Engineered Stone Ban Australia: What Cabinet Makers Must Clarify in Every Kitchen Quote
The ban changed more than the material list. It changed what a kitchen quote has to say about who supplies, templates, fabricates and installs the benchtop - and what happens when there is already engineered stone on site.
The short answer
The engineered stone ban is a scope problem, not just a materials problem. Manufacture, supply, processing and installation of engineered stone benchtops, panels and slabs have been prohibited nationally since 1 July 2024, and importing them since 1 January 2025. Name the actual product rather than “stone”, name who supplies, templates, fabricates and installs it, and treat existing engineered stone as a separate specialist workflow - including the re-installation trap, where lifting a top to fix the cabinetry underneath is still regulated work.
A cabinet maker wins a kitchen renovation. The quote contains one line about the benchtop: “Stone benchtop by others.” Everyone nods. Nobody writes down which stone, which supplier, who templates it, who cuts the sink hole, who carries it in, or what happens to the engineered stone top already sitting on the old cabinets.
Six weeks later the cabinetry is installed, the fabricator cannot template because an appliance has not been confirmed, the client believes the old benchtop is being “put back on afterwards”, and someone on site suggests the cabinet maker just trim the existing top by 20 mm to suit the new layout.
That last request is not a small favour. It is regulated work. And the earlier problems are not bad luck either - they are what happens when a benchtop is described as a category instead of a scope.
This is not a legal explainer. It is a practical guide for Australian cabinet makers, estimators and installation managers on making the benchtop boundary clear before a job reaches production.
What the engineered stone ban actually covers
On 1 July 2024 the Commonwealth and all states and territories implemented amendments to the model WHS Regulations making it an offence for a person conducting a business or undertaking (a PCBU) to carry out, or to direct or allow a worker to carry out, work involving the manufacture, supply, processing or installation of engineered stone benchtops, panels or slabs. On 1 January 2025 those products also became prohibited imports under the Customs (Prohibited Imports) Regulations 1956, enforced at the border by the Australian Border Force.
Note the four verbs. A cabinet-making business does not need to own a stone saw to be captured. Supply and installation are both in the list, which is exactly where a head-contracting cabinet maker or joinery business sits when it sells a complete kitchen.
The definition is about composition, not appearance
For the purposes of the model WHS Regulations, engineered stone is an artificial product that contains at least 1% crystalline silica as a weight/weight concentration, is created by combining natural stone materials with other chemical constituents such as water, resins or pigments, and becomes hardened.
Safe Work Australia lists the products that are not engineered stone for this purpose: concrete and cement products; bricks, pavers and similar blocks; ceramic wall and floor tiles; sintered stone, provided it does not contain resin; porcelain products, provided they do not contain resin; roof tiles; grout, mortar and render; and plasterboard.
The practical takeaway: “stone-look” does not mean “engineered stone”, and a slab that looks identical to a banned product may sit entirely outside the definition. It works the other way too. Material identification should come from the supplier and the product documentation, never from the way a sample looks on the showroom bench.
One more thing worth confirming rather than assuming: Safe Work Australia notes that each jurisdiction had to amend its own WHS laws to give the ban effect, and that implementation may vary slightly from jurisdiction to jurisdiction. If a business operates across state borders, the relevant regulator's guidance is the source of truth, not a summary like this one.
The material category mistake that causes quote problems
Most benchtop disputes do not start with a compliance question. They start with a description that was never specific enough to argue about. Six materials commonly appear in Australian kitchen work, and they behave very differently commercially.
| Material | Where it sits after the ban |
|---|---|
| Engineered stone | Prohibited as benchtops, panels and slabs. Manufacture, supply, processing and installation are all captured. |
| Natural stone | Outside the engineered stone definition. Still a crystalline silica substance, so processing controls and WHS duties apply. |
| Porcelain | Outside the definition provided the product does not contain resin. Confirm against product documentation. |
| Sintered stone | Outside the definition provided the product does not contain resin. Confirm against product documentation. |
| Laminate | Outside the definition. Usually processed in the joinery workshop rather than by a stone fabricator, which moves the responsibility boundary. |
| Timber and other composites | Outside the definition. Check the specific product rather than assuming the category. |
A quote line that says only “stone benchtop” is commercially weak for a simple reason: it identifies no product, no supplier and no processing responsibility. If the client later selects a different material, nobody can point to what was priced. If the fabricator cannot template on time, nobody can point to whose obligation it was.
