DIY fireplace ideas can bring warmth and a striking focal point to a room, whether you are working with an existing fireplace, adding an electric insert, or creating a decorative mantel. These 16 examples cover a range of styles, budgets, and skill levels, with options for indoor spaces and covered porches.
Before choosing a design, consider where the fireplace will go, how it will be used, and what kind of insert or firebox the space can safely accommodate. Electric models, decorative faux fireplaces, and gas units each have different installation requirements. For outdoor projects, select equipment specifically rated for the location and follow the manufacturer’s installation guidance.
Planning a DIY Porch Fireplace
A porch fireplace can make an outdoor living area feel more inviting and give an unused wall a clear purpose. In one porch layout, a television and mini refrigerator were no longer needed after an outdoor kitchen and backyard updates were completed. A temporary faux mantel and shelf offered a simple way to define the space while a more permanent fireplace was being planned.
When planning a similar project, measure the wall and check the surrounding materials before selecting a mantel or insert. Keep required clearances around heating equipment, and confirm that the fireplace is suitable for outdoor conditions if it will be installed on a porch.
16 DIY Fireplace Ideas for Any Room
The designs below include electric fireplaces, faux surrounds, built-in storage, and updates to existing fireplaces. Many can inspire a living room, family room, dining area, bedroom, or covered porch. Adapt the finishes and proportions to suit the space rather than copying a design without checking its dimensions or installation needs.
1. DIY Faux Plaster Fireplace Surround
Chelsey Freng created a clean, modern surround that can be built around an electric fireplace or used to refresh an outdated fireplace. A simple finish can help the fireplace blend with contemporary interiors. Before building, confirm that the chosen materials are appropriate for the fireplace’s heat clearances.
2. Bold DIY Fireplace Surround
Lindsay of The White Buffalo Styling Co. updated an existing fireplace with tile, molding, and bold green paint. This approach shows how color and trim can transform a fireplace without changing its basic position. Test paint colors in the room’s lighting before committing to a large surface.
3. Electric Fireplace with a Custom Surround
Angela Rose built a frame around an electric insert and added a modern surround finished to resemble concrete. A framed design can give a standard insert a more integrated appearance. Check the insert’s installation instructions before enclosing it, particularly where ventilation or access panels are required.
4. Built-In Electric Fireplace with Venetian Plaster
Jenna Sue Design used real Venetian plaster to finish a built-in electric fireplace. The polished surface creates an elegant look, while limewash paint is another way some DIYers create a softer plaster-inspired effect. Choose a finish based on the texture and maintenance needs you prefer.
5. Faux Fireplace with a French Marble Look
Autumn Williams updated a replica French-style surround with ceramic tile for a faux hearth and a black-painted interior that suggests a firebox. This decorative approach requires less building work than constructing a full fireplace. Keep decorative materials away from any active heat source unless they are suitable for that use.
6. Electric Fireplace with Built-In Shelves
Made by Carli paired a thrifted mantel with prefabricated cabinets and MDF bookcases to add storage around an electric fireplace. Combining ready-made and custom components can help manage costs. Measure the insert, cabinets, and shelves together so the finished arrangement looks balanced.
7. Faux Cast-Stone Fireplace Mantel
Cami and her husband from Tidbits & Company shaped pliable particle board and sheetrock into a curved mantel and surround, then used joint compound to create a cast-stone-inspired finish. This method offers a decorative alternative to solid stone. Allow finishing compounds to dry fully between steps for a more even surface.
8. Electric Fireplace with an Antique Mantel
Erin Zubot Design framed an electric insert with black marble tile and topped it with an antique mantel. The contrast adds a dramatic, traditional character. Check that a reclaimed mantel is stable and that its dimensions work with the insert’s required clearances.
9. Electric Fireplace Between Two Windows
Angela Marie Made placed a simple electric fireplace between two living-room windows. The reported material cost for the project was $550. For a layout like this, plan the fireplace and window spacing together, and include the cost of finishing materials and any electrical work in your budget.
10. Fireplace with Hidden Cabinets
Kimberly at Avalanche Design Co. incorporated concealed side cabinets into an electric fireplace build. Hidden storage can keep everyday items close by without making them a visual feature. Make sure cabinet doors and stored items do not block access to the fireplace or its controls.
11. Semi-DIY Gas Fireplace
Oho Interiors used a gas insert to create a navy-blue focal wall, completing part of the surrounding build themselves. Gas fireplace installation involves fuel connections and other safety considerations, so qualified professionals should handle work that requires specialized expertise. Image: Tiffany Kokal.
12. Modern Fireplace with a Wood Mantel
Christina from Ellis and Hale used joint compound to create a plaster-inspired finish and added a simple wood mantel for warmth. This combination pairs a clean surface with a natural accent. Follow product guidance for the finish and keep the mantel at the required distance from the heat source.
13. Traditional-Style Electric Fireplace
Mrs. Jessica Darling added dental molding to an electric fireplace wall for a traditional detail, then finished it in sage green-gray. Decorative molding can give a straightforward build more character. Use a level and plan the trim layout before attaching it to keep the details consistent.
14. Modern Fireplace with Roman Clay
Danielle from Our Nest On Powell used Roman Clay as a finish over drywall for a sleek fireplace design. A layered finish can add subtle texture without relying on a highly decorative surround. Prepare the wall according to the finish instructions to help achieve an even result.
15. Covered Porch Fireplace
Sherry H Designs, Ladisic Fine Homes, and Linda MacArthur Architect created a covered-porch fireplace framed by white brick, including a distinctive curved shape. Although it is not a DIY example, it offers inspiration for outdoor layouts and proportions. Confirm local requirements and use materials and equipment suited to the porch environment.
16. Outdoor Brick Fireplace
Brooke and Henry from Plank & Pillow feature an outdoor white-painted brick fireplace and show a television mounted above it. The placement and overall shape can help with planning a covered outdoor living area. Before mounting a television, check the fireplace and television manufacturers’ guidance about heat exposure and safe placement.
Choosing the Right DIY Fireplace Idea
The best choice depends on the room, the available space, the desired function, and the amount of work involved. A decorative faux fireplace can provide a focal point without a working fire, while an electric insert can add heat if the model is designed to do so. Built-in shelves or cabinets may make a fireplace wall more useful, and an existing fireplace may need only a new surround or finish.
Compare project dimensions, materials, and installation requirements before starting. For any fuel-burning unit or work involving electrical, gas, or structural changes, consult the appropriate qualified professional and follow applicable local rules. With careful planning, these DIY fireplace ideas can help create a focal point that suits the space and its intended use.
