Vinyl Flooring Thickness: How to Choose the Right One

Vinyl flooring thickness in Australia ranges from about 2 mm for sheet vinyl up to 8 mm for SPC hybrid planks. For most homes the sweet spot is 5-6 mm luxury vinyl plank or a 6-8 mm SPC hybrid — thick enough to hide minor subfloor bumps and feel solid underfoot, without the cost or install fuss of the thickest commercial-grade products. The number on the box isn’t the whole story though. The wear layer matters more than total thickness, and the right pick depends on what’s under the floor and what walks on top of it.

Total thickness vs wear-layer thickness

Two numbers matter on a vinyl spec sheet. Total thickness is the full plank — usually 2 mm for sheet vinyl, 4-5 mm for glue-down or click-lock LVP, and 6-8 mm for SPC hybrid. Wear-layer thickness is the clear protective top film, measured in mils (thousandths of an inch) or millimetres. A 12 mil (0.3 mm) wear layer is the minimum we’d recommend for residential use; 20 mil (0.5 mm) is the standard for busy households and rental properties; 28 mil (0.7 mm) is light-commercial grade.

You can have a 5 mm plank with a 12 mil wear layer that scratches easily, or a 4 mm plank with a 22 mil wear layer that survives a decade of dog claws. Always ask for both numbers, not just the total.

Thickness by vinyl type

  • Sheet vinyl, 2-3 mm: the cheapest option, comes in rolls. Surface is fully waterproof but a thin product that telegraphs every subfloor lump. Suits laundries, sheds, and rentals on a tight budget.
  • Glue-down LVP, 2-3 mm: commercial fit-outs and high-traffic spaces. Bonded directly to a level subfloor, so the thickness doesn’t need to do structural work.
  • Click-lock LVP, 4-5 mm: floats over an underlay. Good for retrofits over existing tile or timber. Wear layer is the deciding factor at this thickness.
  • SPC hybrid, 6-8 mm: stone-polymer core with pre-attached IXPE underlay. The thickest, most rigid option. Hides subfloor bumps, feels solid underfoot, and the core is fully waterproof. This is what we sell most of for Australian residential.

How traffic should drive the choice

For a quiet bedroom, a 4 mm plank with a 12 mil wear layer is plenty. For a hallway, kitchen or open-plan living area, step up to 6 mm SPC hybrid with at least a 20 mil wear layer. For a holiday rental or a household with large dogs, 8 mm SPC with a 22-28 mil wear layer is the safer call — the extra mass dampens footfall and the thicker top film resists scratching.

Kitchens are the room people most often under-spec. Standing at a benchtop for 20 minutes prepping dinner is exactly the kind of repeated point loading that wears a thin plank. Our best flooring for kitchens guide goes deeper on which vinyl specs hold up around water and dropped pans.

Subfloor condition and underfoot feel

Thicker vinyl forgives more subfloor sins. A 2 mm sheet vinyl shows every divot and high spot. A 6-8 mm SPC plank with an attached underlay rides over minor variation up to about 3 mm in 2 metres. That said, no vinyl thickness fixes a properly out-of-level slab — the planks will sit flat but the floor will still feel sloped.

If you’re laying over concrete, the substrate prep matters more than the plank thickness — see our notes on how to lay vinyl on a concrete floor for the moisture-test and self-leveller side of it. And for click-lock vinyl, whether you need separate underlay depends on what’s already attached: our do you need underlay for vinyl flooring guide covers when to skip it.

What about waterproofing?

Every vinyl product has a waterproof surface, but only SPC hybrid has a fully waterproof core. That distinction matters in laundries, kitchens and any room where water might pool at the seams. Total thickness doesn’t change waterproof status — a 2 mm sheet vinyl is just as surface-waterproof as an 8 mm SPC plank. The difference is what happens to the substrate if water reaches it. For a full breakdown, our waterproof flooring options pillar covers which products handle which scenarios.

The short answer

For most Australian homes, 6 mm SPC hybrid with a 20 mil (0.5 mm) wear layer is the right pick — it covers bedrooms, hallways, living areas and kitchens without changing product across the floor. Step up to 8 mm with a 22 mil wear layer if you’ve got large pets, kids, or a less-than-flat subfloor. Drop down to 4-5 mm LVP only if budget is the deciding factor, and don’t go below a 12 mil wear layer regardless of total thickness. Bring a sample home, walk on it, drop something on it, and check how the colour reads against your skirtings before you commit.
