Stone Benchtop Cost in Australia: The 2026 Price Guide

In 2026, most Australian kitchens spend between $400 and $1,000 per square metre for a stone benchtop, installed — with a typical mid-sized kitchen (around 6–8 m² of benchtop) landing between $3,000 and $7,500 all-in. Where you sit in that range comes down to five things: the material tier you choose, how many slabs and joins your kitchen needs, the edge profile, the cutouts, and who fabricates it. This guide breaks down each one, so the quotes you receive make sense — and so you can tell a fair price from a padded one.

What benchtop materials cost in Australia (2026, installed)

Material	Typical installed cost / m²	Worth knowing
Laminate	$150 – $350	Cheapest up front; joins and edges show, and moisture is its enemy
Timber (hardwood)	$350 – $700	Needs regular oiling/sealing; scratches and stains are part of the deal
Mineral surface (silica-free stone)	$450 – $1,000	The stone look and hardness without sealing — and the category Australian regulation now favours
Porcelain slab	$700 – $1,200	Very hard-wearing; thin profiles; chips are difficult to repair invisibly
Natural granite	$700 – $1,400	Genuinely tough; needs periodic sealing; colour range is what the quarry gives you
Natural marble	$900 – $2,500+	The original — and the most demanding: soft, porous, stains and etches

Ranges are typical 2026 quotes for supply, fabrication and installation in Australian metro areas. Your kitchen’s size, layout and site access move any material up or down its range.

Three worked examples (so the numbers feel real)

Per-square-metre figures only mean something multiplied by a real kitchen. Three common layouts, priced in a mid-tier silica-free mineral surface:

 

• • Galley kitchen, ~4 m², one straight run and no island. Simple fabrication, one slab, two cutouts. Expect roughly $2,000–$3,500 installed. This is the cheapest way into a stone benchtop.

• • L-shaped kitchen, ~7 m², with an undermount sink and cooktop. Two slabs, one join placed sensibly, standard edge. Roughly $3,500–$6,000 installed — the middle of the Australian market.

• • Island kitchen, ~10 m², with a waterfall end on the island. Three slabs, batch-matched, one mitred waterfall, three cutouts. Roughly $6,500–$11,000 installed — the waterfall alone is often $400–$1,200 of that.

If a quote lands wildly outside these shapes, ask why. There may be a good reason — difficult access, a premium tier, a complex layout — but it should be a reason someone can point to.

What’s actually inside an “installed” price

A stone benchtop quote is really three costs stacked together:

 

• • The slab — the material itself, chosen by colour and tier. This is usually only a third to half of the total.

• • Fabrication — cutting the slab to your kitchen’s templates, machining the edges, polishing, and cutting out the sink, cooktop and tap holes. Skilled work on hard material; it’s where cheap quotes usually cut corners.

• • Templating, delivery and installation — measuring your kitchen precisely, moving slabs that weigh hundreds of kilograms without damage, and fitting them dead level.

When two quotes differ sharply for the “same” stone, the difference is almost always in items 2 and 3 — or in what’s quietly been left out of one of them (ask specifically about cutouts, edge profile, and delivery).

And there’s one more cost that can dominate a quote when it applies — special fabrication processes. Thermoforming (heat-bending the surface into a curve), radius and curved work, and other non-standard shaping aren’t part of a flat benchtop. When your design calls for them, they add specialist labour and machine time, and can be one of the single largest variations on a quote — sometimes more than the slab itself. If your kitchen includes curved fronts, a bent splashback or radiused corners, ask for each to be itemised so you can see exactly what it’s adding.

The five things that move your price

 

• • Material tier. Within any surface range, more complex designs cost more to produce.   NEOTERRA® runs from the Standard range through Premium, Luxury, Luxury Ultra and Astra Nova — the same slab quality and the same 5-year limited warranty at every tier; what changes is the intricacy of the design.

• • Joins and slab count. Every join costs fabrication time, and a layout that needs three slabs costs more than one that needs two. Large-format slabs cover more kitchen with fewer joins — one of the quiet ways a better slab saves money at fabrication.

• • Edges. A standard pencil or arris edge is included in most quotes. Mitred waterfalls, shark-nose profiles and 40 mm+ built-up edges are priced accordingly (typically $200–$600 per lineal metre extra for a mitred waterfall end).

• • Cutouts. Undermount sink cutouts, flush-mounted cooktops and drainer grooves are each machined individually — typically $150–$400 per cutout depending on complexity.

