There are first a few things you must do before you get started. First, you need to make sure you have all the tools and materials handy before you start working on your DIY fire pit. According to a number of estimates, these items should cost you no more than $200. Here are those materials:
• Gravel
• Sand
• 52 retaining wall blocks

Optional items include a steel ring to line the inside of the pit and a metal grate to cover the top of the pit once it is built.

Dig Your Hole

You will need to dig a hole approximately 2 feet wider than you want your fire pit to be which is about 4 feet across. Make the area as level as possible. You will need about 4 inches of gravel and 4 more inches of sand to help make sure that this area is completely level.

Lay the Blocks

Now it is time to assemble the stone layers. You can use a steel ring that holds it into place to make sure that all of the layers are round and the exact same size.

If you do not have a steel ring make sure the bottom layer is as perfectly round as possible, as the next few layers will lay on top of the base. The middle of the pit will typically be about 32 inches around.

…Stack More Stone

Continue laying the blocks in a circle until the DIY fire pit reaches your desired height. Depending on the size of your fire pit, it should take approximately 10-15 stones for each layer all the way around.

If you plan on cooking over the fire pit it probably will be a good idea to buy a metal grate to cover the fire pit, that way if someone accidentally drops a hot dog or marshmallow over the fire it can still be grabbed and eaten.

There are numerous other fire pit designs that are more complex and ornate that can be found for free online.
