Kitchen benchtop replacement cost is the first question every homeowner asks us, and we get asked it almost every week.
After nearly 15 years cutting, templating, and installing stone across Melbourne homes, the answer we give is always the same. It depends on three things: the material you choose, the size of your kitchen, and a handful of installation factors that most suppliers gloss over in their quotes.
What has changed in 2026 is the market itself. The July 2024 ban on traditional engineered stone containing crystalline silica permanently removed the most popular benchtop material of the last two decades from the Australian market. If you’re planning a kitchen benchtop replacement this year, you need to understand what that means for your options and your budget before you call a single supplier.
This blog will examine all the different factors that influence you to replace kitchen benchtops; it will give you an overview of popular materials available and their price range, and help you decide whether to do it yourself or call in a professional.
2026 Melbourne Benchtop Replacement Costs at a Glance
Most Melbourne kitchens use between 4 and 6 square metres of benchtop. That means the per-square-metre figure you see in most guides translates to a total project cost that surprises a lot of homeowners. Here is what you can realistically expect to pay for a full supply-and-install replacement in 2026, based on what we see quoted across Melbourne:
| Material | Cost per m² | Typical Melbourne kitchen | Maintenance |
|---|---|---|---|
| Laminate | $120 – $350 | $1,200 – $2,500 | Wipe clean, no sealing |
| Porcelain slab | $350 – $600 | $2,500 – $5,000 | Wipe clean, no sealing |
| Granite | $400 – $1,000 | $2,500 – $7,000 | Reseal every 12 to 18 months |
| Low-silica engineered stone | $450 – $900 | $3,000 – $6,500 | Wipe clean, no sealing |
| Timber | $300 – $800 | $2,000 – $6,000 | Oil or seal regularly |
| Marble | $600 – $1,200 | $3,500 – $9,000 | Reseal every 12 months |
These figures give you a baseline for supply and installation. Your final price depends on slab grade, thickness, edge profiles, cut-outs, and site access.
How the Engineered Stone Ban Affects Your Kitchen Benchtop Replacement Budget
Australia banned engineered stone containing 1% or more crystalline silica on 1 July 2024. The law followed a tragic surge of silicosis cases among Australian stonemasons, hitting families right here in our trade community.
You can’t legally buy traditional slabs from Caesarstone, Quantum Quartz, Smartstone, or Essastone for new kitchen fitouts anymore.
This change completely reset pricing for Melbourne kitchen renovations. Demand surged for natural stone like granite, marble, and quartzite, which drove market prices upward.
Porcelain slabs became the go-to alternative for mid-range budgets. The ban only covers engineered stone as defined in the regulations, so porcelain and sintered stone products that contain no resin sit outside it entirely. Factories are rolling out new zero-silica or low-silica engineered alternatives in 2026, though production quality varies while the technology matures.
If any supplier offers you engineered stone in 2026, it must be a new-generation product containing less than 1% crystalline silica. Ask for the manufacturer’s declaration or test certificate proving the silica content before you sign anything. Traditional engineered stone cannot be legally supplied or installed in new kitchens, no matter what paperwork comes with it.
Kitchen Benchtop Replacement Cost by Material in Melbourne
Granite Benchtop Replacement Cost
Granite is the workhorse of quality Melbourne kitchens and has been for generations. It is hard, heat-resistant, and every slab is unique. Since the engineered stone ban, we have seen renewed interest in granite across Melbourne, particularly Cosmic Black with its distinctive gold veining and standard grey speckled options that suit modern cabinetry. Supply and install cost of granite benchtops in Melbourne run from $400 to $1,000 per square metre, with a typical kitchen falling between $2,500 and $7,000. Granite needs sealing on installation and resealing every 12 to 18 months, which takes about 20 minutes and costs very little.
Marble Benchtop Replacement Cost
Homeowners walk into our Melbourne showroom and fall straight for marble. We get it.
Calacatta, Carrara, and Statuario slabs carry an elegance you cannot fake in a factory. A full marble kitchen replacement runs between $3,500 and $9,000. Your final price depends entirely on the specific slab and the layout of your space.
But you need to know marble is a living surface. Lemon juice and vinegar will etch it. You must seal it every year.
We tell our clients to expect a benchtop that develops character over time. If you demand a flawless surface that never changes over decades of use, look at porcelain instead.
Porcelain Slab Benchtop Replacement Cost
Porcelain took over the Melbourne market after the engineered stone ban. We install a massive amount of it.
The surface is completely non-porous. It handles hot pans and resists heavy stains without ever needing a drop of sealer. Modern porcelain designs also do a brilliant job mimicking natural marble and granite.