• • Site and layout. Tight stair access, long carries, island sizes that force a specific slab orientation — anything that makes handling harder shows up in the quote.

Does thickness change the price?

Most Australian benchtops are 20 mm. The chunky 40 mm look you see in display kitchens is almost always created at the edge, not by a thicker slab — a built-up edge laminates an apron onto a 20 mm surface. So thickness is really an edge-profile decision, and the profile you choose is what moves the price: simple profiles like a pencil or arris edge are usually included, while more involved ones — a built-up edge, or a decorative ogee — cost more to machine. Ask for the edge profile to be quoted as its own line.

Replacing an existing benchtop vs. starting fresh

Swapping a benchtop on existing cabinetry is the most common renovation job in this category, and it changes the maths in two ways. It adds a small cost: removal and disposal of the old top (typically $300–$800 depending on material and access). And it adds a checkpoint: your cabinets must be sound and level, because stone is far less forgiving of movement than the laminate it usually replaces — a good fabricator checks this at templating, not on installation day. Budget the removal, confirm the cabinetry, and a replacement otherwise prices the same as new work.

The process — and where the time goes

From decision to finished kitchen is typically two to four weeks: colour selection, then templating once cabinetry is in, then fabrication (the bulk of the time — usually one to two weeks), then installation, which is normally a single day. Two things protect both your timeline and your budget: decide on the actual slab, not a sample chip — colour changes after templating are the expensive mistake in this industry — and confirm stock before fabrication is booked. Because we hold over 25,000 square metres in Sydney stock with deliveries on our own fleet, “waiting on the slab” is rarely the thing that slows a NEOTERRA® job down.

Why you won’t see prices on slab suppliers’ websites

Stone benchtops aren’t bought like appliances. The slab is one input into a fabricated, installed result — so the meaningful number is always your fabricator’s quote for the whole job, not a slab price in isolation. That’s why suppliers like us work through fabricator networks: you choose the colour at full scale, your fabricator quotes the finished benchtop, and stock is confirmed before anything is cut. It also means the way to an accurate price is fast: visit the Regents Park showroom or request a sample, pick your colour, and we’ll connect the dots with your fabricator from there.

How to keep the cost sensible (without regretting it)

 

• • Decide on the full slab, not a sample chip. Colour changes after fabrication are the most expensive mistake in this category. Seeing the actual slab first costs nothing.

• • Design to the slab format. Ask your fabricator to lay out your kitchen against the slab dimensions early — fewer joins and less waste both cut the price.

• • Spend on the island, save on the run. Many kitchens put a Luxury-tier design on the island and a quieter Standard-tier colour on the perimeter — same warranty, same performance, meaningfully lower total.

Frequently asked questions

How much does a stone benchtop cost per square metre in Australia?

Typically $400–$1,000 per square metre installed in 2026, depending on material tier, edges, cutouts and layout. Laminate sits well below that; natural marble sits well above it.

How much should I budget for an average kitchen?

A mid-sized Australian kitchen carries roughly 6–8 m² of benchtop, so $3,000–$7,500 installed covers most stone benchtop projects — with simple layouts in entry-tier colours coming in under that.

How much does it cost to replace an existing benchtop?

The same as new work, plus removal and disposal of the old top — typically $300–$800. Your cabinetry needs to be sound and level; a good fabricator confirms that at templating.

How long does a stone benchtop take from order to installation?

Usually two to four weeks: selection, templating, one to two weeks of fabrication, and a single installation day. Confirming slab stock up front is the best protection against delays.

Why don’t stone suppliers publish prices online?

Because the slab is only part of the cost. The finished price depends on your kitchen’s templates, joins, edges and cutouts — fabrication decisions made after measuring your kitchen. The accurate number is your fabricator’s quote; the fast path to it is choosing your colour at a showroom first.

Is a silica-free benchtop more expensive?

No. Silica-free surfaces are the standard stone benchtop category, priced within the normal stone benchtop range — typically $450–$1,000 per square metre installed.

What adds the most to a benchtop quote?

Waterfall ends and mitred edges, extra slab count and joins, and multiple cutouts. A design tweaked to suit the slab format almost always quotes lower than one designed without it.

How do I get an accurate price?

Choose your colour at full scale — book a showroom visit— then have your kitchen templated by your fabricator. With the colour and layout fixed, the quote you get is the price you pay.
