Imagine planning your kitchen renovation and discovering that your chosen white quartz benchtop is now banned due to toxic silica dust.
With Australia’s new engineered stone ban, homeowners are rightly asking, “What’s the safest and durable benchtop for my kitchen?”
So, this guide compares the top alternatives; silica-free engineered stone, porcelain slabs, and natural stone. We’ll cover the health context, key features, pros/cons, pricing and maintenance of each, so you can feel confident about your best kitchen benchtop material choice.
Keep reading to learn which kitchen surface is right for you.
Silica-Free Benchtops | Health-Focused Alternative
Silica-free engineered stone is a man-made benchtop material formulated without crystalline silica (quartz).
It uses alternative binders and aggregates so it looks and feels like quartz stone but without the hazardous silica dust during cutting and polishing. This shift arose because traditional quartz-based benchtops have been linked to silicosis from fine silica dust in fabrication.
In Australia, the manufacture and installation of high-silica engineered stone was banned in July 2024, making silica-free stone the new norm for kitchen benchtops in Perth.
How It’s Made: These surfaces are made from mixes of recyclable materials, resins and natural minerals (but no silica). A recent innovation is Quantum Zero (Essastone), a high-recycled-content quartz alternative. These products mimic quartz in hardness and appearance. They come in consistent, uniform colours and patterns.
Key Features:
Zero crystalline silica – no quartz binder means no toxic dust when cutting or polishing.
Uniform look – consistent colour/pattern (no natural veining variations).
Non-porous & hygienic – very low absorption; stains and bacteria can’t hide.
Durable – scratch- and stain-resistant (comparable to quartz).
Recycled/Eco-friendly – many are made with high recycled content.
Heat caution – generally heat-resistant but can scorch (always use trivets).
Medium weight – heavier than laminate but usually similar to quartz; install with standard tools.

Porcelain Benchtops | Ultra-Durable, Low-Porosity Performer
Porcelain benchtops are very large ceramic slabs made by sintering fine clays, feldspar and minerals under extreme heat. The result is an ultra-dense, fine-grained, low-porosity ceramic panel.
Finishes & Fabrication: Porcelain is essentially baked at over 1200°C, which fuses the particles together in a water-tight, rock-hard surface. These slabs can be polished glossy, honed matte, textured or even leathered, and advanced printing techniques let them mimic marble, concrete, wood or any look.
Common slab sizes are very large (up to 3.2m x 1.6m) and fairly thin (usually 6–12mm for countertops). The thin profile allows ultra-sleek edges.
However, porcelain slabs are heavy and brittle at the edges, so installation requires specialist tools and care. It is also frost- and UV-resistant, making it suitable for outdoor kitchens. In fact, its exposure to sun and heat does not fade or damage it.
Key Features:
Ultra-low porosity – 0% absorption. No sealing needed, totally stain-proof.
Heat and chemical resistant – resistant to acids (lemon, vinegar) and can take direct heat from pots.
UV- and frost-stable – ideal for indoor or alfresco use.
Extreme hardness – Mohs 6–7 (similar to granite); very scratch and chip resistant.
Lightweight slabs – 6–12mm profile (lighter than stone slabs), enabling slim, modern edges.
Huge design range – digital printing gives endless patterns (marble, wood, concrete, metal looks).

Natural Stone Benchtops | Timeless, Character-Rich Surfaces
Natural stone benchtops are quarried slabs of granite, marble, quartzite, travertine, etc. Each slab is a unique piece of Earth, so no two are alike. You get organic veins, colour swirls and textures.
Popular natural stone options:
Granite (hard, speckled, low-porosity)
Marble (soft, veined, high-porosity)
Quartzite (very hard and heat-resistant)
Travertine (warm and porous)
Natural stone exudes a luxurious, one-of-a-kind look that many Perth renovators love.
Porosity & Sealing: Natural stones vary in porosity: granite is generally quite dense (0.01–0.2% water absorption), while marble and travertine can be more porous (up to 0.5–3%). Porous stone must be sealed to prevent stains. Typically, stone benchtops are sealed at installation and then re-sealed every 6–12 months.
Over time, a well-sealed stone is hygienic, but spills should be wiped up quickly to avoid stains or etching.
Key Features:
Timeless beauty – natural marble/vein patterns and rich stone colours.
High durability – granite/quartzite resist scratches, heat, and wear very well. These stones will last decades with care.
Heat tolerance – most stones handle hot cookware (granite is effectively heatproof), though marble can crack if exposed to quick thermal shock (rare).
Cool touch – stone stays cool (pleasant for food prep).
Heavy, thick slabs – typically 20–30mm thick, very robust.
Unique each time – colour/pattern vary per slab

