We get asked this a lot — and the answer depends on which type of floating shelf you're working with.
"Floating shelf" means different things to different people. To some, it means the mounting hardware is completely concealed — you see the shelf, nothing else. To others, it just means no visible support brackets or gussets underneath. Both are legitimate. Both mount differently.
Here's how each one works.
What "Floating" Actually Means
The common thread is a clean, minimalist look after installation. No exposed corbels, no diagonal braces running down the wall. The shelf appears to come straight out of the wall.
But not all floating shelves have concealed hardware. A shelf with a 90° return flange along the back — like our Simple Stainless Floating Shelf — mounts with screws through that flange. The screws are there, but they're not jumping out at you. A lot of our clients call this a floating shelf, and that's fine. It fits the spirit of it.
A fully concealed floating shelf is a different animal. The hardware is completely hidden behind the shelf face. Worth understanding both.
Mounting a Fully Concealed Floating Shelf
Fully concealed shelves use a bracket-and-shroud system. The bracket mounts to the wall first. The shelf itself — essentially a hollow box — slides over the bracket afterward.
Step 1: Find your studs
Most bracket systems have slotted holes so you can shift position and hit a stud. Find them, mark them. Mounting into a stud gives you the strongest hold. If you can't hit a stud, drywall anchors work — just match the anchor to your wall type (drywall, tile, masonry, plaster).
Step 2: Get your position marked
Put a small piece of tape or a light mark on the wall where you want the shelf to land. Knowing your target before you start drilling saves a lot of frustration.
Step 3: Mount the bracket
Drive one screw — don't fully tighten it yet. This gives you something to pivot off of while you dial in the level.
Step 4: Level in both directions
This is the step people skip. You need to check two things:
- Is it level side to side?
- Is it tilting toward or away from the wall?
A wall that's slightly out of square can throw you off. If the bracket is angling down or up even a little, objects will slide. Fix it now with shims — top or bottom of the bracket, wherever you need — before you tighten anything down.
Once it's level both ways, drive the remaining screws and tighten everything down. Check level again.
Step 5: Slide on the shelf
The shelf slides over the bracket. Depending on the system, it'll lock in place with small screws, magnets, or another retention method. Check level one more time after it's on.
Mounting a Flange-Style Floating Shelf
Shelves like our Simple Stainless Floating Shelf have pre-drilled holes along the back flange. The install is more straightforward, but there's less flexibility — so precision matters more upfront.
A few things to consider before you start:
The holes aren't slotted. Slotting them would compromise the finished look. If one of those holes happens to land on a stud, great — that'll give you extra holding strength. If none of them do, that's fine. Use quality drywall or masonry anchors.
Step 1: Mark your hole locations
Hold the shelf against the wall in its final position. Put a level on top. Once it's where you want it, mark through one hole — typically near one end. Set the shelf down.
Step 2: Install your first anchor and screw
Drill out for your first anchor, set the anchor, and drive that one screw. Leave it slightly loose.
Step 3: Level and mark the rest
With the shelf hanging on that one screw, rotate it until it's level. Mark the remaining hole locations. Remove that screw, take the shelf down, drill and set all remaining anchors.
Step 4: Mount it
Put the shelf back up and drive all screws. Our Simple Shelf ships with stainless decorative screw caps that sit over the heads — they give the finished installation a cleaner, more polished look.
One note on shims: Shimming is much harder with this style. If your wall is out of square, you don't have a lot of options — any shim material would be visible. This is why the bend angle at the back flange matters. A shelf that's not bent to a true 90° will sit crooked regardless of how carefully you install it. It's something we pay close attention to in fabrication.
Anchor and Hardware Notes
For standard drywall, the included anchors work fine. Our Simple Shelf comes with anchors sized for a #8 screw.
For masonry, plaster, or tile, consider a Fischer DuoPower anchor. They're a top-tier plastic anchor that works well in harder substrates.
If you're not sure what you have behind the wall, it's worth taking a minute to find out before you start drilling.
A Few Situations Worth Calling Out
Over a fireplace or outdoors: Heat and moisture will eventually degrade wood. If the shelf or its internal mounting components include wood, that's a liability in these environments. Go with a 100% metal shelf. Stainless is a particularly good option here — it handles both heat and moisture without corroding or warping.
Material options by shelf type: Fully concealed shelves are available in both wood and metal — lots of species, lots of finishes. Flange-style shelves are primarily metal, because wood can't be bent to form the return flange.
