Can You Use Cinder Blocks to Make a Fire Pit?

Yes, cinder blocks can be used to make a fire pit. The main difference between cinder blocks and concrete is that cinder blocks are made of small pieces of coal that have been treated to protect them from fire. Cinderblocks will not ignite if they come in contact with an open flame, so they are ideal for use in fireplace pits or other outdoor fires.

The benefits of using cinder blocks for fire pits include their fire resistance and the fact that they are much easier to work with than concrete. When making a fire pit out of cinderblocks, it is important to place them in a sheltered area so that they do not get too hot or too close to the flame.

Determining the amount of cinder blocks needed

Once you’ve determined the size of your cinder block fire pit, it’s time to determine how many blocks will be needed. Typically, a cinder block fire pit will be 24″ wide by 36″ long sides. A good height for a fire pit wall is between 12″ to 14″ inches.

After you have selected your cinder blocks, it should be a simple task to divide your wall lengths by your block size.

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

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

There are many different places to build your cinder block fire pit, depending on what you want it for. If you want a small fire pit that can be easily built in a few minutes, go with a cinder block range or fireplace. If you want a larger, more complicated fire pit, choose one with more pieces and create the design yourself.

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

One of the biggest deciding factors when it comes to a cinder block fire pit is whether you want it to be permanent or temporary. Permanent cinder-block fire pits are the most common, and they can take up very little space. They’re also easy to build, but they do require some additional materials and time. Temporary cinder block fire pits, on the other hand, are more versatile and can last for a longer period of time. They’re also less expensive to build, but they may not be as popular because they don’t offer as many features.

Step 3: Add Finishing Touches to Your Cinder Block Fire Pit

If you’re looking to make your cinder block fire pit even more special, you can add finishing touches. You can choose to add a built-in grill, or you can get a charcoal grill that attaches to the top of your cinder block fire pit. Either way, it’ll give your guests a great experience while they cook their burgers or hot dogs.
