What thickness of granite is recommended for heavy-duty outdoor bar stools?

When selecting granite for heavy-duty outdoor bar stools, thickness plays a crucial role in ensuring durability and stability. The recommended thickness for such applications typically ranges between 1.25 to 1.5 inches (3.2 to 3.8 cm). This thickness provides sufficient strength to withstand frequent use and exposure to outdoor elements like rain, wind, and temperature fluctuations.

Thinner granite slabs (under 1 inch) may crack or chip under heavy weight or impact, while thicker options (over 1.5 inches) can be unnecessarily heavy and costly. For commercial or high-traffic outdoor settings, opting for 1.5-inch granite ensures longevity and resistance to wear.

Additionally, consider the granite’s finish—a honed or flamed surface offers better slip resistance compared to polished finishes. Pairing the right thickness with proper sealing will enhance the stool’s weather resistance and lifespan. Always consult with a stone supplier to verify the granite’s density and suitability for outdoor use.
