They were beautiful but unfortunately, they just weren’t sturdy enough to stand up to two preschool boys.

So I removed them to use elsewhere and have just been tossing their clothes into these cubbies for the past year or so.

It still worked just fine but it definitely did not look great.

I’ve been thinking about making new wooden storage bins for a while.

I haven’t been able to find anything in stores that was the size and look I was going for so I decided to make them myself.

And when CedarSafe offered to send me some of their gorgeous cedar planks, I knew they would be perfect.

Cedar is perfect for DIY projects like this one. It naturally repels many of my least favorite bugs like moths, cockroaches, and silverfish.

It has a beautiful grain and doesn’t need to be finished with any type of stain or varnish. And it smells amazing.

Seriously, my husband cannot stop talking about how good this wood smells. (And anything to help my boys’ room smell great is a major plus!)

How to make Custom DIY Wood Storage Cubes

These cedar boxes can easily be made in any size to perfectly fit any size shelves or cubbies.

My cubes are 13.5″x 13.5″, but it is really simple to make these wood cubes any specific size you need.

The main thing to remember is that you need to cut the planks for the two side panels of your boxes 1/2 inch shorter than the front and back.

The bottom panel will also be 1/2 smaller in both length and width than the overall box size because it will tuck into the bottom of the box.

I made a quick graphic for another post I wrote on building DIY wood boxe s and it works well here as well.

This diagram should make it easy to figure out your measurements for any custom size box.

Just substitute the sizes you want for the height, width, and depth.

how to measure to make diy boxes in any size

For my 13.5″ cubes, I cut the cedar planks for the sides 13 inches long and the cedar planks for the front and back 13.5 inches long.

The inner supports are 12.5″ high and the bottom is 13″ x 13″.

Cut the cedar planks to size

Once you’ve decided what size boxes to make, you can start cutting your cedar planks to the correct lengths.

These are tongue and groove planks so they join together perfectly.

Since they are often used for plank walls, they also have overlaps at the edges along the ends of each plank.

Before cutting your plank to length, remember to cut off these overhangs to make a straight edge.

Since you need to cut quite a few plank pieces to the same lengths, it is much faster if you cut multiple planks at once.

I used my miter saw for quickly making these cuts, but if you don’t have a miter saw, most other power saws would also work well.

You may also need to rip the top row of planks to the correct height. I considered making my boxes slightly shorter so I could avoid needing to make more cuts.

But when I held up some boards to compare the two heights, I strongly preferred the custom look of adding an additional row of ripped planks.

It is a bit more work but looks so much nicer.

I used a table saw to rip my planks down to size and it was really quite easy.

If you don’t have a table saw, a regular circular saw would also work fine.

To make my 13.5″ boxes, I cut the top row of each side 2 1/4″ high.

Once you have your board pieces all cut, use sandpaper to sand any rough edges smooth.

Cut the handles

Cutting the handles looks complicated, but it really isn’t. You just need to cut two circular holes using a hole saw and then connect them.

A hole saw is a small circular saw that attaches to a drill.

Even though they are pretty easy, you can always skip the cut out handles if you’d prefer.

These boxes would also look great with nice drawer pulls attached as handles.

Before cutting the holes, mark where the center of each circle will be. I used a 1 1/4″ hole saw to cut my handles.

I marked the center of each hole 1.5 inches from the center of the plank to make handles that are approximately 4″ long.

Be sure the marks are also centered top to bottom on the plank.

marking wood for cutting handle

Place the center of the hole saw at each point you marked and cut out the holes.

It helps to back the cedar planks with a piece of scrap wood before cutting the holes.

This will keep the back of the plank from blowing out and help ensure a neater cut.

Use a straight edge to make straight lines between the two circles you cut and cut them out with a jigsaw.

Use 220 grit sandpaper to sand the edges of the handhold smooth.

Glue the cedar planks together

Once the handles are cut, you can form the sides of the box.

Simply lay out the planks for each side including the front and back and glue them together with wood glue. (Just run a small bead of glue along the groove of one board and then insert the tongue of the next board into the groove.)

Make sure that the pieces with the handholds are in the correct spot. Wipe away any excess glue and allow the glue to dry thoroughly.

Cut the box supports

The boxes need interior support to make them sturdy. I used inexpensive 1″x 2″ boards as supports.

Cut these an inch shorter than the height of your box. You will need four supports for each box you are building.

Use sandpaper to sand off any rough edges.

Assemble the boxes

Lay one of the 13″ box sides facedown on your workspace.

Glue two of the 1″ x 2″ supports against the outer edge of each side, leaving 1/4″ space at the bottom of the planks. (This space is where the box bottom will go).

Once the glue has had some time to dry, turn the planks over and use small brad nails to securely attach the planks to the supports.

One nail in each corner should be enough. The wood glue alone might be enough to keep these storage cubes securely attached, but I wanted to make sure they are extra sturdy.

Especially since they are going to be used daily.

These nails are visible on the outside of the box, but they are so small, they really aren’t very noticeable.

Place the back of your box facedown on your work surface. Using wood glue on the 1″x2″ supports, attach the two sides of the box to the back.

Be sure to line up the edges carefully. You may want to use some scrap wood to help hold the sides in place until the glue dries.

Add wood glue to the wood supports showing and place the front of the box on top of them, being sure all of the edges are lined up.

Allow the glue to dry and then use a small nail in each corner to secure the box front and back to the sides.

Cut the bottom of your box out of 1/4″ plywood. Use wood glue and brad nails to attach it to the wooden supports inside the box.

I added furniture sliders to the bottom of each box to make them easier for my kids to slide them in and out.

And since the cedar doesn’t need any type of finish or sealer, that’s it! Not having to stain and seal these saves so much time.

Storage cubes for tight spaces

If you look at the shelves in my sons’ closet, you can see that there isn’t room to slide these large boxes into the outer cubbies because of the doorframe.

But with a simple adjustment, I was able to make them work. For the cubes for the outer cubbies, I built each box in two halves.

I built the fronts and backs the exact same way as the other boxes, but made each side in two halves with extra supports for the cut edges.

I also cut the box bottoms in half. That way I can move the back half of the box into place and then slide the front half in front of it.

I attached simple hook and staple latches at the top of each side to connect the two halves.

This way they are easy to move into place and I can unlatch them to remove them in the future.

Thankfully, it works great.

Finished DIY Wood Storage Cubes

These storage cubes look perfect in the boys’ closet. Just look at that beautiful wood grain.

I love how the natural cedar is neutral enough to work with any decor without being boring.

And that wood grain is just beautiful against the clean lines of the closet shelves.

Definitely better than anything I could have bought from a store.
