An unused fireplace can feel like wasted space, or an opportunity. Whether your chimney no longer draws properly, you’ve switched to radiant heating, or you’ve simply outgrown the room’s layout, covering that dark opening transforms it from eyesore to focal point. The good news: there are dozens of practical, stylish approaches that range from weekend projects to permanent installations. This guide walks through decorative screens, functional inserts, wall treatments, and budget-friendly DIY solutions. Each method addresses the core issues: blocking drafts, improving aesthetics, and reclaiming the wall’s design potential.
Key Takeaways
- Unused fireplace cover ideas range from reversible decorative screens ($100–$400) to permanent solutions like shiplap and tile veneers, allowing you to choose based on budget and commitment level.
- Functional covers address energy loss by sealing drafts—use chimney balloons ($20–$50), rigid foam inserts, or built-in frames to reduce heating and cooling costs.
- Most fireplace cover projects cost under $300 in materials and take a weekend to complete, including budget options like paint refresh, plywood covers, or pallet wood designs.
- Transform your fireplace into a feature wall by adding floating shelves, built-in storage, or artistic finishes like wallpaper, painted accents, or stone veneers for both style and functionality.
- For renters or those testing ideas, choose reversible solutions such as removable wallpaper, fabric panels on tension rods, or freestanding screens that require no permanent installation.
- Always inspect your chimney with a licensed sweep before sealing to ensure it’s safe, check local building codes for permit requirements, and measure carefully before beginning any project.
Decorative Fireplace Screens and Modern Designs
A fireplace screen is the quickest, most reversible option. Modern screens go far beyond the brass-and-mesh aesthetic of decades past. Today’s designs include flat-panel metal screens (powder-coated steel or aluminum), minimalist wooden frames, or ornamental iron with geometric patterns that complement contemporary or traditional interiors.
Freestanding screens lean against the fireplace opening without fastening. They range from 3 to 5 feet wide and typically cost $100–$400. The upside: no installation, no damage to the chimney. The downside: they don’t block drafts or heat loss: a fireplace opening still pulls conditioned air up the chimney.
Built-in screens mount directly to the fireplace surround or wall studs, creating a snug fit. Installation takes 30–60 minutes with a drill and appropriate fasteners (toggle bolts if hitting drywall, lag screws if anchoring into masonry). Measure twice before drilling, you can’t easily remove holes from a fireplace facing. A professional designer or contractor might charge $500–$1,500 for custom metal work, but pre-made options run $150–$600 installed.
Consider the room’s lighting and existing finishes. A polished steel screen in a rustic room feels jarring: matte black or wrought-iron styles tend to blend better. If you’re renting or want to test the look first, lean toward freestanding designs.
Functional Fireplace Inserts and Covers
When aesthetics alone aren’t enough, functional inserts address the core problem: energy loss. An unused chimney is an open door to conditioned air escaping in winter and hot air entering in summer. Building codes in many jurisdictions (check your local IRC or equivalent) recommend sealing unused chimneys at both the roof and the inside of the home.
Chimney balloons are inflatable vinyl plugs sized for your flue opening. They cost $20–$50, install in minutes, and block air flow without damaging the chimney liner. The catch: they’re temporary and must be removed before using the fireplace. Label them clearly so family members don’t accidentally leave them in place.
Fireplace inserts, whether decorative or functional, sit inside or in front of the fireplace opening. Decorative versions are framed panels or covers made from plywood and finishing materials. A basic framed insert (1×2 lumber frame, drywall, paint) is a solid weekend project: measure the opening, build a frame that sits flush inside or slightly proud of the opening, secure it with screws (not nails, vibration loosens them), and finish with paint or trim. Cost: $30–$100 in materials.
For better insulation, consider a rigid foam insert behind the cover. 1-inch rigid foam board (R-5 to R-6 value) is cheap ($10–$20 per sheet) and straightforward to fit. Tape seams with painter’s tape or caulk to minimize air gaps. This won’t solve drafts from a leaky damper, but it reduces overall heat loss. If your damper or chimney liner is damaged, consult a licensed chimney sweep before sealing, you may need repairs first.
Artistic Wall Treatments to Transform Your Fireplace
The fireplace opening itself is a blank canvas. Mural painting, wallpaper, or textured finishes can turn the surround into a feature wall that makes you forget there’s ever been a hearth underneath.
Wallpaper and shiplap work well for disguising the opening. Peel-and-stick removable wallpaper is renter-friendly and takes 1–2 hours to apply. Measure the opening and surrounding wall, cut a piece to size (add 2 inches for overlap), and smooth it down with a squeegee to avoid bubbles. Shiplap requires more effort, measure, cut, and nail (or screw) 1×6 or 1×8 boards vertically or at an angle. Budget 4–8 hours for shiplap on a standard fireplace surround, plus primer and paint.
Painted finishes are the cheapest transformation. A bold accent color (navy, charcoal, or terracotta) draws the eye to the shape rather than the function. For a modern twist, try color blocking: two or more paint colors in geometric sections. Use painter’s tape to define clean lines. Apply primer first (especially important on fireplace brick, which is porous), then two coats of quality interior paint. Don’t scrimp on primer, it seals the surface and prevents bleed-through.
Stone or tile veneers mimic a professional-looking surround. Lightweight veneers (slate, marble, or faux stone panels) adhere with mortar or construction adhesive. This requires surface prep: clean the existing surround, sand any glossy paint, and score the surface for better adhesion. Measure and dry-lay your veneers first to minimize cuts. Grouting takes patience but adds a polished finish. DIY veneer projects typically take a weekend and cost $200–$600 in materials.
