Surfaces
Large-format porcelain
Thin, hard and heat-proof, porcelain slabs go where stone cannot: outdoor kitchens, fireplace faces, full walls. Mitered edges make 12mm read as a solid block.

The material
Thin, hard and heat-proof.
Large-format porcelain slabs are fired from refined clays and minerals at over 1,200°C into a dense sheet 6 to 12mm thick and up to 126 by 63 inches. It is practically impervious, and it is the surface for the places stone and quartz cannot go.
- Best for
- Outdoor kitchens and grills, fireplace faces, shower walls and floors, full wall cladding, and countertops where a thin profile matters. Mitered edges make a 12mm slab read as a solid block.
- Durability
- Extremely hard and scratch-resistant, with colour-fast pigments that do not fade in sunlight. Thin slabs need careful handling in fabrication, which is why we run them on dedicated CNC programmes.
- Heat & stains
- Fully heat-proof: hot pans, direct flame and freeze-thaw cycles leave no trace. Near-zero water absorption means it does not stain and resists mould in wet areas.
- Maintenance
- The lowest of any surface. Warm water and a mild cleaner, no sealing and no special products. It is chemical-resistant, so common household cleaners are fine.
- Look
- Printed and glazed finishes reproduce marble, stone, concrete and metal with high fidelity, in polished, matte and textured surfaces. Book-matched patterns are available in most collections. The pattern sits on the surface, so exposed cut edges show the body.

Good to know
Porcelain, answered
Yes, especially if you want a thin profile, a surface that takes direct heat, or a countertop that continues outdoors. Large-format porcelain is fired at over 1,200°C, has near-zero water absorption, does not need sealing and keeps its colour in sunlight. It is available 6mm and 12mm thick in slabs up to 126 by 63 inches.
There are three to know. First, the pattern sits on the surface, so a cut edge shows the body of the slab; that is why we usually mitre porcelain edges so the pattern wraps and the top looks solid. Second, a chip is harder to repair invisibly than in natural stone or quartz. Third, thin slabs need careful handling, which is why we run porcelain on dedicated CNC programmes.
Yes. Porcelain is one of our first recommendations for wet areas and full-slab shower walls, because it has near-zero water absorption and the large format means few joints and no grout lines to clean. See bathroom projects
Choose porcelain for heat, sunlight, outdoor kitchens, fireplace faces and very thin profiles. Choose quartz for a consistent pattern and a thicker edge without mitring. Both are non-porous and never need sealing. If you are undecided, we can show both side by side in the showroom. Book a consultation
