We needed a space to store bathroom supplies, such as extra toilet paper, toothbrushes, & hair accessories in our tiny powder room. We used the space above the toilet to create floating shelves to hold all the necessities.
Then we cut some finished plywood for the shelves & my husband used a router to create the cap for the front of the shelves. Depending on how think you want the shelves, you could probably use a piece of trellis wood for the end.
Next, we installed the top & bottoms of the shelves by nailing them to the braces. Finally, we nailed the fronts to the shelves.
