American Fire Products Extra Large Gray Lava Stones (4" - 6") - LAVAST-XL
Make a bold impression with our Extra Large Gray Tumbled Lava Stone. Ranging from 4" to 6" in size, these oversized stones are naturally volcanic and tumbled to a smooth, modern finish. Their dramatic scale adds visual weight and sculptural beauty to large fire pits, fireplaces, and commercial fire features—perfect for designers seeking a standout top layer.
Due to their size, these stones must be installed above a base layer of Small Lava Rock or Medium Lava Rock to ensure proper burner coverage and heat flow. Once layered, they deliver clean flame movement, enhanced depth, and a premium architectural finish.
Oversized Beauty, Engineered to Perform
Each batch is sorted and tumbled for consistency in size and tone. The soft gray-to-charcoal colors highlight the brilliance of the flames while blending beautifully with both modern and rustic outdoor settings. Their porous structure promotes airflow while resisting cracking, melting, or fading under intense heat.
Striking Finish, Lasting Durability
These extra large lava stones are clean-burning, low maintenance, and built to last. Simply apply 2–4 inches above your base layer to enjoy their bold texture and dependable heat performance season after season.
If you're looking for fire media that makes a strong visual impact while enhancing flame performance, Extra Large Gray Tumbled Lava Stone is the ideal top-layer solution.
