DIY Patio Upgrades: Building a Fire Pit

July 11, 2025


Looking to transform your backyard into the ultimate gathering spot? A DIY fire pit is one of the best ways to upgrade your outdoor space, and it’s a project most homeowners can tackle in a weekend. Not only does a fire pit add charm and warmth, but it also becomes a focal point for relaxing evenings, s’mores with the family, or entertaining friends. With some thoughtful planning and the right materials, you can create a fire pit that’s both safe and stylish.

Why Build a Fire Pit?

A fire pit offers more than just a place to build a fire—it enhances your outdoor living space with:

  • Cozy warmth for cool nights
  • A fun spot to roast marshmallows or hot dogs
  • Natural, rustic ambiance
  • An affordable and attractive backyard feature that adds lasting value

Best of all, you don’t need to be a contractor to build one. Let’s walk through the steps.

Step 1: Choose the Right Location

Start by selecting a level area in your yard or patio that’s at least 10 feet away from any buildings, fences, trees, or overhangs. Safety is key. Clear away any grass, roots, or debris to create a clean workspace.

Step 2: Gather Tools and Materials

Before you dig, make sure you’ve got everything you need:

  • Shovel
  • Steel rake
  • Tape measure
  • Level
  • Rubber mallet
  • Gravel (3” deep base)
  • Sand
  • Fire pit blocks or retaining wall blocks
  • Fire ring insert (recommended for longevity)
  • Construction adhesive (high-temperature rated)

Find these materials and more at your nearest Tennessee Ace Hardware location or at tennesseeace.com.

Step 3: Prep the Ground

Use a stake and string to trace a circle between 36–44 inches in diameter. Mark the outline with spray paint or chalk. Then:

  1. Dig down 6–8 inches.
  2. Fill the base with about 3 inches of gravel and compact it.
  3. Add a 1-inch layer of sand and level it.

This foundation helps with drainage and stability.

Step 4: Stack the Fire Pit Blocks

Place your first ring of fire pit blocks directly onto the leveled base. Use your level and rubber mallet to ensure each block sits evenly. Once satisfied with placement:

  • Dry-stack the first layer
  • Apply construction adhesive to the second and third layers for stability
  • Insert your metal fire ring (if using) and adjust block placement as needed

Step 5: Add the Finishing Touches

Let the adhesive cure per the manufacturer’s instructions. Then, fill the bottom of the fire pit with a thin layer of gravel or lava rock to assist with drainage and heat distribution.

Safety Tips

  • Never use river rocks—they can explode under heat.
  • Keep a bucket of water or fire extinguisher nearby.
  • Never leave a fire unattended.
  • Check your local fire codes before starting construction.

Bonus Upgrades

Want to take your fire pit to the next level? Consider:

  • Adding a grill grate for open-fire cooking
  • Surrounding the pit with pavers, gravel, or flagstone for a built-in seating area
  • Installing solar-powered LED lights around the perimeter for ambiance and safety

Wrap-Up

With just a few tools, some durable materials, and a little effort, you can build a fire pit that becomes the heart of your backyard. Whether you’re roasting marshmallows or enjoying quiet nights by the fire, it’s a project that delivers warmth and memories.
