How to Build a Patio Firepit

This ain’t any old patio fire pit. This addition to our backyard cost $125 AND only took 30 minutes to put together. Not even kidding.

So we finally got our stamped concrete patio finished this past Friday. Can I just say… I’m in love! I really wanted a corner fire pit but wasn’t quite sure if we could really pull it off. Then when we were at Ace Hardware this past week we noticed a little fire pit on display made from retaining wall rocks.

To get started we chose the Living Accents 35 inch round fire pit. You want to make sure the bowl you choose has the big lip around the edge. Do NOT assemble when you get it home. Yeah, that’s the best part.

Totally not needed; just a little something to add character. Now you can make the fire pit as high as you want, but we decided to only do three rows.

Well since we don’t need those, just grab a screwdriver and remove the brackets. This will help the bowl fit flush with your top layer of stones.

And then we sat back and admired our work…

Fire pit cost us $125: $80 for the insert and $45 rocks (3 layers of 15 rocks) at $1 a piece. And the fire pit only took us 30 minutes to build. We got home from work at 6:15 on Friday and were done by 6:45. Then watching the Blues get whooped by the Blackhawks by 7pm.

No joke.

I’m pretty sure I’ve got the chocolate. I always have chocolate.

        One concern…unless you plan on cleaning it after every use, the lye that is a result from the creation of ashes will be washed out by the rain and cause major problems for your concrete and stamped decoration. Just a suggestion – disassemble and move to a leveled area off the deck. Its a little more trouble but if you built a form out of 2x4s the size of the perimeter of the pit and just dump in some bags of Sacrete, rake it level and wet it down with a hose your pit (you don’t even have to throughly mix it) will always be level.

        That said, this is a great idea. Thanks for sharing.

    Erin…..I love it!! I will pass on the marshmallows but maybe you would have a Hebrew National Hot dog for me? Actually, I will bring the hot dog stuff….LOL!

    I meant to tell you…I made your Reeses Peanut Butter Gooey Butter Cake a few weeks ago….delicious!!



  2. says

    We are working on our back patio now and I wanted a fire pit. I like the fact that it looks like it was built in. I am gonna give a try. Thanks for the detailed info!

  3. Jill says

    Hi Erin… I have a question… Can you tell me the size of the blocks that you used. Are they 10 inch or 12 inch. And where did you get them? I have looked at Home Depot and I want to make sure I bring home the right size. The 10 inch ones are $0.99 and the 12 inch ones are $1.48. Thanks for your help!

    • says

      We used the 10 inch blocks for 99¢ each. If you’re going to buy a fire pit bowl for this at the same time you buy the stones, I would ask them to take the wire cover out of the box so you can properly measure around with the blocks like I did. Otherwise just buy a couple extras! GOOD LUCK!!

    We made a fire pit very similar to this one a few years ago. We love it and use it often. I’d like to make a suggestion to anyone who makes one. When it rains, the bowl will fill with water. Unless you plan to empty it each time, drill a hole in the bottom for drainage. Otherwise it will rust quickly and will need to be replaced. We learned that the hard way.

  5. Jennifer says

    Pretty cool!
    But if there is no glue or anything to make it stick together, how stable is it?

    • says

      Actually quite stable! The rocks are pretty heavy and the formation and insert help keep things in place. I really don’t have a lot of people bumping into though since it’s mostly filled with fire logs. If you want, you can always secure using outdoor Liquid Nails.

  6. Digna D. says

    Awesome! Thanks for posting this. We are getting a stamped concrete patio in a couple weeks and want to do a fire pit. This is perfect and looks so easy. Will bookmark for later.

  7. Carl says

    Great idea! So here’s my burning question: can you prop your feet up on the stones? Or do they shift with much force? I’d love something that also served as a footrest when not all fire-y hot.

    • says

      Use it as a footrest every single night when we sit outside. Never had one problem with shifting! I do recommend a fire pit cover if it’s rainy in your neck of the woods. I feel like I used to empty my pit weekly before I invested in one.

  8. Snehal says

    This is good idea . I have already pinned it, but I have one question..I am relatively new to all DIY projects..Where do u get those stones ?Any place to buy them ?


  9. Melissa says

    Very pretty. Has the fire affected the floor you have it on? We have a cement slab I want to put one on but 7 I am concerned of it heating up and cracking/destroying it.

  10. George says

    Great Idea, Wen’t to my local ACE/Home Depot/Lows to day and could not find the stone that you’ve used on this Project. Maybe it’s discontinued?

  11. says

    How perfect i am so going to attempt this tomorrow, We have the same fire pit. We moved into our home 7 months ago and working on the inside first. So much to do. Great idea thanks will link back to you!

  12. says

    We have a fire pit on legs like yours that is terribly wobbly! Now I know what to do!

    Your project is the most reasonably priced fire pit I’ve seen….and simple!!

  13. Monica Marchant says

    Do you feel like the bowl is deep enough to get a good warm fire going? And what do you do about rusting??

    • says

      After 1 year we haven’t had any rusting, but I guess we could always replace the bowl down the line if needed! Also, you can use this idea for any size fire pit bowl, so if you prefer wider or deeper the design is easy to adjust!
