What Is the Thickest Laminate Flooring?: Exploring Maximum Laminate Flooring Thickness for Durability & Comfort

Laminate flooring has transformed U.S. homes with its durability, accessibility, and easy DIY installation. Whether you're outfitting a bustling family room or a cozy home office, the thickness of your laminate plays a significant role in comfort, sound insulation, and overall longevity. So, what is the thickest laminate flooring available on the market?

Based on industry data from Houzz Design Insights 2025 and my own years working as a senior interior designer, laminate flooring thickness typically ranges from 6mm to 12mm. But for those seeking the thickest, most solid feel underfoot, some manufacturers offer premium options up to 15mm. These super-thick laminates balance resilience with a luxurious, wood-like finish.

Choose the Right Tools

Selecting laminate thicker than 12mm is more than just picking the sturdiest plank. You'll need specific installation tools for heavier boards, such as upgraded underlayment and reinforced transition strips. Homeowners often start planning with a home layout tool to visualize how thicker flooring will impact the elevation of doors and baseboards.

Speed Up Workflow

While thicker laminate can be harder to cut and maneuver, advances in installation systems—like click-and-lock mechanisms—make the workflow more manageable. I recommend prepping with a digital floor plan creator to estimate square footage and waste reduction, especially when factoring in the added height of thicker planks.

Case Studies & Real Examples

Last fall, a family in Chicago upgraded their busy kitchen with 14mm commercial-grade laminate. Despite its heft, installation was a breeze using modern jigs and well-placed underlay. The result? Enhanced footfall quietness and a noticeable, authentic wood feel — a favorite among guests. According to Statista 2025, over 30% of U.S. homeowners now opt for laminates 10mm or thicker in high-traffic spaces for these exact advantages.

Budget & Time Planning

Understandably, thicker laminate comes with a higher price tag and may need a bigger installation window. While standard 8mm planks often cost $1–$3 per square foot, the 12–15mm range pushes closer to $4–$6 per square foot. The investment pays off through improved durability and sound insulation, reducing the need for frequent repairs or replacements. It's smart to account for these costs upfront during your planning, as upgrades to underlayment and trims are likely needed to support thicker boards.

Common Mistakes & Fixes

A mistake I frequently see: forgetting about stair nosings or transition strips. Thicker laminate requires custom-fitted trims and careful measurement at thresholds, or you risk uneven surfaces and tripping hazards. Always test fit the planks with all trims before final installation, and use a room planner to preview any elevation changes digitally first.
