Cabinet materials: MDF, plywood, solid wood, and which countertop

What cabinet boxes, doors and countertops are made of, what each material is good and bad at, and the questions to ask before you choose.

A cabinet is three different decisions

People talk about "wood cabinets" or "MDF cabinets", but every cabinet is really three parts: the box (the sides, bottom and back you mostly never see), the doors and drawer fronts you see every day, and the hardware that opens and closes them. Each part can use a different material, and the best choice for one is often not the best for another.

Cabinet boxes: plywood, particleboard or MDF

The box carries the weight of the countertop and everything inside it.

MaterialGood atWatch out for
PlywoodStrong for its weight, holds screws well, more forgiving if it gets a little wet.Costs more. Edges must be finished or banded.
Particleboard / melamineVery flat and stable, easy to keep clean, the most common box material.Heavy. Swells if water gets into an exposed edge, which matters most under the sink.
MDFVery smooth and stable, takes paint well, good for exposed panels.Heavy, and swells if water gets in.

All three can make a good cabinet when the joinery, edge banding and installation are done properly. Ask what the box is made of, and especially what is used under the sink.

Doors and drawer fronts

  • Solid wood: real grain that can be stained. Wood moves with humidity, and Ottawa’s dry winters and humid summers are hard on it. On painted five-piece wood doors, that movement can show as hairline cracks in the paint at the joints.
  • MDF: the usual choice for painted doors. It does not move with the seasons, so paint stays smooth. It cannot be stained like wood.
  • Wood veneer: a thin layer of real wood over a stable core. It gives the look of wood on flat slab doors without the movement of solid wood.
  • Laminate and melamine: durable and easy to clean, in solid colours and wood looks, at a lower price.
  • Thermofoil (vinyl wrapped over MDF): an inexpensive option, but it can lift or peel near heat sources such as an oven or a toaster.

Painted, stained or natural

Painted cabinets give a clean, solid colour and show chips more than stained wood does. Stained and clear-coated wood shows the grain and hides small marks. Two-tone kitchens, for example painted perimeter cabinets with a wood island, are common and let each part use the finish that suits it.

Hardware matters more than people expect

You open drawers and doors thousands of times a year. Full-extension drawer slides let you reach the back of the drawer, and soft-close hinges and slides stop doors from slamming. Good hardware often makes a bigger daily difference than the box material.

Countertops compared

MaterialGood atWatch out for
QuartzEngineered stone. Non-porous, no sealing, consistent colour.Do not put hot pans directly on it: the resin can scorch. A Toronto guide lists it at $70 to $140 per square foot.
GraniteNatural stone. Each slab is unique and it handles heat well.Needs sealing from time to time to resist stains.
Porcelain / sintered stoneVery resistant to heat, scratches and UV. Thin, modern profiles.Edges can chip if hit. Needs a fabricator who knows the material.
LaminateThe lowest cost, many colours and patterns.Not heat-resistant, visible seams, and most do not suit an undermount sink.
Wood / butcher blockWarm look, can be sanded and refinished.Needs regular oiling, and care around the sink.

How to choose

  • Painted look: MDF doors are the safest choice.
  • Wood grain: solid wood or wood veneer, stained or clear-coated.
  • Busy family kitchen: put the budget into drawers, hardware and a countertop you do not have to baby.
  • Bathroom vanities: moisture is the enemy, so ask about the box material and edge sealing.
  • Whatever you choose, get it in writing before production, so the cabinets that arrive are the ones you approved.

FAQ

Common questions

Another question? Call or text 613-796-6155.

Is plywood better than particleboard for cabinet boxes?

Plywood is stronger for its weight and handles a little moisture better, so many people prefer it under the sink. Well-made particleboard boxes are flat, stable and very common. Joinery, edge banding and installation matter as much as the sheet material.

Why do painted wood cabinet doors crack at the joints?

Solid wood expands and contracts with the seasons. On five-piece doors, that movement can open hairline cracks in the paint where the frame pieces meet. MDF doors do not move like that, which is why they are the usual choice for painted cabinets.

Can I put a hot pan on a quartz countertop?

It is best not to. Quartz contains resin, which can scorch or discolour under a hot pan. Use a trivet.

Can I mix materials in one kitchen?

Yes. Painted cabinets with a wood island, or wood veneer tall units with painted lowers, are common choices.
