Prefab sizes that skip the wait.

Standard counters at 112" × 26", island slabs at 108" × 42", and matching 6" backsplashes — all 2cm and laminated flat-edged. It's genuine natural stone, sized to land on a faster timeline than cutting custom.

Polished, honed, or leathered.

The same slab reads completely differently depending on its finish. Polished deepens color and movement, honed calms it into a matte, and leathered adds tactile grip that hides fingerprints and water spots on busy counters.
