How does marble perform in humid climates compared to granite?

When choosing between marble and granite for humid climates, understanding their performance is crucial. Marble, a metamorphic rock, is known for its elegance and unique veining. However, it is more porous than granite, making it susceptible to moisture absorption. In humid environments, this can lead to staining, etching, and even mold growth if not properly sealed and maintained.

Granite, on the other hand, is an igneous rock with a denser structure, making it less porous and more resistant to moisture. This characteristic makes granite a better choice for humid climates, as it is less likely to absorb water or develop stains. Additionally, granite is highly durable and requires less frequent sealing compared to marble.

In summary, while marble offers unmatched beauty, granite outperforms in humid climates due to its superior moisture resistance and durability. Proper sealing and maintenance can extend the life of both stones, but granite remains the more practical option for areas with high humidity.
