Plywood vs particle board cabinets: which is better?
For a kitchen, plywood. Plywood is thin layers of real wood glued with the grain crossed, so it holds a screw, carries weight on a shelf without sagging, and survives the occasional leak far better than particle board. Particle board is wood chips and resin pressed into a sheet: it costs less, which is why it turns up in low-priced cabinets, usually under a paper, thermofoil or melamine wrap, but it swells and crumbles once water gets in. Every RTA Cabinets Plus cabinet has a plywood box and 3/4" plywood shelves with real paint and stain finishes, priced below comparable cabinets with the same build.
How the two materials behave in a kitchen.
| Plywood | Particle board | |
|---|---|---|
| What it is | Thin layers of wood veneer, glued with the grain of each layer crossed. | Wood chips and sawdust bonded with resin and pressed into a sheet. |
| Water | Resists swelling. A spill or a slow drip under the sink is survivable. | Swells, softens and crumbles once water reaches the core, and does not recover. |
| Screws and hinges | Holds a screw firmly, and holds it again if a hinge is reset. | Holds a screw at first; a stripped hole is hard to fix. |
| Shelves | Carries plates and pans without sagging over time. | Sags under steady weight, especially on wider shelves. |
| Weight | Lighter for its strength. | Heavier for the same size. |
| Price | Costs more to make. | Costs less, which is why budget cabinets use it. |
How to tell which one you are buying.
A finished cabinet hides its core, so read the spec and check the parts that matter most.
- Look at an edge
- Plywood shows thin stripes of layered wood. Particle board shows a speckled edge of chips.
- Read the whole spec
- Some cabinets use plywood for the sides and particle board for the back, bottom or shelves. Ask about every part, not just the box.
- Check the sink base
- It is the cabinet most likely to see water. If anything in a kitchen should be plywood, it is this one.
- Ask about the finish
- A wrap of paper, thermofoil or melamine usually means a particle board or MDF core underneath. Real paint or stain usually means real wood.
Plywood, from the box to the shelves.
- The box: plywood on every cabinet, with a solid wood face frame.
- The shelves: 3/4" plywood, thick enough to carry a full stack of plates.
- The joint: the panels lock together on a licensed click-together system, with 100% tool-free box assembly. Anything wood-to-wood clicks together, no tools, no glue, no screws.
- The price: below comparable cabinets with the same build, and printed on every product page.
What people ask next.
Is plywood better than particle board for kitchen cabinets?
Yes, for most kitchens. Plywood holds screws better, carries more weight on a shelf, and resists swelling when it gets wet, which matters most under a sink. Particle board costs less and is fine for furniture that stays dry.
Are plywood cabinets worth the extra cost?
For a kitchen, usually. The places a cabinet fails, a wet sink base, a sagging shelf, a stripped hinge screw, are the places plywood holds up and particle board does not. RTA Cabinets Plus cabinets are plywood and priced below comparable cabinets with the same build.
How can I tell if a cabinet is plywood?
Look at an unfinished edge: plywood shows thin layers of wood, particle board shows chips. Then read the spec for every part, because some cabinets mix plywood sides with a particle board back, bottom or shelves.
What about MDF?
MDF (medium density fiberboard) is finer and smoother than particle board and takes paint well, so it is common in door panels. Like particle board, it does not like water, which makes it a poor material for a cabinet box.
Are RTA Cabinets Plus cabinets plywood?
Yes. Every cabinet has a plywood box and 3/4" plywood shelves, with a solid wood face frame and a 5/8" solid wood dovetail drawer box.
