Nothing brings people together quite like a fire pit — especially one you can build yourself with just a few affordable materials. Cinder blocks are a budget-friendly and versatile option for creating a cozy backyard fire feature. Whether you’re after rustic charm or modern simplicity, here are 15 outstanding cinder block fire pit design ideas to transform your outdoor space.
1. Classic Square Fire Pit
Simple, clean, and timeless. A square layout of cinder blocks stacked two or three levels high creates a safe and effective fire pit in no time.
2. Circular Cinder Block Pit
Go for a rounded design by slightly angling the blocks to form a circle. Add gravel inside and around the base for a polished look.
3. Cinder Block Bench Fire Pit
Surround your fire pit with built-in bench seating made from cinder blocks and wooden planks for the perfect chill zone.
4. Sunken Fire Pit
Dig the pit slightly below ground level and line the walls with cinder blocks for a sleek, integrated effect.
5. Fire Pit with Grill Grate
Turn your fire pit into a dual-purpose cooker by adding a metal grate on top — perfect for BBQ nights with friends.
6. U-Shaped Lounge Fire Pit
Arrange cinder blocks in a U-shape to create a seating nook around the fire, ideal for late-night conversations and marshmallow roasting.
7. Two-Tiered Fire Pit
Stack your blocks in two layers — one larger and one smaller on top — to give the pit visual depth and added wind protection.
8. Painted Block Fire Pit
Use heat-resistant spray paint to give your blocks a modern black or bold color finish that pops in your yard.
9. Raised Patio Fire Pit
Build the fire pit on a patio of gravel or pavers, with the blocks raised slightly for a structured, elevated feel.
10. Corner Fire Pit
Tight on space? Tuck a square fire pit into the corner of your yard or patio for a cozy, space-saving solution.
11. Cinder Block Fire Pit Table
Add a wide top layer of concrete slabs or tiles to create a table-like ledge around your fire pit — perfect for holding drinks and snacks.
12. Rustic Garden Pit
Leave the blocks unfinished and surround your fire pit with stones, logs, and plants for a naturally rustic vibe.
13. Mini Portable Fire Pit
Use just a few cinder blocks and a metal bowl or insert for a small, movable fire pit ideal for tiny patios.
14. Windshield Fire Pit
Stack the blocks higher on one side to act as a windbreaker — great for breezy areas and directing smoke away from guests.
15. Cinder Block Lounge Zone
Create a full outdoor living space with a fire pit in the center, cinder block planters on the sides, and cozy seating all around.
