How to Install Base Cabinets on Concrete Floor?

After gathering the necessary tools and materials, It’s time to go on the step-by-step guide. I have explained some simple steps to install base cabinets on concrete.

For perfect installation and to avoid any damage, read all the steps carefully. Make sure the level of the concrete floor is perfect to avoid the gap between cabinets and floor.

Measure and Plan on Concrete

Before you work on concrete, measure the dimensions of the base cabinets. Measure the width and length with extreme care, if you have inaccurate measurements, you can’t install the base cabinets perfectly.

Draw the dimensions on the concrete floor using a pencil or chalk. This visual plan helps you position the cabinets accurately during installation.

Use a level to ensure the floor is even or not. An uneven or sloping floor causes gap between cabinets and floor. This becomes a reason for instability of the base cabinets after installation.

Prepare Concrete for Installation

By using a table saw, cut two 2-by-4 wooden boards, a length of 2/3 of the width of your base cabinets. In other words, If the width of the base cabinets is 24 inches, then cut two boards of 16 inches in length for each base cabinet.

Place 2-by-4 board on concrete, 3/4 inch inside the lines you have drawn. The 3/4 inch is necessary for the adjustment of the side walls of the base cabinets. The sides of the base cabinet will be placed on the outside edge of the board.

Now place the cleat or T-Shape with the inner side of the board to attach this board to the concrete. Drill 4-inch concrete anchoring screws in the cleat to the concrete and fasten the cleat with the board by screwing them for a strong and reliable attachment to the concrete.

Place Base Cabinets on Concrete

Now place the corner or side cabinet first and then the other base cabinets. Place the wall or sides of the base cabinets adjacent to the outside of the board, leveled with the concrete.

After adjusting the corner base cabinet, place the center base cabinets and check the level of all base cabinets. If the cabinets are not leveled with each other, put some shims beneath the base of the cabinets to level them.

Once all the cabinets are in place, secure them together using cabinet screws before attaching them to the concrete floor. These screws provide a strong and reliable attachment.

Attach Base Cabinets to Concrete

Before attaching base cabinets to the concrete floor, use safety goggles and ear protection. Now fasten the base cabinets to the concrete by screwing them into the board.

Do this process for all the base cabinets. Make sure the base cabinets are leveled and aligned correctly. If the cabinets are not leveled then there must be a gap between cabinet and floor.

Finishing Touches

Now base cabinets are installed on the concrete floor. The last step is to attach cabinet doors and drawers. Make sure the doors are aligned correctly. If doors are not aligned, then it’s crucial to fix a warped cabinet door to give an aesthetic look.

Check that all cabinet doors and drawers open and close smoothly. For installing the countertop follow the manufacturer’s guide to avoid any damage.
