When purchasing or building a backyard fire pit, the first thing to go through is the manufacturer’s instructions.

Sand is the most common and most versatile material you can use at the bottom of your fire pit. It is cheap, easy to install, and provides great heat absorption.

Dirt is another material you can use at the bottom of a fire pit. It is also available everywhere. It is easy to use, heat-resistant, and free. You can dig dirt in your backyard and put it at the bottom of the pit. Though dirt is convenient, it features less heat resistance than sand.
