Typical prices per square metre
These ranges come from published Australian quote guides for South Australia and are for supplied and installed benchtops. Treat them as a starting point. Your written quote depends on the slab you pick and the details of your kitchen.
| Material | Per m², installed | Typical 5–7 m² kitchen | Notes |
|---|---|---|---|
| Granite | $600 – $1,200 | $3,500 – $8,000 | Wide range of slabs, exotic granites cost more |
| Porcelain | $900 – $1,800 | $5,000 – $12,000 | Mitred edges add labour |
| Sintered stone | Similar to porcelain | Brand dependent | Thicker slabs mean fewer mitres |
| Marble | $800 – $2,500 | Varies widely | Calacatta and rare marbles at the top |

What pushes the price up or down
- The slab: the single biggest factor. Ask for two options at different price points.
- How much slab you use: an L-shape and an island can need two slabs even if the area is small.
- Edge profile: a simple pencil-round edge costs least; mitred and thick edges cost more.
- Waterfall ends: each end is extra slab and extra labour, and vein-matching adds more.
- Cut-outs: sinks, cooktops, tap holes and power outlets each add a charge. Undermount sinks need polished cut-outs.
- Splashbacks: a full-height stone splashback can be a big share of the price.
- Access and location: upstairs apartments and outer areas can add handling or travel costs.
- Removal: taking out and disposing of old benchtops is usually extra.
How to get an accurate quote
- Send a plan, sketch or photos with rough lengths and depths.
- Mark where the sink, cooktop and any island go.
- Say which material and colour you like, or your budget.
- Mention any waterfall ends, splashbacks or extra benches like the laundry.

Frequently asked questions
How much does a stone benchtop cost for an average kitchen in Adelaide?
A standard kitchen with 5–7 m² of benchtop often costs between about $2,500 and $8,000 supplied and installed, depending on the material. Large kitchens with islands, mitred edges and waterfall ends can cost $12,000 or more.
Is there a minimum charge?
Most fabricators have a minimum job charge, often around $1,800 to $2,400, because measuring, cutting and installing take similar time regardless of size. Small jobs like a single vanity cost more per square metre.
Is porcelain more expensive than granite?
Often, yes. Porcelain is usually priced higher per m² than standard granite because of the slab cost and the extra labour for mitred edges. Premium and exotic granites can cost more than porcelain.
Does the quote include removing my old benchtop?
Not always. Ask for removal and disposal to be listed separately. Removing old engineered stone needs extra care under current safety rules.
