Porcelain Slabs Sydney

Porcelain slabs have become one of the most sought-after surfacing materials in contemporary Australian homes and commercial spaces. They replicate the natural beauty of marble, stone, and concrete with a surface that handles daily use without sealing, specialist cleaning, or ongoing maintenance. At Avant Stone, our porcelain slab collection spans a wide range of designs, finishes, and thicknesses, giving Sydney and Newcastle homeowners, designers, and builders a genuine choice for every application.

Whether you’re planning a kitchen splashback, a feature wall, a bathroom vanity, or a full kitchen benchtop, our porcelain slab range includes 6mm, 12mm, and 20mm options to suit the specific demands of your project. Visit our showrooms in Greenacre or Beresfield to see the full collection at full slab size, or speak with our team today to get advice tailored to your project before you buy porcelain slabs in Sydney.

Why Choose Porcelain Slabs?

A Surface That Needs No Sealing

One of the most practical advantages of porcelain slabs is the complete absence of any sealing or ongoing treatment requirements. Unlike natural stone, which requires periodic resealing to maintain its protective qualities, porcelain is fully non-porous straight from installation. Stains, moisture, and bacteria cannot penetrate the surface, which means the finish you see on day one is the same finish you’ll have in ten years.

Available in 6mm, 12mm, and 20mm

Our porcelain slabs range covers three thickness options, each suited to specific applications. The 6mm range is designed for vertical surfaces, including kitchen splashbacks, feature walls, and bathroom wall cladding. The 12mm range suits kitchen benchtops, bathroom vanity tops, flooring, and stairs. The 20mm range is our thickest option, recommended for heavy-use benchtops, outdoor alfresco kitchens, and waterfall islands where edge strength and visual presence matter. Our team can walk you through which thickness is right for your specific project.

Wide Range of Designs for Every Interior

Our large-format porcelain slabs collection covers the full spectrum of contemporary Australian design. From the dramatic black veining of Classic Marquina and Noir Laurent to the soft, luminous whites of Antique White and Invisible Select, and the warm naturals of Honey, Bone, and Corchia Gold, there is a design to suit every interior direction. Advanced printing technology allows us to deliver high-definition patterns that accurately replicate the aesthetics of natural stone, wood, and concrete with exceptional consistency across large-format slabs.

Heat, Scratch, and Stain Resistant

Porcelain slabs are manufactured to handle the demands of busy Australian kitchens and commercial environments. The surface resists scratching from daily use, staining from food, oils, and liquids, and damage from heat exposure. You can place hot cookware on a 12mm or 20mm porcelain benchtop without risk of scorching or marking. For outdoor applications, porcelain also holds its colour and finish under direct UV exposure without fading or deteriorating over time.

Straightforward Installation with Fewer Joins

Large format porcelain panels reduce the number of joins required across any given surface, creating a cleaner, more seamless aesthetic whether you’re cladding a full bathroom wall, installing a kitchen splashback, or laying a feature floor. The 6mm panels are particularly well-suited for installation over existing surfaces in renovation scenarios, reducing the need for full demolition and significantly shortening project timelines.

6mm, 12mm, and 20mm Porcelain Slabs: Which Thickness Is Right for You?

Choosing the right thickness is one of the most important decisions in any porcelain slab project. Each option is engineered for a specific range of applications, and selecting the wrong thickness can affect both the performance and the finished result.

6mm Porcelain Slabs

The 6mm range is designed for vertical surfaces where a slimmer, lighter profile is an advantage. Kitchen splashbacks, bathroom wall cladding, feature walls, and renovation overlays over existing surfaces are all ideal applications. The reduced weight makes 6mm panels easier to handle and install, and in many renovation scenarios, they can be fixed directly over existing wall surfaces without full demolition. For flooring or benchtop applications, 6mm is not recommended.

12mm Porcelain Slabs

The 12mm range is the most versatile option in our collection. It suits kitchen benchtops, bathroom vanity tops, flooring, and stair applications where greater structural strength is required. The additional density provides the surface integrity that horizontal, high-use applications demand, and the thickness reads well on a standard benchtop edge profile. For most Sydney kitchen and bathroom renovations, 12mm is the recommended starting point.

20mm Porcelain Slabs

The 20mm range is our thickest option and is recommended where maximum edge strength and visual presence are priorities. Waterfall kitchen islands, outdoor alfresco benchtops, and heavy-use commercial surfaces all benefit from the additional thickness. The 20mm edge profile reads noticeably more substantial than 12mm and adds a quality finish to any benchtop installation. For outdoor applications in particular, 20mm provides greater resistance to edge chipping and impact over time.

