Large Format Tile Countertop in Warsaw
15.03.2026Large Format Tile Countertop in Warsaw
A large format porcelain countertop is an alternative to stone and quartz that costs less, handles heat and scratches, and looks like natural marble or concrete. Laminam, Neolith and Dekton slabs 6-12 mm thick are bonded to a plywood or chipboard substrate to create a seamless monolithic surface. Used in kitchens, bathrooms and bar areas. We make large format countertops across Warsaw — from Mokotow to Bialoleka.
How much does it cost and what affects the price
The cost depends on countertop size, slab type (6 mm or 12 mm porcelain, sintered stone), number of cut-outs (sink, hob, sockets) and edge treatment. A simple straight countertop is cheaper. L-shaped, with an island or complex cut-outs — more expensive. The substrate (plywood/chipboard) is a separate item. Materials are charged separately. Current prices are in the table below.

| Sintered stone / slab / 6–12 mm | 300 zł/m² | 450 zł/m² |
| Large format 120+ cm | 220 zł/m² | 350 zł/m² |
| Large format precision cut | 60 zł/mb | 100 zł/mb |

How the work is done on site
- Measurement and template. We measure the kitchen or bathroom and create a template from card or MDF. Sink, hob, socket and joint positions are determined.
- Substrate preparation. An 18 mm plywood or moisture-resistant chipboard base is fitted to the cabinets — flat and rigid.
- Slab cutting. The porcelain is cut on a professional bridge saw with a diamond blade and water cooling. Sink and hob cut-outs are made with a diamond router.
- Bonding. The slab is glued to the substrate with flexible adhesive (Mapei Keraflex Maxi S1). Dual application is mandatory.
- Edge treatment. Edges are covered with a strip of the same slab, mitred at 45 degrees or butt-jointed. Sanded and polished.
- Grouting and sealing. The wall joint is sealed with sanitary silicone. L-joint between countertop sections — colour-matched epoxy adhesive, virtually invisible.
- Sink installation. Undermount sink — the cut-out is sanded perfectly smooth and sealed with silicone.
Common mistakes with tile countertops
- Weak substrate — the countertop flexes and the slab cracks. Minimum 18 mm plywood, rigidly attached.
- Voids under the slab — unfilled areas crack under load.
- Freehand angle-grinder cuts — uneven edges and visible chips. Only a professional saw.
- Unfinished edges — raw plywood and slab edge visible. Edges must be clad in matching material.
- Rigid adhesive — the slab cracks from thermal movement. Flexible adhesive is essential.
- Unsealed sink cut-out — water reaches the plywood, which swells and rots.
What to prepare before the technician arrives
- Kitchen units or bathroom furniture installed and levelled.
- Slab purchased with surplus: Laminam, Neolith, Dekton or large format porcelain. Thickness 6-12 mm.
- 18 mm plywood or moisture-resistant chipboard.
- Flexible adhesive.
- Sanitary silicone.
- Decide the sink type (undermount or drop-in).
- Sink and tap — buy in advance for precise measurement.
- Confirm socket and hob positions — cut-outs must be known before cutting.
- Power and water nearby.
- Clear the work area.
A real case from Warsaw
A kitchen in Mokotow, L-shaped countertop 3.2 m² — the client chose Laminam Fokos Roccia 12 mm, grey stone effect. Measured, MDF template made, cut on a bridge saw. Substrate — 18 mm plywood on IKEA Metod units. Slab bonded with Mapei Keraflex Maxi S1, dual application. Undermount Blanco sink cut-out with a diamond router, edge sanded smooth. Edges — strips of the same Laminam, mitred at 45 degrees. L-joint filled with colour-matched epoxy — the seam is virtually invisible. Two days of work. The countertop looks like a solid stone slab at a fraction of the cost.
Frequently asked questions
How is a tile countertop better than stone?
Cheaper than natural stone and quartz, lighter (6-12 mm vs 20-30 mm), does not absorb water, withstands heat up to 300 C, and offers a huge range of designs.
What slab thickness is best?
For a kitchen — 12 mm (stronger, more substantial look). For a bathroom — 6 mm is sufficient. With an edge strip it looks like 20-30 mm.
Can you put a hot pan on it?
Yes. Porcelain handles up to 300 C. But extreme thermal shock could theoretically cause a micro-crack — a trivet is recommended.
Does it scratch?
Porcelain is harder than most countertop materials. A regular knife will not scratch it, but use a chopping board as good practice.
How is the sink cut-out made?
With a diamond router and water cooling. The edge is sanded perfectly smooth.
Are joints visible on an L-shaped countertop?
With correct work — virtually no. The joint is filled with colour-matched epoxy adhesive, under 1 mm wide.
Which slab brands do you recommend?
Laminam (Italy), Neolith (Spain), Dekton (Cosentino) are top tier. Budget options from Tubadzin and Paradyz in large format.
How long does fabrication take?
A straight countertop — 1-2 days. L-shaped with cut-outs — 2-3 days. Plus a day for adhesive cure.
Are materials included?
No. Slab, plywood, adhesive and silicone are purchased by the client. Labour includes consumables and cutting.
Can it be used in a bathroom?
Yes. Porcelain does not absorb water and is ideal for bathroom countertops — around basins and bathtubs.
