Several years ago, I purchased this pre-made electric fireplace for the basement. The basement does not have a heating system, and since we aren’t down there much, an electric fireplace was a great solution. It heats the room well, adds ambiance, and cozied up an otherwise cold basement.
As much as we love the look of the electric fireplace, we’ve always wanted to build a more permanent aesthetic that would add value to our home. So we decided to renovate the basement with a new fireplace surround.
Wait until you see how we upgraded a pre-made electric fireplace to a custom-made fireplace!

About Slate-ish
In my search for different products to use on the new fireplace surround, I found this product to use on the fireplace Slate-ish is made in America from scrap paper-composite materials. These solid core laminates are made from layers of paper and resin, which are heated and pressed.
It comes in 20 different colors, as well as peel and stick or loose pieces. For this project, we are using the loose pieces in Graphite 2.0.

Simple Steps to Build Your Own Electric Fireplace Surround
For our fireplace, we dismantled the pre-made electric fireplace to strip it down to just the insert.There are all different sizes of electric fireplace inserts available if you don’t already have one. I recommend that you have building experience before attempting to make this project.
NOTE: Every home is different. Sizes of rooms, ceiling height, etc. are not the same from home to home. When following this DIY, go by the measurements for your home and electric fireplace insert.
- Measure the electric fireplace and site where you want the fireplace.
- Frame out the walls of the surround based on the measurement of the electric fireplace insert. Ours is 20”x30”.
- Cut 2 – 2×4’s 5ft length for the top and bottom plates of the front wall.
- Cut 4 – 2×4’s that represents your floor to ceiling height.
- On the ground, nail the bottom plates onto the taller 2×4’s.
- Then nail the top plate onto the taller 2×4’s.
- Then pick up the wall and nail it into studs place.


- Cut 4 pieces of 2×4 to 1ft lengths.
- Cut 4 more 2×4’s to for the floor to ceiling height.
- Nail the 2 short 2×4’s to 2 tall 2×4’s twice. These are your sidewalls.
- Put the sidewalls in place. Nail it into the studs and floor.
- Then nail the side walls to the front wall, making sure it is plumb and level.
- Cut 2- 2×4’s the width of your electric fireplace insert.
- Then nail them into place for the height of your electric fireplace insert.
- (Optional: we added a tv bracket and blocking above the fireplace. If you decide to add a tv too, you’ll need to cut additional 2×4’s to support it as we did).
- Cut sheetrock to size and screw it to the studs.
- Install mantel of your choice.
Now that we have the fireplace surround built, it’s time to finish it off!


Finishing Supplies for Your DIY Electric Fireplace Surround
Keep in mind that this supply list is specific to using the Slate-ish product. If you use something different, you’ll need to adjust the following list.
- Slateish
- 100% Clear Silicone Adhesive
- Miter Saw with Carbide Tipped Blades
- Utility Knife
- Sandpaper

How to Apply Slate-ish for a Beautiful DIY Electric Fireplace
- Appy Slate-ish to a clean, flat wall surface. According to the manufacturer, the sheetrock should be painted.
- Start at the bottom of the fireplace. Level the bottom layer first before applying Slate-ish.
- Using clear 100% silicone adhesive, start at the bottom and work your way up. (Tip – use painter’s tape to hold tiles in place until dry if necessary.)
- Cut pieces to size with a miter saw, Note: carbide-tipped blades work best with this product.
- If you smear adhesive – let it dry and cut away later, or use a utility knife blade or even sandpaper to scrape off.
In order to get the look we achieved, we mitered the corners.
Note About Mitering Corners – do not attempt to miter the corners with this product. It was really extremely difficult to do and very time-consuming. Use corner trim on the corners instead of mitering.
We also added quarter round trim at the bottom, then painted it to finish off the bottom of the fireplace.




Relax and Enjoy: Your DIY Electric Fireplace Surround
We love the look of the new fireplace and can’t wait to use it this winter when the New Jersey temps drop. I love how this turned out!
I love the look and even though the corners were really tough to do, we are happy with the result.
As an aside, after working with Slate-ish product on this project, it would look amazing on an accent wall and be much easier to install.

Final Thoughts on Building a Fireplace Surround
Overall, creating this DIY electric fireplace surround was a rewarding experience, despite being more time-consuming than anticipated. The end result was a beautiful and functional addition to my living room that completely transformed the space.
However, if I were to embark on this project again, I would opt for a different material than slate-ish for the surround. While aesthetically pleasing, its brittle nature and sharp edges made it challenging to work with, particularly for a beginner DIYer.
Despite this minor setback, the sense of accomplishment in crafting a unique piece for my home far outweighs any difficulties encountered along the way.
