Removing tile floor under kitchen cabinets is often the first critical step in a major kitchen remodel. This task requires more than just a strong back; it demands precision, the right tools, and a methodical approach to avoid damaging surrounding surfaces. Whether you are planning to install new cabinets or refinish the existing ones, exposing the subfloor is essential, and doing it correctly saves you from costly mistakes later in the project.
Preparing for the Demolition
Before a single tile shatters, preparation is the most overlooked yet vital phase of this process. You cannot simply swing a hammer without safeguarding the kitchen’s functionality and structural integrity. Proper prep work transforms a chaotic mess into a manageable project, ensuring the space remains safe for everyone involved.
Clear the Space Completely
- Remove all items from the kitchen, including small appliances, cookware, and food items.
- Take down any dish racks, cabinet doors, or hardware hanging on the walls.
- Move large appliances like the fridge and oven out of the way to create a clear working zone.
Protect Adjacent Areas
Tile demolition creates significant dust and debris, and cabinets are often the most vulnerable targets. To prevent chipping the finish or scratching the surfaces, you must shield them effectively. This protection ensures your existing cabinetry looks as good as new once the floor is gone.
Shut Off Utilities
Locate the water supply lines running to the sink and double-check that the electricity to the under-cabinet lighting is cut off. While you may not be working directly on plumbing or wiring, accidental contact is a real risk during floor removal. Cutting power and water eliminates the potential for dangerous shocks or water leaks.
The Right Tools for the Job
Using the correct equipment is the difference between a clean removal and a smashed-up disaster. While a basic toolkit might seem sufficient, specific tools are designed to give you control. Investing time in selecting the right saws and removal tools prevents the need for tedious rework.
| Tool | Purpose |
|---|---|
| Reciprocating Saw | Best for cutting through tile and grout lines near the cabinet bases. |
| Angle Grinder with Diamond Blade | Ideal for making precise cuts in the tile without disturbing the subfloor. |
| Tile Chisel and Hammer | Used for manually breaking up tiles after they have been scored. |
| Shop Vacuum | Essential for clearing dust and debris from tight cabinet corners. |
Step-by-Step Removal Process
With the space cleared and tools in hand, you can begin the physical removal. The goal here is to remove the tile down to the plywood or concrete subfloor without disturbing the structural integrity beneath the cabinets. Working carefully at the edges prevents the tiles from cracking inward and getting trapped under the cabinet weight.
Step 1: Cut the Grout Lines
Use your angle grinder or a oscillating multi-tool equipped with a diamond blade to slice through the grout lines running alongside the cabinet kick plates. This scoring action allows the tiles to break cleanly along the seam rather than cracking randomly. Make deep cuts along the entire length of each cabinet row.
Step 2: Break the Tiles
Target the center of the tile with a heavy rubber mallet. A direct hit usually causes the tile to shatter into manageable pieces. If the tiles do not break easily, go back with the grinder to deepen the cuts you made earlier. Remember to wear safety goggles to protect your eyes from sharp shards.
Step 3: Remove Debris
Once the tiles are shattered, use a broom and dustpan to sweep the bulk of the debris. Follow this immediately with a shop vacuum to suck up the fine dust and small pieces stuck in the corners. It is crucial to get the area as level as possible before installing new flooring or tightening the cabinets.
Managing Cabinet Legs and Supports
Kitchen cabinets rarely sit directly on the floor; they rest on legs or a toe kick. Removing the tile often changes the height alignment or stability of the cabinets. You must adjust these supports carefully to ensure the cabinets sit level and secure. Ignoring this detail can lead to uneven countertops or doors that won't close properly.
Adjusting Cabinet Height
If you remove a thick layer of tile, the cabinets will be higher off the ground than intended. Most modern base cabinets feature adjustable feet. You can turn these feet clockwise to lower the cabinet or counter-clockwise to raise it. Use a level tool on the top of the cabinet to ensure it is perfectly aligned before locking the adjustment in place.
Securing the Structure
After leveling, verify that the cabinets feel solid when pushed gently. If there is any wobbling, use wood shims behind the cabinet to stabilize it against the wall. Once stable, secure the cabinet to the adjacent units and then to the wall studs with screws. This step is critical for preventing the cabinets from detaching from the wall over time.
Finishing the Floor Area
With the old tile removed and the cabinets adjusted, the area is ready for the new flooring material. Whether you are installing hardwood, vinyl, or new ceramic tile, the subfloor is now exposed and ready for the next phase. Taking the time to ensure the subfloor is clean and level will determine the final smoothness and longevity of your new kitchen floor.
Preparing the Subfloor
Inspect the subfloor for any nails, screws, or splinters left from the old installation. Sand down any rough patches and fill any gaps or holes with wood filler. A smooth, flat surface is required to prevent hollow spots or squeaks in the new flooring. Sweep the area thoroughly to remove any remaining dust before proceeding with installation.
Transition Planning
Consider how the newly exposed area will connect to the rest of the kitchen. You might need to install a transition strip where the kitchen floor meets the tile in the hallway or adjacent room. Planning for these transitions now ensures a cohesive look throughout the entire space, creating a polished finish that ties the room together.
