20mm vs 30mm Quartz.
Which should you choose?

Ten millimetres sounds small, but it can noticeably change the proportions of your kitchen. Neither thickness is automatically better — the right choice depends on cabinetry, edge detail, design and budget.

At a glance

Think design first.
Not simply thicker = better.

20mm QuartzSlim & contemporaryA cleaner, lighter visual line that works especially well with modern and handleless cabinetry.
30mm QuartzMore substantialA thicker visible edge that can add visual weight to Shaker kitchens, larger islands and more traditional designs.
Edge detailPart of the decisionYour chosen thickness affects the proportions of bullnose, Ogee and other feature profiles. Decide thickness and edge together.
BudgetCompare the whole jobMaterial thickness can affect price, but slab yield, cut-outs, edges, splashbacks and installation can matter just as much.

Spend extra where
you can actually see it.

For a sleek modern kitchen, 20mm can look more deliberate than 30mm. For a substantial island or traditional kitchen, 30mm may suit the proportions better.

The better question isn't “Which is best?” It's “Which looks right in my kitchen, and is the extra spend worth it?”

specification.

Check material, thickness, edge profile, upstands, splashbacks, cut-outs, templating and installation before comparing two prices. A cheaper headline quote isn't necessarily the better-value installed job.
