Kitchen benchtop cost by material after the engineered stone ban
What a kitchen reno costs in Australia with laminate, timber, solid surface, low-silica, granite or porcelain benchtops, and what the stone ban means.
In a mid-range Australian kitchen reno with about 4.5 m of base cabinetry, the benchtop is the second-biggest choice after the cabinets. With a laminate benchtop the whole kitchen, installed, typically costs about $18,000 including GST. With a low-silica engineered surface, our mid-range default, it is about $20,000; with porcelain or sintered stone, around $21,400. Appliances and flooring are not included in any of these figures.
Traditional engineered stone is no longer on the list. Since 1 July 2024, engineered stone containing 1% or more crystalline silica has been banned in Australia. Low-silica engineered surfaces and porcelain or sintered stone are still allowed.
The same kitchen, different benchtops
Each row is the same mid-range kitchen - soft-close cabinetry, sink, splashback, plumbing, electrical, painting and installation - with only the benchtop changed. Figures include 10% GST.
| Material | Typical | Usual range | Lifespan |
|---|---|---|---|
| Laminate worktop | $18,000 | $14,000 – $23,400 | – |
| Solid surface (acrylic) | $19,300 | $15,000 – $25,000 | – |
| Solid wood / butcher block | $20,000 | $15,600 – $26,000 | – |
| Low-silica engineered surface | $20,000 | $15,600 – $26,000 | – |
| Sintered stone / porcelain slab | $21,400 | $16,700 – $27,800 | – |
| Granite | $22,700 | $17,700 – $29,500 | – |

The engineered stone ban in practice
For years, engineered stone was the default benchtop in Australian kitchens. The ban was introduced because cutting and polishing it releases respirable crystalline silica dust, which has caused serious lung disease, including silicosis, in stonemasons.
What it means for you:
- You cannot have a new engineered stone benchtop with 1% or more crystalline silica fabricated and installed.
- Low-silica engineered surfaces are allowed. Ask the supplier to confirm the product's silica content in writing.
- Porcelain and sintered stone are allowed, and have become a common replacement.
- Natural stone such as granite is not covered by the ban, but cutting any stone produces dust, so fabrication still belongs in a workshop with proper dust controls.
If a quote still describes a benchtop simply as "engineered stone" or "quartz", ask exactly which product it is.
The benchtop options
Laminate
The cheapest option ($18,000). Modern laminates imitate stone and timber well and can be cut on site. Joints and edges are the weak points: water getting in makes the board swell.
Timber
Solid timber benchtops ($20,000), such as blackbutt, spotted gum or oak, are warm and repairable. They need oiling regularly, especially around the sink.
Solid surface
Acrylic solid surface ($19,300) joins invisibly and can have an integrated sink, so it is easy to keep clean. It scratches more easily than stone but can be polished back.
Low-silica engineered surface
The closest replacement for the old engineered stone look ($20,000): consistent colour and a non-porous surface. Products and names vary, so compare warranties and silica content, not just the brochure.
Granite
Granite ($22,700) is hard, heat-resistant, and every slab is different. It needs sealing from time to time. Common colours cost much less than rare ones.
Porcelain and sintered stone
Porcelain and sintered slabs ($21,400) are thin and highly resistant to heat, stains and UV, so they work outdoors too. They are harder to cut and can chip at the edges if knocked, so fabricator skill matters.
Templating and the hidden extras
Stone-type benchtops are templated after the cabinets go in, cut in a workshop and installed a week or two later. Ask for these to be listed:
- Sink and cooktop cut-outs, drainer grooves and edge profiles
- Waterfall ends and splashbacks in the same material
- Joins on L-shapes and long runs
- Carrying heavy slabs upstairs or through tight access
The cabinets matter more
Cabinetry is usually the biggest single cost. Keeping the low-silica benchtop and changing only the cabinets, the same kitchen costs about $15,300 with flat-pack cabinets, $20,000 with mid-range soft-close cabinetry and $27,300 with custom joinery.
We build these prices from the hours each trade needs at local labour rates, plus materials, and check them against market prices and real quotes.
Licensing and GST
Moving or adding plumbing and electrical points must be done by licensed tradespeople under state licensing. Quotes to households include 10% GST, and so do our figures.
