Sized just right the gray Westville fire pit is a wonderful companion for your outdoor seating. The 19.5-inch square column is made of GFRC (Glass Fiber Reinforced Concreate) for durability. Reflective fire glass, included, adds an eye catching touch. This fire pit accommodates a standard propane tank with 32,000 BTU (not included) and is activated with a push-button igniter. An included lid can protect your fire pit when not in use.
