Walk into any kitchen showroom and you will hear the same four words: particleboard, MDF, plywood, timber. Nobody explains what they actually mean for your kitchen. This guide compares kitchen cabinet materials on the three things that decide whether a kitchen lasts — moisture, strength and cost.
The short answer
For most Melbourne kitchens, the sensible build is a moisture-resistant particleboard carcass with MDF doors finished in two-pack or laminate. Plywood carcasses are stronger and lighter but cost noticeably more. Solid timber belongs on doors and shaker frames, not on carcasses — it moves with humidity and will eventually twist a big flat panel.
Material matters less than build quality. A 16 mm board with proper edge banding and good hinges will outlast an 18 mm board with bare edges under the sink.
What is actually in a kitchen cabinet?
A cabinet is three separate decisions, and they rarely use the same material:
- The carcass — the box. It never gets seen once the kitchen is in, so it is chosen for strength and moisture resistance, not looks.
- The doors and drawer fronts — everything you see and touch. This is where finish quality shows.
- The hardware — hinges, runners, legs. The part that fails first if it is cheap.
When a quote says “solid timber kitchen”, it almost always means timber doors on a board carcass. That is normal and usually the right call.
Cabinet carcass materials compared
| Material | Moisture resistance | Screw holding | Relative cost | Best for |
|---|---|---|---|---|
| Standard particleboard | Poor once the edge is exposed | Fair | $ | Dry runs, low-use cabinets |
| Moisture-resistant (MR) particleboard | Good | Fair to good | $$ | Most kitchens, especially sink and dishwasher runs |
| Plywood | Good | Excellent | $$$ | Long spans, heavy stone, tall pantries |
| MDF | Poor unless MR grade | Good in the face, weak in the edge | $$ | Doors and panels rather than boxes |
The cabinets we stock use a 16 mm heavy-duty particleboard carcass with an off-white internal finish, which is the standard used across most Australian flat-pack and mid-range kitchens. You can see the full specifications on each product in our kitchen cabinets range.
Cabinet door materials compared
Doors are where your budget is most visible, so it pays to understand the four common options.
- MDF with a two-pack painted finish. MDF is machined, primed and spray-painted. It gives a seamless colour with no visible grain or joins, and it can be colour-matched to almost anything. Our doors are 18 mm E1 MDF with a two-pack gloss or matt finish. If you are weighing this up against other finishes, our guide to two-pack kitchen cabinets in Melbourne goes into the detail.
- Laminate or melamine. A decorative surface pressed onto board. Hard-wearing, the cheapest per door, and modern woodgrain laminates look far better than they used to. The edge banding is the weak point — check it is thick and well glued.
- Thermolaminated vinyl. A vinyl film vacuum-wrapped over shaped MDF. Good for profiled and shaker doors at a lower price than paint. Keep it away from ovens without a heat deflector, as sustained heat can lift the film.
- Solid timber. Usually a timber frame with a board centre panel. Beautiful, repairable, and the most expensive. It will move slightly with Melbourne’s humidity swings, which is why full solid slab doors are rare.
What to check before you buy
Material names on a quote tell you less than these six things. Run through them on any kitchen you are comparing:
- Board thickness. 16 mm is the standard for carcasses; thinner boxes flex under stone.
- Formaldehyde grade. Look for E1 or E0. E1 is the common Australian standard for indoor board products; E0 is lower again.
- Edge banding. Every exposed edge should be banded, especially the cut-outs under the sink. Bare board plus one leak equals a swollen cabinet.
- Hinges. Soft-close should be standard, not an upgrade. Ours are soft-closing DTC hinges. Ask for the brand, not just the words “soft close”.
- Adjustable legs. They let the installer level cabinets on an uneven floor, which almost every older Melbourne home has.
- Back panel. A thicker, captured back panel keeps the box square. A thin stapled-on back does not.
These are the same checks a good tradesperson makes, and they are a large part of why quotes differ so much. Our piece on the difference between a cabinet maker and a carpenter explains who does what.
How much does material choice change the price?
Moving from laminate doors to two-pack paint is usually the single biggest jump in a cabinet quote. Changing the carcass from MR particleboard to plywood adds cost across every box in the kitchen, so it lifts the total more than people expect.
Because we import our own cabinetry and sell direct from our Clayton South warehouse, you are paying for the board and the hardware rather than a chain of mark-ups. That is also why our flat-pack kitchens can use decent materials at a price most showrooms reserve for entry-level boards.
If you are deciding between a standard size range and a fully made-to-measure kitchen, read custom kitchen cabinets: how to get a perfect fit before you commit.
Seeing the materials in person in Melbourne
Board samples photograph badly. Gloss looks flat on a screen, and woodgrain laminates read completely differently under kitchen downlights than they do in daylight. It is worth handling the doors before you choose.
Our showroom and warehouse are at Clayton South, which is an easy run for most south-eastern suburbs — we regularly supply kitchen and bathroom renovations in Clayton and the surrounding areas. Bring your measurements and you can compare finishes and get pricing in the same visit.
Frequently asked questions
Is particleboard good enough for a kitchen?
Yes, provided it is moisture-resistant grade and every exposed edge is banded. The vast majority of Australian kitchens, including many expensive ones, use particleboard carcasses.
Is plywood worth the extra cost?
It is worth it for tall pantries, long unsupported spans and very heavy stone benchtops, where its screw holding and lighter weight genuinely help. For a standard kitchen, the money is usually better spent on doors and hardware.
What does E1 mean on a cabinet spec?
E1 is a formaldehyde emission grade for board products. It is the standard used for indoor furniture and cabinetry in Australia. E0 is a lower-emission grade again.
Which cabinet material is best around the sink and dishwasher?
Moisture-resistant particleboard or plywood, with fully banded edges and sealed cut-outs. This one run does more damage over a kitchen’s life than anywhere else, so it is worth specifying properly.
Can I mix materials in one kitchen?
Yes, and most people do. A common approach is MR particleboard carcasses throughout, two-pack doors on the main run, and a timber or laminate feature on an island.