Compare three ways of writing the same line item:
- Vague. “Stone benchtop.”
- Specific. “Porcelain slab benchtop supplied and installed by nominated stone fabricator.”
- Specific, with the boundary. “Cabinetry only. Benchtop excluded. Final benchtop template subject to completed cabinet installation and site readiness.”
None of these take longer to write. The difference is that two of them survive a dispute. It is the same discipline that makes structured pricing work: how parametric pricing helps cabinet makers quote consistently depends on knowing exactly what is in the quote and what is not.
Who is responsible for what?
A typical kitchen job involves a cabinet maker, a builder, a designer, a stone fabricator, an installer and the client. The benchtop is the one component almost every one of them touches, which is why it generates so many variations.
Use this matrix as a starting point and adapt it to how your business actually contracts. The value is not the table. The value is that every row has a name against it before the job is released to production.
| Item | Cabinet maker | Stone fabricator | Builder or client |
|---|---|---|---|
| Material selection and documentation | Record the selection on the job | Confirm product and supply documentation | Approve the selection in writing |
| Cabinet dimensions | Confirm and issue | Use for template | Approve layout and appliance positions |
| Site measure and template | Deliver installed, levelled cabinetry | Complete the template | Ensure site access, power and clear benches |
| Sink and appliance cut-outs | Coordinate and pass on specifications | Fabricate to the confirmed specification | Confirm final appliance and sink models |
| Transport and handling | State inclusion or exclusion in the quote | State inclusion or exclusion in the quote | Provide access and a clear path |
| Benchtop installation | State clearly whether included | State clearly whether included | Coordinate the site sequence |
| Splashbacks and return panels | Confirm the interface with cabinetry | Fabricate and install as contracted | Approve the finish and joins |
| Legacy engineered stone handling | Exclude unless separately contracted | Specialist controlled process | Arrange a qualified contractor |
Two rows deserve particular attention. The template row is where most programme disputes begin, because templating depends on work the cabinet maker controls and site conditions the cabinet maker does not. The legacy engineered stone row is where the compliance risk sits, and it is the one most likely to be settled verbally on site.
Legacy engineered stone is a different job
Engineered stone already installed in a home or workplace is not required to be removed because of the ban. Safe Work Australia describes it as legacy engineered stone: any engineered stone benchtop, panel or slab already installed, and for disposal purposes, engineered stone whether installed or not.
What is regulated is the work performed on it. Processing of legacy engineered stone remains permitted for a limited set of purposes: removing, repairing, making minor modifications to, or disposing of installed engineered stone, and disposal of engineered stone whether installed or not.
That permission comes with conditions. A PCBU proposing to carry out that work must notify the WHS regulator before doing so and must ensure any processing is controlled. Safe Work Australia notes one jurisdictional difference worth knowing: in Victoria, employers are not required to notify the regulator, although controlled processing is still required.
The re-installation trap most cabinet makers do not expect
Here is the scenario that catches joinery businesses out. A client wants the cabinets under an existing engineered stone benchtop repaired, refaced or replaced. The top is in good condition. The plan is to lift it off carefully, do the cabinetry work, and put the same top back in the same place without cutting it.
Safe Work Australia is explicit that under the model WHS Regulations the prohibition applies to installation, and that this includes re-installation even if no processing is required. Safe Work Australia Members have agreed this is an unintended consequence of the amendments and are considering how best to address it. As an interim solution, exemptions permitting re-installation in specific circumstances have been granted in all jurisdictions.
Those exemptions are narrow and conditional. SafeWork NSW Exemption 24-035, which commenced on 9 May 2025, illustrates their shape. It applies only to re-installing a benchtop, panel or slab that was temporarily removed to enable work to the underlying cabinetry or supporting structure, or to give access to repair or modify an underlying component. Its conditions include:
- the benchtop must be re-installed in the same location at the same address from which it was removed
- permitted processing is limited to minor modification to enable re-installation, or repair of damage caused during removal, re-installation or that minor modification
- any processing must be controlled
- the PCBU must notify SafeWork NSW of processing undertaken
It also does not apply to installing a replacement engineered stone benchtop if the original cannot be re-installed. Other jurisdictions have granted their own exemptions on their own terms and timing, so the NSW conditions are an example rather than a national rule.
