Floating floors have become a popular choice for homeowners seeking a DIY-friendly installation method and the ability to upgrade existing spaces without extensive demolition. The core question of whether these floors can be installed directly under cabinets hinges on the specific type of floating system used and the construction of the cabinets themselves. Understanding the interaction between the floor's expansion needs and the fixed position of cabinets is essential for a successful and long-lasting renovation.
Understanding Floating Floor Mechanics
Unlike traditional glued or nailed flooring, floating floors do not adhere to the subfloor. Instead, they lock together in a puzzle-like fashion and rely on the force of expansion to stay together. This design is intended to allow the floor to move slightly in response to changes in temperature and humidity. The planks typically expand across the width of the room, pushing against walls and other fixed objects. This fundamental principle is the primary reason for careful planning when installing cabinets on top of this surface.
The Cabinet Factor
Cabinets are heavy, permanent fixtures that anchor down the flooring directly beneath them. Once installed, the flooring plank located directly beneath a cabinet cannot expand or contract freely in the transverse direction. The cabinet legs act as a barrier, locking that specific plank in place while the rest of the floor continues to move around it. This disparity in movement is the central issue installers must address to prevent future problems.
Potential Risks of Installation
Ignoring the expansion gap requirement beneath cabinets can lead to several issues down the line. The most common risk is buckling or warping of the floorboards. As the floating floor attempts to expand during humid seasons, the restricted movement under the cabinet creates pressure. This pressure has nowhere to go but up, potentially causing the planks to buckle or creating a noticeable ridge where the cabinet meets the wall.
Another risk involves the integrity of the cabinet itself. If the flooring is forced to expand but is completely restricted, the pressure can translate into the cabinet structure. You might observe the cabinet doors begin to stick, the frame to become misaligned, or in severe cases, the cabinet foot to become compromised. Ensuring the floor remains flat and stable is crucial for the longevity of both the floor and the cabinetry.
Best Practices for Installation
To avoid these complications, it is standard practice to install the floating floor first, leaving the necessary expansion gap around the perimeter of the room. Once the floor is fully secured and acclimated, the cabinets can be installed. This method ensures the floor is free to move up to the base of the cabinets without restriction. The weight of the cabinets will then hold the flooring firmly in place, eliminating any gap between the cabinet base and the floor.
| Installation Order | Process | Benefit |
|---|---|---|
| Floating Floor First | Install floor across the entire room, leaving a 10mm gap under cabinets. | Allows full expansion and contraction of the floor. |
| Cabinets Second | Place cabinets on top of the installed floor, squaring them to the walls. | Distributes floor weight evenly and locks the planks beneath in place. |
Material-Specific Considerations
Not all floating floors are created equal, and the material choice impacts the installation dynamics. Laminate flooring is highly susceptible to expansion and contraction, making adherence to the floating method strict. Engineered hardwood is a more stable option but still requires movement gaps. Luxury Vinyl Plank (LVP) is often the most forgiving due to its flexible nature and stronger locking mechanisms, but professional installers still recommend the same sequence of cabinets down to ensure a flawless finish.
Ultimately, installing floating floors under cabinets is not only possible but is often the recommended sequence for a flawless result. By prioritizing the floor installation and respecting the expansion gap during the cabinet placement, you ensure the floor remains flat and stable for years to come. This careful planning protects your investment and ensures the structural integrity of both your flooring and cabinetry.
