Why Build a Bump-Out Fireplace?

A bump-out fireplace can turn an ordinary wall into a visually striking feature. By extending the wall slightly to accommodate a recessed electric fireplace, you can achieve a built-in look without extensive construction or renovation.

Additionally, framing a fireplace bump-out provides flexibility for adding shelves, mantels, or even LED lighting around the fireplace for extra ambiance.

How to Frame a Fireplace Insert

1. Gather Materials and Tools

Before beginning, gather these materials:

  • 2x4 or 2x6 lumber (depending on your desired depth)
  • Drywall or MDF for finishing
  • Screws, nails, and drywall anchors
  • Measuring tape, level, and pencil
  • Circular saw or hand saw
  • Electric drill or screwdriver
  • Stud finder
  • Fire-resistant insulation (optional)

2. Measure and Mark the Space

Use a stud finder to locate the studs where the bump-out will be anchored. Mark these spots to guide your framing. Then, measure the dimensions of the electric linear fireplace to determine the size of the bump-out.

Pro Tip: Leave extra room around the fireplace for ventilation, as recommended in the fireplace installation manual. Ensuring proper airflow is essential to keep the unit safe and functioning optimally.

3. Start the Frame for the Bump-Out

To begin framing your fireplace bump-out, build a basic frame out of 2x4 or 2x6 lumber. Here’s how to frame a fireplace insert:

  • Bottom Plate and Top Plate:
    Cut two horizontal pieces of lumber (the bottom and top plates) to the width of your bump-out. Attach the bottom plate securely to the floor, and use screws to attach the top plate to the ceiling joists, ensuring it’s directly above the bottom plate.

  • Vertical Studs:
    Cut vertical studs to fit between the top and bottom plates. Position these studs along the width of your bump-out, leaving enough space in the center to accommodate the fireplace insert.

  • Horizontal Supports:
    For additional support, add horizontal cross-pieces within the frame, especially where the fireplace will be mounted.

This basic framing approach provides the structure you need for most fireplace framing ideas, allowing you to adjust the depth and height to match your room’s design.

4. Drywall the Bump-Out Frame

Once your frame is complete, cover it with drywall or MDF to create a smooth surface. Secure each piece with drywall screws, and finish by filling the seams with joint compound. Sand the compound smooth once it’s dry for a clean finish.

Pro Tip: For a streamlined look, consider wrapping the drywall around the edges to blend the bump-out seamlessly into the wall.

5. Cut Out the Opening for the Fireplace Insert

Next, measure and cut an opening in the drywall to fit the fireplace insert. Ensure it’s the correct size based on your earlier measurements and double-check the fireplace manufacturer’s installation guidelines.

6. Install the Electric Fireplace

Carefully slide the electric fireplace into the opening. Secure it according to the manufacturer’s instructions, which often involve screwing the unit into the frame.

  • Finish with Stone or Tile:
    Consider finishing the exterior of the bump-out with stone veneer, tile, or wood paneling for added texture and warmth.

  • Lighting Accents:
    Install LED lighting around the frame’s edge to highlight the fireplace and create a cozy atmosphere, especially at night.

  • Wood Panels:
    Shiplap, beadboard, or reclaimed wood panels are an excellent addition to a bump out. It’s a classic look and great for rustic and farmhouse styles.

  • Wallpaper:
    Place wallpaper on your bump out to make it stand out. Large-scale florals or geometric patterns are eye-catching. Wallpaper can be easily updated as trends come and go so you can do a makeover whenever you like.

  • Accent Paint Color:
    Paint your bump-out a different color from the surrounding wall. A subtle neutral or bold contrast both are appropriate depending on your taste and the style of the room.

  • Take It to the Ceiling:
    Consider building your bump out from floor to ceiling for an architectural feature that will increase value and visual impact.

FAQ: Framing a Fireplace Bump-Out

How deep should a fireplace bump-out be?

The depth of a fireplace bump-out typically ranges from 12 to 24 inches, depending on the size of the electric fireplace and desired aesthetic. This depth accommodates most electric linear fireplaces and allows for a flush, built-in look.

What is the code for framing around a fireplace?

Building codes vary by location, but in general, framing for fireplaces should follow manufacturer specifications and local building codes. Always check your local code requirements, as they may include specific insulation, clearances, and fire-resistant material guidelines.

How far should wood framing be from the fireplace?

For electric fireplaces, follow the manufacturer’s clearance recommendations. Generally, wood framing should be at least 1 inch from the unit to allow airflow and prevent overheating, but some models may require more clearance.

How high should fireplace framing be?

The height of the bump-out framing depends on the size of the fireplace and desired placement. Standard mounting height is about 40-42 inches from the floor to the center of the fireplace for an ideal viewing angle, but adjust based on the room layout and furniture.
