Sintered Stone vs Large-Format Porcelain: What Changes

Both come from pressed powder and a hot kiln, so buyers treat them as one product. The firing recipe and the format range are different, and those differences decide which one belongs on a wall, a floor or a countertop.

Full-height sintered stone wall with continuous veining

Firing and format

Sintered stone is pressed and fired to reach near-zero porosity in slabs up to 1600x3200. Large-format porcelain stays in tile sizes up to 600x1200 with a glazed or matt body. The slab exists for continuity, the tile exists for handling and cost.

Put slabs where joints would interrupt the design: full-height walls, islands, reception desks. Put large porcelain where many hands install and replace: retail floors, corridors, bathrooms.

Installation and cost

A 1200x2700 slab needs trained fabricators, suction frames and a cutting plan. A 600x1200 tile needs a good tiler. Budget the install with the material, not after it. The slab guide and the tile TDS describe different trades.

Slabs for continuity, large porcelain for coverage. Match the trade to the format.
