Engineered timber flooring is a board with a top layer of real timber, called the lamella or veneer, over base layers of plywood or timber, as the Australian Timber Flooring Association (ATFA) describes it. Hybrid flooring has no real wood on its surface: it combines a rigid vinyl-based core with a printed timber look and a hard wear layer. Solid timber is one piece of hardwood, usually 19 mm thick, and can be sanded the most times.
- ATFA: engineered flooring has a lamella of solid timber over plywood or timber base layers; hybrid combines a rigid SPC core with a wear-resistant laminate-style face.
- Engineered veneers range from about 0.6 to 4 mm, and most engineered boards can be sanded one to three times (Embelton).
- Hybrid planks are often sold as waterproof, but Godfrey Hirst says not to lay them where there is a continual risk of excess moisture, and allows wet areas only for set ranges under strict conditions.
- Underfloor heating limits differ: Quick-Step says a maximum sub-floor surface temperature of 27°C; Godfrey Hirst says 26°C.
- What’s The Damage (October 2026), Sydney supply and install: solid $170–$320/m², engineered $125–$230/m², hybrid $63–$140/m².
What is engineered timber flooring?
Engineered timber flooring is a layered board with real timber on top. ATFA describes it as a lamella or veneer of solid timber, generally over base layers of plywood or timber blocks.
The layered base makes the board more stable than solid timber. ATFA says engineered and laminate floors are designed to greatly reduce how much boards move in width as humidity changes. Most engineered boards come pre-finished from the factory, so there is no sanding or coating on site.
The top layer is what you walk on and what can be sanded later. Embelton says veneers range from about 0.6 to 4 mm. ATFA notes that much engineered flooring has a lamella of at least 2.5 mm.
What is hybrid flooring?
Hybrid flooring is a rigid plank with a printed timber look and no real wood on its surface. ATFA says hybrid combines the features of SPC (stone plastic composite) flooring with the wear-resistant melamine face of laminate.
Premium Floors describes the layers as a protective wear layer, a decorative design layer, a rigid core typically made from PVC with mineral fillers such as limestone, and an attached acoustic underlay.
Laminate is different again. ATFA describes it as a photographic image of timber on a fibreboard core. Water-resistant laminate is not classed as waterproof.
Engineered vs solid vs hybrid flooring compared
Each floor suits different homes. This table sets out the main differences.
| Factor | Solid timber | Engineered timber | Hybrid |
|---|---|---|---|
| What it is | One piece of hardwood | Real timber top layer over plywood or timber layers | Rigid vinyl-based core, printed decor layer and wear layer |
| Top layer | Whole board; standard profiles are 19 mm thick (ATFA) | About 0.6 to 4 mm of timber (Embelton) | Printed image under a wear layer |
| Can it be sanded? | Yes, many times; NWFA says six to eight times over its life | Usually one to three times, depending on the top layer | No |
| Water | Not for wet areas | Not for wet areas | Core resists water, but joints and installation set the limits |
| Movement | Shrinks and swells with humidity | Moves less with humidity than solid | Expands and contracts with temperature (ATFA) |
| Underfloor heating | Check with the maker | Some products allowed; others not recommended | Godfrey Hirst allows hydronic, not electric radiant |
| Typical install | Nailed or glued to joists, battens or slab, sanded on site | Floated or glued, pre-finished | Floated, often with attached underlay |
| Sydney supply and install | $170 to $320 per m², typical $230 | $125 to $230 per m², typical $160 | $63 to $140 per m², typical $92 |

Is timber flooring waterproof?
No. Solid and engineered timber are not waterproof, and hybrid is water resistant at best in most real homes. Godfrey Hirst’s engineered timber installation guide says not to install timber flooring in wet areas or rooms with floor wastes, such as bathrooms, toilets and laundries.
Hybrid is where the marketing gets confusing. Quick-Step says all its hybrid vinyl components are 100% waterproof and that its joints are fully closed. Premium Floors warns that not all hybrid floors create a watertight seal between boards.
Godfrey Hirst says its hybrid flooring is impervious to moisture but should not be installed in areas with a continual risk of excess moisture or flooding, such as saunas or outdoor areas. It allows wet areas only for its Metropol and Apollo ranges, and only in small rooms under strict conditions.
Godfrey Hirst’s hybrid instructions allow only its Metropol and Apollo ranges in wet areas, and only Category 3 wet areas under AS 3740:2021. The room must be under 12 m², with no floor waste and no freestanding bath, and the edges sealed with silicone. Other brands set their own rules, so read the installation guide and warranty before laying any floor in a bathroom or laundry.
Can you sand and refinish engineered or hybrid floors?
Engineered timber can usually be sanded a few times, solid timber many times, and hybrid not at all.
- Engineered: Premium Floors says the real hardwood top layer can be sanded and refinished up to two or three times, depending on its thickness. Embelton says each sanding takes off about 1 mm.
- Solid: the US National Wood Flooring Association says most solid wood floors can be sanded six to eight times over their life.
- Hybrid and laminate: hipages says laminate, vinyl and other printed floor coverings should not be sanded. Damaged hybrid planks are replaced, not refinished.

