Creating an inground fire pit can be a wonderful addition to your outdoor space, offering both warmth and a visually appealing centerpiece for your backyard. If you’re looking for an enjoyable DIY project, an inground fire pit is an excellent option that can elevate the ambiance of your lawn or garden. Below, I’ll walk you through the basics of building your own inground fire pit, along with some considerations to keep in mind to ensure it’s safe, durable, and functional.
Steps to Build an Inground Fire Pit
Materials Needed:
- Fire pit ring (metal, stone, or brick)
- Shovel (for digging the hole)
- Gravel (for drainage)
- Sand (for leveling the base)
- Fire bricks or stone bricks (for lining the inside)
- Mortar or cement (to secure the bricks, optional)
- Optional decorative rocks or tiles (for the outer appearance)
Step 1: Choose the Location
First, decide on the best location for your inground fire pit. It’s important to pick a spot that:
- Is at least 10 feet away from any structures, trees, or bushes to reduce fire risks.
- Is on level ground to ensure the fire pit remains stable.
- Has good airflow to keep the fire burning well.
- Is easy to access and enjoy from your patio, garden, or seating area.
Step 2: Mark the Area
- Mark the perimeter of your fire pit with a stake and string or spray paint. You can make it any shape, but a circular fire pit is the most common and easiest to build.
- The diameter of the fire pit should be 3-4 feet for a moderate-sized fire.
Step 3: Dig the Hole
- Dig the hole to a depth of about 12-18 inches. The size depends on how deep you want the fire to sit. This will be the base of your fire pit, so dig it wide and deep enough to accommodate your fire pit ring and any additional layers of gravel or sand.
- Level the base of the hole, making sure it’s even so your fire pit sits securely.
Step 4: Add Gravel for Drainage
- Pour a layer of gravel about 3-4 inches deep at the bottom of the pit. Gravel will help with drainage, ensuring water doesn’t collect and cause rust or damage over time. It also helps with airflow under the fire, which keeps the flames burning.
Step 5: Add Sand for Stability
- On top of the gravel, add a layer of sand about 2-3 inches deep. This helps level the surface and gives you a smooth base for placing your fire pit ring or lining it with bricks.
Step 6: Install the Fire Pit Ring
- Place your fire pit ring (a metal fire ring or bricks) inside the hole. The fire pit ring helps contain the fire and keep it from spreading, ensuring safety.
- If you’re using bricks, you can stack them around the edge of the hole. You can secure them with mortar or leave them dry-stacked, depending on your preference. Mortar will create a stronger, more permanent structure, but a dry-stack can allow for easier future repairs or adjustments.
Step 7: Line the Inside with Fire Bricks
- If you’re using fire bricks or stone bricks, you can line the inner walls of your pit to create a heat-resistant boundary for your fire. These bricks will absorb and reflect heat, making the fire more efficient and preventing damage to the surrounding area.
- Ensure the fire bricks are placed snugly against each other, and if using mortar, make sure it’s evenly applied.
Step 8: Finish the Outer Appearance
- You can decorate the outside of your fire pit with stones, bricks, or tiles. This adds a stylish touch to the pit and helps it blend into your backyard landscape.
- If desired, you can also add a stone seating area or bench around the fire pit to create a cozy gathering space.
Step 9: Add More Gravel or Decorative Stones
- You may want to add a final layer of decorative stones or gravel around the perimeter of the fire pit for an extra aesthetic touch.
Step 10: Safety Check
- Make sure everything is level, secure, and that no materials are too close to the flame. If using a metal fire ring, ensure it’s high enough above the ground to prevent heat transfer.
Safety Considerations
- Fire Safety: Always ensure that the fire pit is located away from any flammable materials, such as furniture, trees, and overhanging branches.
- Fire Pit Cover: Consider purchasing a fire pit cover to protect your fire pit when it’s not in use. This keeps debris out and prevents rust from forming on metal surfaces.
- Supervision: Never leave a fire unattended, especially in an inground fire pit. Keep a bucket of water, fire extinguisher, or a garden hose nearby just in case.
Building an inground fire pit is a rewarding DIY project that enhances your outdoor space with both beauty and functionality. Whether you’re hosting summer BBQs, enjoying cozy nights with friends and family, or simply gazing at the dancing flames, your inground fire pit will provide a perfect focal point. With the right materials, a little creativity, and careful attention to detail, you’ll have an impressive and safe fire pit that will bring warmth and charm to your backyard for years to come!
