How To Install a Butcher Block Countertop

Butcher block countertops add charm to your kitchen while providing a durable and functional surface. In this guide, we’ll walk you through the process of installing a butcher block countertop, from selecting the right wood to applying the final finish. This Old House carpenter Nathan Gilbert demonstrates the installation process in the video above.

Choosing the Right Butcher Block

Gilbert installed an unfinished maple butcher block countertop manufactured by Hardwood Reflections. He ordered an 8′ by 4′ section. When selecting your own butcher block countertop, consider the following factors.

Wood Type

Gilbert uses maple, a popular choice for butcher block countertops because of its hardness and durability. Other options include teak, mahogany, oak, and walnut. Each wood offers a unique color, grain pattern, and hardness. 

Thickness and Size

Butcher block countertops typically come in thicknesses ranging from 1 1/2–2 1/2 inches. The standard depth is 25 inches, although you can order custom sizes. Measure your cabinets accurately and account for any desired overhang before buying.

Preparing to Install Butcher Block Countertops

Proper preparation is key to a smooth installation process. Take these steps before starting your project.

Remove Existing Countertops

To remove your existing countertops, you may need to disconnect and move appliances. Follow these steps:

1. Turn off the power to the garbage disposal and disconnect it.
2. Turn off and disconnect any water lines going to the sink.
3. Remove any clips or screws holding in appliances such as dishwashers.
4. Unplug and move stoves, refrigerators, and any other appliances.

Next, remove any clips or screws securing the old countertop. You may need to break a silicone seal, as Gilbert demonstrates in the video. Carefully pry the countertop off, and be mindful of any backsplash.

Measure and Cut

Measure carefully for a proper fit, and remember to account for any overhang. Before cutting the new countertop, identify which side of the butcher block should face up and which side should face down. Gilbert used a circular track saw for precision. If joining two pieces, create a mortise using a Forstner bit and chisel, then use a joint connector for a seamless look. Gilbert used Gorilla brand wood glue and joint connectors to secure the two sections together.

Prepare the Sink Area

Use a template to mark the cutout area for a new sink—some sinks come with their own template, so be sure to check the packaging. Gilbert uses a circular saw to cut the hole with a piece of strapping across the butcher block to prevent the cutout from falling.

Countertop Installation Process

Now, you’re ready to start installation. Here’s what to do.

Dry Fit

Before securing the countertop, do a dry fit to check that everything aligns properly. This is your opportunity to make any necessary adjustments.

Secure the Countertop

Use wood screws and glue to attach the butcher block to the cabinets. Be careful not to over tighten the screws, as this can split the wood.

Install the Sink

Once the countertop is secure, install your sink according to the manufacturer’s instructions. We recommend having a licensed plumber connect the water lines and disposal.

Apply Finish

Apply a food-safe finish to protect your butcher block. Gilbert recommends a mineral oil, which is safe for food contact. He used food-grade cutting board oil manufactured by Howard Products. Here’s how to apply it:

1. Pour a generous amount of oil onto the surface.
2. Use a squeegee to spread it evenly.
3. Buff the oil into the wood using a clean cloth.

Apply two or three layers initially, allowing each to soak in before applying the next. After that, reapply monthly for ongoing protection.
