We get the same call almost every week now. A homeowner in Woollahra or Mosman or Neutral Bay who had their heart set on a Caesarstone benchtop, who had picked the colour, who was ready to go, and who has just been told by their builder that it is no longer available.
The engineered stone ban caught a lot of people off guard. But here is what we tell every single one of those homeowners: this is not bad news. It is the best thing that could have happened to your renovation.
Because what replaces engineered stone is better in every way that matters. We have been working with sintered stone for years, and we have watched it quietly become the preferred surface of Sydney's best architects and interior designers long before the ban made the switch mandatory. Now it is everyone's turn to discover why.
This is the honest, complete guide to what the ban means, what your options are, and why sintered stone is not a compromise, it is an upgrade.
What Actually Happened: The Engineered Stone Ban Explained
On July 1, 2024, Australia became the first country in the world to ban the manufacture, supply, and installation of engineered stone products containing more than one percent crystalline silica. That includes Caesarstone, Silestone, Quantum Quartz, Smartstone, and every other engineered quartz product that has dominated Sydney kitchen renovations for the past twenty years.
The reason is not complicated. Engineered stone contains between 90 and 95 percent crystalline silica by weight. When it is cut and fabricated, it releases fine silica dust. Workers who breathe that dust develop silicosis, a progressive and irreversible lung disease that scars the lungs permanently. Australia was experiencing an epidemic of it among young stonemasons, workers in their twenties and thirties receiving terminal diagnoses.
Safe Work Australia concluded that there is no safe level of exposure. The ban was not cautious. It was necessary.
If you already have an engineered stone benchtop in your home, you are not affected. It is safe to live with and does not need to be replaced. But any new installation from July 2024 onwards must use a different material.
So What Are Your Options Now?
When homeowners first hear about the ban, the question we always get is: "What do I use instead?" The honest answer is that you have three real options, and one of them is significantly better than the others for most Sydney homes.
Natural stone (marble, granite, quartzite) is beautiful, genuinely unique, and has a warmth that no manufactured surface fully replicates. The trade-offs are real though. Natural marble etches under acid, absorbs moisture, requires regular sealing, and demands careful maintenance. For a busy family kitchen, it is a commitment many homeowners underestimate until they are living with it.
Porcelain is affordable and practical, but it has limitations. The surface depth is thin, it can look flat and manufactured at close range, and it chips more easily than harder surfaces. It works well in the right application but it is not a direct replacement for the premium feel of engineered stone.
Sintered stone is what we recommend for the overwhelming majority of our clients, and not because we sell it. Because it genuinely solves every problem that the engineered stone ban created, and then some.
What Is Sintered Stone and Why Is It Different?
Sintered stone is made by taking raw minerals, feldspar, silica, glass, and natural clays, and subjecting them to extreme heat and pressure. We are talking about temperatures above 1200 degrees and pressure that replicates geological forces. What comes out the other side is a fully mineralic material with no polymer resins, no plastic binders, and no organic additives of any kind.
That last part is what makes all the difference. The reason engineered stone became dangerous was the resin. The resin is also the reason it scorched under heat, yellowed outdoors, and degraded over time. Remove the resin and every one of those problems disappears.
Sintered stone is legal because the silica it contains is chemically bound into the mineral matrix. When you fabricate sintered stone, it does not release the fine airborne crystalline silica particles that caused silicosis. The material is fundamentally different at a molecular level, not just a marketing repositioning.
Brands you may have already heard of include Dekton, Neolith, Lapitec, and Laminam. These have been specified by leading Sydney architects and designers for years. The ban has simply brought them to the attention of homeowners who were previously defaulting to engineered quartz out of habit.
How Does Sintered Stone Actually Perform in a Real Sydney Home?
This is the question that matters. Not the technical specifications but the lived experience. What is it actually like to have a sintered stone benchtop in your kitchen every day?
We asked ourselves this same question when we first started working extensively with the material, and the answer from every client who has lived with it is consistent. It is the easiest surface they have ever owned.
Heat: You cook pasta, you drain it, you put the hot pot on the bench. With an engineered stone benchtop, you just created a permanent white heat mark. With sintered stone, nothing happens. The surface handles temperatures above 300 degrees without scorching, discolouring, or cracking. No trivets. No anxiety. Just cook.
Staining: Red wine on a Friday night. Coffee on a Sunday morning. Turmeric from a curry that got away from you. On sintered stone, every single one of these wipes away cleanly because the surface is genuinely impermeable. Nothing soaks in. Nothing stains permanently. A damp cloth is all you ever need.
Outdoors: This is the one that surprises Sydney homeowners most. Engineered stone cannot go outside. The polymer resins yellow and break down under UV exposure. Sintered stone was designed for outdoor use. We install it on outdoor kitchen benchtops, alfresco dining surfaces, and pool surrounds across the Eastern Suburbs regularly. It performs identically indoors and outdoors, which means you can run the same surface continuously from your indoor kitchen through to your alfresco area without a join, without a material change, and without worrying about the weather.
