Pavers also work well, but since these are literally made to be used as a wall, they stack nicely. The fire pit is 36″ in diameter, so its circumference is about 113″. Each block is about 9″ long on the short end, so I needed 13 bricks for each “level”. I decided on two levels, so this is 26 blocks total.
How many blocks do I need for a fire pit?
Calculate how many stones or blocks you will need by multiplying the diameter of the circle by 3.14 (pi). For example, for a 4-foot diameter circle, multiply 48 inches by 3.14 for a total of 150.72 inches.
How many bricks do I need for a 36 fire pit?
You’ll need 80 bricks for a 3-ft (36″ inch) diameter fire pit.
How many concrete blocks do I need for a fire pit?

How many paver blocks do I need for a fire pit?
A circular fire pit measuring 37inches in diameter takes 12 pavers of 12 inches for each ring. For three layers of paver rings a total of 36 pavers with a perfect fit can be supplied with instructions and support for building the fire pit.
Will cinder blocks explode in a fire pit?
Cinder blocks generally do not explode in a fire pit. But you need to ensure that you aren’t using compressed concrete blocks. Instead, your cinder blocks should be porous enough to vent steam. If your cinder blocks aren’t porous enough, the build-up of steam can cause an explosion.
What do you put in the bottom of a wood burning fire pit?
What do you put in the bottom of a fire pit? You’ll want to start with a layer of sand at the bottom of the pit, and then top the sand with gravel, lava rocks, fire pit glass, paving stones or even bricks for your fire pit. Alternatively, you can simply use dirt.
Are pavers safe for fire pit?
These bricks are typically fired to 1800ºF and easily withstand the heat of flames. Landscaping brick that’s been kiln-fired is safe to use. Brick paver stones should also be safe to use. A three-foot-wide diameter works well for a temporary brick fire pit.
How big should a circle be for a fire pit?
The optimal size for a fire pit is between 36 and 44 inches inside diameter. That will create enough room for a healthy fire but still keep gatherers close enough to chat.
Can you use retaining wall block for fire pit?
Your fire pit will be just fine with retaining wall blocks, but once you’re done building the pit, you may wish to insert a steel fire ring. Doing so will extend the life of your blocks by preventing them from drying out prematurely.
Can I build my own outdoor fireplace?
There are a lot of advantages to building an outdoor fireplace yourself. Primarily, you can spend a lot less money on it than if you had one built for you. You can also be in charge of the design. If you don’t like something, you can change it up so it fits you and your family’s needs.
Are concrete blocks good for a fire pit?
You can build a cinder block fire pit directly on the ground. You don’t want to use a compressed concrete block that’s too dense in a fire pit. It must be porous enough to vent any steam that forms inside as trapped water turns to steam. If blocks aren’t porous, they could explode as steam builds.
Is concrete block fireproof?
Concrete block can withstand high temperatures and water pressure from fire hoses better than other materials deemed fire resistant such as fiber-reinforced gypsum panels.
How many stones do I need for a 36 inch fire pit?
Pavers also work well, but since these are literally made to be used as a wall, they stack nicely. The fire pit is 36″ in diameter, so its circumference is about 113″.

How deep should a fire pit be?

You can go deeper if you want, but keep in mind that you don’t want the hole so deep you can’t enjoy watching the fire.
How many bricks does it take to build an outdoor fireplace?
