Sheet vinyl is one of the most practical flooring choices for Greek homes, holiday rentals, and hotel bathrooms — it is fully waterproof, easy to clean, and available in patterns that closely mimic stone or tile at a fraction of the cost. The video above walks through the installation process visually, while this guide breaks down each stage so you can prepare materials, avoid common mistakes, and decide confidently whether the job suits a competent DIYer or warrants a professional fitter. No building permit is required for a standard sheet vinyl installation on an existing subfloor, though addressing damp or structural subfloor damage beforehand may require licensed trades.
Why Sheet Vinyl Works Well in Mediterranean Properties
Sheet vinyl comes in rolls typically 3 m or 4 m wide, which means you can often cover a bathroom or kitchen with a single cut and no seams — a major advantage in wet rooms where seams admit moisture. Modern products carry a wear layer of 0.2–0.55 mm that resists summer sand, holiday footfall, and cleaning chemicals far better than older linoleum.
In a Greek coastal property, where humidity swings between seasons and tiled subfloors are common, sheet vinyl also tolerates slight floor movement better than rigid click planks. It is not a substitute for proper damp-proofing: if you see rising damp or persistent moisture coming up through a concrete slab, that must be treated by a qualified damp-proofing specialist before any new floor goes down.
Subfloor Requirements Before You Start
Sheet vinyl is unforgiving of an uneven base — any bump or hollow telegraphs through the relatively thin material and eventually causes premature wear. The subfloor must be dry, structurally sound, and flat to within 3 mm over a 1.8 m span. On concrete slabs, use a self-levelling compound to fill low spots; on timber subfloors, screw down any loose boards and fill gaps with flexible floor-levelling compound.
Remove all skirting boards, door thresholds, and old adhesive residue. If the existing floor is old vinyl and firmly bonded, you can often lay over it after light sanding, but a floor with multiple old layers should be stripped back completely. Any structural subfloor rot or significant concrete deterioration is a job for a licensed contractor before you proceed.
How to Lay Sheet Vinyl Flooring
- 1
Measure the room and cut a template
Measure the length and width of the room at their widest points, then add 100 mm on every edge to allow for trimming. For irregular rooms — common in older Greek properties — cut a paper or cardboard template on-site rather than relying on measurements alone. Transfer your template lines onto the vinyl roll, marking the face side to avoid confusion. Always account for pattern repeats: most decorative vinyl has a repeat of 150–600 mm, so buy enough to align the pattern from the entrance of the room.
- 2
Unroll and acclimatise the vinyl
Unroll the sheet in the room or an adjoining space and leave it for at least 24 hours at room temperature, ideally above 18 °C. Sheet vinyl softens slightly with warmth and becomes far easier to cut and fit without cracking. In Greek properties that have been closed over winter, heat the room first — cold vinyl is brittle and will split along a scribed cut.

Rough-cut, position, and scribe the edges
Carry the rough-cut sheet into the room, butt one long straight edge against the most prominent wall, and let the excess lap up all other walls. Using a scribing tool or a block of wood, trace the exact wall profile onto the vinyl — this transfers every bump and angle precisely. Cut along the scribed line with a sharp hook-blade knife and a straight metal rule; a dull blade tears rather than cuts. Work from the longest wall towards the most complex angles (alcoves, door frames, toilet bases). At door frames, undercut the architrave so the vinyl slides underneath for a neat finish.

Adhere or loose-lay the sheet
For rooms under about 12 m², loose-laying with perimeter double-sided tape is common and gives a removable floor — useful in rental properties. For larger rooms, full-spread flooring adhesive (applied with a notched trowel) or pressure-sensitive adhesive is recommended to prevent the sheet from shifting over time. In wet rooms such as bathrooms, always fully bond the perimeter strip — at least 200 mm in from each wall — and seal around the bath, toilet base, and shower tray with a waterproof silicone sealant once the floor is down. Let the adhesive reach its open time (check the product datasheet — typically 15–30 minutes) before laying the vinyl into it.

Trim, re-fit skirting, and seal
Once the vinyl is bonded and pressed down with a floor roller or rolling pin, use a trimming knife to cut the final edge flush against the wall. Re-fit skirting boards over the edge — do not pin through the vinyl itself, as this restricts movement and can cause buckling. Fit transition strips at doorways where the vinyl meets another floor covering. Finally, run a bead of silicone sealant at every junction with sanitary ware, and at the junction between the wall and floor if the room has no skirting. Allow at least 24 hours before heavy foot traffic and 48 hours before wet mopping.

FAQ
- Can I lay sheet vinyl directly over existing ceramic tiles?
- Yes, provided the tiles are all firmly bonded, have no sharp raised edges, and the total floor height increase is acceptable for door clearance. Fill grout lines with a flexible floor leveller, allow it to cure fully, and sand flush before laying. Loose or hollow tiles must be re-bonded or removed first, as they will eventually crack under the vinyl and create bumps.
- How do I cut neatly around a toilet base or pedestal basin?
- Make a series of short relief cuts from the edge of the vinyl in towards the obstacle, fold the sheet up tight against the base, and scribe the profile onto the vinyl with a compass or scribing block. Cut along the line with a sharp knife, then test-fit and trim as needed. For a truly watertight result, finish with a bead of clear silicone sealant around the entire base after the floor is glued down.
- Does sheet vinyl flooring need a building permit in Greece?
- No. Replacing a finished floor covering is classified as minor interior maintenance and does not require a building permit (οικοδομική άδεια) under Greek law. However, if the work involves opening the subfloor, moving drains, or addressing damp that requires structural intervention, those related works may trigger permit requirements. When in doubt, consult a licensed civil engineer (πολιτικός μηχανικός) or your local planning authority.
