It always starts the same way.
Someone walks into a big-box home improvement store, finds a cabinet they like, and takes a photo. Then they get a quote from a custom cabinet maker, and the number is three times higher. So they go back to the photo and ask themselves, “Is it really that different?”
The honest answer is it depends on what wall you’re putting it on.
In a new construction apartment with square walls and standard dimensions, maybe not. In a pre-war Brooklyn brownstone with a wall that bows in the middle and a ceiling that’s 9 feet 4 inches on one side and 9 feet 1 inch on the other, absolutely.

Stock cabinets are pre-built in fixed sizes, sitting in a warehouse waiting to ship. Walk into any home improvement store, and you’re looking at stock cabinets.
They come in standard widths, typically 24, 30, 36, or 48 inches, and standard heights. They’re painted or finished before you buy them. What’s on the shelf is what you get.
Where stock cabinets genuinely work:
What they don’t do well: fit non-standard spaces. And in New York, almost no space is standard. A stock 36-inch cabinet in a 39-inch wall leaves you with a 3-inch gap that needs a filler panel, which always looks exactly like what it is.
