We partnered with Pavestone to try their DIY fire pit kit to perfectly match our curved retaining wall/bench. This post contains affiliate links; learn more and read our full disclosure policy here.
As part of our backyard plan at the Canyon House, we knew we wanted to build a fire pit. Nothing says summer like roasting s’mores and hot dogs!
You can build a fire pit using regular retaining wall blocks, too, but the kit makes it easy — no mortar, no cutting blocks, and the fire pit insert is included in the kit. Plus, the tumbled stone looks great!
Add some easy outdoor lighting or take it up a level and build an amazing fire pit pergola for swings and hammocks!

using a Pavestone DIY Fire Pit Kit
Note: The exact kit we used is no longer available. Pavestone’s updated kit looks exactly the same, just the insert is different. See more fire pit inserts and fire pit kits here.
DIY Fire Pit Materials
The dimension of the fire pit kit is a 46″ outside diameter.
- (1) RumbleStone Fire Pit Kit – Sierra Blend Color
- (3) Construction Adhesive (30 oz bottles)
- Concrete Mix – for the base, if desired. Quantity will depend on the size of base you need. I’d estimate 8 bags for a base that is 46″ diameter.
How to build a fire pit: step by step process
(1) Prepare the base.
You can install the fire pit on concrete like we did, or on soil/grass/etc.
For our fire pit concrete base, I had to lay a little bit more concrete to complete the circle.
See how we installed our own concrete patio here.
I added two pieces of rebar to the patio to tie the new piece in. This will keep them from settling apart from each other.
This half circle was about 4 bags. A lot easier than the 200+ for the entire new concrete patio!
I smoothed it out and let it dry.
(2) Stack the blocks together.
After about 3 days I was able to start stacking the fire pit blocks together.
All you need to do is alternate the pattern on each layer as you see here.
Center the blocks for the second row over the seams on the first row for a nice, even look.
Secure them with construction adhesive, as directed in the installation instructions.
(3) Add a top cap, if desired.
The fire pit kit makes it easy to stop here — just add the insert!
We had some leftover stone from the retaining wall and my wife had the great idea to match the fire pit to the retaining wall. Also, the added height a top cap would give seemed safer for our toddlers.
We evenly spaced the rectangular pieces then cut each triangular-shaped piece to fit its space.
See this DIY Fire Pit post for how to get the triangular-shaped pieces cut just right.
(4) Add the insert and enjoy!
We have had a blast roasting marshmallows and enjoying time around the warm fire!
And we LOVE the finished look of the curved retaining wall and fire pit together!
So what do you think of the curved retaining wall and fire pit kit? Together, they are definitely the crown to the whole backyard project!!
