DIY Stone Firepit

I have been dying to finally share this post and unveil our beautiful, DIY fire pit with you all.  Remember this post back in April? Well we completed the first phase (the fire pit) and I could not be more happy with the results. Our little wooded oasis is becoming a reality!  Naturally, we had to have a party to show off our hard work to our friends- and I think they were impressed!  Huge thanks to Frederick Brick Works for helping us pick out the perfect veneer stone and for giving us some great tips on how to make this a successful project!  

Below you can find a step by step guide how to make your very own Pinterest worthy (in my opinion!) fire-pit that you will cherish for years to come.


Paver Base (for foundation, get enough to cover your hole 1 inch thick)

Drainage Stone (for foundation, enough to cover the entire hole 1-2 inches thick)

8X8X16 Cement Blocks (36 of them if going with our design)

3 Bags of Mortar Mix (to use on cement blocks)

32 Sq Ft worth of your favorite stone veneer. This amount includes a buffer for our design. We used Eldorado Stone– Cypress Ridge Country Side and bought a box of the corner pieces as well. We had a bunch left over, perfect for our next project

12X36X1 Flagstone (4 of them if going with our design)

12X12X1 Flagstone (4 of them if going with our design)

2 Bags of Stone Veneer Mortar Mix (to use on veneer stone)

Gravel (amount will depend- fill in around fire pit with gravel before filling in dirt, add to center of fire pit to help with drainage)



Wheel barrow or cement pan 


Metal Rake


Rubber Mallet

Masonry Slicker (or a bent spoon- no joke!)

Claw Hammer or Masonry Hammer (to break stone for a better fit)

Grout Bag


Step One: Plan Plan Plan! Where do you want your fire pit? How big? Take into consideration any future plans you may have for your yard and make sure the placement of the fire pit doesn’t conflict with those plans.  For instance, do you want to build a big deck down the road? A pool? Do you think you will add an addition to your home down the road? Where are you property lines? – you don’t want to build a large fire pit too close to your neighbor’s house (or your own!) – for privacy and safety issues.  Look around for different veneer stone, designs, etc that you like. Shop around for the best prices. 

Step Two: Buy Materials. (see above) Make sure you add in a buffer for materials in case of mistakes.  If you go with our design the above includes this buffer.

Step Three: Clear Area of any weeds, brush, etc (this was what the area looked like- luckily we did not have any trees in our way just a ton of brush!20160603-Photo Jun 03, 6 10 56 PMStep Four: Dig a 60inX60in square hole 10-12 inches deep (you can easily adjust this based on how high you want your fire pit)

Step Five: Level the dirt of the hole20160603-Photo Jun 03, 6 04 25 PM20160603-Photo Jun 03, 6 05 22 PM 20160603-Photo Jun 03, 6 06 50 PMStep Six: Lay down paver base, level and pack 20160603-Photo Jun 03, 6 31 47 PM 20160603-Photo Jun 03, 6 33 08 PMStep Seven: Lay down drainage stone, level 20160603-Photo Jun 03, 6 47 07 PM 20160603-Photo Jun 03, 6 49 19 PMStep Eight: Slap down cement mortar on outline of square.

Step Nine: Start laying first layer of cement blocks, each side should be 3 cement blocks wide. There should be a 6 inch- 10 inch gap between the outside of the cement block and the edge of the hold.  Put mortar on sides and top of cement blocks. Continue this until you are three layers high. Reinforce inside and outside corners with mortar. Let fry for 48 hours. 20160604-Photo Jun 04, 12 33 59 PM 20160604-Photo Jun 04, 3 12 18 PM 20160604-Photo Jun 04, 3 13 30 PM 20160604-Photo Jun 04, 3 14 03 PM 20160604-Photo Jun 04, 3 14 44 PMStep 10: Pour small stones around perimeter of square, fill in with dirt until it is level with the rest of the ground surrounding the pit. (you can just use dirt here if you like- the stone just helps with drainage)20160604-Photo Jun 04, 4 40 38 PM20160611-Photo Jun 11, 11 15 32 AMStep 11: Fill in small stone in center of fire pit until it is at a level you like. Too shallow and you won’t feel the heat, too high and it may damage your flagstone with the flame.

Step 12: Lay out your veneer stone and plan your pattern for the first side, use your corners as a start and work your way from left to right

Step 13: Mix your veneer mortar according to instructions in your wheel barrow and use trowel to place a small amount of mortar on the edges and center for larger stone pieces and just the center of smaller pieces (this video helped so much!) Place on cement blocks, if the stone starts to slide lean a large stone up against it to hold the veneer in place until the mortar dries a bit. 

Step 14: Continue this process until one side is complete. Repeat step 12 & 13 for each side.

Step 15: Let dry for 24 hours20160611-Photo Jun 11, 11 16 21 AM 20160611-Photo Jun 11, 11 16 28 AM 20160612-Photo Jun 12, 4 53 00 PM 20160612-Photo Jun 12, 4 53 39 PM 20160612-Photo Jun 12, 4 53 41 PMStep 16: Mix up veneer mortar and place mortar in your grout bag, slowly fill in the gaps between each stone, doing a few at a time (like icing a cake folks!)

Step 17: Grab your masonry slicker (or spoon) and smooth the grout for a refined finish, repeat Step 16 & 17 until you have gone around the entire fire pit.

Step 18: Let Dry for 24 hours

Step 19: Mix up mortar and grab a small flagstone piece. Pick a corner and line up the flagstone so it hangs over the outside edge of the fire pit between 1-2 inches, mortar it and stick it on. Next grab a large long piece of flagstone and space it about an inch away from the first piece (we will fill in mortar here later). Continue this step, alternating between the large flagstone and the small flagstone pieces (small will be used for corners only).

Step 20: Fill in 1 inch gaps between the flagstone pieces with mortar and smooth out with your slicker/spoon. Let dry 24 hours. 

*** We recommend covering your in-progress fire pit with a tarp to protect it from the rain so everything gets nice and dry.
