Drifting wall surface shelves is an elegant, space-saving method to update any area. Whether you want to display books, style, or plants, a floating rack provides a tidy, modern look without noticeable support. The most effective component? You can make one on your own —even if you’re a do-it-yourself novice!
In this guide, you’ll learn how to build a floating wall shelf from scratch, including the materials you’ll need, how to install it properly, and smart tips to ensure your shelf is safe, level, and stunning.
What is a Floating Wall Shelf?
A floating wall shelf is a type of wall-mounted shelf that appears to “float” without visible support. Instead of being held up by traditional brackets, floating shelves use hidden mounting systems or hollow-box designs that conceal hardware inside the shelf itself.
This minimalist approach works great in:
- Bedrooms
- Living rooms
- Bathrooms
- Offices
- Kitchens

Step-by-Step: How to Build a Floating Wall Shelf
Step 1: Choose a Location
- Decide where you want to install your shelf.
- Mark the height and width of the wall using a pencil and level.
- Use a stud finder to locate wall studs for secure mounting.
Tip: Mounting to wall studs is stronger than using wall anchors alone.

Step 2: Cut the Wood to Size
Decide on your shelf size (e.g., 24″–36″ wide and 8″–10″ deep).
- Cut the front face of the shelf using a solid wood board.
- Cut two side panels to the shelf depth minus the thickness of the wood.
- Cut top and bottom panels if you’re making a full hollow box.
- Cut a cleat or internal frame from 1×2 wood for wall mounting.
Example shelf dimensions:
- Width: 30″
- Depth: 9″
- Height: 2.5″

Step 3: Build the Shelf Box
- Lay out your cut pieces.
- Assemble the hollow shelf box using wood glue and screws or nails.
- Attach the top, bottom, and sides to the front face.
- Leave the back open—this is where the cleat will slide in.
Optional: Sand the edges smooth before assembly for a cleaner finish.

Step 4: Build and Mount the Wall Cleat
- Create a support cleat by cutting a piece of 1×2 or 2×2 wood slightly smaller than the width of your shelf.
- Drill this directly into the wall studs at the marked location.
- Use a level to ensure the cleat is perfectly straight.
- If you’re not hitting studs, use heavy-duty drywall anchors or toggle bolts.
Important: The cleat must support the shelf’s full weight, so use high-quality fasteners.

Step 5: Slide the Shelf Onto the Cleat
- Carefully slide the hollow box shelf onto the mounted cleat.
- The cleat should fit snugly inside.
- Secure the shelf by driving wood screws from the top or bottom into the cleat inside.
Pro Tip: Drill pilot holes to prevent the wood from splitting.

Step 6: Sand, Stain, or Paint
Once the shelf is mounted, finish it to match your room’s style.
- Sand the entire surface for a smooth feel.
- Apply wood stain with a cloth or paint with a brush.
- Let it dry, and then apply a clear polyurethane coat for added durability.