Maintenance: Zero sealing required. Ever. Clean with any household product. The surface you install today will look exactly the same in fifteen years as it does on the day we hand it over to you.
Does It Actually Look Good? The Honest Answer.
Five years ago, this was a fair concern. The earlier generation of sintered stone surfaces had a slightly flat, manufactured appearance that experienced designers could identify immediately.
That is no longer the case. The current generation of sintered stone surfaces, particularly at the premium end of collections like Dekton and Neolith, are genuinely difficult to distinguish from natural stone even at close range. We have had clients visit our Alexandria showroom convinced they were looking at real Calacatta marble until we told them otherwise.
The Calacatta look, the Statuario look, dramatic book-matched surfaces, concrete aesthetics, dark absolute surfaces, all of these are available in sintered stone today at a quality level that was simply not possible a few years ago. The manufacturing technology has caught up with the ambition.
And for those who want genuine natural stone, we supply and fabricate that too. But for clients who want the marble look without the maintenance reality of natural marble, sintered stone is the honest recommendation.
What Does Sintered Stone Cost in Sydney?
We get this question every day, and the honest answer is: it depends on the surface, the size of your project, and the complexity of the fabrication. But as a general guide for Sydney homeowners planning a kitchen renovation in 2025 and 2026:
Entry-level sintered stone slabs are positioned at a similar price point to premium engineered stone. Mid-range sintered stone, which is where most of our residential clients land, sits at a price comparable to what you would have paid for a good quality Caesarstone installation before the ban. Premium sintered stone, the large-format dramatic surfaces with complex veining patterns, commands a higher price that reflects the production complexity.
The more useful way to think about cost is over the life of the surface. Sintered stone requires no sealing, no specialist cleaning products, and no repairs from heat damage or acid etching. A sintered stone benchtop installed in your home today should cost you nothing in maintenance for the life of the property. When you calculate that against the ongoing costs of maintaining a natural stone surface or replacing a heat-damaged engineered stone benchtop, the value equation becomes very clear.
Why Seeing the Full Slab Matters More Than You Think
Here is something nobody tells you when you are choosing a benchtop surface. The sample is almost useless.
A 300 millimetre tile or offcut tells you the general colour and gives you a hint of the pattern. What it cannot tell you is how that pattern reads across a 3.2 metre benchtop. It cannot show you how the veining sweeps across the full width of your kitchen island. It cannot show you how the surface changes from the cool morning light of an east-facing kitchen to the warm afternoon light of a north-facing one.
At our Alexandria showroom, we display every slab at full size. 1600 by 3200 millimetres, standing vertically, in natural light. You stand in front of the actual slab you are considering for your home. You see it at scale. You see it in light. You make the decision with complete information.
We do this because we watched too many clients make the wrong choice from a sample and discover it only when the stone arrived on their benchtop. We decided that is not good enough. See the full slab. Make the right decision. Full size, full story.
The End-to-End Difference: Why One Team Changes Everything
Choosing the right stone is only one part of getting a result you will love. The fabrication and installation are equally important, and this is where a lot of Sydney renovation projects go sideways.
When your stone supplier, your fabricator, and your installer are three different businesses, nobody fully owns the outcome. Measurements get miscommunicated between companies. Damage happens during transit and nobody accepts responsibility. Scheduling between three separate businesses blows out timelines. And when something is not quite right, everyone points at someone else.
At Dulux Marble and Stone, the same team does everything. We help you choose the stone in our showroom. We cut and finish it in our own workshop. Our installation team fits it in your home. One conversation, one point of contact, one standard of care from beginning to end.
If anything is ever not right, one phone call resolves it. We are not going to tell you it is the fabricator's problem or the supplier's issue. It is our job, from the first slab you see to the last edge we finish.

Frequently Asked Questions About the Engineered Stone Ban
Is my existing Caesarstone or quartz benchtop safe?
Yes. The ban applies to new installations only. If you already have an engineered stone benchtop, it is safe to use and does not need to be replaced. The health risk was to the workers fabricating the material, not to homeowners living with the finished surface.
Can I still buy engineered stone benchtops anywhere in Australia?
No. From July 1, 2024, engineered stone products containing more than one percent crystalline silica cannot be legally manufactured, supplied, or installed anywhere in Australia. This applies nationally across all states and territories.
Is sintered stone safe to fabricate?
Yes. Sintered stone does not release respirable crystalline silica particles in the same way engineered stone does. It remains legal for manufacture, supply, and installation across Australia.
How long does it take to supply and install a sintered stone benchtop?
From consultation to installed benchtop, a typical residential project runs between two and four weeks depending on complexity and our current scheduling. We can give you an accurate timeline at your initial consultation.
Do I need to seal sintered stone?
No. Sintered stone requires no sealing at installation or at any point during its life. It is impermeable from the factory and stays that way.
Can sintered stone go outside?
Yes. Sintered stone is fully UV-stable and designed for outdoor use. It is one of the very few benchtop materials that can be used continuously from an indoor kitchen through to an outdoor alfresco surface.
