DIY Floating Box Shelves With Hidden Storage

4 Materials
2 Hours

These rustic shelves look so good in my guest bath! They were so easy to make and the added bonus is: the tops open up for extra storage inside!

So here’s how we made them:

We used some of the old weathered pine

we’ve had since 1988 when we lived in Northern California (you can read the story about that HERE)

But don’t worry — if you don’t have authentic old weathered wood — there’s a stain you can use that will weather it.

Basically, you’re going to make a box that’s 24" long, 7 1/2" deep, and 4" high

Cut a front and a back piece that’s 24 long by 4 high

Cut a top and bottom that are 24 x 7/12 minus 2 thicknesses of your wood all the way around (the tops, bottoms and sides will be nailed inside these pieces)

This is how it will fit together.

Next cut 2 sides 7 1/2 x 4 minus 2 thicknesses of your wood all the way around.

Nail the front of the box to the bottom and sides.

Then nail the back on.

Cut 2 pieces of wood to go inside the ends that are just shorter than the thickness of the top and nail them to the sides.

This is what will support the top of the shelf.

If you used weathered wood, you’re going to want to stain the raw edges with ‘weathered wood accelerator’ stain so it blends with the rest of the shelf.

If you didn’t use weathered wood but you want that look, stain the whole piece with accelerator stain. Let it dry overnight.

Apply a coat of clear finishing wax for a subtle low luster finish

Screw the back of the box to studs in your wall making sure it’s level.

Place the lid on your box shelf and you’re done.

Just remove the top for access to storage inside.

Who couldn’t use a little more storage in the bath right??

    What color paint on walls and what is the brick stucco on the half of the wall. Thanks

      Hi Dturkey55 --

      The paint color is a custom match of a paint color we had in a rental so I don't have a name for it -- sorry. The wainscot is 2 x 4 honed Carrera marble.

    They are beautiful! I’m wondering, since you are putting things on top of them as well as inside, is it kind of a hassle to have to remove everything you have sitting on top each time you need something from inside, or have I misunderstood how it’s put together?

      Yes that’s such a good idea; I wanted some kind of shelving but to have it dual purpose is such a great idea

    If I understand correctly the top actually sits down inside the box on the inside sides you made, how do you lift the top off to get inside without a handle, knob or grab hole???

      Hi Junie --

      Actually, on mine there's a knot hole on the edge of the box that allows me to lift the top out. It would be a good idea to put some kind of small knob or even a little screw in the back that you could grab onto to lift the top off.

    It’s going to be way to heavy in the front. Floating shelves must have a rod which is secured to the wall by a bracket and runs though a hole drilled in the back of the unit to supports the entire shelf. This design seems dangerous.

    Your shelves look fabulous! What a great idea. I can think of so many other rooms that these could be used in. Everyone could use a little more hidden storage. Thanks for your creative tips!
