First, let me say that since this was built for a very specific space, the measurements might not work for everybody. In fact, I would be surprised if they do. If you want to try to replicate this, be sure to take your own measurements rather than going off of what we did.
2 1″ x 8″ x 8′ boards (depending on your height, you may only need 1 board)
1/4″ plywood to fit the back of your shelf, ours was 3′ x 1′ approximately
To determine our measurement, I first measured the width of the empty space we wanted to fill. Ours is 12″ wide.
Then I took a look at the sink cut-out on the countertop. I didn’t want this coming too close to the edge of the sink because I thought it looked force and I didn’t want it getting splashed too much. Ours is 7″ deep. When I measured the depth, I went from the wall to the front of the shelf as opposed to the front of the backsplash (more on that later, though).
For the height, I didn’t want it to be even with the top of the mirror. Perhaps if the mirror frame was white, it would have looked nice to tie it in and make it look cohesive. But since we were working with 2 different finishes, I wanted our shelf to be a bit higher. Ours is 3′ high.
The only thing you really need to pay attention to, is if you countertop has a backsplash like ours does. We got notches out of the bottoms of our sides to accommodate the backsplash, so it would sit as flat as possible. We could have just had it freestanding on the counter and avoided having to cut out the notches, but we wanted to attach it to the wall and not have a gap between the wall and the back of the shelving unit.
Be sure to take note in the picture below that when we were marking the sides for the notches, we placed a scrap piece of 1/4″ plywood behind it to account for the backboard we would be putting on later.
To cut out the notch, we held one of the sides against the side of the backsplash and just traced it with a pencil. We cut it out with a jigsaw, making sure to err on the side of caution for the first cut. You can always go back and cut more off, but you can’t add wood back if you cut too much that first time!
Using a speed square to make sure you have right angle for your shelves, just nail your sides into the shelves.
Move onto your next shelf repeating the steps to square your shelf and then nail the side into it.
Once you have one side down, flip it over carefully and nail your other side onto it.
Then lay your 1/4″ plywood on the ground and play the shelf on top of it. Trace the outline for the backboard for your shelf. Cut it out with a jigsaw and then attach to the back of the shelf using nails.
After this, all we had left to do was cut a hole in the backboard for our outlet to come through. Then we screwed it directly into the wall, caulked it and painted it.
It really was a straight-forward and simple build and filled in that awkward spot beside the mirror perfectly! Plus, you can’t beat extra storage that’s free!
