The industry standard for durability is 1.25 inches (3 cm) . Thinner slabs may require additional support and are more prone to breaking.

Never buy based on small samples alone; natural variations in veining and color can vary drastically within a single lot.

Ask these questions at the showroom or stone yard to ensure you are getting a high-quality product that fits your space:

Higher-grade slabs have more consistent coloring and fewer structural defects, while lower-grade "commercial" granite may be more porous and fragile.

Fissures are natural cracks that can sometimes weaken the structure. Ask how these will be addressed during fabrication to ensure structural integrity.

Lighter granites are generally more porous and may need sealing more frequently (e.g., annually) than denser, darker varieties. Fabrication & Installation Questions
