RTA (ready-to-assemble) means the cabinet ships as flat panels with fittings and instructions, and is assembled on site. The carcass joints are cam-and-dowel or confirmat so the box can be built with hand tools, and every part carries a code that matches the drawing and the packing list.
What arrives on site
A flat-packed cabinet is not a kit of loose parts. Panels are numbered and matched to a part list, fittings come bagged by cabinet rather than by type, and the carton carries the unit reference, room and elevation. Good packing is what makes RTA work — a mixed bag of cams and dowels across forty cabinets costs more in labour than the freight saved.
The joints are the other half. Cam-and-dowel locates and locks; confirmat screws drive straight into the panel edge. Both allow assembly with a drill and a screwdriver, and both can be taken apart — which matters for later alteration, and is the main technical difference from a glued factory carcass.
| Property | RTA | Pre-assembled |
|---|---|---|
| Shipping volume | Lowest | 30–60% higher |
| Site labour | Assembly required | Unpack and place |
| Joint type | Cam-and-dowel or confirmat | Glued dowel, sometimes cam |
| Damage risk | Edge damage in transit | Corner and face damage |
| Later alteration | Can be dismantled | Fixed |
| Best for | High labour-cost balance, remote sites | Tight programmes, finished quality |
When RTA is the right call
When freight and storage dominate the cost. A 40 ft container holds roughly 40–60% more cabinetry flat-packed than assembled, so on a long sea route the saving is substantial — often the difference between a project landing inside budget or not.
It also suits sites where assembly labour is cheap and available, and projects where the units have to be carried up stairs or through narrow openings. A flat panel goes where a 2.1 m assembled carcass cannot.
When RTA is the wrong call
When the programme is tight. Assembly is real labour — a two-person team will build perhaps 25–40 carcasses a day, and every one has to be squared, checked and cleaned before the doors go on. On a handover-driven fit-out, that is time the programme does not have.
And when quality inspection matters more than freight. A factory-glued carcass is square and rigid before it leaves; an RTA box is only as square as the person who assembled it. If the installer is not your team, the standard is not yours either.
Frequently asked questions
Is RTA the same as flat-pack?
Yes, in cabinet usage the terms are interchangeable. Flat-pack is the shipping form; RTA is the assembly state.
How much space does RTA save in a container?
Roughly 40–60% more cabinetry per container than pre-assembled, depending on unit sizes and packing efficiency.
Can RTA cabinets be dismantled and re-used?
Yes, if the joints are cam-and-dowel or confirmat. A glued carcass cannot be taken apart without damage.
Is RTA lower quality?
Not inherently. The board, hardware and finish can be identical. What differs is who assembles the box and how square it ends up.
