About porcelain slab / sintered stone
Sintered porcelain slabs are fired at extremely high temperature, producing a surface that is non-porous, UV-stable, heat-proof, and remarkably thin — often 6 to 12 mm.
The low weight is a real advantage in walk-up buildings and on cabinetry that can't carry a 3 cm stone slab.
Specifier's tips
- Requires a fabricator experienced with thin slab — chipping risk during cutting
- Mitred edges are standard to create a thicker apparent profile
- Ideal outdoors and on sunny terraces where quartz would fade
Frequently asked
Is porcelain slab fragile?
Once installed on a proper substrate it's extremely durable. The vulnerability is during transport and fabrication.
Can it be used as flooring too?
Yes — matching floors, counters, and wall cladding is one of its strengths.