Which floors work with underfloor heating?
Many engineered and hybrid floors can go over water-based (hydronic) heating, but the limits are strict and vary by brand.
- Quick-Step’s underfloor heating guide says the maximum surface temperature of the sub-floor is 27°C, with water at the boiler outlet no hotter than 50°C. Temperature should be raised about 5 degrees a day when first turned on.
- Godfrey Hirst’s guide says the slab surface should never exceed 26°C, and warns the floor can overheat under a heavy rug. It says Australian species engineered timber is not recommended over underfloor heating of any kind, and doing so voids the warranty.
- Premium Floors says glued-down engineered floors give the best heating efficiency, but its engineered Spotted Gum and Blackbutt are not compatible with underfloor heating.
- Godfrey Hirst says its hybrid can go over hydronic heating but never over electric radiant heating.
Which floor is best for apartments and strata?
Any of them can work in an apartment if the floor system meets your building’s acoustic rules. In NSW, installing or replacing hard floors is a minor renovation. The NSW Government says owners must provide an acoustic certificate to show sound insulation and get approval from the owners corporation first.
For new apartment buildings, NCC 2022 requires floors between units to have an impact rating (Ln,w) of no more than 62. Many by-laws set tougher targets for replacement floors, so ask your strata manager what yours needs.
Hybrid often comes with an attached acoustic underlay, and engineered boards can be laid over a separate acoustic underlay. What matters is the tested result for the whole build-up: board, underlay and your slab.
Which should you choose for a Sydney home?
Match the floor to the room, the subfloor and how long you plan to stay.
- Solid timber: suits houses with timber subfloors and owners who want a floor that can be sanded many times over decades.
- Engineered timber: suits slabs, apartments and renovations where you want real timber without on-site sanding.
- Hybrid: suits busy family areas, rentals and budgets where spills are common, as long as you follow the maker’s limits.
Sydney’s humid summers and sunny rooms matter too. Godfrey Hirst’s engineered timber guide asks for the room to stay between 18 and 27°C and 35 to 75% relative humidity before, during and after installation, and for boards to be protected from direct sunlight. Its hybrid guide sets the same range. Premium Floors says rooms with strong direct sun may see more expansion and contraction.

Frequently asked questions
Is engineered timber real wood?
Yes. The top layer you see and walk on is real timber, glued over base layers of plywood or timber. ATFA says this gives engineered flooring a real wood surface. The base layers make it more stable than solid boards, but the thinner timber layer means it can be sanded fewer times.
Is hybrid flooring better than laminate?
It depends on the room. ATFA says laminate has a fibreboard core and water-resistant laminate is not classed as waterproof, while hybrid uses a rigid vinyl-based core that is not affected by humidity. That makes hybrid the safer choice where spills are likely. Laminate often costs less: What’s The Damage puts it at a typical $75 per m² in Sydney, against $92 for hybrid.
Can you put hybrid flooring in a bathroom?
Only if the product’s instructions allow it. Godfrey Hirst allows only its Metropol and Apollo ranges in Category 3 wet areas, in rooms under 12 m² with no floor waste and no freestanding bath. Many other hybrid products are not rated for bathrooms. Laying a floor outside the maker’s rules can void the warranty.
Does hybrid flooring need to acclimatise?
Usually not, but follow the maker’s instructions. Godfrey Hirst says its hybrid generally does not need acclimatising, unless the boxes were exposed to temperatures under 5°C or over 50°C in the previous 12 hours. It asks for the room to stay between 18 and 27°C and 35 to 75% relative humidity before, during and after installation. ATFA says vinyl-based floors expand and contract with temperature, so very hot sunny rooms need extra care with expansion gaps and blinds.
Can engineered timber go over concrete?
Yes. Engineered boards are often floated over an underlay or glued directly to a concrete slab. The slab must be dry and flat. Godfrey Hirst says that where the slab has not been moisture tested, a continuous damp-proof membrane such as 200 micron plastic sheet must be laid. In apartments, you will also need an acoustic underlay that meets your by-laws.
