Thicker Is Better: Why 3cm Slabs Are Revolutionizing Countertop Design in 2025
The countertop industry is experiencing a significant shift toward thicker slabs, with 3cm countertops making a strong return in 2025, with a standard 3cm slab preferred for its durability and bold presence, creating a more substantial and luxurious look. This trend represents a departure from the ultra-thin profiles that dominated recent years, as homeowners increasingly prioritize durability, visual impact, and long-term value in their kitchen investments.
The Rise of Thicker Countertops
Granite countertops with a 3cm thickness are currently considered to be the industry standard, with thicker slabs now preferred by many homes due to their increased attractiveness. The movement toward substantial thickness isn’t just about aesthetics—it’s driven by practical considerations that make thicker slabs a superior choice for today’s busy kitchens.
Thick-slab porcelain countertops are gaining momentum in 2025, with their substantial presence and luxurious appeal adding drama and depth to kitchen spaces, creating a sense of opulence and grandeur. This trend extends beyond traditional stone materials, influencing the entire countertop market.
Why Thicker Slabs Are Becoming the New Standard
Enhanced Durability and Strength
The primary advantage of thicker countertops lies in their superior structural integrity. Thicker granite slabs, such as the 3cm and 5cm options, are inherently more durable and less prone to cracking or breaking, with thicker slabs recommended for high-traffic areas or spaces prone to heavy use. This enhanced durability translates to better performance in busy kitchens where countertops endure constant use.
The thicker profile of 3cm quartz provides exceptional resistance to chipping, cracking, and impacts, ensuring a countertop that stands the test of time, with increased thickness contributing to improved heat resistance. For homeowners seeking the best countertops for their kitchen renovation, thickness has become a crucial consideration for long-term performance.
Reduced Installation Complexity
Thicker slabs no longer need to be strengthened with plywood during installation and require less labor, while 2cm thickness granite countertops often take extra effort since they frequently need certain slabs to be thinned out and require reinforcement during installation to prevent drooping or cracking. This simplification in the installation process makes thicker slabs more appealing to both contractors and homeowners.
Most fabricators, architects, and designers prefer countertops to be 3cm thick because it offers the most durability, color options, and flexibility in size, and can be installed directly on top of the cabinets without plywood support.
Superior Aesthetic Appeal
The visual impact of thicker countertops cannot be understated. A thicker countertop can look more luxurious, providing the substantial presence that today’s homeowners desire. A thicker granite slab enhances the overall look of your countertop, providing a more substantial and elegant appearance, with 3cm thickness offering a more impressive visual impact and adding depth and grandeur for a sophisticated and upscale feel.
Edge detail for countertops is being considered more, with detailed edging especially where a thicker worktop is being used to create a showpiece. This allows for more elaborate edge profiles and custom detailing that wasn’t possible with thinner materials.
Practical Benefits for Modern Kitchens
Better Support for Large Overhangs
Thicker stone facilitates options like eliminating seams or creating significant overhangs, with whether you want to eliminate seams or create a significant overhang, thicker stone facilitating these options. This is particularly important for kitchen islands and breakfast bars where extended overhangs are desired for seating areas.
For large countertop overhangs, fabricators may recommend the thicker option, ensuring structural integrity without the need for additional support brackets that could interfere with seating or storage.
Outdoor Applications
For exterior use, if you are planning to have your countertop installed outside, like for an outdoor kitchen or BBQ top, a 3cm thick countertop is recommended, as due to temperature changes and weather, your countertop may expand and contract over time, with a thicker countertop material reducing this risk and holding up better in the long run.

The thicker the slab, the higher the cost of the material, with usually a 20% to 40% difference in the cost of materials between a 2cm and 3cm slab. However, the added cost can be justified by the increased durability of thicker granite, with it being important to consider this durability when planning your budget.