Creating a Feature Wall with Shelving and Storage
Transform the fireplace into a built-in storage or display area. This works particularly well for shallow fireplace openings or where you want the wall to serve a functional purpose beyond decoration.
Floating shelves mounted above the fireplace opening create gallery space for books, plants, or decor. Install shelves 12–18 inches apart vertically, using lag screws or wall anchors rated for at least 25–30 pounds per shelf (always exceed expected load). Locate studs if possible, mount directly into them with 3-inch lag screws. If mounting into drywall only, use toggle bolts or heavy-duty anchors. A shelf that sags or pulls free is dangerous and ruins the look. Most floating shelf kits cost $15–$50 per shelf: installation takes 30 minutes if studs align, longer if you’re finding alternative anchors.
Built-in cabinets or cubby storage flanking the opening maximize functionality. This is more ambitious, you’ll frame a structure, install a backing board, add adjustable shelves or doors, and paint or stain. If your fireplace opening is structural (part of a load-bearing wall), don’t remove or alter the surround itself: instead, build around it. This is where a second pair of hands, a miter saw, and careful measurement pay off. The payoff: permanent, custom storage that increases home functionality and resale appeal.
A TV above or beside the opening can also work, though many interior designers advise against mounting directly above because height becomes awkward for viewing. A TV wall adjacent to the fireplace, with shelving organized around both, creates a cohesive media zone.
Seasonal and Reversible Cover Solutions
If you’re undecided or renting, reversible solutions let you test ideas without commitment. These are also smart if you ever plan to restore the fireplace later.
Fabric panels or curtains hung on a rod or tension wire in front of the opening soften the appearance. Use heavy linen or velvet (not sheer) to block some draft: lightweight fabrics are purely decorative. A simple tension rod mounted inside the fireplace trim takes 15 minutes and costs $10–$25. Swap fabrics seasonally, darker tones in winter, lighter in summer. This approach is especially popular for cosmetic coverage without permanence.
Wooden frames with removable inserts let you change the look seasonally. Build a simple frame that fits your opening (measured to the inside edge of the trim), then create removable panels (plywood or hardboard) finished with paint, wallpaper, or fabric. Slide or clip the panels in and out. Cost is modest ($50–$150), and you gain flexibility.
Temporary adhesive removable wallpaper or wall decals offer the quickest fix. These don’t damage paint or finishes when removed, making them ideal for renters. Most remove cleanly if applied correctly to a clean, dry surface. Avoid applying to freshly painted walls or surfaces with texture (brick or stucco) where adhesion is unreliable. The Spruce covers home decor ideas that include temporary decorating solutions if you want inspiration.
Firewood storage inside the opening (if the space is deep enough) is functional and rustic. Stack firewood neatly, cord-cut logs are about 16 inches long and 4 inches in diameter. Keep logs off the floor on a simple wooden rack to allow air circulation and prevent moisture buildup. This works best if you actually burn occasional fires: otherwise, it’s wasted space filled with something you don’t use.
Budget-Friendly DIY Fireplace Cover Projects
If your budget is tight, start with what you have and what you can buy affordably.
Paint and caulk are the cheapest refresh. Clean the fireplace surround thoroughly (use TSP, trisodium phosphate, or a degreaser to remove soot and buildup). Fill gaps around the opening with paintable caulk, sand smooth, and paint with a high-quality primer and interior latex paint. A good paint job costs $20–$50 and transforms the look dramatically. Many overlooked fireplaces just need a deep clean and a fresh coat of color.
Plywood covers are a DIY classic. Cut a piece of 3/4-inch plywood to fit your opening (measure width and height inside the trim), prime both sides (prevents warping), and paint or finish to match your decor. Mount it with 3-inch screws into the surround or into studs if the opening is very large. A basic plywood cover costs $25–$50 and looks temporary, suitable while you plan something permanent.
Pallet wood offers a rustic, budget aesthetic. Disassemble pallets (use a pry bar or reciprocating saw with a metal-cutting blade), sand the boards smooth, and arrange them horizontally, vertically, or in a pattern across the opening. Secure them to a backing board with finish nails or screws, then mount the whole assembly. This is a fun weekend project if you enjoy the industrial-farmhouse look. Cost: free to $30 if you source pallets locally.
Fabric draping (mentioned earlier but worth repeating for budget-conscious DIYers) requires only fabric, a rod, and basic hardware. Hang a decorative fabric panel on a simple rod. For under $25, you have a soft, changeable cover. Today’s Homeowner provides seasonal repair guides that include budget-friendly updates.
No-tool options include placing a large mirror in front of the opening (reflects light and expands the room visually) or a tall decorative screen leaned against it. These require zero installation and cost $30–$150 depending on quality. Test the look before committing to permanent solutions.
Conclusion
Covering an unused fireplace isn’t a one-size-fits-all fix. Your choice depends on whether you want reversibility, permanent aesthetics, energy efficiency, or function (storage, display, or insulation). Start by addressing the core issue, drafts and visual impact, then layer in style. Most projects take a weekend and cost under $300 in materials. Before you begin, ensure your chimney is safe (have a licensed sweep inspect it if there’s any doubt), check local codes for permit requirements, and measure twice. The fireplace is one of the focal points in a room: treat it as an opportunity, not a problem.
