Short answer: the flooring types that are genuinely waterproof are SPC hybrid, luxury vinyl plank (LVP), porcelain and ceramic tile, sheet vinyl, and properly sealed polished concrete or epoxy. Everything else, including most laminates and all engineered or solid timber, is water-resistant at best. For Australian homes, the practical pick for a wet zone or whole-house waterproof floor is SPC hybrid or porcelain tile.
Waterproof vs water-resistant: what the labels actually mean
Flooring brands use “waterproof” and “water-resistant” loosely. A useful working definition: a floor is waterproof if standing water can sit on it for 24 hours and the plank, tile or sheet itself does not swell, warp or delaminate. Water-resistant means the surface sheds spills if you wipe them up promptly, but the core or substrate will fail under prolonged contact.
The product itself is only half the story. Joints, perimeter sealants, the underlay and the subfloor all sit underneath the waterproof layer. A waterproof plank over a particleboard subfloor still gives you a wet, ruined subfloor if water finds a way through a seam. That is why bathrooms and laundries get tile with proper waterproof membranes, and why we steer renovators toward SPC hybrid in kitchens and living areas where spills happen but the room isn’t fully wet.
SPC hybrid flooring
SPC stands for stone plastic composite. The core is a dense limestone-and-PVC blend that does not swell when it gets wet. Planks are typically 6-8 mm thick with a pre-attached IXPE acoustic backing and a 0.3-0.7 mm wear layer. Click-lock joints, usually a 5G or 2G system, lock the planks together without glue.
Because the core is mineral-based rather than wood-based, an SPC plank can be submerged for hours and come out dimensionally the same. That doesn’t make the floor system fully waterproof — water can still wick through joints to the subfloor — but the plank itself is the most water-stable timber-look product on the Australian market. It’s what we’d recommend for kitchens, laundries (above-floor, not in-shower), entries, and whole-home installs in flood-prone areas.

Luxury vinyl plank (LVP and LVT)
LVP is a flexible PVC plank, usually 4-6 mm thick. The plank itself is fully waterproof because it’s solid vinyl all the way through. There are two install methods worth knowing about: glue-down (each plank bonded to the substrate) and click-lock floating (planks lock to each other). Glue-down has tighter seams and copes better with heavy rolling loads. Click-lock is faster to install and easier to repair plank-by-plank.
LVP is the right call when you want a thinner profile than SPC hybrid (matching a tiled doorway threshold, for example), or when you need a more flexible plank that can sit over a slightly imperfect slab. It’s softer underfoot than SPC but also more prone to indentation from heavy furniture point loads.
Porcelain and ceramic tile
Tile is the original waterproof flooring and still the right answer for full wet zones. Porcelain is denser and lower-porosity than ceramic, which makes it the better pick for floors and any tile that will see standing water. Glazed porcelain has a water absorption rate below 0.5 percent, which is effectively zero.
The waterproof part of a tiled floor is actually the membrane underneath, not just the tile. In Australian bathrooms the waterproof membrane has to comply with AS 3740, which means a licensed waterproofer, a certificate, and a specific lap-up height onto walls. Tile sits on top of that membrane. Done properly, this is the only flooring system rated for full bathroom and shower use.
Tile is the obvious pick for bathrooms, laundries, mudrooms and outdoor patios. It’s also the right answer for a kitchen floor in a heritage home where you want a cooler, harder-wearing surface than vinyl. For more on the kitchen-specific tradeoffs, see our best flooring for kitchens guide.
Sheet vinyl
Sheet vinyl gets dismissed as old-fashioned, but for laundries and rental kitchens it remains genuinely waterproof in a way click-lock products are not. Because the sheet is one continuous piece, there are no plank-to-plank joints for water to wick through. The only seams are at the room edges and where two rolls meet, and those can be heat-welded into a continuous, fully sealed surface.
Modern commercial sheet vinyl runs 2-3 mm thick with embossed timber and stone prints that look better than the sheet vinyl most people remember. The downsides: you can’t replace one section if it gets damaged, and the install needs a smooth substrate because every imperfection telegraphs through.
Polished concrete and epoxy
Polished concrete is water-resistant when sealed with a penetrating densifier and a topical sealer, and effectively waterproof when finished with a polyurethane coat. The look is industrial and best suits open-plan living, basements, garages and warehouse-conversion homes. It’s hard underfoot and unforgiving on dropped glassware, but the lifespan is measured in decades.
Epoxy is a poured liquid coating that cures into a seamless, fully waterproof surface. It’s most common in garages and commercial settings because the resin smell during cure is intense and the install needs proper substrate prep. The finished floor is genuinely waterproof, chemical-resistant, and easy to hose down.
What to avoid in wet areas
- Solid hardwood: real timber absorbs water, swells, and cups. There is no Australian hardwood floor rated for wet zones.
- Engineered timber: the real-timber lamella has the same problem as solid. Most engineered ranges are rated water-resistant at the surface only, not waterproof.
- Standard laminate: the HDF core swells permanently when water reaches it through a joint. Some “waterproof laminate” ranges exist but the warranty fine print usually limits the claim to surface spills, not standing water.
- Carpet: traps moisture, grows mould, and is hard to dry once it’s saturated. Skip in any room that could see a leak.
How to pick the right waterproof floor for your home
Match the product to the wetness of the room, not the other way around. For full wet zones (bathrooms, internal laundries with floor wastes, pool surrounds), use tile over a compliant waterproof membrane. For semi-wet zones (kitchens, mudrooms, entry from a wet exterior), SPC hybrid is the modern default. For living areas and bedrooms in a flood-prone home, SPC hybrid again, because it can be lifted and dried out if the worst happens — covered in more detail in our best flooring for a flood-prone house guide.
Pet households are the other common waterproof use case. The plank doesn’t just need to handle spills — it needs to cope with accidents that sit overnight. We’ve covered that specific question in is vinyl flooring pee-proof.
If you’re not sure which product fits your room, bring a floor plan into our Sydney or Brisbane showroom and we’ll walk you through the options against your subfloor, your wet areas, and your budget. Most renovators land on a mix — tile in the bathroom, SPC hybrid through the rest of the house — and that combination is what we install most weeks of the year.
