The hallway is the hardest-working floor in any home, holiday rental, or hotel — it takes the most foot traffic and the most first impressions. The video above walks through a real hallway tiling job from start to finish; this guide breaks down each phase with the practical detail you need to plan your own project or brief a professional tiler in Greece. Whether you are renovating a Athens apartment, refreshing a Cyclades villa, or upgrading an Airbnb property, getting the subfloor right and the layout centred are the two decisions that make or break the result.
What makes a hallway different from other rooms
Hallways are long and narrow, which magnifies any tile that is even slightly off-square. A 2 mm drift on the first row becomes a 20 mm gap by the far wall. That is why experienced tilers always set out the layout dry — without adhesive — before mixing a single bucket of mortar. In Greek homes the hallway also often connects directly to the outdoors, meaning the subfloor sees moisture ingress from rain, sandy sandals, and cleaning water almost daily.
For rental properties or hotels the tile specification matters as much as the installation. Greek building regulations (ΕΑΚ / ΕΛΟΤ EN 14411) classify tiles by slip resistance; in entrance areas you should specify a tile with a wet R-value of R10 or higher. Porcelain (full-body or glazed) and natural stone such as marble or travertine are the most common choices in Greece, each requiring different adhesives and aftercare.
When to call a professional tiler
Floor tiling is a skilled trade and hallway tiling in particular rewards experience. If the existing floor is a suspended timber floor, a concrete screed less than 40 mm thick, or shows any signs of damp rising from below, a qualified builder or waterproofing specialist should assess it before any tiles go down. Structural changes — removing thresholds that form part of a load-bearing frame, or cutting into concrete slabs — always require a licensed engineer and, in many Greek municipalities, a building permit (οικοδομική άδεια).
A good rule of thumb: if you are comfortable with a grinder, spirit level, and tile cutter, a straightforward concrete-subfloor hallway under 15 m² is achievable as a confident DIY project. Anything with underfloor heating pipes, significant height-change transitions to adjacent rooms, or large-format tiles (60×60 cm and above) is better handed to a professional — misaligned large-format tiles are expensive to fix and difficult to hide.
How to tile a hallway floor: 5 key steps
- 1
Prepare and level the subfloor
Remove all existing floor coverings and adhesive residue. Check the concrete or screed with a long spirit level (2 m straightedge): any hollow more than 3 mm over 2 m must be filled with self-levelling compound before tiling. In Greece's climate, if there is no existing damp-proof membrane, apply a liquid waterproofing membrane (υδατοστεγανοποίηση) such as a cementitious slurry or polyurethane coating along the base of all walls. Allow full cure time as stated on the product — typically 24 hours — before proceeding.
- 2
Set out the tile layout
Find the centre of the hallway by snapping chalk lines from the midpoint of each wall. Place a dry row of tiles along the longest axis, including your chosen spacers (2–3 mm for porcelain, 3–5 mm for marble). Adjust the starting point so that cut tiles at both ends are equal and no cut piece is narrower than half a tile width. Mark your reference lines with a pencil or chalk; these lines guide the first adhesive rows and must not be disturbed during laying.

Apply adhesive and set the tiles
Mix a floor-grade tile adhesive (C2 class flexible cement adhesive for porcelain; white adhesive under light marble to prevent ghosting) to a smooth, lump-free paste. Use a notched trowel — 6 mm notches for tiles up to 30×30 cm, 10–12 mm for tiles 60×60 cm and above — and apply in one direction. Bed-butter large tiles on the back as well (back-buttering). Press each tile firmly with a slight twisting motion and check level constantly with a spirit level and rubber mallet. Work in 1 m² bays so the adhesive does not skin over before tiles are placed. Keep the expansion joints specified by the adhesive manufacturer (typically every 4–5 m² and at all room perimeters).
- 4
Cut border tiles and transitions
Measure each border cut individually rather than assuming the wall is straight — in older Greek buildings the walls are rarely perfectly parallel. A wet-blade tile cutter or angle grinder with a diamond blade gives a clean cut; wear eye protection and a dust mask. At doorways and transitions to other flooring surfaces, fit a metal or brass threshold strip to protect the tile edge and accommodate any height difference. In buildings with underfloor heating, leave the manufacturer-specified expansion gap around all fixed elements.
- 5
Grout, seal, and cure
Wait the full adhesive open time (usually 24 hours at 20°C, longer if the weather is cool or the subfloor is damp) before grouting. Choose an unsanded grout for joints under 3 mm and a sanded or epoxy grout for wider joints. Push grout diagonally across the joints with a rubber float, then wipe excess off with a barely-damp sponge in a circular motion. Allow the grout to haze, then polish with a dry cloth. Once fully cured (48–72 hours), apply a penetrating sealer to natural stone and unglazed tiles. Keep foot traffic off the floor for at least 24 hours and avoid wet mopping for 5–7 days.

FAQ
- What is the best tile size for a narrow hallway?
- For a typical Greek hallway of 90–120 cm width, 30×60 cm or 45×45 cm tiles laid on the diagonal visually widen the space while keeping the number of cuts manageable. Very large formats (60×120 cm) can work in wider entrances but demand a near-perfectly level subfloor and a skilled tiler to avoid lippage.
- Can I tile over existing floor tiles?
- Sometimes, but with caution. The existing tiles must be fully bonded (tap each one — a hollow sound means it has de-bonded and must come up), the floor height increase must be acceptable at doorways, and the combined weight must be within the structural floor loading. In Greece, older apartment blocks with solid concrete slabs can usually handle a tile-on-tile installation; suspended timber floors generally cannot. Check with a structural engineer if in doubt.
- How long does hallway floor tiling take?
- For a professional tiler, a straightforward 8–12 m² hallway with a concrete subfloor is typically a two-day job: half a day for prep and layout, one day for tiling, and the following morning for grouting once adhesive has cured. Add a day each for self-levelling compound and waterproofing if the subfloor needs it. DIY timelines are typically 2–3 times longer, so plan for a long weekend at minimum and arrange an alternative entrance route.