Silica-Free vs Porcelain vs Natural Stone: Cost Consideration
In Perth, you can generally expect installed costs roughly as follows:
Silica-free engineered stone: $400–$1,500/m²;
Porcelain: $800–$2,000/m²;
Natural stone: $700–$2,500/m² (depending on granite vs marble quality).
The final cost will vary with slab quality, colour, edge profile, sink cutouts or waterfall details, and installation complexity. It’s smart to get at least three local quotes before deciding.
What’s included: A quote usually covers the slab material, templating, cutting (including sink/bowl cutouts) and standard installation (sealant between slabs, fixing).
What’s not included: Undermount sinks, taps, plumbing, demolition, tiling and protective scaffolding are typically extra. Always clarify with your fabricator.
Kitchen Benchtop Maintenance Needs
Silica-Free Kitchen Benchtops – Very low upkeep. Simply wipe daily with a mild soap or household cleaner. No sealing or polishing is needed. These surfaces resist stains and are hygienic. Avoid abrasive cleaners. Minor chips or scratches are rare; if they occur, professional repair kits can restore the finish.
Porcelain: It’s almost maintenance-free. Its non-porous surface repels stains and doesn’t need any sealant. Clean with gentle detergent and a soft cloth; do not use harsh scrubbing pads. If a thin slab does chip at an edge, a specialist can often repair or replace the piece.
Natural Stone: More hands-on. All natural stone should be sealed initially and resealed periodically (every 6–12 months for marble, less frequently for granite). Wipe up spills quickly to avoid etching or stains (especially from wine, citrus, tomato sauce on marble). For scratches or dull spots, a professional polisher can re-hone the stone to look like new. With proper care, stone will last a lifetime.

So, Which One is Right for Your Kitchen?
To decide quickly: Ask yourself the following questions:
Health & uniformity: Do you want the healthiest option with consistent colours? → Choose silica-free engineered stone. It eliminates silica dust concerns and gives that perfect granite/marble look without variation.
Outdoor/low-maintenance: Do you want nearly zero upkeep and outdoor use? → Choose porcelain. It handles sun and heat effortlessly, never needs sealing, and cleans up in seconds.
Unique luxury: Do you crave a one-of-a-kind natural surface and don’t mind sealing? → Choose natural stone. Granite or marble will give character and long-term value in a high-end Perth renovation.
Exception notes: Consider your budget, bench size and sink type. For example, a long waterfall island may favour porcelain or engineered (to avoid multiple slabs) and undermount sinks usually cost extra in fabrication. Always review fabricator tech sheets and compare local quotes.

FAQs
Q1: Do porcelain benchtops have silica?
Porcelain is made from natural clays and minerals (which include silica) fired into ceramic. It contains no added quartz resin, so it doesn’t produce toxic silica dust. In fact, pure porcelain slabs are excluded from Australia’s engineered stone ban. They won’t harm your health or fade in the sun.
Q2: What’s the difference between porcelain and natural stone benchtops?
Porcelain is an engineered ceramic: non-porous, nearly maintenance-free, and UV-stable, available in extremely consistent patterns. Natural stone (granite, marble etc.) is quarried material: porous (needs sealing), each slab unique, and can react to acids (marble etches). Porcelain can be made thinner and used outdoors easily, whereas stone is thicker and more traditional in appearance.
Q3: Are silica-free benchtops safe for my family?
Yes. Silica-free engineered stone has no crystalline silica in its composition, so cutting or installing it doesn’t release dangerous dust. The finished surface is inert and non-toxic. It’s a very safe, hygienic kitchen surface; strong and easy to clean.
Q4: Do silica-free benchtops cost more?
They can be slightly more expensive than standard quartz. Since they use special non-silica formulas, they’re priced at the premium end of the engineered stone range. However, prices have been coming down as they become more common.
Q5: How long do porcelain benchtops last?
With normal use, for decades. Porcelain is extremely hard and durable. Industry experts say a well-installed porcelain benchtop can last a lifetime without losing its integrity. Because it doesn’t scratch or stain, it retains its appearance even after many years.
Q6: Are porcelain benchtops heat resistant?
Absolutely. Porcelain slabs are fired at over 1200°C, so they withstand high heat. You can place hot pots or trays on them without damage. But always exercise caution and never assume any countertop is completely indestructible.
Q7: Does natural stone need sealing?
Generally, yes. Most granite and all marble/travertine benchtops benefit from a protective sealer coat. Granite may go longer between seals, but marble and travertine usually need it every 6–12 months to protect against stains and spills. Without a seal, oils and liquids could penetrate and leave marks.
