My DIY Electric Fireplace and Built-Ins

So we bought a 140-year old home, WITHOUT A FIREPLACE!  What?   I know, right?  Even though we inherited not one, but two chimneys, there’s no signs of an actual fireplace in our home.  So what was a girl to do when the holidays were approaching and fate put a stunning free mantel in her sights?  Build one!

Disclaimer:  this process was not well documented, however I was greatly inspired by this way more comprehensive post.  If anything, I hope my pictures are somewhat helpful if you decide to tackle a project like this.

It all really started with these cabinets:

I purchased them on deep clearance and created a fauxdenza for our dining room with them.  But my true intention for these cabinets were to build a wall of built-ins in our livingroom.  Now armed with the right materials, I was finally able to get started on this project.  So I disassembled my fauxdenza and got to work.

Can you believe someone actually gave this beauty away for free?

I wanted this built in and fireplace to look as authentic as possible, so it took a decent amount of thought as to how to make this work.

After researching several different types of fireboxes I came up with a plan to build one out of MDF.  Unlike most people, I build as I go (which usually works out) however, I do end up having to create some work arounds, and in all honesty, I have plenty of moments where I wish I would have thought things through a little deeper.

What I Knew for Sure:

  • I knew that I would need to purchase an electric fireplace insert, the larger the better, seeing that my mantel is a whopping 77″ wide, with an opening of 48″, so I needed it to be proportionate. I decided to go with an insert that was 36″ wide, leaving 6″ on both sides of the insert for the surround.
  • I needed to build a firebox/frame for my insert that had to be at least 8″ deep, I ended up going 9″ though.
  • I needed a mantel top/shelf to cover the depth of the mantel from wall to front, because my mantel is basically flat.  I ended up using a thin sheet of MDF to make this happen.
  • My wall was 24′ wide, so I had to do some simple math to ensure that everything was roughly centered (if you’re new here, please know that I’m no perfectionist!) The most important part was that the mantel and shelves that flanked it needed to take up  good majority of the wall.

My first order of business was to build a short wall the height and width of the mantel.  I attached scrap wood to the studs in the wall, and then attached the sheets cut to size for the face of my “wall”–I accomplished this by having the folks at Home Depot cut pieces of 3/4″ MDF down to the appropriate measurements:

I know this looks quite wonky, but I promise it is secure. The mantel piece was attached to the frame using 2″ finish nails.

For the sides of the “wall,”  I had a sheet of 3/4″ MDF cut down to 4-12″ panels, which once attached to the sides of the “wall”/frame/firebox, also served as the side panels for my book shelves.

I created a cleat using a 1×2 piece of pine to secure the walls and tops of the shelves.  

I cut down 4×4 blocks to serve as feet, or more so to use as a cleat for the baseboard to nail into.
The block “feet” were secured from the inside of the cabinets with screws.

The shelves for the bookcases are MDF boards also cut down to size at Home Depot, and are supported by 1/2″ poplar squares, cut to size.

The fronts of the shelves were created using 1×2″ select pine boards nailed into the MDF shelves.

Of course I had to play around with styling before it was complete

After unsuccessfully going though a pretty expensive piece of crown molding, I decided to take the easy (and way less frustrating) route and DIYed the “crown” using my old tutorial.

For the surround, instead of installing porcelain tile, I used peel and stick groutable vinyl tile in a marble look. To keep things inexpensive and fairly easy, I used a thin piece of MDF instead of using backer board to lay the tile.

I had to get creative when it came to the layout of the tile, because I wanted the veining on all tiles to go in the same direction.

My goal was to create the look of a slab of marble, so I installed the tiles very close, leaving little to no space in between. I then grouted the very thin seam, and even went over it with a little spackling, and I was able to get the look I was going for. You can see more of the behind the scenes process in my “Faux Fireplace” highlight reel on Instagram.

I then added a thin lattice strip to the edges of the tile to cover any gaps.

While the bulk of the work is complete, I still need to do some caulking, add some trim and bulk up the “crown,” but I am just over the moon with this addition to our home.  It feels like it was just meant to be in this space.  What do you think?

I’ll be back to share the completed project soon!

    It looks amazing! I draw up plans and constantly end up having to change them anyway. But, eek! The top step is NOT a step!
