20mm Slabs

20mm Stone Slabs in Newcastle

These are the 2cm slabs currently on the floor at our Mayfield West showroom — the bulk of our range, across quartzite, dolomite, granite, marble and limestone. 20mm is the standard thickness for kitchen benchtops, bathroom vanities, splashbacks and wall cladding: it's lighter for your stonemason to handle, suits most cabinetry, and where you want a thicker-looking edge your stonemason can laminate a strip to build it up. Each page shows the full slab and close-ups of that exact block.

When to choose 20mm over 30mm

Choose 20mm for splashbacks, cladding, vanities and benchtop runs where the edge sits over cabinetry, and whenever you want the widest choice of colours. If the edge is the feature — an island, a waterfall end, a bar — have a look at our 30mm slabs as well. Our choosing stone guide walks through it, or book a viewing and compare both side by side.

Common Questions

Is 20mm thick enough for a kitchen benchtop?

Yes — 20mm is the most common benchtop thickness in Australia. Your stonemason will add support where overhangs are generous.

Can I see the 20mm slabs in person?

Yes. Our showroom is at 1/5 Coal Wash Drive, Mayfield West — open by appointment, 7 days a week, weekends welcome.
