A DIY fireplace makeover with a tutorial to build a DIY fireplace surround creating a beautiful updated fireplace. This tutorial covers how to update a 90s era fireplace by creating a beautiful DIY fireplace surround.
This whole project started as a real life “If You Give A Mouse A Cookie” scenario. Matt and I were chatting about our fireplace and how we’d love to get rid of the faux marble surround and potentially add a mantel. That Saturday afternoon conversation quickly turned into curiosity and we began wondering what was behind the marble surround anyway? How difficult would it be to remove it? Could we DIY a mantel? Next thing I knew, while I was googling fire code for fireplaces, Matt was pulling the trim away from the wall around the fireplace just to see what was behind the fake marble. After about five minutes we had the entire surround removed from the wall and we were staring at each other trying to convince ourselves that this would be easy enough. Our fireplace makeover was off to the races with this DIY fireplace surround.
I reached out to my friends at Floor & Decor to ask if they might want to team up with me on this project. I was so excited when they agreed because I had my eyes on the most perfect gray hexagon porcelain tile.
How to Build a Fireplace Surround
To build the fireplace surround, we first started by pulling off the existing faux marble surround. When we pulled off the faux marble the fireplace looked like this. We started by tiling the fireplace surround. Since we were building out a fireplace surround we knew it would be larger than the previous so we also pulled off a portion of the baseboard on both sides of the fireplace. Since we just had drywall all the way around the fireplace, we had to reinforce it with cement board before placing the tile.
To prepare the fireplace surround for tile, we added some 1/2 inch edging around the fireplace, called an aluminum Schluter, to give a nice clean edge where the tile meets the fireplace. It’s installed behind the cement board so that it would be flush with the fireplace. You can see it in the photo above. If you don’t use cement board you could use an even slimmer Schluter edge.
I’m going to go into detail how we assembled our fireplace surround, keep in mind to follow your state’s fire code guidelines. Here are few quick details: Our final measurements for the fireplace are as follows: 55 inches wide, with the mantel being 70.5 inches, and 53 inches high. Of course, you’ll be building your according to the size of your space but just as a general FYI.
We later painted the gold hardware black with fireplace paint.
Since we knew we would be building out a surround and mantel, we only added about six inches of cement board where we would be placing tile.
SUPPLIES WE USED FOR THE TILE
10 square feet of gray hex tile
Matt was able to bust out the tiling in just an afternoon. It turns out that these hex tiles are WAY easier than the herringbone marble we used in our kitchen.
We grouted the tile the next day. I love the way the white grout pops on the gray tile!
Next, it was time for the real fireplace makeover – building the fireplace surround.
To build the column, Matt essentially built a “C” using a 1×6 and two 1×3. He joined them together using the Kreg Jig pocket hole system. This allows you to join corners together without any screws exposed on the outside.
He used pieces of 2×4 cut down to allow the column to fit snugly around them and then secured the column to the pieces of wood using our brad nailer. Notice the marks on the wall – he marked the wall with a pencil so he would know exactly where the 2×4 blocks were when it was time to nail the column in place.
I got a little excited as we moved forward quickly from here so I missed a photo of the next step which was to attach the 1×10. And actually, ours is a 1×8 (you can see the gap between the front board and the top the mantel in the image below). We originally got a 1×10 piece of wood and it was warped so we decided not to use it. When we went to grab another piece we picked up a 1×8 by accident. We didn’t want to make another trip out and the gap is covered by trim so… use a 1×10! 🙂
Again, we used 2×4 pieces with shims jammed in to cover the difference and to make it flush with the columns. Then nailed the front board into place.
For the fireplace mantel, we framed out a 1×8 board with 1×2 pieces with mitered corners to create chunky looking mantel top. We nailed the top to the 2x4s and straight into the columns. You’ll also notice Matt added a few pieces of 1×2 in the gap so that the mantel top would be really secure – if you get the right size board (1×10) to begin with you wouldn’t need to do that.
After the mantel was up we started to add the trim – this is where you can be creative to get the fireplace look you dream off. For our fireplace makeover, we added 1×4 around the bottom of the columns, and then put 3/4 in cove molding in around the perimeter of the fireplace. This was to hide the cut edges of the tile and any imperfections.
We added crown molding directly under the mantel, then added a piece of 1×2 directly underneath it to chunk it up even more.
To trim out the rest of the mantel, we used 1×2.
Once all the trim was finished, we sanded the entire thing down with an orbital sander. Then we caulked all of the many brad nail holes and seams and finished it with paint. We painted two coats of Benjamin Moore Swiss Coffee and called it done.
Matt claims this was our biggest project yet on the house probably because the building of the mantel was time-consuming that required a lot of precision – cutting crown molding is no joke, friends!
As I mentioned before, to complete the fireplace makeover we ended up painting the brass hardware BLACK. You can see that easy and cheap process of using high heat paint to update your fireplace here. I’m so proud of the way our fireplace makeover (and especially the DIY fireplace surround) turned out. It’s the best feeling when an idea you have turns into a real life beautiful project you love!
