Custom vs semi-custom vs stock cabinets

These three terms get used loosely, and the differences that matter aren't the ones most showrooms lead with. Here's the practical version.

Stock cabinets

Pre-manufactured in fixed sizes, usually in three-inch increments, and held in a warehouse. You choose from a limited set of door styles and finishes and take what's on the shelf.

• Sizing: fixed. Gaps between your walls and the nearest cabinet size get covered with filler strips.
• Construction: typically particleboard or MDF boxes with a laminate or thermofoil surface. Drawer boxes are often stapled.
• Lead time: days to a few weeks.
• Cost: lowest, by a wide margin.

Stock is the right answer for a rental, a flip, a basement or garage kitchen, or any project where the budget is the binding constraint. It is not a bad choice — it's a different product for a different job, and anyone who tells you otherwise is selling something.

Semi-custom cabinets

Built to order, but from a fixed catalog of sizes. You get real choices in door style, species and finish, and some modification within limits.

• Sizing: still catalog-based, though with more increments and some depth or height modifications available.
• Construction: varies widely. Plywood boxes are common; drawer construction ranges from good to poor. This tier requires the most careful questions.
• Lead time: typically 4–10 weeks.
• Cost: middle.

Semi-custom covers an enormous range of quality. Two kitchens both called semi-custom can be built very differently at nearly the same price, so this is the tier where the six questions at the bottom of this page matter most.

Fully custom cabinets

Designed and built for your specific room. No catalog, no increments, no filler strips.

• Sizing: built to your walls, measured on site. Cabinetry runs wall to wall and to the ceiling if you want it to.
• Construction: at the level of a good shop, solid hardwood doors and face frames, plywood boxes, dovetailed solid-wood drawer boxes.
• Lead time: typically 8–12 weeks after design approval.
• Cost: highest.

When custom is genuinely worth it

Custom earns its price in specific situations rather than universally:

• The room isn't standard. Old houses, sloped ceilings, chimney chases, additions, anything where stock sizing would cost you real usable space.
• You're staying. Ten years or more in the house changes the arithmetic completely.
• You want something specific that the catalogs don't carry — a species, a color match to existing trim, a particular storage solution.
• Ceiling height. Getting cabinetry to a nine- or ten-foot ceiling cleanly is difficult with stock and easy with custom.

When it isn't

We'll say this at the consultation if it applies, because a mismatched job serves nobody:

• You're selling within a couple of years. You won't recover the premium.
• The kitchen is a plain rectangle with standard-height ceilings and you're happy with the layout.
• The budget is genuinely tight and the alternative is cutting the scope in half. A complete good stock kitchen beats a half-finished custom one.

The questions that actually reveal quality

Tier labels are marketing. These six questions are not, and any shop should answer them without hesitating:

1. Are the boxes plywood or particleboard?
2. Are the drawer boxes solid wood and dovetailed, or stapled?
3. Is soft-close hardware standard or an upgrade?
4. Are the doors solid hardwood, or veneer over a substrate?
5. Does the quote include finish, delivery and installation?
6. Who installs — your crew or a subcontractor?

For what it's worth, our answers are: plywood; solid wood and dovetailed; standard; solid hardwood; yes; our own crew.
