So, you’ve decided on a spot. Start with ensuring that you purchase fireproof cinder blocks.

If you are using old cinder blocks at your disposal, make sure they are porous and lightweight. Porous cinder blocks allow steam to vent; if the cinder blocks aren’t porous, they could potentially explode.

Next is to choose whether you’d prefer a temporary or permanent fire pit design. (More on this idea in a moment!)

Pros and Cons of Cinder Block Fire Pits

Like any other material, cinder blocks have pros and cons to consider when deciding whether you’re interested in a cinder block fire pit or not.



  • Inexpensive
  • Easy to work with
  • Widely available
  • Blocks are sizeable and, therefore, easy to assemble
  • Cinder blocks are not fire-rated (only fire-resistant).
  • Cinder blocks are not as aesthetical as other landscaping stones or bricks.
  • Building a neatly rounded fire pit can be somewhat challenging (although not impossible).
Building cinder block fire pits is also a ton of fun and a great way to express your creativity!

How to Make a Fire Pit From Cinder Blocks – Step by Step

Building your cinder block fire pit might lead to a quick trip to the store and some afternoon physical work. But, don’t fret! By the end of the week, you’ll be able to invite your friends over for a get-together around the new fireplace!

Purchase the following materials to make a cinder block fire pit:

  • Cinder blocks
  • Sand or gravel
  • Shovel
  • Rake

Step 1: Decide Where You Want To Build Your Cinder Block Fire Pit

cinder block fire pit front yard
Your front or backyard is the perfect place for your cinder block fire pit! But, make sure that you follow backyard fire tips from the EPA and ensure that it’s legal in your area.

The very first step is to learn if fire pits are legal in your community and if you need permits or inspections. If you’re not sure, take a trip down to your municipal office of local fire departments to find out these answers. Or, call them!

Then, before we can get started, decide where you’d like your fire pit and define its place. For example, some prefer a fire pit near the housegarden corners, or a focal point in the center of their patio area.

Consider the shape and size of the fire pit you’re envisioning and ensure the selected spot is at least 20 feet away from shrubs, trees, sheds, garages, or your home.

Also, look above the potential fireplace location and ensure that there aren’t any overhanging trees that can catch fire (sparks easily ignite dry foliage).

Step 2: Decide Whether You Want a Permanent or Temporary Cinder Block Fire Pit

cinder block pit fire cemented
If you decide upon a permanent fire pit location, it’s possible to seal parts of your fire pit using cement. However, I prefer to leave the cinder blocks uncemented to help increase circulation. It also lets me move the bricks if I decide to later!

temporary design is the simplest of the two. It will take approximately one hour to pack your cinder blocks in a ring (adjust each so that the corners of the blocks touch).

It’s best to remove around 4 to 6 inches of soil before arranging your cinder blocks. Ensure that the holes in the cinder blocks face skywards.

If you’d like, you can turn one cinder block every three feet to create a draw hole, allowing airflow.

If you prefer a permanent design, you’ll have to be slightly more patient and take on a couple of additional steps to ensure that the fire pit lasts long.

  • Dig out 4 to 6 inches of soil.
  • Fill the center of your new fire pit with sand or gravel (to prevent accidental fires).
  • Lay your first row of cinder blocks below the ground.
  • Add extra layers of cinder blocks until you reach your desired height.
  • Position your cinder blocks in a way that they straddle the seams between the cinder blocks in the row below.
  • Use mortar to seal the blocks together.
  • Allow the mortar to cure for about a week before using your fire pit.

If you’re still not sure about the best size for your cinder block fire pit, here’s my best tip!

“Keep It Simple” $60 Cinder Block Fire Pit

Here’s another budget-friendly cinder block fire pit to consider adding to your backyard. Keep It Simple Crafts showcases a wonderfully rounded fire pit tutorial that you’ll love!

In-Ground or Low-Profile Cinder Block Fire Pits

I love this simple cinder block pit fire! Perfect if you want a straightforward, low-profile backyard fire pit. You could get the same low-profile effect by burying larger cinder blocks halfway in the soil.

Building an in-ground cinder block fire pit may need more effort regarding digging into the soil to reach an appropriate depth. However, in-ground fire pits are great because the wind won’t easily sway the flames.

If you want to go the other way, consider a low-profile fire pit. Add one small (circular) layer of cinder blocks for a quick and effortless fire.

Multi-colored Cinder Block Fire Pit
