Cabinet box material is the question every customer asks within the first 10 minutes. The short version: all-plywood is better in any Brooklyn kitchen that ever sees moisture or weight, particleboard is fine in a dry rental cabinet that nobody will care about in 5 years.
Key Takeaways
- All-plywood box is roughly 15 to 25 percent more expensive than particleboard for the same line.
- Plywood holds screws better, resists water better, weighs less.
- Particleboard with melamine is fine for upper cabinets and dry rooms.
- Sink base should always be plywood, particleboard fails when (not if) the trap leaks.
- Every line we recommend uses all-plywood. We will tell you if a quote sneaks particleboard in.
Contractor Insight
The 30-second showroom test: knock on the side panel of a cabinet. Plywood has a higher, more solid pitch. Particleboard sounds dull and hollow. Then look at an exposed edge, plywood shows layered veneer, particleboard shows compressed flakes under tape.
Brooklyn-specific reasons plywood matters
Old Brooklyn plumbing leaks. Older buildings have settled, so trap connections sit on a slight angle and seep. Sink-base water damage is the single most common reason a 5-year-old cabinet looks tired. Plywood swells but recovers. Particleboard turns to oatmeal.
What you are actually paying for
The differences look small on a spec sheet but show up in year 3.
Screw holding strength
Plywood holds screws 30 to 50 percent better than particleboard. Every drawer slide and every hinge depends on this. Particleboard hinges loosen, drawer slides start dragging.
Moisture resistance
Plywood swells when wet but dries back to roughly its original dimension. Particleboard absorbs water, swells permanently, and starts to crumble at the edges.
Weight
Plywood is lighter per cubic foot. A 30-inch sink base in plywood is about 8 to 12 pounds lighter, which matters when an installer is lifting it onto a stand alone.
Warpage
Particleboard side panels can bow under heavy granite tops if the bracing is undersized. Plywood stays straight.
Side by side, the practical differences
Same cabinet, two box materials, year-3 outcomes.
| Test | All-plywood | Particleboard |
|---|---|---|
| Hinge holds for 10+ years | Yes | Often loosens |
| Survives a sink trap leak | Usually yes | No, swells and crumbles |
| Drawer slide screws strip | Rare | Common after 5 years |
| Side panel bows under granite | No | Sometimes |
| Weight per 30-inch base | 55 to 65 lbs | 65 to 80 lbs |
| Recyclable | Yes | No (resin content) |
| Smell on install day | Low formaldehyde | Higher (use CARB-2 minimum) |
- If a quote does not say all-plywood, assume particleboard.
- Melamine-faced particleboard is what most builder-grade cabinets are.
- All-plywood is the default on every line we recommend.
How to check what is in your quote
Ask the supplier these three questions in writing.
- 1
What is the side panel?
Answer should be: 1/2-inch plywood with finished interior.
- 2
What is the back panel?
Answer should be: 1/4-inch or 3/8-inch plywood, not cardboard or hardboard.
- 3
What is the floor of the sink base?
Answer should be: 5/8 or 3/4-inch plywood. Particleboard floor is a no-go for the sink base.
Upcharge for plywood
Typical 12-cabinet kitchen, plywood vs particleboard.
| Item | Particleboard | All-plywood | Upcharge |
|---|---|---|---|
| 12-cabinet kitchen, supplied | $3,800 to $5,200 | $4,500 to $6,200 | $700 to $1,000 |
| Sink base alone | $210 | $265 | $55 |
| 10-year repair savings (est.) | n/a | n/a | Pays for itself |
We do not sell particleboard for any cabinet that holds a sink or a heavy stone top, period.
Mistakes to Avoid
- Believing a salesperson who says all particleboard is the same, it isn't.
- Skipping the spec sheet, ask for it in writing before you sign.
- Choosing particleboard for the lower cabinets to save money, then putting granite on top.
- Assuming an expensive cabinet is automatically all-plywood, some premium lines still use particleboard backs.
- Throwing out the spec sheet, you need it for warranty claims.
FAQs
Is plywood worth it for upper cabinets only?+
Less critical. Uppers do not see water or carry stone. Plywood is still nicer and worth the upcharge if it is small, but it is not a deal-breaker.
What about MDF doors?+
MDF doors are fine. They take paint better than wood and do not warp. The question is about the box, not the door.
How can I tell what I already have?+
Open the sink-base door and look at the bottom floor with a flashlight. Layered veneer = plywood. Brown speckled compressed material = particleboard.
