It’s been an outdoor-projects extravaganza around here lately! It started with the woodshop benches (here and here … sorta outside since it’s the garage), then the gas fire pit table, outdoor bench, this new backyard DIY fire pit, there’s a couple types of planters coming soon, aaaaand – if you follow along on Instagram, you’ve already heard – I’m tackling the most dreaded project EVER next week … stripping and refinishing the decks. But, for now, let’s just focus on the project at hand – this $50 DIY fire pit!
50 big ones.
I think the adhesive cost about $4 though … so 54 big ones … Not bad for a new fire pit!
You can buy full fire pit kits, but they generally cost quite a bit more. They include all the bricks and a heat insert. I did not put a heat insert in this DIY fire pit, but I’ve built a few fire pits just like this and never had an issue.
I didn’t have an exact plan when I went to Menards to get the supplies, so I spent some time stacking bricks (*read: I built about 6 different fire pits in the garden center and everyone thought I was crazy) until I figured out a pattern I liked. The fire pit is about 33″ x 33″ and 8″ tall. Adjust the number of bricks if you want bigger or smaller (I wouldn’t recommend going any smaller though).
Tools & Supplies:
- 8 | 6″ x 6″ Paver Blocks
- 24 | 6″ x 9″ Paver Blocks
- 52 | 3″ x 6″ Paver Blocks
- 4 Tubes of Landscape Adhesive
- Caulk Gun
- Tape Measure
** Adjust the supplies as necessary to build a fire pit that fits your space.
Measure out the fire pit area and remove any grass or vegetation. Use a tape measure to mark the area and dig down about 1″-2″ all the way around the border. Place the first level of pavers around the border to make sure they all fit. Expand and adjust the border as necessary. Once the pavers fit nicely in the border, remove the pavers and dig the rest of the fire pit area out until it’s level.
A lot of people dig out about 6″ for the fire pit area and fill it with gravel. Gravel helps with drainage and maintaining a level surface. I skipped the gravel with our fire pit and built it directly on the dirt. It burns just fine, but feel free to add gravel if you want.
If you build directly on the dirt, make sure to pack the dirt down really well so it doesn’t move around and settle after you build the fire pit. I dug the fire pit area out and then dropped the biggest paver blocks all around it a few times to compact everything … very scientific, I know. The thing hasn’t moved at all, so it seems to have worked!
Once you have a solid, level surface for your fire pit, lay out the first level of pavers.
Remove the pavers one by one to add landscape ahesive between them. Work your way around the first level until all the pavers are stuck together.
This landscape adhesive works wonderfully. I used the same stuff on the top of the gas fire pit table. It’s super strong and sets quickly.
Repeat for the second level of pavers.
Leave two small pavers out of the second level to allow air flow to the fire (you can see the missing blocks in the above photo).
Use the adhesive between all the pavers on the second level, as well as on the top and bottom of first and second levels so the levels stick together.
Repeat for the third level of pavers.
Leave out two small bricks on the opposite sides as you did in Step 3 to allow airflow.
Repeat for the top (fourth) level of bricks.
Do not leave out any bricks on the top level so there’s a nice, complete top surface.
And there you have it – brand new fire pit for $50!
Though it’s not as “refined” as an official fire pit kit, I’m really happy with how ours turned out. It looks so much better than what we had before (a small metal one) and burns great. We haven’t had any issues with bricks moving or settling weirdly.
Please let me know if you have any questions and I’ll get back to you as soon as possible!
