Expert DIY Guide: Build a Durable Fieldstone and Sand Fire Pit in Your Backyard

Step 1

Evaluate the Site

Head to your backyard at sunset and envision cozy evenings by a crackling fire. Identify a level 16- to 20-foot diameter circle, clear of bushes, shrubs, overhanging branches, playgrounds, and high-traffic areas. Ensure easy access, privacy from neighbors or roads, nearby firewood storage, and a hose for safety.

Step 2

Source Your Materials

If driveway space is tight, order 3/8-inch crusher run (gray stone) from a local sand and gravel supplier, clearing room for delivery. Aim for a 2- to 4-inch thick base. A wheelbarrow is essential for transport. A full 18-ton load covers about 500 square feet at 4 inches deep.

Visit landscape supply yards for fieldstones: 16- to 20-inch stones for the inner fire ring and 8- to 12-inch ones for the perimeter. Delivery on pallets is common for a fee—prepare space. Grab mortar cement, silica sand (for bright white) or playground sand (light brown, budget-friendly), and sandbags from your hardware store.

Step 3

Lay the Gravel Base

Stake a screwdriver or grade stake at the center. Tie on nylon string, measure your radius (8-10 feet for the full circle), and mark the perimeter while stretching the string. Use this as a guide to dump and rake gravel inside, achieving a smooth, level 2- to 3-inch layer of crusher run.

Pro Tip

Enlist a helper—family or neighbors who'll enjoy the fire pit make great raking partners.

Construct the Inner Fire Ring

With the center stake in place, measure a smaller radius (about 3 feet) and dig a shallow trench. Mix cement-sand mortar per package instructions. Fill the trench base, set 16- to 20-inch stones, and continue layering mortar and stones. Use the string to check alignment; tuck smaller stones in gaps.

Step 5

Fill the Inner Ring with Sand

Wheel in silica or playground sand, filling to about 4 inches deep without disturbing the set stones.

Step 6

Build the Outer Perimeter Ring

Dig a trench for the outer circle and mortar in 8- to 12-inch stones for a finished border.

Step 7

Fill the Perimeter Ring with Sand

Add 4 inches of sand to the outer ring. Rake level, using a trowel to pack into crevices and edges without shifting stones.

Step 8

Finish Your Fire Pit

Surround the outer edge with hardwood mulch to conceal excess gravel and create a polished border. Add Adirondack or beach chairs for ultimate fireside comfort.
