Whether you are refitting a kitchen in a mainland apartment, a Cycladic holiday rental, or an Athenian family home, a well-fitted worktop transforms the entire workspace. The video above walks through the core process; the guide below breaks it into clear, ordered steps you can follow or use to brief a skilled joiner. For most laminate and solid-wood worktops the work is within reach of a competent DIYer, but stone, ceramic, and quartz surfaces — and anything touching a gas hob — should always involve a licensed professional.
Choosing the Right Worktop Material
Laminate worktops are the most affordable and forgiving material to cut and join on site — a good choice for rental properties where durability matters more than prestige. Solid oak and beech look premium and can be sanded back repeatedly, but they must be oiled regularly to resist moisture, which matters in the Greek climate. Quartz and granite offer the best heat and scratch resistance for busy kitchens or hotel prep areas, but they arrive pre-cut from a specialist workshop and are installed by the supplier — you do not cut these on site.
Worktop thickness in Greece typically follows the EU standard of 38 mm for laminate and 40 mm for stone. Check that your base units are built to accept whichever thickness you choose before ordering, as mixing depths mid-project creates levelling headaches.
Tools, Materials, and Safety Checks
You will need a jigsaw with a fine-tooth downcut blade (to avoid chipping the surface laminate), a circular saw or track saw for long rip cuts, a router with a straight bit for sink cut-outs, worktop joining bolts (also called worktop connectors or draw bolts), silicone sealant rated for kitchen use, and a good-quality worktop jig if you are cutting a mitred corner joint. A spirit level, pencil, steel tape, and clamps complete the kit.
Before you begin, turn off the water supply at the stop valve and cap or remove any existing plumbing connections. If the kitchen has a gas hob, do not disconnect or reconnect the gas line yourself — in Greece this work must be carried out by a licensed gas technician (technitis aerion) registered with the relevant professional body. Electrical supply to hob cut-out areas should also be isolated at the consumer unit.
How to Fit a Kitchen Worktop: 5 Steps
- 1
Measure and mark the worktop
Hold or place the worktop slab loosely across the base units with the front overhang (usually 20 mm) sitting proud of the cabinet doors. Use a scribing block — a small offcut set to the gap between wall and worktop back edge — to transfer the wall's irregularities onto the worktop surface in pencil. This scribing line is your cut line; following it ensures the back edge beds flush against even a bowed or tiled wall. Mark any cut-outs for hobs or sinks at this stage using the template provided by the appliance manufacturer.

Cut to length and shape
Secure the worktop face-down on a stable surface and cut along your scribed line with a jigsaw fitted with a fine downcut blade; cutting from the underside prevents chipping on the visible laminate face. For a mitred corner joint (where two worktop sections meet at 90°), use a purpose-made worktop jig to router both pieces to exactly 45°. Work slowly and keep the saw plate flat against the board throughout — a lifted sole plate will give you an angled edge that will not joint cleanly. Cut hob and sink apertures by drilling a starter hole inside the waste area first, then following the template line with a jigsaw.
- 3
Drill for joining bolts and dry-fit
With both pieces of a corner joint face-down and pulled tight together, mark the positions for the joining bolts — typically two or three per joint, spaced evenly. Use a flat-bottomed (Forstner) bit to drill the recesses so the bolt bodies sit below the surface; a regular twist bit will crack the board. Slot in the connectors and draw the joint finger-tight, then flip the whole assembly right-side up and sit it on the cabinets. Check for level along the full run with a spirit level and shim the base units if needed — the worktop should show zero twist before you glue anything.
- 4
Bond and seal
Once the dry-fit is confirmed, apply a thin, continuous bead of kitchen-grade silicone along the top rail of each base unit and along both faces of the mitre joint. Pull the joint tight with the joining bolts, wipe away squeeze-out immediately with a damp cloth, then press the worktop down onto the unit rails. Fix the worktop from underneath by driving screws up through the cabinet corner blocks into the worktop — do not drive screws down through the surface. Seal the back edge and any wall junctions with a matching colour silicone bead and smooth it with a wetted finger or a caulking tool.

Fit the sink and reconnect services
Drop the sink into its cut-out from above (for undermount sinks the sequence is reversed — bond the sink rim before fitting the worktop, which is easier with a professional's help). Clip or bolt the sink basket and waste fitting into place, then reconnect the trap, supply hoses, and tap tails. Turn the stop valve on slowly and check every connection for drips before restoring power to the dishwasher or any under-counter appliance. If you have a gas hob, call your registered gas technician to reconnect the supply line and test for leaks before use.

FAQ
- Do I need a building permit to replace a kitchen worktop in Greece?
- Replacing a worktop like-for-like is classed as routine maintenance and does not require a building permit (oikodomiki adeia) in Greece. A permit is only needed when you alter load-bearing structures, change room layouts, or add new plumbing stacks. However, any gas work must be signed off by a licensed technician regardless of permit status.
- Can I cut a quartz or granite worktop myself?
- No. Stone worktops are templated and cut using diamond-tipped wet saws in a workshop. Attempting to cut quartz or granite on site with standard woodworking tools will crack the slab, void any warranty, and create hazardous silica dust. Always have stone surfaces cut and installed by the supplier's own team.
- How do I stop the joint between two worktop sections going black with mould?
- The joint faces must be fully coated with PVA glue or a dedicated worktop-joint compound before the joining bolts are tightened — silicone alone is not enough for a mitre joint. Once fitted, reseal the top seam with a continuous bead of anti-mould kitchen silicone and replace it every three to five years. Keeping the joint dry by wiping up spills promptly is the single most effective long-term measure.
