Hanging kitchen wall units looks straightforward but the margin for error is small — a cabinet loaded with dishes weighs 30–50 kg, so the fixings and the wall behind them must be up to the job. The video above walks through the full process with a professional carpenter; this guide breaks it into clear steps with the extra details that matter in Greek homes, holiday rentals, and hotels where walls are typically hollow brick (τουβλάκι), aerated concrete block (ytong), or traditional stone. Read the steps before you pick up a drill, and you will save yourself a re-hang.
What the wall is made of changes everything
Greek residential construction almost universally uses hollow ceramic brick or aerated concrete block rather than timber-framed stud walls. Neither material holds a standard wood screw reliably under sustained load. You need the correct anchor for your substrate: chemical resin anchors (χημικές βύσματα) or heavy-duty nylon frame plugs rated for the shear force — not the cheap universal plugs sold in packs of 100. Before buying anything, probe one spot with a bradawl to confirm the wall type, then buy anchors rated for at least 1.5 times the expected cabinet load per fixing point.
If you live in a building with a Greek engineering certificate (μελέτη), load-bearing walls (φέρων οργανισμός) are identified in the drawings. You should not chase deep into those walls without consulting a structural engineer. Kitchen wall units generally mount on internal partition walls, which is fine — just confirm before drilling.
Planning the layout before you drill
Mark out every cabinet position on the wall in pencil before picking up a drill. Kitchen wall units in Greece are typically hung 50–55 cm above the worktop, leaving clearance for splashback tiles and appliances. Use a long spirit level or a laser level to draw a continuous horizontal line across the full run — this is your reference line, not the ceiling, which is rarely truly level in older Greek buildings.
Also plan around services. Electricity conduits (μπουζί) run vertically or horizontally inside the wall in fixed corridors per Greek electrical standards. If you are unsure where they run, use a wall scanner (detector) before drilling any fixing hole deeper than 30 mm. Gas pipes and water supply pipes are a harder stop — if your kitchen has either running inside the wall zone where cabinets will hang, get a licensed plumber or gas engineer to confirm safe zones. Do not guess.
How to hang kitchen wall units: 5 steps
- 1
Mark the height line and stud or solid-anchor positions
Draw a level horizontal line on the wall at the height where the bottom of the cabinets will sit. On hollow-brick or ytong walls, mark fixing points every 40–50 cm along the line, choosing positions where the drill meets solid material (avoid the hollow channels in ceramic brick — probe first). On solid reinforced concrete columns or beams, any position works with the correct concrete anchor. Two fixings per cabinet is a minimum; three or four is better for units wider than 60 cm or intended to hold heavy items.
- 2
Drill and set the wall anchors
Use a hammer drill with the correct bit diameter for your chosen anchor — the anchor packaging specifies this. For aerated concrete (ytong), use a standard drill without hammer mode, as hammer action breaks the cell structure and weakens the grip. Blow dust out of each hole and insert the anchor flush with the wall surface. For chemical resin anchors, inject the resin, insert the threaded rod, and wait the full cure time stated on the cartridge (typically 20–45 minutes at 20 °C) before applying any load.
- 3
Attach the hanging rail or back-plate to the cabinet
Most flat-pack kitchen wall units use an adjustable metal hanging rail system (sometimes called a suspension rail or mounting plate). Fix this rail to the back panel of the cabinet inside the unit according to the manufacturer's instructions — usually two screws per bracket hooked over the rail. Check that the brackets are positioned so the cabinet will hang at the correct depth from the wall. If your cabinets use a direct-screw-through-back-panel method instead, pre-drill clearance holes at the correct centres to match your wall anchors.
- 4
Lift the cabinet onto the wall and make initial adjustments
Hanging wall units is a two-person job — one person holds the cabinet while the other hooks or screws it into position. Hook the cabinet brackets over the wall rail or drive the first two screws loosely through the back panel into the anchors. Do not fully tighten yet. Check level front-to-back and side-to-side with a spirit level. Most rail systems allow fine height and tilt adjustment via a screw on the bracket; use this now. Once the cabinet is level and at the correct height, tighten all fixings fully, working from the top screws down.
- 5
Hang adjacent units and fit doors and shelves
Hang the next cabinet in the run the same way, then clamp the two units together at the front stile with the connector bolts provided (usually M6 or M8 screws tightened from inside). This distributes load across the run and keeps faces perfectly flush. Once all units are hung and connected, recheck the level across the full run with a long straight-edge. Fit hinges and doors last — adjust the hinge screws (three-way adjustment on Euro hinges) so every door hangs parallel with a consistent 2 mm gap. Fit shelves and check the load before signing off.

FAQ
- Do I need a building permit to hang kitchen wall units in Greece?
- No permit is required for hanging wall cabinets in an existing kitchen — this is a minor interior fit-out task. A permit (οικοδομική άδεια) would only be required if you are making structural changes, moving walls, or altering drainage. If your kitchen renovation involves moving gas or water supply points, those trades require licensed professionals (certified plumber, gas engineer) but not a separate building permit for the cabinet hanging itself.
- What anchors should I use in Greek hollow brick walls?
- The most reliable choice for hollow ceramic brick is a toggle or butterfly anchor (νύχι) for lighter cabinets, or a chemical resin anchor (χημική βύσμα) with a perforated sleeve for heavily loaded units. Avoid standard expansion plugs in hollow brick — they grip only the face shell, which can crack under load. For ytong (aerated concrete), use anchors specifically rated for porous substrates; the packaging will state this clearly. Always check the rated shear load is at least 50% above your expected cabinet weight.
- How high above the worktop should kitchen wall units be hung?
- The standard in Greece, as across Europe, is 50–55 cm between the worktop surface and the bottom of the wall unit. This gives clearance for standard under-cabinet appliances and a comfortable working height. In holiday rentals or hotel kitchenettes where users of varying heights are expected, 55 cm is the safer choice. If you are tiling the splashback first, complete and grout the tiles before hanging the cabinets so you can get the tile spacing right without the cabinets in the way.
