Stand in a finished kitchen and look at the narrow strips of material between the cabinets and the walls. Filler strips. In a stock kitchen there might be four of them, one nearly 100 mm wide beside the fridge, because the boxes come in 75 mm increments and the room does not.
Nobody notices fillers in a showroom. Everybody notices them at home, at eye level, for a decade. They’re also the cleanest illustration of what separates the three cabinetry tiers, so they’re a good place to start a conversation most homeowners begin in the wrong order — with door styles instead of dimensions.
What the Three Tiers Actually Mean
Stock cabinetry is manufactured to fixed widths and depths and warehoused. You choose from a catalogue, it ships fast, and your room is fitted to the boxes.
Semi-custom starts from the same standard boxes but allows modifications: a reduced depth here, a different door, a non-standard finish, occasionally a width change for a fee. It’s the middle of the market and, for a lot of rectangular condo kitchens, an entirely sensible answer.
Custom means the boxes are built to your dimensions after someone measures the actual room. No forced increments, no filler gymnastics, no “we’ll make it work.” It also means a longer lead time and a shop that has to be genuinely good, because there’s no catalogue to hide behind.
The Box Matters More Than the Door
Door style is what sells cabinetry. Construction is what you live with.
Ask about carcass material and thickness. Plywood versus particleboard matters most in wet zones — the sink base and the dishwasher run — where a swelled panel is a full-cabinet replacement. Ask about drawer boxes specifically: solid wood or metal sides with full-extension undermount runners will outlast side-mount epoxy slides by years, and you’ll feel the difference daily.
Ask about the hinge. A quality six-way adjustable hinge lets an installer bring an entire run into alignment and keeps it there. Cheap hinges drift, and drifting hinges are why some kitchens look tired at year five with perfectly good doors.
Then ask about the finish. A factory-sprayed and cured finish behaves differently from a site-brushed one, particularly on painted cabinetry, and the gap widens with every winter of low indoor humidity.
Storage Is a Measuring Problem, Not a Gadget Problem
The kitchen storage industry would like to sell you accessories. Most of them solve problems created by bad planning.
Better storage starts with an inventory. How many dinner plates do you own, and what do they measure? Is the stand mixer used weekly or twice a year — because one of those belongs on the counter and the other belongs on a shelf you need a stool to reach. Do you buy paper towel in bulk from a warehouse store, and if so, does anything in the drawn design accommodate a pack that size?
A few principles hold almost universally. Drawers beat low cupboards for anything below waist height, because you stop kneeling on a tile floor to find a pot. Heavy things belong between knee and shoulder. The cutlery drawer belongs beside the dishwasher, on the side the door swings clear of. And the first 600 mm beside the range should be landing space, not storage — it’s where the hot pan goes.
Workflow Beats Layout Names
Galley, L-shaped, U-shaped, open concept: these are descriptions, not designs. What matters is the sequence you repeat a thousand times a year.
Groceries come in, and something has to hold them while the fridge door is open. Prep happens between the sink and the range, and it needs uninterrupted counter — a cooktop that eats the middle of the only long run creates two useless offcuts of counter instead of one workspace. Waste and recycling belong in the prep zone, not across the room, because that walk is what determines whether the household actually sorts.
Then there’s the second cook. Most kitchens are designed for one person and used by two, plus whoever is standing at the island doing homework. Clearance between opposing runs is the single most consequential number in the whole plan, and it is routinely traded away to gain a few centimetres of counter that nobody misses.
Where the Custom Premium Pays for Itself
Custom earns its money in awkward rooms: Toronto semis with chimney breasts, condo kitchens with structural columns, ceiling heights that beg for cabinetry running to the crown instead of a dust shelf above it, and any house where walls are out of plumb enough that scribed end panels are the only clean answer.
It earns it again when you have specific storage requirements — a deep drawer sized to your actual pot set, a 140 mm pull-out beside the range, appliance garages sized to appliances you own. And it earns it on integration, where panelled fridges and dishwashers need the surrounding millwork built to the appliance’s real dimensions rather than to a catalogue’s assumption.
Where custom doesn’t pay: a rectangular condo kitchen with standard appliances, standard ceiling height and square walls. Pay for the better carcass and hardware there, not for bespoke dimensions you don’t need.
The Question to Ask Before You Sign
Ask how cabinetry appears in the quote. A single scope of work priced against measured drawings is a very different commitment from a cabinet order plus an installation allowance to be reconciled later — and the Canadian Home Builders’ Association has long argued that detailed written specifications are the baseline of professional work for exactly this reason. Firms that manufacture their own boxes typically quote kitchen renovations with custom cabinetry as one line of responsibility, which at minimum makes comparison between bids honest.
The cabinetry is usually the largest single line in a kitchen budget. It deserves more scrutiny than the backsplash gets, and it almost never receives it.
