Large-format sintered stone and porcelain look great on worktops, walls and floors, but cutting them is a different game from ordinary tiles. The hard, edge-brittle material chips and cracks easily if the blade is fed wrong. We cut sintered stone and porcelain to size and cut openings in worktops — precisely, wet and at your place in Warsaw, without hauling heavy slabs back and forth.

How we cut sintered stone and porcelain, step by step
- We check the slab, mark the cut lines and protect the surface with tape.
- We lay the slab on a flat bench supported along its full length.
- We cut wet with a diamond blade on a guide rail — slowly, without pressure.
- We chamfer and sand the edges so they are smooth and safe.
- We clean up the slurry, check the dimensions and leave it tidy.
Cut-outs in worktops for sinks, taps and hobs
We most often cut openings for undermount sinks, taps, soap dispensers and induction hobs. Round holes are cut with a diamond hole saw; rectangular hob cut-outs with a guided grinder, with rounded corners (sharp corners crack sintered stone). All on site, so the finished worktop never has to go to a workshop.
Common mistakes when cutting sintered stone
- Dry-cutting with a standard blade — overheating and micro-cracks.
- Sharp cut-out corners instead of rounded ones — a crack starting point.
- No support along the full length of the slab — it cracks under its own weight.
- Feeding too fast and pressing — chipping at the edge.
Checklist before cutting
- You know the exact final dimensions and slab thickness.
- There is access to water and power.
- There is space to lay out and support the slab.
- You know where the sink and hob openings should go.
A Warsaw example
In Mokotów a client bought a 6 mm sintered-stone kitchen worktop and needed it fitted to the units, with cut-outs for an undermount sink and an induction hob. We trimmed the slab to size, made both cut-outs with rounded corners and chamfered the edges — in under three hours, with no chipping and no dust in the flat.
Frequently asked questions
How is cutting sintered stone different from regular tiles?
Sintered stone and large-format porcelain are harder and more brittle at the edge. We cut them wet, with a water-cooled diamond blade on a guide rail, to avoid chipping and cracks. A standard tile cutter is not enough here.
Can you cut an undermount sink hole in a finished countertop?
Yes. We cut openings for sinks, taps or soap dispensers with a diamond hole saw and a guided grinder, then chamfer the edges. We do it on site so the heavy slab does not have to travel.
Do you bring your own tools?
We arrive with a full kit — diamond blades, hole saws, guide rails, a vacuum and water cooling. We only need access to water and power and space to lay the slab out.
Is the cutting dusty?
We work wet and with extraction, so dust is minimal. Afterwards we clean up the slurry and leave the place tidy.
What formats and thicknesses do you cut?
Typically sintered stone 3–12 mm and large-format porcelain up to 120×280 cm. Thicker composite worktops are quoted individually.
How long does a countertop with cut-outs take?
A simple trim takes tens of minutes; a kitchen worktop with sink and hob cut-outs usually 2–3 hours. Usually same day or next day.
Which districts of Warsaw do you cover?
All of Warsaw and the surrounding area — Mokotów, Wola, Śródmieście, Ursynów, Praga, Bielany. We also travel to towns near Warsaw.
