How to Build Wooden Bar Countertops

Measure the distance for the bar. Remember that the bar piece must extend over the cabinets. Add the desired overhang on both sides of the bar. For the seating area, the average overhang is typically 12 inches. There should also be at least a 3-inch overhang on the other side of the countertop.

Take your measurements to a lumber yard or building supply store and have a solid piece of wood cut to your desired size.

Round off the edges of the counter, including the corners, with an edger.

Sand the entire countertop with an orbital sander, going with the grain. You’ll want to start with a 90-grit and work up to a 250-grit disc. This process removes all the splinters and imperfections from the wood and gives the wood a smooth feel.

Brush on your desired color of stain with a sponge brush. You’ll only need to stain the top and sides of the countertop. Even if you prefer the look of natural wood, a stain is advisable to bring out the wood’s grain. Wipe away any excess stain and allow the surface to dry for the manufacturer’s recommended time.

Finish off the wood with either a food-grade sealer or food-grade mineral oil with a paintbrush. A sealer is ideal if the bar will only be used for serving food. If the bar will be used for preparing food, mineral oil is best.

Set the bar into position, and secure it to the countertop with L-brackets placed on the inside of the cabinetry. If your overhang is more than 12 inches, you may also want to consider using a table leg on both ends of the bar for added support.
