Can You Use Cinder Blocks to Make a Fire Pit?
Cinder block is an inexpensive building material great for fire pits. You can quickly build permanent or temporary cinder block fire pits and in any style you prefer.
A cinder block fire pit will effortlessly transform your summer garden into a majestic hangout – or hideaway! A fireplace also creates a warm, welcoming, and relaxing atmosphere that will relieve your stress after a long day.
However, when choosing your perfect outdoor fireplace, the options are endless, and choosing your ideal style becomes an arduous task! Perhaps, this is why many homesteaders are turning to the most straightforward, budget-friendly, DIY cinder block pit ideas.
When searching for fire bricks, make sure the brand you're seeking says for fire pits! That's why these fire bricks from Rutland are my top choice for all outdoor ovens, fire pits, stoves, and more.
I've noticed that the cost of DIY fireplace supplies has increased over the last year due to inflation. However, I think that these Rutland bricks are still of excellent value - you can build (or repair) your existing fire pit without breaking the bank. Superb and versatile bricks!
These bricks can be used to build a new fireplace, fire pit, or anywhere where you need a brick that can withstand high temperatures. These bricks are rated up to 2700 degrees Fahrenheit and there are 6 bricks in a box.
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.
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
Step 1: Decide Where You Want To Build Your Cinder Block Fire Pit
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 house, garden 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
A 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!
A three-foot-diameter circle comfortably accommodates three to four people. Add an extra foot for each additional person!
Step 3: Add Finishing Touches to Your Cinder Block Fire Pit
When finishing up your cinder block fire pit, consider that the fire pit's heat may negatively impact some surfaces!
That's one reason I'm a big fan of these fire pit heat shields. They're perfect for protecting surfaces and property against heat damage - especially if you love to keep your fire pit burning as much as I do - nearly nonstop!
They protect up to 1,300 degrees Fahrenheit. The mat also absorbs up to 90% of the fire's heat and will remain close to body temperature. Perfect!
Consider finishing your cinder block fire pit off with a coping of flat finish of concrete blocks or use bricks, tiles, and pretty stones to achieve an attractive finish.
Add a grill and bring those outdoor benches closer- you’re ready to enjoy your backyard fire pit!
