These floating corner shelves were a fun challenge.

I glued 2 triangle pieces of 1/4” plywood together with a 3/4” spacer and then attached a trim piece with glue and brad nails.

The wall supports are attached with drywall using plastic wall anchors.

The tricky part was getting the angle right, because my wall wasn’t square. It tested my 9th grade geometry skills. I used an adjustable angle finder to get the right fit.

The finished shelves were then slipped over the hidden supports.

I plan to paint it white to match the trim in room.

Just finished up a set of these. Brand new house but the corner wasn’t square. Both walls were very short so the drywall was not flat.

Yours came out nicer than mine!

Do you have a picture of just the supports?

Would give me a better idea of what you’re talking about. :)

Thank you.

Awesome idea. I can think of a few places in our house where this would come in handy. Thanks for sharing the technique for all of us to learn from.

Thank you for revising your pictures… makes more sense now.

Do you just slip the shelves over the supports, without any screws for security?
(and they won’t tip / slide off?)

The shelves slip tightly over the wall supports, but in my final installation I think I will secure them with a brad nailer.

I used a nylon Zip-It anchor into 1/2” wallboard. It has a 65 lb tension load capacity and 70lb shear load capacity. Each support has two screws. The shelves are very solid, and I think I will have more than enough strength to display glassware.

For glassware – what you did is no problem. I did some floating shelves recently for speakers (I still ask myself why I did that. So much trouble but it looks nice) – and finding studs in the wall was a pain. We designed it similar to yours, though very thick for a different look. To secure it, we used 1.5 inch flat ended wood screws into the braces (the braces were quite thick also). The shelves have not budged an inch. In your case, it looks like you should indeed use the brad nailer to secure it just so a shelf does not decide to take off on it’s own (or a child or a dog/cat/animal gives it a helping and or paw).

Have your say...