A practical rule for the workshop and the site: if an existing engineered stone surface needs to be cut, drilled, ground, polished, removed, re-installed or disposed of, stop and confirm the lawful pathway before proceeding. Do not treat it as a casual variation or a “small adjustment” while the installers are already on site.
Situations that should trigger that pause include:
- Removing or replacing cabinets under an existing top
- Re-installing a top after access or repair work
- Enlarging or relocating a sink or cooktop cut-out
- Trimming a top to suit a changed cabinet layout
- Cutting an existing splashback or return panel
- Drilling for a new tap, soap dispenser or filter
- Disposing of a removed benchtop or its offcuts
The commercial consequence matters as much as the compliance one. If a renovation quote does not separate legacy stone handling from new cabinetry work, the cabinet maker has effectively priced a scope it may not be able to lawfully perform, and has given the client an expectation that is expensive to walk back on site.
Quote wording that prevents variations
Clear wording is not about being difficult. It is about making sure the person reading the quote in three months can tell what was priced. The clauses below are examples to adapt, not legal drafting.
| What it protects | Example wording |
|---|---|
| Name the product, not the category | Benchtop: [product name and colour], [material type], supplied and installed by [named fabricator]. Selection confirmed in writing before production release. |
| Make the template dependency explicit | Final template to be completed only after cabinetry is installed, levelled and the site is ready. Dimensions shown in this quote are indicative until template is complete. |
| Tie cut-outs to confirmed specifications | Sink, tap and appliance cut-outs are fabricated to the specifications supplied by the client. Changes after template are treated as a variation. |
| Exclude processing of existing stone | This quote excludes the cutting, drilling, grinding, polishing, modification, removal, re-installation or disposal of any existing engineered stone benchtop, panel, slab or splashback. |
| Price the selection, not the category | Pricing is based on the material selection recorded above. A change of material category may change the price, the lead time and the installation responsibility. |
| Make delay responsibility visible | Delays caused by late material selection, late appliance confirmation or site access being unavailable at the agreed template date are treated as a variation. |
| Carve out the legacy stone pathway | Where work involves existing engineered stone, that scope is excluded unless separately contracted and carried out under the lawful pathway confirmed with the relevant WHS regulator. |
Two habits make these clauses work. First, the material selection has to be recorded somewhere the production team can see it, not just agreed in a showroom conversation. Second, the exclusions have to survive into the job. An exclusion that exists only in the original PDF is not much use to an installer standing in a kitchen on a Friday afternoon.
Turn the benchtop boundary into a workflow checkpoint
The engineered stone ban is usually discussed as a materials question. For a cabinet-making business it is really a handover question, and handovers are solved with checkpoints rather than good intentions.
A simple, effective control is to refuse to release a kitchen job to production or installation while the benchtop responsibility is unresolved. Before the job moves:
- Benchtop material and product confirmed in writing
- Supplier product documentation stored against the job
- Fabricator and installer named on the job record
- Sink, tap and appliance specifications confirmed
- Responsibility boundary documented in the accepted quote
- Site measure or template status recorded
- Installation sequence agreed with the builder or client
- Legacy engineered stone risk flagged and pathway confirmed
Each of those items is information that already exists somewhere in most businesses. The problem is where it lives: the material selection is in an email, the fabricator's name is in a text message, the appliance specification is in a photo on someone else's phone, and the exclusion is in a PDF nobody opened after acceptance.
When the same job runs alongside eight others, that scattering is what turns a documented boundary into a verbal one. The coordination discipline is the same one described in manage multiple cabinet projects without losing track of scope: decisions have to stay attached to the job, not to the person who happened to make them.
How to explain this to clients without sounding difficult
Clients do not want a regulatory briefing. They want to know their kitchen will be finished properly and that nobody is setting them up for a surprise invoice. A short, confident explanation usually does more than a long one.
