Porcelain benchtops cost about $400 to $1,050 per square metre supplied and installed in Australia. The slab alone is roughly $350 to $550 per square metre. A standard galley or L-shaped Melbourne kitchen commonly lands between $5,000 and $6,500 installed, with premium brands and complex fabrication pushing published figures to $700 to $2,000 per square metre.
Those ranges are wide for a reason, and the reason is not the stone. Here is what actually moves a porcelain quote, and how to tell a complete quote from a cheap-looking one.
- Supplied and installed: about $400 to $1,050 per square metre for standard work.
- Slab only: roughly $350 to $550 per square metre, with premium brands higher.
- A standard galley or L-shaped kitchen commonly runs $5,000 to $6,500 installed.
- Fabrication, not the slab, is the biggest swing. Porcelain is hard and brittle, so it cuts slowly.
- Thin 6mm slabs are cheaper to buy but usually need a substrate, so the installed price barely drops.

What does a porcelain benchtop cost per square metre?
Published Australian ranges cluster in two bands. Standard supplied-and-installed work sits around $400 to $1,050 per square metre, which is the figure most Australian suppliers and Home Beautiful quote. Premium and design-led work is published higher, with Better Homes and Gardens putting porcelain at $700 to $2,000 per square metre, in the same territory as natural stone.

Why is the range so wide?
Five things move a porcelain quote, and only one of them is the slab.
1. Fabrication difficulty. This is the biggest and least understood factor. Porcelain is extremely hard and comparatively brittle, so it needs diamond tooling, slower feed rates and careful handling. The same mitred edge that takes an hour in granite takes longer in porcelain, and a mishandled slab cracks. Cheap porcelain quotes usually mean someone has priced it like granite.
2. Total square metres. Benchtops are priced by area, and an island adds more than people expect once the overhang and return are counted.
3. Thickness. Porcelain comes in 6mm, 12mm and 20mm. Thin 6mm is cheaper per slab but usually needs a substrate behind it and more fabrication, so the installed price does not fall as much as the slab price suggests. See our thickness guide for how the same logic works in stone.
4. Edges and cut-outs. A simple pencil edge is the cheapest outcome. Mitred 40mm edges, waterfall ends and undermount sink cut-outs each add fabrication hours. A waterfall edge also adds slab area, because the vertical panels are extra square metres.
5. The install itself. Access, the number of joins, removal of the old benchtop, and reconnecting plumbing and the cooktop all sit in the install line. A first-floor kitchen with a tight stair costs more to install than a ground-floor one.
Is porcelain cheaper than granite or engineered stone?
Porcelain sits close to granite on purchase price and below it on running cost. Granite needs resealing roughly every 12 to 18 months; porcelain is non-porous and never needs sealing, so the ownership cost is lower over a decade.
Engineered stone is no longer a price comparison in Australia. The product was banned from 1 July 2024 under Safe Work Australia rules, so quartz-resin benchtops are not a costing option regardless of price. Porcelain and sintered stone sit outside that ban because they contain no resin, which is a large part of why porcelain demand rose so sharply. Our guide to the ban covers what is still legal.
What should a complete porcelain quote include?
Compare inclusions, not headline numbers. A complete quote covers on-site templating after the cabinets are installed, the slab, fabrication of edges and cut-outs, delivery, installation, removal and disposal of the old benchtop, and reconnection of plumbing and the cooktop.
A quote that leaves out templating, cut-outs or removal is not cheaper, it is incomplete, and the difference reappears as a variation later. Ask for the inclusions in writing. For the wider picture across materials, see our stone benchtop cost guide for Melbourne.
How to bring a porcelain quote down
Choose a standard colour over a premium full-body veined slab, keep to a simple edge profile, avoid unnecessary joins by planning the layout around slab sizes, and keep the existing cabinet footprint so the install is a straight swap. None of those compromise the surface itself. What you should not cut is templating and installation, which is where a porcelain job succeeds or cracks. Our affordable stone guide covers the same tactics across materials.
Frequently Asked Questions
How much do porcelain benchtops cost per square metre?
About $400 to $1,050 per square metre supplied and installed in Australia for standard work. The slab alone is roughly $350 to $550 per square metre. Premium brands and complex fabrication push published figures to $700 to $2,000.
How much does a porcelain benchtop cost for a whole kitchen?
A standard galley or L-shaped Melbourne kitchen commonly lands between $5,000 and $6,500 supplied and installed. Islands, waterfall ends and full-height splashbacks use more slab and more fabrication time, so they run higher.
Is porcelain cheaper than engineered stone or granite?
Porcelain sits close to granite to buy and below it to own, because it never needs sealing. Engineered stone is not a comparison any more, as the product was banned in Australia from 1 July 2024.
Why is porcelain fabrication more expensive than other stone?
Porcelain is extremely hard and comparatively brittle, so it needs diamond tooling, slower cutting and careful handling. A mitred edge or undermount cut-out takes longer than the same detail in granite. That labour separates a cheap quote from a sound one.
Does thickness change the price of a porcelain benchtop?
Yes, but not as expected. Thin 6mm porcelain costs less per slab but usually needs a substrate and more fabrication, so the installed price barely drops. 12mm and 20mm cost more to buy and install more simply as a benchtop.
What is not included in a cheap porcelain benchtop quote?
Watch for templating, removal and disposal of the old top, sink and cooktop cut-outs, edge profiling, joins, and plumbing reconnection. A quote missing these is incomplete rather than cheaper.
