Stone Thickness Guide: What Architects Need to Know

From 14mm wall tiles to 100mm structural slabs — how to specify the right thickness for floors, walls, countertops, and facades.

Thickness Overview

Stone thickness directly impacts structural integrity, weight load, and installation method. Our range spans from 14mm (decorative wall tiles) to 100mm (structural elements and heavy-traffic commercial floors).

Floor Applications

For residential floors: 19-20mm is standard. This provides sufficient strength for normal foot traffic while keeping weight manageable. Commercial floors typically require 28-30mm for durability under rolling loads.

Wall Cladding

Wall cladding can use thinner material — 14-15mm for interior feature walls, 19-20mm for exterior facades. Mechanical fixing is required above 2m height regardless of thickness.

Countertops & Vanities

Countertops and vanity tops use 28-30mm for a substantial edge profile. For the popular 'raw edge' look, 30mm provides enough material for the irregular split-face edge detail.

Weight Calculations

Weight calculation: width(cm) × length(cm) / 10000 × thickness(cm) / 100 × 2700 kg/m³. Example: a 60x60cm tile at 2cm = 19.4 kg. This matters for structural engineering and shipping logistics.
