When planning a kitchen renovation or new build, one of the most important decisions revolves around the benchtop. Beyond the choice of stone type or colour, thickness plays a major role in shaping the overall style, functionality, and durability of your kitchen. In Perth, stone benchtops are available in standard thicknesses such as 20mm, 40mm, and 60mm, each offering its own unique appeal.
We’ve worked with countless homeowners across Perth, and we know that the thickness you choose isn’t just about looks—it can influence practicality, maintenance, and even the perception of space in your kitchen. Let’s break down each option to help you find the right fit.
20mm Benchtops: Sleek and Minimalist
A 20mm benchtop is the thinnest option available and has become a favourite for homeowners who want a clean, modern aesthetic. The slim profile adds a sense of elegance and simplicity to contemporary kitchens. Because of its refined look, 20mm is often paired with handleless cabinetry and minimalist design concepts.
From a practical perspective, 20mm stone is lightweight compared to thicker options, which makes it easier to install. This thinner style can also visually open up smaller kitchens, creating an airy and uncluttered atmosphere.
However, while durable, 20mm surfaces may not feel as substantial as thicker options. Designers sometimes recommend mitred edges to create the illusion of greater thickness without the added weight. This clever use of stone design shows how the right detailing can transform even a simple material choice into a defining element of your kitchen’s personality.
40mm Benchtops: The Balanced Choice
For many Perth households, 40mm benchtops strike the perfect balance between modern minimalism and bold presence. They deliver a more substantial look than 20mm while avoiding the weight and cost associated with 60mm slabs.
Functionally, 40mm provides excellent durability for busy kitchens that endure heavy daily use. This thickness also allows for greater design versatility, as it complements both contemporary and traditional kitchens. Many homeowners find 40mm to be the “safe middle ground” that pairs seamlessly with most cabinetry and splashback styles.
On the aesthetic side, 40mm stone adds dimension and definition without overwhelming the overall design. It is often chosen by households looking for surfaces that don’t just look good but also stay easy to care for in the middle of everyday cooking and entertaining.
60mm Benchtops: Bold and Luxurious
If your goal is to create a statement kitchen, a 60mm benchtop delivers immediate impact. This thickness exudes luxury and strength, making it the go-to choice for those who want their kitchen to feel grand and substantial.
Visually, a 60mm benchtop becomes a focal point. It works beautifully in large kitchens with spacious layouts, often paired with waterfall edges or expansive islands. In open-plan living spaces, a thicker benchtop draws attention and creates a sense of permanence.
Of course, 60mm benchtops are heavier and generally more expensive than thinner options. Installation may require additional structural support, particularly with large spans. Still, the investment pays off for homeowners who value a commanding, timeless kitchen feature. Just as with choosing the right stone colour or finish, selecting a thicker profile reflects the desire to make a bold, lasting statement in the heart of the home.
Practical Considerations When Choosing Thickness
While aesthetics often lead the conversation, practical factors are equally important. Weight, cost, and kitchen size all influence which thickness will work best in your home.
- Kitchen Size: Slimmer 20mm tops can help smaller kitchens feel more open, while larger spaces can handle the drama of 60mm.
- Cabinetry Strength: Heavier benchtops may require stronger cabinetry and reinforcements to ensure safe installation.
- Budget: Thicker benchtops generally cost more due to the added material and installation requirements.
- Lifestyle Needs: Families who cook frequently may prefer the sturdiness of 40mm or 60mm, while occasional cooks might opt for 20mm for its lighter, modern appeal.
Considering your lifestyle and kitchen design together will guide you to the thickness that not only looks good but also performs well for years.
Matching Thickness to Style
Your personal taste and design preferences are just as crucial as functionality. Minimalist kitchens often lean toward 20mm, where clean lines and simplicity take centre stage. Transitional kitchens—those blending classic and modern influences—work well with 40mm. Meanwhile, luxury or statement kitchens almost always shine brightest with 60mm stone.
Think about how the benchtop interacts with other elements such as cabinetry colour, flooring, and lighting. For example, lighter 20mm tops can enhance natural light and make smaller spaces feel more expansive. In contrast, a thick 60mm benchtop in darker tones can ground a space, adding richness and character.
Finding the Perfect Fit for Your Kitchen
Choosing between 20mm, 40mm, and 60mm stone benchtops ultimately comes down to your kitchen’s design, practical needs, and the atmosphere you want to create. Each thickness offers its own strengths: the elegance of 20mm, the balance of 40mm, and the statement power of 60mm.
