Installing Base Cabinets Into Concrete Floors: A Step-by-Step Guide

Installing a base cabinet in concrete isn’t as difficult as it might sound. With a few basic tools and components you can have your new cabinets securely and safely attached in just a few hours.

Begin by measuring where you’d like the cabinet(s) to be placed. Then use a pencil to create a template of the cabinet’s outline on the floor (if you don’t have a lot of room to work with, bring in one cabinet at a time). Once you have the template set, move the cabinet out of the way and measure according to the template. Then capture 2/3 of the width on each end of the template for the overall base size of the cabinet, and mark that down.

Create a base to install the cabinets on by cutting two 2×4 boards according to the measurements you marked. Place the 2x4s 3/4 inch inside the marked area and make another mark at this spot- this will be your pilot hole where the concrete anchors will be installed. Pre-drill 3 holes in each 2×4 then use a T-square to measure out the corners, so the cabinet will sit on a straight line when secured.

Once everything has been measured and marked, you can begin the installation process. Use a hammer drill to make pilot holes in the concrete which correspond to the pilot holes you created in the 2x4s. This step is critical because it will ensure your cabinet is anchored securely in the concrete- make sure the holes are at least 2 inches deep.

You can then use the concrete anchor screws to secure the base for the cabinet onto the concrete. To attest the cabinets, position them on top of the base and use wood screws to attach the cabinets to it along the interior bottom panel. Use shims if necessary to create a level surface for the other cabinets.

Finally, to give a neat and finished look to your installation you can install decorative trim to cover the base. Baseboard trim is a great option, however you may need to cut it to size depending on the length of your base. If you’re wanting something larger, toe kick boards can give more coverage when attached to the base. These can be attached with a drill and wood screws, then filled in with putty. Alternatively, a strong adhesive can also be used but be aware of the weakening effect humidity has on adhesive bonds- especially for bathrooms, basements and laundry rooms.

With these steps, you now have the knowledge to confidently install a base cabinet in concrete. In just a few hours you’ll have secure and great looking cabinets installed. So don’t be intimidated by the thought of undertaking cabinet installations- go ahead, get your tools and get ready to install!
