Building a Walnut Vanity with a Live Edge Backspalsh

In this episode, I build a Custom walnut vanity with a live-edge backsplash. This Colorado Springs custom furniture client wanted a contemporary floating custom vanity with some rustic appeal. To accomplish this, we created a vanity with a beautiful contemporary look by adding an Onyx base and a Walnut live-edge backsplash to give it that Mountain Modern look.

Crafting a Stunning Walnut Vanity with a Live Edge Backsplash

There’s something incredibly satisfying about transforming raw lumber into a functional and beautiful piece of furniture. In this project, I built a walnut vanity with a live-edge backsplash—a piece that combines natural beauty with precision craftsmanship. Here’s a step-by-step look at how it came together.

Prepping the Lumber

I started by milling the walnut boards, running them through the jointer to get a flat edge, and then through the thickness planer for a consistent thickness. To ensure a strong bond when gluing up the vanity top, I used dominoes for alignment and added stability.

Addressing Imperfections with Epoxy

One of the boards had a bark inclusion—a natural flaw that needed attention. To fill it, I mixed black dye into epoxy and added a small amount of denatured alcohol to thin it out. This helps the epoxy flow deeper into cracks, minimizing bubbles. After pouring, I used a heat gun to remove any remaining bubbles for a smooth, seamless fill.

Cutting Custom Angles

The customer wanted a unique angle for the vanity, so I measured on-site and transferred those dimensions to the wood. Using a homemade shop sled, I guided my circular saw to make the cuts. For the mitered edge where the backsplash would meet the vanity top, I attached a piece of pine with CA glue to act as a guide along the table saw fence. This ensured a clean, straight cut while keeping the process safe and controlled.

Dialing in Compound Angles

Off-camera, I used scrap wood to test and dial in the compound angles needed for the apron. Once I had the perfect fit, I cut the actual pieces and used glue blocks to clamp the miters tightly together. Some viewers suggested blue tape for alignment, but on a piece this large, tape alone wouldn’t hold. Instead, slow-setting epoxy gave me time to adjust the fit perfectly while also filling any minor gaps.

After the epoxy cured, I chiseled off the glue blocks and sanded everything smooth.

Supporting the Weight with Cleats and Webbing

Given the vanity’s weight, I reinforced the back with a French cleat system, secured with screws and dominoes for extra strength. I also glued two layers of plywood together to create internal webbing. This distributes the weight evenly, pressing the vanity against the wall like a cantilever for a rock-solid installation.

Adding Ebony Inlays for Contrast

For a touch of elegance, I incorporated ebony inlays into the design. After sketching the shapes on paper, I used spray adhesive to attach the template to the ebony and cut them out on the bandsaw.

To ensure a perfect fit, I secured the inlays with double-sided tape, traced them with a marking knife, and then carefully chiseled out the recesses, working from the center outward to preserve clean edges. After gluing them in, I left about an eighth of an inch proud, then planed and sanded them flush.

Finishing Touches

To protect the wood and enhance its natural beauty, I applied spar varnish—a durable, water-resistant finish—to both the vanity top and backsplash.

Final Thoughts

This walnut vanity was a labor of love, blending traditional woodworking techniques with creative problem-solving. From filling natural imperfections with epoxy to engineering a sturdy French cleat system, every step was about balancing aesthetics and functionality. The result? A stunning, one-of-a-kind piece built to last.