“The benchtop selection and installation are documented separately because different materials have different compliance and fabrication requirements. We want to make sure the right supplier is responsible for the right stage, and that your cabinets are ready for templating so nothing gets measured twice.”
Where there is existing engineered stone on site, the same approach applies:
“Your existing benchtop is engineered stone, which is now regulated work. It does not have to be removed, but anything that involves cutting it, taking it off or putting it back has to be handled by a qualified specialist under the right approvals. We will quote the cabinetry, and we will tell you exactly what sits outside our scope so you are not caught out mid-job.”
This protects the relationship and the boundary at the same time. The client hears competence, not obstruction.
Clear benchtop responsibility protects safety, margin and dates
The engineered stone ban changed more than which slabs can be bought. It changed what a clear kitchen quote and handover has to contain. For cabinet makers, the practical response is short:
- Identify the material precisely, from supplier documentation
- Stop treating “stone” as a sufficient description
- Name who supplies, templates, fabricates, transports and installs
- Treat legacy engineered stone as a separate specialist workflow
- Write the exclusions into the quote and the pre-production checks
- Keep all of it attached to the job from quote through to installation
None of that requires a compliance department. It requires the benchtop to be treated as a scope item with an owner, rather than a line everyone assumes someone else is handling.
Most benchtop disputes are not caused by a lack of knowledge. They are caused by the decision being made correctly and then losing its way between the quote, the email thread and the installer's ute. CabiPro keeps quote inclusions, material selections, supplier details, job notes and installation responsibilities connected in one job record, so the scope decision is still there when someone needs it on site.
Frequently asked questions
What does the engineered stone ban mean for cabinet makers?
Since 1 July 2024 it has been an offence for a person conducting a business or undertaking to carry out, or to direct or allow a worker to carry out, work involving the manufacture, supply, processing or installation of engineered stone benchtops, panels or slabs. Supply and installation are both captured, so a cabinet maker selling a complete kitchen is inside the scope even without owning a stone saw. The practical effect is that the benchtop line can no longer be described loosely: the quote needs to name the product, the supplier, and who is responsible for templating, fabrication and installation.
Can cabinet makers still install porcelain or sintered stone benchtops?
Safe Work Australia states that engineered stone does not include sintered stone or porcelain products, provided they do not contain resin. Natural stone, laminate and timber also sit outside the definition. Material identification should come from supplier product documentation rather than an assumption based on appearance, and the broader work health and safety duties for crystalline silica still apply to any product that is cut, ground or polished.
Can a cabinet maker remove and re-install an existing engineered stone benchtop?
Not automatically. The prohibition applies to installation, and Safe Work Australia confirms this includes re-installation even where no processing is required. Safe Work Australia Members have agreed this is an unintended consequence, and as an interim solution exemptions permitting re-installation in specific circumstances have been granted in all jurisdictions. SafeWork NSW Exemption 24-035 is an example: it covers a benchtop temporarily removed to enable work to the underlying cabinetry, subject to conditions including re-installing it in the same location at the same address. Confirm the pathway with your state or territory WHS regulator before quoting the work.
Do I need to notify the WHS regulator before working with legacy engineered stone?
Safe Work Australia states that a person conducting a business or undertaking proposing to remove, repair, make minor modifications to or dispose of legacy engineered stone must notify the WHS regulator before doing so, and must ensure any processing is controlled. In Victoria employers are not required to notify the regulator, although controlled processing is still required. Check the notification process that applies in your own jurisdiction.
Does existing engineered stone have to be removed from a kitchen?
No. Engineered stone that is already installed is not required to be removed because of the ban. What is regulated is the work performed on it, including processing such as cutting, grinding, drilling or polishing, as well as removal, repair, minor modification and disposal. A renovation that disturbs an existing engineered stone benchtop should be planned as a separate specialist scope rather than treated as a small on-site adjustment.
What should a kitchen quote say about the benchtop?
At a minimum it should name the material and product, name the party responsible for supply, templating, fabrication, transport and installation, state that templating happens only after cabinetry is installed and the site is ready, list appliance and sink cut-outs as subject to confirmed specifications, and state clearly whether any work involving existing engineered stone is included or excluded. Wording should be reviewed against the business's own contract and legal requirements.
