For the Framework:
- 5-6 metal 2x4s
- 1-2 metal rails
- 1/2″ Self-drilling metal screws
For the Surface:
- 3 sheets of 7/16″ Wonderboard backer lite (cement board)
- 1 sheet of 1/4″ Wonderboard backer lite
- 1 5/8″ Rock-on screws
Fire Pit Components:
- 30″ x 10″ Drop-in fire pit pan
- 11 lb. propane tank
Finishing Touches:
- Thinset mortar (gray recommended)
- Concrete sealer
- Joint tape
- Adjustable furniture feet (optional)
- Recessed door ring (for propane tank access)

Building the Fire Pit Table Framework
Before diving in, decide on your desired fire table dimensions. This guide uses a 52″ length x 28″ width x 18″ height, but you can adjust to suit your space.
Pro Tip: Remember to factor in the thickness of the Wonderboard when calculating your framework measurements.
Step-by-Step Framework Construction:
-
Cut Your Metal: Begin by cutting your metal 2x4s and rails to the desired lengths, keeping in mind the 1″ deduction for the Wonderboard.
-
Construct the Base: Assemble the bottom rail using metal screws, creating a rectangular frame. This will form the foundation of your fire pit table.
-
Add Vertical Supports: Fasten the cut 2x4s vertically to the bottom rail using metal screws. These will act as the legs and provide structural support.

Secure the Top Rail: Attach the top rail horizontally to the 2x4s, creating a sturdy frame. Ensure one end has enough space for your propane tank to fit comfortably.

Pro Tips:
- Use C-clamps to hold the metal pieces in place while attaching screws.
- A magnetic level will be your best friend in ensuring your frame is level and square throughout the construction process.
Encasing the Framework with Wonderboard
Now that you have a sturdy framework, it’s time to enclose it with Wonderboard, creating a fire-resistant and durable surface.
Step-by-Step Wonderboard Installation:
-
Measure and Cut: Carefully measure and cut the Wonderboard pieces to fit around the perimeter of the fire table, leaving space for the propane tank and control panel.

Attach the Wonderboard: Use rock-on screws to secure the Wonderboard to the metal frame. Remember to pre-drill holes to make the process smoother.
"Attaching Wonderboard to frame" -
Create the Flush Lid:
- Place the fire pan in position on top of the frame.
- Cut a piece of 1/4″ Wonderboard to cover the top, creating a cutout for the fire pan to sit flush.
- Cut a second piece from the 7/16″ Wonderboard, also with a cutout. This will be your lid.

Achieving a Polished Finish with Thinset Mortar
A cement-look finish adds a touch of modern sophistication to your fire pit table. Follow these steps to get that sleek look:
Step-by-Step Thinset Application:
-
Mix the Mortar: Combine the thinset mortar according to the manufacturer’s instructions, aiming for a smooth and spreadable consistency.
-
Apply the First Coat: Using a trowel, apply an even layer of mortar to the entire table surface, ensuring to cover all the Wonderboard edges. Apply joint tape wherever two pieces of Wonderboard meet to prevent cracking.
-
Smooth and Level: Once the mortar begins to set, use a wet sponge to smooth out any imperfections and create a level surface.
"Smoothing out the mortar on the fire pit table" -
Apply a Second Coat (Optional): For a flawlessly smooth finish, consider applying a second coat of mortar, repeating the smoothing process.
-
Seal for Protection: After the mortar has completely dried, apply a concrete sealer to the entire table, following the manufacturer’s guidelines. This crucial step provides long-lasting protection against the elements.

Adding the Finishing Touches
Now comes the fun part – adding those personalized details that make your fire pit table unique.
Enhancing Functionality and Style:
-
Attach Furniture Feet: Secure adjustable furniture feet to the bottom of the table for added stability and a polished look.
-
Create the Propane Tank Door:
- Install the recessed door ring to the Wonderboard lid, creating a discreet access point for your propane tank.
- Use magnetic catches to securely attach the lid to the table.
- Add a handle for easy opening and closing.

Add Lava Rocks: Fill your fire pit pan with lava rocks. They not only enhance the visual appeal but also help distribute heat evenly.
