Do You have a spare closet or cupboard that isn’t giving you all it could ? You can turn it into a functional pantry with these DIY floating corner pantry shelves. 

Plan Your Layout

For reference, the overall dimensions of my closet space were 48″ wide and 22″deep. The depth on each side of the door was 6″ on the right and 6.5″ on the left.

Your dimensions will be specific to your closet size and materials used.

I used some construction paper cut to the final size of my floating shelves (2.5″) to play with spacing. The above image shows the spacing I ended up using. My two lower shelves are 12.25″ deep but don’t wrap around to the sides. My upper shelves are 8″ deep in the back and 6/6.5″ on the sides.  

Frame in the Supports

Due to the width of my closet space, I needed strong supports in order to hold anything of significant weight. Basic cleats weren’t going to be sufficient. Using the 2 x 2 scrap, I created the support framework.

I located and marked the studs on the wall for a good fix.. Then I attached a 2 x 2 support across the back and sides for each shelf. Walls, corners, make sure that you’re checking for level multiple times throughout this process.  

I used more 2 x 2’s to frame in the shelving and filled this in with some shorter cross braces shown here. 

All of the framework pieces were screwed into the studs using 3" screws and then attached to each other with No Nails glue.

Cut and Dry Fit Shelving

I used my circular saw and a Kreg Rip Cut attachment to cut ¾” plywood for the tops and ¼” for the bottom. This attachment makes cutting large stock a breeze, and it keeps everything straight and consistent if you’re making multiple cuts of the same size.  

Once all of my cuts were made I did a quick dry fit to ensure everything fit as neatly as possible.

For the wraparound shelves, I had to cut 3 separate pieces (one for each side and one for the back). I made them fit as tight as I could and used wood filler to make it look as seamless as possible.  

At this point, you could go ahead and give the shelves one coat of primer and one of paint before installing, like I did. Just know they will likely need an additional coat or two after install.

I used my nail gun and some adhesive to attach the ¾” plywood pieces to the tops.  Clamps will come in handy here to act as a second set of hands and keep everything aligned and flush.

When you’re planning your spacing, be sure you can still get your nail gun in between shelves or build them in by levels. Mine ended up being a really tight squeeze with a lot of awkward angles so be sure to take all of these things into consideration in the planning process.  

For the bottom 1/4″ plywood pieces, I used a quick grab adhesive like No Nails and clamps to work as a second hand until I could get them securely nailed into place.  

Once your top and bottom pieces are all nailed in place, you will have a wood “sandwich” of sorts. I planned my material dimensions so that a 1 x 3 piece of pine would cover the front of it perfectly. Remember, nominal lumber dimensions are different from their actual dimensions so a 1 x 3 is actually 2.5” wide.  

I used my nail gun to attach the 1 x 3 pieces of pine right to the front of the “sandwich” and it covered everything up perfectly.  

Finishing

Walls are rarely even, and corners are very rarely square in home construction. Especially in a space like a cupboard. No matter how accurate you try to be with your cuts, you will more than likely still encounter gaps against the walls and other areas that need to be filled.  

Any gaps in the shelves I covered them with wood filler.  

I also used wood filler to cover any seams where the wood met wood and caulk to fill in any gaps between the floating shelves and walls. Don’t skip this as it will be the finishing touches that make your shelves look amazing!

Once the wood filler is dry you can sand it down smooth and apply your final finish.  

I use some leftover white enamel trim paint that we had lying around to finish everything off.  Be sure to allow your finish to dry and cure for the appropriate amount of time before restocking your shelves.