If you are unsure which thickness suits your project, speak with our team at either our Greenacre or Beresfield showroom, and we can advise based on your specific application and design requirements.

Applications and Uses

Porcelain slabs suit a broad range of residential and commercial applications across all three thickness options.

Kitchen Splashbacks: A 6mm porcelain splashback Sydney homeowners choose for its practicality and clean visual result. The surface is non-porous, resists cooking splashes and steam, and covers large areas with minimal joins for a seamless contemporary finish. Our Calacatta Emerald, Grigio Venato, and Classic Marquina designs are particularly popular for splashback applications.

Kitchen Benchtops: For benchtop applications, our 12mm and 20mm porcelain slabs deliver the heat resistance, scratch resistance, and low-maintenance surface that busy kitchens require. The 20mm option suits island benchtops and waterfall edges where the thickness profile is part of the design.

Feature Walls: Porcelain slabs create striking feature walls in living rooms, bedrooms, bathrooms, and commercial interiors. The lightweight nature of our 6mm porcelain panels makes them easier to handle and install across large vertical surfaces without the structural concerns associated with heavier materials.

Bathroom Vanity Tops and Walls: Porcelain’s non-porous surface makes it a natural choice for wet areas. Our 12mm range suits vanity tops, while the 6mm panels work beautifully across shower walls and bathroom feature areas. The surface stays hygienic without any special treatment, making it ideal for bathrooms that need to look good with minimal upkeep.

Outdoor Alfresco Areas: For outdoor kitchens, BBQ benchtops, and poolside surfaces across Sydney and Newcastle, our 12mm and 20mm porcelain slabs are UV-stable, frost-resistant, and impervious to moisture. They hold their colour and finish in full sun exposure without fading, warping, or requiring any protective coating over time.

How to Care and Maintain Your Porcelain Slabs

Regular Cleaning: Wipe surfaces with a soft cloth and warm water for day-to-day maintenance. A mild detergent handles tougher marks without affecting the surface finish. Avoid harsh chemicals, as these can dull the surface over time.

Wipe Up Spills Promptly: Porcelain is non-porous and highly stain-resistant, but wiping spills as they happen prevents residual buildup and keeps surfaces looking their best with minimal effort.

Avoid Harsh Chemicals and Abrasives: Acidic, bleach-based, or abrasive cleaners can affect the surface finish over time. Stick to pH-neutral, non-abrasive products to preserve both the appearance and durability of your slabs.

Use Cutting Boards and Trivets: Porcelain benchtops are highly resistant to both heat and scratches, but using cutting boards and trivets is a sensible habit that protects the surface finish and your knives over the long term.

FAQs about 6mm Porcelain Slabs

What are the main benefits of using 6mm porcelain slabs?

6mm porcelain slabs are lightweight yet durable, with low-maintenance qualities that make them perfect for various applications. They are heat-resistant, stain-resistant, and scratch-resistant, making them ideal for both residential and commercial spaces.

Where are 6mm porcelain slabs typically used?

They are often used as kitchen splashbacks, feature walls, bathroom vanity tops, or wall cladding. Their lightweight nature also suits them for furniture applications and commercial interiors.

Are 6mm porcelain slabs suitable for high-traffic flooring?

6mm porcelain slabs are durable but are better suited for vertical surfaces and light-traffic flooring. For high-traffic areas, we recommend using thicker porcelain slabs, such as the 12mm variety.

Can 6mm porcelain slabs be used for exterior applications?

Yes, 6mm porcelain slabs are suitable for some exterior applications as they are resistant to UV rays, moisture, and temperature changes. However, for high-use outdoor areas such as paving, thicker slabs may be more appropriate.

How do 6mm porcelain slabs compare to 12mm slabs in terms of durability?

While both 6mm and 12mm porcelain slabs are robust, 12mm slabs are stronger and more impact-resistant, making them better suited for flooring and countertops. The lighter 6mm slabs are ideal for wall cladding and splashbacks.

What kind of maintenance do 6mm porcelain slabs require?

Very little maintenance is needed for 6mm porcelain slabs. Use a mild detergent for cleaning, and avoid harsh chemicals that may scratch your porcelain slabs.

Is professional installation required for 6mm porcelain slabs?

Although 6mm porcelain slabs are easier to handle than thicker slabs, professional installation ensures precise cutting, proper adhesion, and a flawless finish. We recommend consulting a skilled installer to achieve the best results.
