I honestly never thought I'd be the kind of person to attempt a diy fireplace electric project, but after seeing the price tag on those pre-made stone mantels, I changed my mind pretty quickly. There is something incredibly satisfying about taking a blank wall and turning it into a cozy focal point without having to call in a contractor or mess around with gas lines. If you've got a spare weekend and a basic drill, you can actually pull this off way easier than you might think.
The best part about going the electric route is that you don't need a chimney, and you certainly don't need to worry about carbon monoxide. It's essentially a fancy space heater that looks like a million bucks. You're basically just building a wooden frame to house a plug-in unit, and once you realize that, the whole project feels a lot less intimidating.
Why you should build your own
Most people go out and buy those cheap, particle-board media consoles with the "fireplace" built in. They're fine, I guess, but they usually look a bit flimsy. When you take on a diy fireplace electric build, you get to decide exactly how tall it is, how wide it is, and what kind of finish it has. Want it to look like a modern farmhouse with shiplap? You can do that. Prefer a sleek, minimalist concrete look? You can do that too.
It's also way cheaper. I priced out a high-end electric fireplace unit that came with a mantel, and it was nearly two thousand dollars. By buying the electric insert separately and building the surround myself, I saved over a grand. Plus, I was able to customize the depth so it didn't stick out too far into my walkway, which is something you just can't do with store-bought furniture.
Choosing the right electric insert
Before you even think about buying lumber, you need to pick your insert. This is the heart of your diy fireplace electric setup. There are two main types: the kind that slides into a mantel and the kind that gets recessed into the wall. For a DIY hearth build, you usually want the "plug-in" or "insert" style that vents heat out the front.
Make sure you check where the heat comes out. If the vent is on the top, you have to be really careful about leaving enough clearance so you don't accidentally start a fire inside your wooden frame. Most modern ones vent from the front, which is perfect for this project. Also, look at the flame effects. Some look like a weird 90s screensaver, while others look so real you'll catch yourself trying to warm your hands over "flames" that are actually just LEDs and mirrors.
Planning and framing the surround
Once you have your insert sitting in your living room, it's time to start the "build" part. I usually recommend using 2x4s for the framing because they're sturdy and cheap. You're essentially building a small wall that sticks out from your existing wall.
Measure your insert twice—honestly, measure it three times. You want the opening to be just a tiny bit larger than the unit so it slides in smoothly, but not so big that there are gaping holes around the edges. When I did mine, I built a base (the hearth) first to get it off the floor, then built the vertical frame on top of that.
Pro tip: If you want to hang a TV above your fireplace, make sure you add extra blocking (horizontal 2x4s) in the frame where the TV mount will go. Trying to find a stud through shiplap or tile later is a nightmare you don't want to deal with.
The wiring situation
Since this is a diy fireplace electric project, you're going to need power. Most of these units just plug into a standard 120v outlet. If you're lucky, you'll have an outlet right where you're building. If not, you might want to call an electrician to move one for you.
I've seen people use extension cords hidden inside the frame, but I really wouldn't recommend that. These heaters pull a lot of juice, and hiding an extension cord behind a wall is a major fire hazard. It's worth the hundred bucks or so to have a professional put a dedicated outlet right behind where the insert will sit. It makes the whole thing look much cleaner since there aren't any wires trailing across your floor.
Finishing the exterior
This is where the magic happens and your diy fireplace electric unit starts looking like a real architectural feature. You have a few options here depending on your skill level and the "vibe" of your house.
Shiplap and wood planks
This is probably the easiest route. You just nail the boards directly to your 2x4 frame. It's very forgiving because if your cuts aren't perfect, you can usually hide the gaps with a little bit of caulk and paint. It gives that classic "Pinterest" look that everyone seems to love right now.
Stone veneer or tile
If you want something that looks more permanent, go with stone veneer. It's basically thin slices of real or manufactured stone that you "glue" onto the frame using mortar. It's heavy, so make sure your framing is solid. If you go this route, you'll need to put up cement board (like Durock) over your 2x4s first, because mortar won't stick well to plain plywood or drywall.
The Mantel
Don't forget the mantel! A thick piece of reclaimed wood looks incredible on top of a diy fireplace electric build. You can buy pre-finished mantels, or just get a "6x6" beam from a local lumber yard, sand it down, and stain it yourself. It really ties the whole look together and gives you a place to put your holiday decorations or a few candles.
Common mistakes to avoid
I've made plenty of mistakes on my own projects, so hopefully, you don't have to. The biggest one is not accounting for the trim. If you're planning on putting baseboards around the bottom of your fireplace, remember that they add thickness. You don't want your fireplace to look like it's "floating" weirdly because you didn't think about how it meets the floor.
Another thing is the depth. A lot of people make their diy fireplace electric surround way too deep, and it ends up eating up half the living room. Most electric inserts are only 6 to 9 inches deep. You only need the frame to be deep enough to house the unit and maybe a little bit of breathing room behind it.
Lastly, don't forget about the "click." Some electric fireplaces make a slight clicking noise when the flame motor is running. Check the reviews before you buy! It's a small thing, but if you're sitting in a quiet room, it can get annoying pretty fast.
Living with your new fireplace
Once it's all finished, the feeling of turning that thing on for the first time is awesome. You can have the "flames" on without the heat during the summer just for the ambiance, which is something you can't really do with a real wood fire.
It completely changes the mood of the room. It goes from a flat, boring wall to a cozy nook where everyone wants to hang out. And when people ask who installed it, you get the bragging rights of telling them it was a diy fireplace electric project you did yourself. Honestly, it's one of the best bang-for-your-buck home improvements you can do. It adds value to the house, saves you money on the install, and makes those cold winter nights a whole lot more bearable.
