I looked at different mantel options when we decided to update our fireplace.  The range of pricing was huge from a few hundred to thousands of dollars.  This mantel cost us under $50!!!

So if you can build it yourself, why not?

You’ll need to adjust the board sizes to fit your mantel size to make this tutorial work for you.  You’re creating a hollow box with an open backside.

How To Build A Rustic Mantel

We started by assembling the cleats that would be holding the mantel to the wall.

You’re going to use the 2″ x 4″‘s for this.  Take your 28″ pieces and attach a 9″ piece on either side.  We used the 2″ wood screws to secure them together.

Then using your stud finder, secure the cleats to your wall, using the 2″ wood screws to attach to the studs.

Unstained wood mantel

Now it’s time to build your fireplace mantel box.  Your 1’x10″ lumber pieces are the top and bottom of the DIY mantel. The 1″x6″ pieces are the sides. Use your nailer to attach all the pieces. You can use wood glue between the pieces before using your nail gun if you prefer, that can help tighten up your seams if you want a cleaner look.

Fill in the nail holes with wood putty.  Once the putty is dry give the mantel a really good sanding with some medium grit sandpaper.

Then I took a couple of wet paper towels and wiped down the wood to get all the excess sawdust off before staining. You can distress your mantel by hitting it with a hammer or banging it with some chains.

Stained DIY Mantel

Kona is my go-to wood stain in my home!  I love its deep, rich tones, yet you can still see the grain. Then apply the stain with a foam brush and then wiped it off with an old rag a couple of minutes later. I like to use the stain with the polyurethane included. This mantel didn’t need multiple coats of poly, so that makes it much easier to finish your new mantel.

Once it was dry it was time to put up the wood mantel!!!

Installing Rustic Fireplace Mantel

We just slid the mantel onto the cleats.  We used the 2″ wood screws to attach the mantel to the cleats, placing one screw on either side of the mantel. You could also attach the mantel from the bottom of the mantel to the cleats.