Basic supply and installation for a standard kitchen sits between $2,500 and $5,000. If your layout requires laser templating, CNC waterjet cutting, and a complex fit, budget between $5,000 and $6,500.
We confidently recommend porcelain for busy family households. It easily handles the daily chaos.
Low-Silica Engineered Stone Benchtop Replacement Cost
New-generation low-silica products are now available in Melbourne and are fully legal. They deliver the consistent colour and non-porous surface that engineered stone became popular for. Costs run from $450 to $900 per square metre installed. Our advice in 2026: ask for documented warranty coverage and a written compliance certificate before committing. The products are improving, but production quality still varies between manufacturers.
Stop guessing at $400 a square metre.
Five Things that Move the Final Kitchen Benchtop Replacement Price Up or Down
The per-square-metre figure is only the starting point. In our experience, these five factors move the final kitchen benchtop replacement cost the most:
- Kitchen size and slab area: Most Melbourne kitchens use 4 to 6 square metres. An island, waterfall edge, or butler’s pantry adds slab area and cost accordingly.
- Slab grade and rarity: Standard granite and porcelain deliver the best value per dollar. Premium slabs, rare natural stones, and book-matched marble pairs cost significantly more. Always view slabs in person before committing.
- Thickness and edge profile: A 20mm top with a simple pencil or bullnose edge keeps fabrication cost down. A 40mm mitred edge adds to both material and labour cost. Waterfall panels add $800 to $2,000 per end.
- Cut-outs and complexity: Every sink, cooktop, and tap hole cut-out adds fabrication time. Undermount sinks cost more than drop-in sinks because they require precise cuts and adhesive installation.
- Removal and plumbing: Every replacement needs the existing benchtop removed and the sink disconnected and reconnected. Budget $150 to $350 for a licensed plumber regardless of which material you choose.
Kitchen Benchtop Replacement or Overlay: Which Do You Need?
If your existing benchtop’s substrate is sound but the surface looks tired, an overlay, a new stone surface fitted directly over the old one, skips demolition and often finishes in a day. It suits kitchens where the cabinets and plumbing are in decent shape, and you just want the surface refreshed.
If the substrate’s damaged, you’re changing the depth, or fitting an undermount sink, you need a full replacement. It takes longer and involves disconnecting plumbing, but it’s the right call when the old top can’t be trusted to carry a new surface. We check the substrate on-site before quoting either option. Guessing from photos gets this wrong more often than you’d think.
How to get the Best Value on Your Kitchen Benchtop Replacement
- Get three quotes, and compare them on the same basis: templating, fabrication, delivery, installation.
- Have your floor plan ready with sink and cooktop marked. A supplier who can’t quote from it isn’t set up to give you an accurate number.
- Lock in your edge profile early. Waterfalls and mitred edges cost more than usual. It’s important to look into this before you accept a quote.
- Order the splashback with the benchtop if you want them matching. Stone varies between batches, and a match ordered later rarely lines up.
- Set aside 10 to 20% above the quote. Substrate surprises and plumbing complications happen.

Kitchen Benchtop Replacement Cost: FAQs
1. How much does kitchen benchtop replacement cost in Melbourne in 2026?
2. Is engineered stone still available in Melbourne in 2026?
3. What is the most affordable stone benchtop in Melbourne?
Entry-level granite and standard porcelain slab are the most affordable stone benchtop options, both starting from around $400 per square metre supplied and installed. Both materials deliver excellent durability and performance at the more accessible end of the stone price range.
4. Can I replace just the benchtop without replacing the cabinets?
Yes, and it is one of the most popular upgrades we do. Your cabinets only need to be in sound structural condition. Replacing the benchtop alone transforms a kitchen completely and costs a fraction of a full renovation. We assess the substrate on every job before templating.
5. How long does the process take?e cabinets?
Templating takes 30 to 60 minutes on site. Stone fabrication takes two to four weeks. Installation of a standard Melbourne kitchen takes two to four hours. Allow three to five weeks from ordering to completed installation. If you are coordinating other trades, order your benchtop first.
6. Do I need to seal my new benchtop?
Porcelain and low-silica engineered stone require no sealing. Granite needs sealing on installation and resealing every 12 to 18 months. Marble needs annual sealing and a pH-neutral cleaning routine to protect against etching. Stonaa seals every natural stone installation as standard practice.
7. How do I get an accurate quote?
The most accurate kitchen benchtop replacement cost comes from an on-site templating appointment. We measure your exact kitchen dimensions, assess the substrate, and provide a detailed itemised quote covering templating, fabrication, delivery, and installation.
