How to Build A Surround for Outdoor Fire Pit Inserts

A fire pit is a great addition to any backyard. It not only provides warmth on chilly nights, but it also creates a cozy and inviting atmosphere for outdoor gatherings with friends and family. If you're considering an outdoor fire pit for your backyard, there's always the option to build a surrounding wall around it.

Where to Find Blocks for a Fire Pit Surround

First things first, you'll need to choose the blocks for your fire pit. Fire pit kits or retaining wall blocks can be found at any home improvement store or landscape supply store. These blocks are available in a variety of sizes, colors, and styles so that you can make your fire pit creation uniquely yours. Go in with an idea of what you want to make for your fire pit, and explore the different possibilities. 

How to Build A Surround for Your Outdoor Fire Pit

Retaining wall blocks are used to build the structure of the fire pit and to contain the fire. There are many different types of retaining wall blocks available, but not all of them are suitable for fire pits. We've come up with a few helpful tips to assist with the process of building a retaining wall around your fire pit:

Size of the Fire Pit

The first thing to consider when selecting retaining wall blocks for your fire pit is the size of the fire pit itself. The blocks should be large enough to provide adequate support for the fire pit, but not so large that they overpower the design. A common size for retaining wall blocks is 8"x8"x16", but smaller or larger blocks can also be used, depending on the design.

Load-Bearing Capacity

When selecting retaining wall blocks for your outdoor fire pit, it's important to choose blocks that have a high load-bearing capacity. This means that the blocks are strong enough to support the weight of the fire pit and the fire without cracking or collapsing.

Heat Resistance

Retaining wall blocks that will be used for a fire pit must be heat-resistant. Some materials, such as stone or firebrick, are naturally heat-resistant and make good choices for fire pit blocks. Others, like limestone or other soft stones that retain water, are not heat-resistant and should be avoided.


Retaining wall blocks come in a variety of styles and colors, so you can choose blocks that match the style and design of your backyard. Some popular options include stone, brick, and concrete blocks.


Finally, consider your budget when selecting retaining wall blocks for your fire pit. Some materials, like stone or brick, can be expensive, while others, like concrete, are more affordable.
