Installing Ready-to-Assemble (RTA) Cabinets: A Step-by-Step Guide

Installing ready-to-assemble (RTA) cabinets can be a smooth and rewarding process with the right preparation and tools. These cabinets offer an affordable and stylish solution for homeowners looking to renovate without compromising quality. So, how do you go about installing kitchen cabinets properly?

Essential Tools for Cabinet Installation

Tape Measure and Pencil
Accuracy is everything. Use a tape measure to take exact dimensions of your space and mark cabinet placement on the wall with a pencil. The pencil allows for easy adjustments without damaging surfaces, ensuring precise positioning every time.

Clamps
Clamps are crucial for keeping cabinet parts aligned and stable while fastening. They hold components tightly in place, allowing for clean and secure installation.

Ledger Board
A ledger board acts as a temporary support for upper cabinets. Mounted along your marked level line, it bears the weight of the cabinets during installation, allowing for safe and accurate placement.

Stud Finder
This tool helps you locate wall studs hidden behind drywall. Anchoring cabinets into studs is essential for stability and long-term durability.

Level
A level ensures your cabinets are installed straight and true—horizontally and vertically. Proper leveling is vital for both function and appearance.

Shims
Shims are thin, wedge-shaped pieces used to adjust cabinet height and fill small gaps. They are especially useful when working with uneven floors or imperfect walls.

Drill and Drill Bits
A reliable drill and the correct bits are essential for creating pilot holes and driving screws. They make installation faster, easier, and more efficient.

Nail Gun
Use a nail gun to attach finishing trim, such as scribe molding, toe kicks, shoe molding, or crown molding, for a clean and polished look.

Hardware Jig
A hardware jig ensures perfect, uniform alignment when installing cabinet knobs and pulls, saving time and avoiding mistakes.

Caulk Gun (Color-Matched)
Fill any small gaps or nail holes with color-matched caulk for a seamless finish that blends perfectly with your cabinets.

These tools, combined with proper planning and careful execution, make installing RTA cabinets a project well within reach—even for beginners. By following step-by-step guidance and taking your time, you can confidently transform your kitchen with beautiful, professional-looking results.

How to Install Cabinets:

Let’s examine each step so you are 100% equipped with the knowledge needed to install cabinets. After you review this list, you will discover how to install wall cabinets, base cabinets, and drawers.

1. Take Kitchen Measurements

Start by carefully measuring the kitchen area. Use a pencil and tape measure to note measurements throughout the room. Measure from top to bottom. Be sure to mention any obstructions from windows to doorways and electrical outlets. Additionally, use a stud finder to mark where any studs are present to attach the cabinetry to offer more support.

2. Protect Installation Area

Be thorough in safeguarding floors and surrounding surfaces from scratches or damage during installation. Start by carefully laying down a tarp or protective plastic sheeting. Next, ensure all surfaces are completely free of dust and debris by cleaning them meticulously before beginning any work.

3. Utilize a Ledger Board for Easier Installation

Install a ledger board—a horizontal wooden strip secured to the wall at the desired height of your kitchen cabinets. This support tool simplifies the installation process by providing a stable, temporary base to hold the cabinets in place. Always make sure the ledger board is firmly anchored to the wall to prevent any movement that could lead to accidents or damage. Additionally, use shims as needed to ensure the cabinets are level throughout the installation.

4. Check Cabinets

When your cabinetry arrives, take the time to carefully inspect all materials. This ensures everything is in good condition and that your order is complete. If you have any questions or concerns about the process, our team is ready to assist you.

Pro Tip: Organize Your Hardware – Sort all hardware into labeled Ziploc bags or Tupperware containers. This simple step keeps everything organized and easily accessible throughout the cabinet installation.

5. Install Wall Cabinets

Start by drawing a straight horizontal line on the wall to mark where the bottom of the wall cabinets will be positioned—typically 54 inches from the floor. This measurement accounts for an 18-inch backsplash above standard 36-inch base cabinets. Use a stud finder to locate and mark the wall studs, then temporarily attach a ledger board along the marked line to support the weight of the cabinets during installation.

Begin with the corner wall cabinet. Carefully position it, ensuring it is level and plumb, then secure it to the wall studs using screws. Continue installing the remaining cabinets one by one, fastening each to the adjacent cabinet and checking for level alignment as you go. Make any necessary adjustments to maintain a consistent and accurate fit.

Pro Tip: Label Everything – If you need to pause your installation, label each cabinet part and piece of hardware with its intended location. This will make it much easier to resume the project without confusion.

6. Install Base Cabinets

When installing base cabinets, begin in a corner and use shims as needed to ensure the cabinets are perfectly level and even. Secure each cabinet to the wall studs by driving screws through the back panel into the studs. As you move to adjacent cabinets, use clamps to hold them tightly together, then drill and screw through the side panels to join them securely.

Once all base cabinets are installed and aligned, remove any temporary supports. Complete the installation by adding finishing touches such as trim, toe kicks, and hardware to give your kitchen a polished, professional look.

7. Add Doors and Finishing Touches

After all the cabinets are securely installed, it’s time to add the finishing touches. Attach the cabinet doors and gently set any finishing nails in place using a hammer for a clean, seamless look. Once everything is in position, step back and enjoy the transformation of your new kitchen cabinets.

Pro Tip: Install hardware last – Wait until all doors and drawers are in place before attaching handles or knobs to ensure perfect alignment and placement.
