What are the best stone types for outdoor seating in areas with high humidity?

When selecting stone for outdoor seating in high humidity areas, durability and resistance to moisture are key. Here are the best stone types to consider:

1. Granite: Highly resistant to moisture, scratches, and heat, making it ideal for humid climates. Its dense structure prevents water absorption.

2. Bluestone: A type of sandstone, bluestone is naturally slip-resistant and handles humidity well, perfect for patios and benches.

3. Slate: Known for its low porosity, slate resists water damage and retains its appearance even in damp conditions.

4. Basalt: Durable and non-porous, basalt withstands humidity and extreme weather, offering a sleek, modern look.

5. Limestone: While slightly porous, sealed limestone performs well in humidity and adds a classic, elegant touch.

For longevity, choose stones with low porosity and consider sealing them periodically to enhance moisture resistance. These options ensure your outdoor seating remains beautiful and functional for years.
