This DIY project is not only budget-friendly but also surprisingly effective at producing mouthwatering barbecue. Let's dive into the world of cinder block smokers, their benefits, and how to build one in your backyard.
Why Choose a Cinder Block Smoker Grill?
Cinder block smokers offer several advantages that make them an attractive option for backyard chefs:
- Affordability: Cinder blocks are inexpensive, making this a budget-friendly DIY project.
- Durability: Cinder blocks can withstand high temperatures and are resistant to rust, ensuring longevity.
- Versatility: With a few design tweaks, you can create different cooking chambers for various smoking techniques.
- Portability: While not as portable as some other grill options, cinder block smokers can be disassembled and moved if needed.
Materials Needed
Before you start building, gather the following materials:

- 80-100 standard 8" x 8" x 16" cinder blocks
- Gallon-sized metal bucket with a lid
- Fire bricks (optional, but recommended for better heat retention)
- Gravel or sand
- Mortar and cement mix (optional, for a more permanent structure)
- Chicken wire or hardware cloth
- Gloves, safety glasses, and a dust mask
Building Your Cinder Block Smoker Grill
Foundation
Start by creating a stable foundation for your smoker. You can either lay down a layer of gravel or sand, or pour a concrete slab using mortar and cement mix. Ensure the foundation is level to prevent your smoker from wobbling.
Base and Firebox
Begin building your smoker by creating a square base using four cinder blocks. This will serve as the foundation for your firebox. Place the metal bucket in the center of the base, ensuring it's level. Surround the bucket with a layer of cinder blocks, leaving an opening on one side for smoke to escape.
Cooking Chamber
Stack cinder blocks around the firebox, creating a rectangular cooking chamber. Leave one side open for access to the fire and food. You can create multiple chambers by adding internal walls made of cinder blocks. This allows you to cook different foods at different temperatures.

Smoke Stack
Construct a smoke stack by stacking cinder blocks in a pyramid shape on top of the cooking chamber. Leave the top open to allow smoke to escape. You can also create a chimney effect by placing a fire brick at the base of the smoke stack, which will help regulate the temperature inside the smoker.
Door and Accessories
Create a door using cinder blocks and chicken wire or hardware cloth. This will allow you to access the fire and food easily. You can also add shelves inside the smoker using fire bricks for holding food or wood chips.
Using Your Cinder Block Smoker Grill
Now that your cinder block smoker grill is complete, it's time to fire it up. Start by adding a small amount of charcoal to the metal bucket and light it. Once the charcoal is hot, add wood chips for smoking. Place your food on the shelves or racks inside the smoker, and let the magic happen.
Monitor the temperature inside the smoker using a thermometer, and adjust the airflow by opening or closing the door and smoke stack as needed. Remember, low and slow is the key to perfect barbecue, so be patient and enjoy the process.
Maintenance and Safety
To ensure your cinder block smoker grill lasts for many years, perform regular maintenance. Clean out the ashes and debris after each use, and inspect the structure for any cracks or damage. If using mortar, touch up any areas that may have crumbled over time.
Always prioritize safety when using your smoker. Never leave it unattended, and keep a safe distance from flammable materials. Ensure children and pets are supervised when the smoker is in use. By following these guidelines, you'll be well on your way to becoming a backyard barbecue legend with your cinder block smoker grill.
