Can Limestone Be Used For A Fire Pit?

Having a firepit for your home can be a great way to extend your outdoor living space and create a cozy atmosphere for entertaining family and friends. But can limestone be used for a fire pit? Let's take a look to see if this is an option.

Due to maintaining a moderate temperature, natural limestone is a great choice for a fire pit. In addition, limestone has a smooth and silky surface that gives a stunning look. However, it is important to note that limestone should not be used for wood-burning fire pits, as high temperatures can cause it to explode.

Before choosing any rock for your fire pit, it's important to know its fire-resistance rating. In this article, we will discuss the pros and cons of using limestone in a fire pit. In addition, we will answer other frequently asked questions about fire pits, so read on!

Is Limestone A Good Choice For A Fire Pit?

When making a fire pit for a home, safety is important. Limestone is a safer option than other materials due to its thermal resistance, which keeps it from heating up quickly when exposed to flames.

However, limestone is still a porous rock that can explode if it reaches a high enough temperature. This means that it should not be used for wood-burning fire pits but instead for gas or propane-based ones. As long as you use the right fuel source, limestone can make for a durable and attractive fire pit.

Limestone is also an affordable material and doesn't require any special tools or skills to install. It's easy to cut into different shapes and sizes, making it perfect for customizing your fire pit design. Plus, its unique texture will give your fire pit a unique look.

You can find limestone at many home improvement stores, making it easy to find. You can either make your own or buy a pre-made limestone fire pit and have it installed.

If you want a matching look throughout your backyard, you can use limestone for other outdoor features. This can include pavers, planters, and benches. Limestone is durable and low maintenance, so you won't have to worry about it fading or cracking over time.

Overall, limestone is an attractive and durable option if used correctly. As long as you use the right fuel source and keep your fire pit away from high temperatures, limestone can be a great choice for your fire pit.

What Is The Most Affordable Stone For A Fire Pit?

If you are on a budget but want to create an attractive fire pit, gravel or crushed stone is the most affordable option.

Gravel and crushed stone are widely available and don't require any special tools or skills to install. It is important to note that these materials are not as durable as other stones, like limestone, and may be more prone to cracking or fading over time.

Other than stones, you can also use bricks as an affordable fire pit material. Bricks are a good option if you want to create a more traditional look and feel for your outdoor area.

Bricks are easy to install and are very durable, so they won't need much maintenance over time. Plus, they come in many colors, so you can choose the one that will best match your outdoor design.

You can also paint your bricks to match any color scheme you have in mind. They are also heat resistant, so they won't be affected by high temperatures like other materials can.

Lastly, cinder blocks are an affordable and heat-resistant option for a fire pit. Like brick, cinder blocks are easy to install, come in many colors, and can be used with wood or gas fuel sources.

Overall, you have plenty of options when it comes to choosing the most affordable stone for your fire pit.

Can You Just Dig A Hole For A Fire Pit?

For those who don't care about looks, you can just dig a hole in the ground and use it as your fire pit. However, this is not an ideal solution if you want to keep your fire pit safe and secure.

The soil around the hole can be easily disturbed by people or animals, which can cause your fire to spread quickly and uncontrollably. If you do choose this route, you should still line the hole with stones or bricks to keep your fire contained.

If you are looking for a more permanent solution, it is best to build a structure like a fire pit ring around the hole. This will help ensure that your fire stays where it's supposed to and won't spread as easily.

What Stones Should You Never Use For A Fire Pit?

There are some stones that you should avoid for a fire pit. Rocks that are very porous—in other words, contain water or air pockets trapped inside—can easily fracture when exposed to high temperatures and should never be used.

Let's take a look at them below:


Formed from hot volcanic lava, pumice is very porous and can easily fracture when exposed to fires. It is light and can hold water and air inside its structures, which can cause it to explode and send pieces flying in all directions.


Shale is a fragile material that can break into pieces when exposed to high temperatures. It is soft and doesn't have a lot of structural integrity, so it's not suitable for fire pits.


Sandstone contains a lot of air pockets and isn't strong enough to withstand extreme temperatures. It will crack and break easily and should never be used for a wood-burning fire pit.

River Rocks

You may have guessed, but river rocks contain a lot of trapped water, which can cause them to combust and explode when exposed to fires.

Pea Gravel

Pea gravel is a tiny stone, so they are not strong enough to withstand intense heat. Not only can they not hold heat, but they can also pop when exposed to fire.


Another volcanic rock, basalt is too brittle to be used for fire pits and can easily break when exposed to heat. It also can contain water and air, so it could be dangerous to use for a fire pit.


A beautiful but weak stone, soapstone is too fragile to withstand extreme temperatures. It can crack and break easily, so it isn't suitable for a fire pit.

Does A Fire Pit Need A Liner?

It's always a good idea to have a liner for your fire pit. A liner helps protect the material around it from extreme temperatures and can prevent it from cracking or breaking due to heat exposure.

It is especially important to have a liner if you are using a stone that isn't as durable or heat resistant, like gravel, crushed stone, shale, sandstone, or pea gravel.

A metal fire pit is usually pre-lined, so you won't need to use an additional liner. But if you are using a stone fire pit, it's best to get one that comes with a liner or purchase the right type of liner separately.

Why Do You Put Sand In The Bottom Of A Fire Pit?

It's common to put sand in the bottom of a fire pit for several reasons. Sand is an insulator, so it can help absorb and distribute heat evenly throughout the fire pit.

It also helps protect the material underneath from direct heat exposure, preventing cracks or breaks due to extreme temperatures.

Finally, sand helps create a more even surface and fills in any uneven cracks or crevices that may be present in the fire pit material. This can help reduce the risk of sparks flying out and also create a more comfortable seating area around your fire pit.

How Much Does A Stone Fire Pit Cost?

Depending on the type of stone and how big the fire pit is, the cost of a stone fire pit can range from around $200 to over $3,000.

It's also important to factor in other costs like the liner, sand, and any labor needed for installation. The overall cost of a stone fire pit can vary depending on all these factors and the materials used.

If you have the time and know-how, you can build your own stone fire pit for much cheaper. But make sure to use the right materials and keep safety in mind when doing so.

In today's world, many online resources make creating your own stone fire pit easy and cost-effective. With some research and creative planning, you can build a beautiful and safe stone fire pit in no time!
