Lava Rock Calculator

How Much Lava Rock Do I Need?

Most fire pits and fireplaces work well with 2 to 4 inches of glass depth. Preferences vary; some clients are content with 2 inches, while others prefer 4 inches. Generally, we use a 3-inch glass depth as our standard. Make sure all measurements are in inches.
