Cabinets are the single biggest line item in a kitchen renovation. They are also where homeowners try hardest to save money. The math on that decision is worse than people think.
The money saved on cheap cabinets today usually buys a full replacement in 5 to 8 years, and a replacement costs far more than the original upgrade would have. That is not me being dramatic. That is what I quote when the homeowner calls me back in 2030 because the doors are sagging and the boxes around the dishwasher have swelled.
Here is what is actually inside cheap cabinets, what is inside good ones, and how to tell at the showroom.
The box: plywood vs particleboard
The box is the part you do not see. Sides, bottom, top, back. It carries the weight of the doors, drawers, dishes, and counter. It is the part that has to last.
Cheap cabinets are made from particleboard or thin MDF. Particleboard is sawdust and glue compressed into a sheet. It holds screws poorly. It cannot get wet (sawdust and water = sponge). It is brittle. Drop a glass into the back of an MDF cabinet and the corner cracks. Spill water in there once and the bottom puffs up like a sponge cake.
Good cabinets are 5/8 or 3/4 plywood. Plywood is layers of real wood with the grain alternating. It holds screws. It tolerates moisture. It carries weight without sagging. It costs more, but a plywood box lasts the life of the kitchen, which is 25 to 40 years.
How to tell at the showroom: open the cabinet. Look at the edge of the bottom shelf. If you see speckled brown sawdust pressed together, that is particleboard. If you see thin striped layers, that is plywood. The salesperson will tell you it is "the same thing." It is not.
The doors: solid wood vs MDF wrap
Doors get hands on them every day. Children swing on them. Steam from the dishwasher hits them. Cleaner gets sprayed on them.
Cheap doors are MDF wrapped in vinyl or thermofoil, or MDF with a sprayed finish. The vinyl peels off in 3 to 6 years where it gets warm (next to the oven, above the dishwasher). The sprayed finish on MDF chips along the edges where the moulding meets the panel. Once the chip starts, the MDF behind absorbs moisture and swells.
Good doors are real wood (maple, oak, walnut, cherry) with a sprayed catalyzed lacquer or 2K polyurethane finish. The wood does not delaminate because there is nothing laminated. Chips can be touched up. The finish is harder than the typical kitchen abuse can hurt.
The next-step-up are MDF doors with high-quality painted finishes (catalyzed paint, not house paint). These can be excellent for painted-shaker looks. The trick is the finish system. A real cabinet shop sprays in a temperature-controlled booth and bakes the finish. A box-store door is sprayed in a factory line and cured under heat lamps. Both look identical at year zero. At year five, the difference is obvious.
The 5-year test
Every kitchen looks great in year one. Walk into the kitchen 5 years later. Is the door next to the dishwasher still flat or has it swollen at the bottom edge? Is the corner of the cabinet under the sink still solid or has it puffed? That is the test that separates good cabinets from cheap ones.
The hardware: soft-close vs not, full-extension vs not
This is where the cheap cabinet hides its biggest weakness. The hinge and drawer hardware is the moving part. It gets used 100 times a day.
Cheap cabinets use cheap Euro hinges (the kind that snap shut hard) and 3/4 extension epoxy-coated drawer slides. The hinges loosen over 18 months as the cabinet shifts. The drawers do not pull out fully so you cannot reach the back of the drawer. The drawer slides squeak by year three.
Good cabinets use Blum or Salice soft-close hinges with a 6-way adjustment, and Blum or Grass undermount full-extension soft-close drawer slides. Soft-close means the door stops itself before it slams. Full-extension means you can pull the drawer all the way out and reach everything. Undermount slides are hidden below the drawer box, leaving a clean look and full drawer interior width.
Blum has a lifetime warranty on the hardware. Cheap hardware has 1 year if you can find the manufacturer.
The drawer box: dovetail vs stapled
Pull a drawer out at the showroom and look at the corners. A good drawer has dovetail joints (interlocking finger joints) in solid wood (typically baltic birch or maple). A cheap drawer has stapled or glued butt joints in particleboard or thin plywood.
The dovetail joint cannot fail without breaking the wood. The stapled joint fails when the staples loosen, which happens when the drawer holds anything heavier than spoons. Once the joint loosens, the drawer racks, the slide does not work right, and the door front pops off the front because the screws no longer hold.
Dovetail drawers carry a modest premium per drawer at the cabinet shop. A typical kitchen has 12-18 drawers, so the upgrade across the whole kitchen is small relative to the project. Spending a little more on drawer construction pays back over 25 years like nothing else in the kitchen.
What "good" looks like in a quote
If you are looking at a cabinet quote, here is what good actually means in writing:
- Box: 1/2 or 5/8 plywood, no particleboard, no MDF except for paintable doors
- Doors: solid maple, oak, or walnut, or MDF with catalyzed paint finish for painted styles
- Drawer boxes: 5/8 baltic birch with dovetail joints
- Drawer slides: Blum Tandem or equivalent, undermount, full-extension, soft-close
- Door hinges: Blum Blumotion or equivalent, soft-close, 6-way adjustment
- Finish: catalyzed lacquer or 2K polyurethane, factory-sprayed
- Warranty: minimum 5 years on the box, lifetime on the hardware
If a cabinet quote does not name these specifications, ask. The honest cabinet maker has them on a spec sheet. The cheap one will mumble.
The Orleans kitchen we replaced last year
Family in Orleans built a kitchen in 2019 with builder-grade cabinets. The cabinetry was the bargain line in the reno: box-store brand, MDF box, vinyl-wrapped doors, Euro hinges, 3/4 extension slides.
By 2024 the doors below the sink had warped and would not close. The cabinet bottom under the dishwasher had swelled. The drawer slides on the cutlery drawer were squeaking. The vinyl on three doors was peeling at the edges. They wanted me to "just refinish" the cabinets.
I told them they could not refinish vinyl-wrapped MDF. The vinyl is the finish. Once it peels, you have raw MDF underneath and nothing to spray onto. They needed a full cabinet replacement.
Replacing them with a real plywood-box, dovetail-drawer, Blum-hardware kitchen meant paying for the full cabinetry again, plus related work (countertops re-cut, plumbing reconnections, paint touch-ups). They paid to replace cabinets that were 5 years old.
If they had stepped up to proper cabinets in 2019, they would still have those cabinets in 2034. Instead they paid twice and got far fewer years out of the kitchen.
Cabinets are the bones of the kitchen. You cannot put a premium of countertops, tile, and appliances on a budget set of bones and expect the kitchen to last.
How to know if your existing cabinets are good
If you bought a house with a renovated kitchen and want to know what you have, do these three checks:
- Pull a drawer out and look at the corner. Dovetails (interlocking fingers) are good. Staples are not.
- Open a cabinet door and bend it gently. A solid wood door will not flex. A vinyl-wrapped MDF door will bow under thumb pressure.
- Look at the edge of the bottom shelf inside the cabinet. Striped layers = plywood. Speckled sawdust = particleboard.
If you score 0 out of 3, you have cheap cabinets and they have a clock running. If you score 3 out of 3, you have a kitchen that will outlive the next two trends.
