Gas Fire Pit Rocks and Stones

Lava rock, fire glass, ceramic stones, and purpose-made fire pit pebbles are all safe options. These materials are heat-treated or naturally porous enough to withstand high temperatures without cracking or releasing moisture explosively. Avoid sandstone, river rock, or any stone with trapped moisture, as these can fracture under heat and pose a safety hazard.

The amount needed depends on the diameter and depth of your fire pit bowl. As a general rule, a 3–4 inch layer of lava rock or fire glass is sufficient to cover the burner and create an even flame display. Measure your pit's interior dimensions and consult with our sales team for a precise quantity estimate based on your specific unit.
