How to install a floating shelf on plasterboard, brick, or drywall: a step-by-step guide

A properly installed floating shelf seems to have no secrets: a clean line on the wall, no visible screws, no wobbling when you place something on it. But to achieve that result, there's a crucial preliminary step that cannot be skipped: knowing exactly what type of wall you have and what anchor it requires. This is the difference between a piece that lasts for years and one that comes loose after a few months.

Here is the complete step-by-step process for drywall, brick, and plaster, addressing the real, most common questions before picking up the drill.

Tools and materials you need

• Drill with an appropriate bit for your wall material
• Level (essential — a slight tilt is very noticeable on such a clean line)
• Pencil for marking anchor points
• The plugs and screws recommended for your model, according to the wall type
• Stud finder, if installing on drywall
• Measuring tape, to evenly space points if installing more than one piece

First: identify your wall type

The correct anchoring completely depends on this step, so don't skip it; it's the number one reason a shelf ends up loose.

Brick or concrete (masonry): This is the most forgiving surface for installation. It's easily recognized because drilling produces fine, consistent dust, and the drill advances with uniform resistance. A standard wall plug distributes the load well and supports the maximum weight of the piece without complications.

Drywall: This is where the most care is needed. Tapping gently with knuckles, a hollow sound indicates drywall without reinforcement behind; a duller sound usually indicates a stud nearby. Locate the stud with a detector, or use a specific heavy-duty anchor (Molly type or similar) that distributes the weight across the board instead of relying solely on the wall plug.

Plaster or fragile surfaces: It's advisable to locate the stud or internal reinforcement first, as with drywall. Plaster alone doesn't always reliably bear distributed weight and is more prone to cracking if the anchor doesn't distribute the load well.

Step-by-step installation

1. Choose the location and mark the height. Think about actual use: eye-level if decorative, lower if functional (entryway, bathroom, bedside table).
2. Locate the anchor point. For drywall or plaster, find a stud or use a heavy-duty anchor. For masonry, any point works with the correct plug.
3. Level and mark the drill points. The level is not optional; check it twice before drilling, because once the holes are made, there's no going back without leaving extra marks.
4. Drill and insert the anchors. Respect the recommended depth for your plug type; a drill bit that is too thin or shallow is the second most common reason for an anchor to fail over time.
5. Secure the hidden bracket to the wall. This is the piece that will hold all the weight, so make sure it's firm before continuing; gently pull on it before hanging anything.
6. Place the shelf on the bracket. In most models, it snaps into place or uses a final security screw to prevent it from shifting with use.

With the wall identified and the correct anchor, the entire process usually takes between 20 and 40 minutes per shelf, at a relaxed pace.

How much weight it holds according to the anchor and wall type

The Brera shelf, made of solid wood, supports up to 10 kg per shelf when properly installed on a solid wall (brick or concrete). On drywall, that margin is reduced if a specific heavy-duty anchor is not used; with it, it is still perfectly viable, only the maximum recommended weight changes.

If you prefer metal, both the Bergamo shelf and the Torino shelf follow the same logic: the wall, not the material of the piece, determines the actual load limit. A Torino on masonry can hold more weight than a Brera poorly anchored in drywall; the shelf's material is secondary to the anchoring.

As a general reference: on masonry, count on the maximum weight indicated by the manufacturer. On drywall with a heavy-duty anchor, allow a safety margin and distribute the weight evenly instead of concentrating it at one end. Heavy, specific objects (a large vase, a plant pot) weigh more than they seem; it's better to distribute several medium-sized objects than one single heavy one.

Common mistakes when installing a floating shelf

Not checking the wall type before buying the anchor. Using a generic plug on unreinforced drywall is the most common reason a shelf comes loose over time.

Skipping the level. A few millimeters of unevenness is almost invisible when drilling, but it's very noticeable once the piece is loaded with objects.

Overloading the piece beyond its capacity. Each model has a limit; exceeding it consistently eventually weakens the anchor, even if it seems to hold well at first.

Choosing an adhesive anchor for a piece that will bear real weight. Adhesive strips work well for very light accessories, but they do not replace a mechanical anchor when it comes to a shelf with books, plants, or ceramics on it.

Frequently Asked Questions

Can I install a floating shelf without drilling?

It is not recommended if the piece will bear real weight. To ensure a secure fastening, drilling and mechanical anchoring are always recommended; it is the only way to ensure the shelf holds stably long-term. Drill-free options (heavy-duty adhesive tape) are designed for much lighter items, like a towel rack, not for a shelf with books or decorative objects.

What anchor do I need for drywall?

A specific heavy-duty anchor (Molly type or similar), which distributes the weight over the board instead of relying solely on the wall plug. If you can locate a stud with a detector, that's better as it's the strongest point on the entire wall.

Can a heavy shelf be hung on drywall?

Yes, as long as you use the appropriate anchor and, if possible, anchor onto a stud rather than just the board. Without that reinforcement, drywall alone does not distribute heavy loads well, and the anchor may eventually give way over time, even if it seems to hold at first.

How to drill into drywall without damaging it?

Use a fine drill bit to mark the exact point before using the final drill bit, and drill at a moderate speed to prevent the board from cracking around the hole. If you notice the drill advancing with hardly any resistance at a specific point, you are probably between studs; check the location before continuing.

Can a floating shelf be removed from drywall without leaving a large hole?

Yes. When the anchor is removed, the plug holes remain, the same size as when installed, minimal damage that is easy to cover with a little spackle if you ever change your mind or move.

How long does it take to install a floating shelf?

Between 20 and 40 minutes per piece, once the correct anchor point is located.

Is installing the Brera different from the Bergamo or Torino?

The process is the same: identify the wall, locate the anchor, level, and secure the bracket. The only difference is the maximum recommended weight according to the material and model.

With the wall identified and the correct anchor, installing a floating shelf is a half-hour job, not a major renovation.
