Rough Hewn Wood Fireplace Mantel

A chunky wood mantel can add warmth to a room. In this project, it is used to break up the large expanse of a fireplace brick wall. Furthermore, it reduces the impact of the brick wall even more.

The mantel is built using pieces of lumber. This mantel needs to have a distressed look. To achieve that, use lumber that has knots, marks, and cracks.

The mantel is mounted on the brick wall, about one foot above the fireplace. It resembles an open wooden box turned upside down. The top can function as a shelf.

The warm look of wood is achieved by adding a dark brown stain. This project costs a total of $25, which is a huge saving compared to the store-bought price of $200.

A nice pine trim sits above the box beam. This wide trim acts as a shelf. The trim is stained dark brown while the pillars and beam box are painted white. This gives a beautiful color contrast.

Drywall anchors and corbels support this mantel shelf. Amy adds a beautiful crown molded board to the face of the shelf.

This is a photo-heavy tutorial, which is exactly what most DIYers want. It is more of a makeover project, and building a deep mantel is one of them.

The background of the mantel is given an updated look. This is achieved by painting the wall over the fireplace.

The reason for building a deeper mantel is to make it beefy enough to double as a storage shelf. Furthermore, it looks more decorative compared to a shallow fireplace mantel.

The entire section of the shelf and pillars are adorned with crown moldings. A gorgeous marble hearth surrounded by a chunky wood trim brings a new face to the fireplace.

The whole thing is primed and painted in glossy white. This is a neutral color that blends well with most home decors. Design by Shannon.

You can enjoy the beautiful look of a mantel even when there is limited space around the fireplace. The solution is to consider a slim-lined mantel surround.

Abi calls her creation a wrap-around-mantel. It looks simple and has a clean line. She uses wooden boards to build it. Cedar is what she settles for, which is actually a top preference in this kind of job.

Abi wants a mantel surround that is more than just a decorative piece. So she adds a wider board to the top to create a shelf.

Gaps between the fireplace wall and the mantel are filled up with grout. The simplicity of this project makes it a one man’s task.

8. Mantel Surround with Double Shelves

A light, classic mantel surround can make a bold statement. The impact is even greater when you add two shelves to it.

Everything about this mantel surround screams coastal. You know what, the rustic finish is a big plus for homes with wooden floors.

She builds the beam using thick MDF oak boards. From a distance, it looks like a solid piece of wood.

The top section of the beam is wide. Such a size makes it double as a mantel shelf, which is a nice extra. A distressed look on the beam adds a nice weathered look that stands out in any setting.

10. Chunky White Mantel Shelf for Stacked Stone Wall

The idea here is to get rid of that plain look of the wall surrounding the fireplace. I think you will love the creativity that Aniko puts here.

What she wants is a chunky shelf that is decorative and functional. She chooses a white finish to contrast beautifully with the dark stone background.

Building this box mantel isn’t a challenge. After all, what you need to do is just cut to size and assemble the panels together.

The challenge comes when mounting on the stone wall. This is where you might need a helping hand to displace some stones and drill through. Drilling is done to install wooden stud supports to the wall.

Aniko says the project has been a great success. Now she gets somewhere to place her pretty work of art. She calls it a cool transformation from plain to awesome!

Custom fireplace mantels are a good way of getting a mantel surround that matches the style of your room and fireplace. Such is what Chelsea has in mind.

This is a complete makeover project and the way it is done is simply fantastic. Gina Luker uses wood salvaged from the old mantel. In short, she doesn’t spend a penny on additional materials.
