Hybrid flooring is a category, not a single product. Walk into a showroom and you’ll see planks labelled SPC, RCB, WPC, “with attached underlay”, or “100% waterproof” — and they’re not all the same floor. This guide explains what each type actually is, where it suits, and how to pick between them. For a shortlist of ranges we stock, see our roundup of the best hybrid flooring brands in Australia.
What “hybrid” actually means
Hybrid flooring is a rigid plank with a printed timber-look wear layer, designed to be installed as a click-lock floating floor. The key word is rigid — unlike traditional vinyl planks, hybrids don’t flex with your subfloor, which is why they hold their joins under furniture and foot traffic. The differences between hybrid types come down to what’s in that rigid core.
SPC (Stone Polymer Composite)
SPC is the densest and most stable of the hybrid cores. The core is a mix of limestone powder and PVC, pressed into a board that’s fully waterproof from top to bottom. SPC handles temperature swings, won’t expand in a hot summer room, and resists dents from dropped pans and dog claws better than softer cores. The trade-off is that it’s harder underfoot — you feel the rigidity through your shoes, and sound transmission to a room below can be louder than with a softer plank.
SPC suits kitchens, laundries, downstairs living areas on slab, and any space that sees regular spills. Most SPC ranges come around 4-6 mm thick with a pre-attached IXPE acoustic underlay.
RCB (Rigid Core Board)
RCB is the broader category that covers rigid hybrids that aren’t strictly stone-composite. RCB cores are slightly softer underfoot than SPC and a bit more forgiving over imperfect subfloors — they bridge minor undulation that SPC would telegraph through. The wear layer and waterproofing are similar, but the acoustic feel is closer to traditional vinyl. If you want the practical upsides of hybrid with a bit more give underfoot, RCB is the call.

WPC (Wood Polymer Composite)
WPC uses a wood-flour and plastic composite core instead of stone. The result is a thicker, lighter, warmer plank that’s softer underfoot than SPC. WPC is a fair pick for bedrooms or living rooms where comfort underfoot matters more than maximum dent resistance. It’s still waterproof, but the core is less dense, so heavy point loads (piano legs, stiletto heels) can leave marks more easily than on SPC. WPC has fallen out of favour in the Australian market over the last few years as SPC has dropped in price, but you’ll still see it in some ranges.
Hybrid with attached underlay
Most modern hybrid planks ship with a pre-attached IXPE foam or cork underlay on the back of each board. This is a feature, not a separate product type — you’ll see SPC, RCB and WPC ranges all available with attached underlay. The benefit is one less install step and a small acoustic improvement. The catch: if your body corporate spec calls for a thicker acoustic underlay (common in apartments), the attached layer alone usually won’t meet it, and you’ll need to add a separate acoustic underlay on top.
Fully waterproof hybrids
All rigid hybrids are surface-waterproof, but “100% waterproof” usually refers to the core itself being unaffected by submersion — meaning a plank that’s been sitting in standing water for 24 hours won’t swell or delaminate. This matters for laundries, downstairs entries, and any home in a flood-prone area. If waterproofing is your priority, our guide to what flooring is waterproof walks through the full set of options including hybrid, SPC and tile.
Which type suits which room
- Kitchen, laundry, downstairs slab: SPC. Density and waterproofing matter most here.
- Open-plan living over an uneven subfloor: RCB, or SPC with self-levelling done first.
- Bedrooms, upstairs living: RCB or WPC for comfort underfoot, or SPC with a thicker acoustic underlay.
- Apartments: Check your body corporate acoustic spec before picking. Attached underlay rarely meets the rating on its own.
- Flood-prone ground floors: SPC, ideally with the joints sealed.
Budget and the short answer
Pricing across the three cores has compressed in the last few years. SPC used to carry a premium over WPC and RCB; today most mid-range hybrid ranges are SPC, and pricing is driven more by wear-layer thickness and brand than by core type. For a current view of what to budget per square metre supplied and installed, see the hybrid flooring cost guide.
The short answer for most Australian homes: an SPC hybrid around 5-6 mm thick with a 0.5 mm wear layer and pre-attached IXPE underlay covers kitchens, living areas and laundries comfortably. Step up to a thicker wear layer for high-traffic commercial use, or sideways to RCB if comfort underfoot matters more than maximum density. Bring a sample home, lay it next to your kitchen joinery, and walk on it in socks before you commit. We carry the major hybrid ranges across our Sydney and Brisbane showrooms.
