seam would have looked like if I didn’t cut it at that 1 degree and didn’t put a bevel on the back.
This is the same corner except with the slope and bevel cut, as you can see, it leaves a perfect looking seam.
Since this is going to hold winter coats and assorted crap on the shelf it needs a center support, so some quick work with a tube of caulk and a roll of tape I made a bit of a design and jig sawed it out.
Sand everything and finish as you desire.
I counter sunk all the screws and covered them with plugs to provide a nice clean finish.
