Custom Cabinets vs Off-the-Shelf: Why Flat-Pack Falls Short
The real cost of flat-pack convenience — and what you get when you choose bespoke
7 min read · Cupboards2Cabinets design team
Off-the-shelf kitchen units are genuinely good value for a simple rectangular room. The problem is that very few South African kitchens are simple rectangular rooms.
01The filler-panel problem
Modular units come in fixed widths. Any leftover space becomes a filler panel — dead storage you paid for in floor area but cannot use. In a typical 4m run, fillers commonly waste 200–400mm.
02Specification differences
Flat-pack carcasses are usually 16mm board with thin edge tape and side-mounted runners. Custom cabinetry is typically 18mm moisture-resistant board with 2mm ABS edging and undermount soft-close runners. Both look similar on day one and very different in year seven.
- Board: 16mm standard vs 18mm moisture-resistant
- Edging: 0.45mm tape vs 2mm ABS
- Runners: side-mount vs undermount full-extension
- Fit: fixed widths vs scribed to your walls
03When off-the-shelf is the right answer
Rental properties, garages, temporary layouts and simple laundries. If the room is square, the budget is fixed and the stay is short, modular is sensible — just specify better hardware if the range allows it.
The takeaway
Modular wins on price per unit; bespoke wins on usable storage per square metre. Compare those two numbers, not the headline totals.
