A crooked shelf is one of the most noticeable small flaws in any room, and it is also one of the easiest to avoid. The video above shows the process in action, and this guide walks you through the exact steps so you get it right the first time. It is written for homes, holiday rentals, offices, and hotels across Greece, where shelves often go up on solid concrete or brick rather than hollow drywall.
Know your wall before you drill
Most walls in Greek homes and hotels are concrete (beton) or hollow brick (tougla) with a plaster finish, not the hollow plasterboard common in northern Europe. That changes everything: you almost always need a masonry drill bit and plastic wall plugs (oupes) rather than simple drywall anchors.
Tap the wall and listen. A solid, dull sound means concrete or brick, so plan for a hammer drill and the right plug. A hollow echo means plasterboard, where you must either hit a stud or use a proper cavity anchor rated for the shelf's weight.
Match the fixing to the load
A few light books or a decorative vase is very different from a row of hardback files in an office or a heavy mirror in a rental bathroom. Choose plugs and screws sized for the bracket holes and the expected weight, and use at least two fixing points per bracket where the bracket allows it.
When in doubt, go up one size and add a fixing. Over-specifying the anchor costs a couple of euros; a shelf that tears out of the wall can damage the wall, the contents, and in a rental, your reputation.
Five steps to a straight shelf
- 1
Mark the height and find your reference line
Decide the shelf height and make a light pencil mark at one end. Measuring up from the floor is unreliable because floors are rarely perfectly level, so treat this first mark only as a starting point and let the spirit level set the true line in the next step.
- 2
Draw a level line across the wall
Hold a spirit level (or a level app on your phone for a quick check) against the wall at your mark and adjust until the bubble sits dead centre. Draw a faint pencil line the full width of the shelf. This single level line, not the floor or ceiling, is what makes the shelf look straight.
- 3
Mark the drill holes
Position the bracket or shelf hardware on the level line and mark each screw hole through the bracket with your pencil. For two separate brackets, measure the spacing carefully and confirm both sets of marks sit exactly on the same level line so the shelf will not tilt.
- 4
Drill and insert the wall plugs
Fit a masonry bit matched to your wall plug size and drill straight into the wall at each mark, keeping the drill horizontal. Blow out the dust, push a plastic plug into each hole until it sits flush, then you are ready to fix the bracket.
- 5
Fix the brackets and check before loading
Screw the brackets firmly into the plugs, set the shelf on top, and lay the spirit level along the shelf surface to confirm it reads level. Make any small adjustment now, secure the shelf to the brackets if your design requires it, then add your items, heaviest near the supports.

FAQ
- Do I really need a spirit level, or can I eyeball it?
- Use a level. The human eye is easily fooled, especially when ceilings or floors are slightly out of true, which is common in older Greek buildings. A basic spirit level or a phone level app takes seconds and is the single biggest factor in a shelf looking straight.
- What if my wall is concrete or solid brick?
- That is the norm in most Greek homes and hotels. Use a hammer drill with a masonry bit and insert plastic wall plugs (oupes) sized to your screws. Avoid lightweight drywall anchors on solid walls, as they are designed for hollow plasterboard and will not grip properly.
- How much weight can the shelf hold?
- It depends on the bracket, the screws, and above all the wall fixing. On solid concrete or brick with correctly sized plugs and two fixings per bracket, a well-mounted shelf easily holds books or kitchenware. For heavy loads or hollow walls, choose anchors rated for the weight and add extra fixing points.
