The most common material used at the bottom of a fire pit is sand. It’s also the most affordable alternative. Almost any form of sand will work well as a bottom material for a fire pit. 

Sand is simple to use, takes little upkeep, and prevents the fire from spreading. Sand also absorbs the heat from the fire, protecting everything underneath it from harm. 

The nicest part about using sand for a fire pit is that it lasts a very long time. The sand will last for decades and will keep your campfire looking excellent.



In many respects, dirt is comparable to sand, making it an excellent option for the bottom of a firepit. The biggest benefit of picking dirt is that it can be found almost everywhere. This is the kind of campfire we have at home.

With soil, the only difference is that some of the organic materials will burn. This may ultimately deteriorate and may need to be changed on a regular basis. 


A safe choice for the bottom of a fire pit is a bed of stones. Stones are also quite simple to get by. You will have the ideal bottom of the fire pit to utilize if you can discover stones that are tiny enough to produce a stable fire bed. 

Stones have the added benefit of providing an extra layer of protection for the ground under the fire pit. For example, placing stones on top of soil or sand might provide an extra layer of protection. At the bottom of a fire pit, stones may also be extremely attractive. 


Gravel is made up of tiny, shredded rocks that may be easily spread out across a large area. Gravel is an excellent choice for a fire pit’s bottom. It is similar to stones in that it has no drawbacks. It keeps the pit warm while also preventing the foundation from burning. 

Some varieties of gravel are very attractive and might even enhance the appearance of your fire pit. Gravel is a simple material to work with and maintain. Gravel is compatible with sand and soil, so you may combine the two for a more effective fire foundation.

Lava Flows are specifically made for use as fire retardants. However, they still work great at keeping the area heated.
