How to Install a Floating Shelf: A Step-by-Step DIY Guide 2026

Installing a floating shelf isn't a difficult job, but it needs to be done with precision. There are various types of hidden supports for mounting open shelves that ensure a better aesthetic result than visible brackets; moreover, the space to leave in height between one shelf and another is reduced, and the installation of staggered shelves in width is also facilitated, allowing better use of the wall. Based on the thickness of the wall, we can use pairs of shelf plugs or metal supports in which the two protrusions that penetrate the shelf are made. The diameter of the plugs must be chosen based on the weight they will have to support, which determines the overhang and thickness of the shelf.

How to Install a Floating Shelf – Useful to Know

Floating shelves for hidden installation come in different thicknesses and depths: if the plugs are not included in the package, you need to take these measurements into account and observe the diameter of the holes on the back to choose the right ones, sold in pairs. For a complete home improvement project, you may also want to consider updating your lighting or adding some wall decor to complement the new shelves.

Installation

Shelves 4-5 cm thick can adopt supports with a plate equipped with two protrusions, to be fixed to the wall with expansion plugs of small diameter: ideal for thin walls. Slide the metal support out of the shelf and place it against the wall to mark, with a grease pencil, the exact points where to drill the holes. A spirit level helps with alignment. When drilling holes in the wall, it is good that the drill has the accessory for dust extraction. The hole must be a couple of millimeters deeper than the length of the plug. Usually, nylon plugs are also included in the package. The side fins block their rotation during screwing, and the collar keeps the plug flush, preventing it from penetrating the masonry. Once the last plug is inserted, place the support and start fixing it with a couple of screws, one at the top on one side and one at the bottom on the other, without tightening fully: this frees your hands to insert the others. The shelf is simply inserted onto the supports and pushed against the wall: the thickness of the support disappears inside a recess on the back of the shelf. To stabilize it, you can also add some wall decor or a small mirror above the shelf for a polished look.

Hidden Plugs

Hidden plugs are a great solution for a clean, minimalist look. They are available in various sizes and materials, and they can support different weights depending on the wall type. For heavier shelves, consider using metal supports or reinforced plugs. If you're planning to style your shelf with books or decorative items, you might also want to browse bookcases and shelving units for additional storage options. For a cohesive room design, matching your shelf with a nightstand or dresser can create a unified look.

Frequently Asked Questions

• What tools do I need to install a floating shelf? You'll need a drill, spirit level, screwdriver, measuring tape, pencil, and appropriate wall plugs and screws. A stud finder is also helpful for drywall installations.
• How much weight can a floating shelf hold? It depends on the wall material and the type of support used. For lightweight items, standard plugs work fine; for heavier loads, use metal supports or anchor into wall studs.
• Can I install a floating shelf on drywall? Yes, but you must use appropriate drywall anchors or locate the studs for secure mounting. Avoid relying solely on drywall for heavy shelves.
• How do I ensure the shelf is level? Use a spirit level during marking and installation. Check both horizontally and vertically before securing the supports.
• What if my wall is tile or brick? Use a masonry drill bit and appropriate wall plugs designed for hard surfaces. A hammer drill may be necessary for brick or concrete.
