Detailed Fire Pit Grill Plans
We’ve taken all the guesswork out of building a cinder bock fire pit with our descriptively written, colorfully illustrated and FREE BrickWood Fire Pit Grill Installation Instructions!
While this set of instructions requires the use of cinder block, we do offer plans that use split face block and tumbled landscape block. We also offer a TON of pre & post build information about slabs, veneers, mortars, types of wood to use (and stay away from) and much more in our Firepit Grill / Information Guide.

All projects start with Safety Glasses!
Use a string trimmer to clear an area that is 4’ in depth x 5’ wide.
After you’ve cleared the area, rake and remove any loose debris.
Position (10) of the 8” x 8” x 16” cinder blocks in the layout shown. Make sure the blocks are as close together as possible. No gaps!
Place your Level along the top of all 4 sides and corners. Make a mental note of which areas need height adjustments.
Add or remove loose dirt under the cinder block(s) that need to be elevated or lowered.
Compact any loose dirt with a hand tamper.
Use the level and the Rubber Mallet to ensure that each individual block you place into position is perfectly level. Front-to-back & side-to-side.
As you start to close the rectangle, MAKE SURE ALL (4) SIDES AND CORNERS ARE PERFECTLY LEVEL WITH EACH OTHER.
Brush / broom any debris from the top of the 1st row of cinder block.
Stagger and place the 2nd row of block on top of the 1st row of block (as shown). Use the level and rubber mallet ensure all (4) sides and corners remain perfectly level.
Once the 2nd row is PERFECTLY LEVEL, fill the inside of the firepit with (2) bags of general purpose sand.
Q: Why do I need to fill the firepit with sand?
A: Placing 100 – 150lbs of sand will not only help with rainwater drainage, it also makes cleaning / removing ash and embers a breeze. Also, it elevates the fire / cooking source closer to your food.
Q: Should I use a polyurethane adhesive between the (2) rows of cinder block to lock them in place?
A: You can, and if you do, add an additional (2) tubes of polyurethane adhesive to your Materials List. Instead, we would recommend that you fill the cinder block cores with sand & 2” x 4” x 15” cuts since polyurethane adhesive between empty cinder blocks will eventually burnout. Our Sand Core 2” x 4” Method (optional) not only locks the cinder blocks into place with natural wood and heat-insulating sand, but the dry sand inside the cores will fall into those open spaces and crevasses that are created as the firepit settles
If you want to fill your firepit cinder block cores with sand / wood – you will need an additional 250lbs of general purpose sand, a saw, and (4) sticks of 2” x 4” x 8 or (3) sticks of 2” x 4” x 10’. See more info at - bit.ly/bwo-c24
Center and place both stainless steel fire pit grill grate brackets on the top row. The sides with the 90° flange (and blue painters tape) should face the center of the firepit and there should be roughly 3” of overhang under both brackets.
Gently place (2) of the 12” x 12” pavers on the top of each bracket. This will hold the brackets in position while you make measurement adjustments with your Tape Measure.
Adjust BOTH brackets so there is EXACTLY 17.5” / 445MM BETWEEN THE 90° FLANGE BENDS. At the same time, try to keep the overhang under both brackets equidistant (about 3”).
Once your measurements are perfectly dialed-in, use the Sharpie Marker to outline where the stainless steel brackets and the cinder block intersect / overlap.
- WOBBLE CHECK -
This is your last opportunity to make sure the cinder block is perfectly level before you attach the stainless steel grill grate brackets with high-temperature silicone.
The grate should remain PERFECTLY flat. If you detect even a hint of a WOBBLE, return to Step 6 and try again…
Remove the 12” x 12” pavers – but keep them nearby. Using a Caulk Gun, apply a pencil-sized amount of High-Temperature RTV silicone to the top of the cinder block – but ONLY inside the marked area.
Press both brackets onto the Silicone and make sure the edges of each bracket are within the Sharpie markings.
Gently place (4) of the 12” x 12” pavers along the length (and on top of) both brackets. Make sure the brackets are firmly pressed against the top of the cinder block – NO GAPS.
Use your tape measure to verify that a distance of 17.5” / 445MM remains between both brackets.
Allow this step to cure for a minimum of 8 hours – 24 hours.
After a minimum of 8 hours… but preferably 24 hours has passed, remove the 12” x 12” pavers – again, keep them nearby.
Locate the center of both 54” fire pit sides (not the brackets) and use the Sharpie to mark a center-line on the blue painter’s tape on both brackets. Double check your measurements as the next 2 steps involve a lot of glue.
Apply a pencil-sized line of High-Temperature RTV Silicone across the stainless steel bracket. Make sure you stay about 1” behind the blue painter’s tape. If the RTV Silicone gets too close to the tape, the red silicone will splay over the tape and remain visible when dry.
Apply a liberal amount of polyurethane adhesive on top of the exposed cinder block (as shown). DO NOT apply adhesive to the sides of the cinder block fire pit at this time.
Place the first 12” x 12” paver into position. Make sure the center of the paver is lined-up with the line that was marked with a Sharpie (Step 12).
IT IS UBER IMPORTANT that the paver touches, but DOES NOT GO OVER the blue painter’s tape.
Attach the remaining (4) 12” x 12” pavers to finish the first row. Again, make sure the front of each paver just touches the edge of the blue painter’s tape.
As you repeat this process on the opposite row, occasionally run a grill grate along the blue tape. The grate(s) should run smoothly across the width of the grill grate brackets.
Measure the distance between the two rows (from paver-to-paver) then divide both of those measurements by 2.
For example, if both rows are 19 ½” apart, you will divide 19 ½ by 2. This will give you a measurement of 9 ¾”.
Using your measurements from Step 16, mark a cut-line on (4) of the 12” x 12” pavers with the Sharpie marker.
After you have DOUBLE-CHECKED your cut-line measurements, make sure your Safety Glasses are still on – then cut the (4) pavers to size with your saw of choice and a Diamond Masonry Blade.
Apply a liberal amount of polyurethane adhesive to the top of the remaining uncapped cinder block.
Press the (4) custom cut pavers from the previous step into place.
Allow the Polyurethane Adhesive a MINIMUM OF 24 - 48 HOURS to fully dry / cure before applying the grills &/or lighting a fire.
To prevent the cinder block from cracking, do not make excessively large fires. You should not exceed 5 pieces of firewood at one time.
