Silestone and Dekton come from the same company (Cosentino) but behave — and price — differently. Here's the honest comparison, using our own published slab prices.
The numbers
- Silestone (quartz): about $35/sq ft for entry colors in 3 cm, up to about $73/sq ft for Eternal Calacatta Gold. 2 cm runs roughly 15–25% less than 3 cm.
- Dekton (sintered ultracompact): about $27/sq ft for entry colors in 1.2 cm, to about $54/sq ft for the premium veined colors in 2 cm. Thin 8 mm sheets for cladding cost less still.
When Silestone wins
Quartz is the kitchen default for a reason: warm to the touch, huge color range, forgiving to fabricate (which keeps fab quotes lower), and the marble-look colors are excellent. If your project is a standard indoor kitchen, Silestone usually delivers more look per dollar.
When Dekton wins
Dekton is essentially stone forged in a hot press — UV-stable, scorch-proof, freeze-proof. It's the one you can use outdoors, behind a cooktop as a full panel, or even as a fireplace surround. You pay a bit more in fabrication (it demands experienced installers), but the material itself is competitively priced — our entry Dekton is actually cheaper per square foot than entry Silestone.
Thickness strategy
Dekton's 1.2 cm with a built-up edge reads like a 3 cm top for less money and weight; Silestone's 3 cm gives you the classic solid-slab edge with no lamination line. Ask for both numbers — on our site, every slab shows per-thickness pricing chips right on the product page.
