What changes between the two?
RTA means ready to assemble. The cabinet parts arrive unassembled with the hardware and instructions needed to build each unit. Pre-assembled cabinets arrive as built boxes, though doors, drawers, or trim may still need attention before installation. These are shipping and assembly formats. They don't, by themselves, tell you how well a cabinet is made.
Compare the same line and specifications when possible: box construction, finish, hardware, sizes, and warranty. Confirm who assembles a pre-assembled order and where that work happens. The Kitchen Cabinet Manufacturers Association glossary defines RTA by how the components are supplied, which is a useful starting point for that conversation.
Price the work that follows the purchase
Product and assembly
Compare the cabinet subtotal, any assembly charge, and the labor hours your crew would spend building and checking boxes.
Freight and handling
Get a freight quote for each format. Ask how the order is packed, unloaded, and moved to its staging space.
Space and crew time
RTA needs a clean assembly area and time before installation. Built boxes need room to receive and protect them.
Problems and schedule
Find out how shortages or damage are reported and what a replacement could do to the installation date.
Neither format wins every time. RTA may fit when the crew has assembly capacity and the site offers enough room. Pre-assembly may fit when that crew time is better spent installing or when the schedule leaves little room for another task. Check whether a quoted pre-assembly service includes inspection, door and drawer adjustment, and protection for transport.
A quick comparison worksheet
Use the same cabinet list and delivery address for both columns. Leave an item blank until the provider prices it.
RTA
- Cabinet subtotal: $________
- Freight and delivery: $________
- Assembly hours × loaded labor rate: $________
- Unloading, staging, and handling: $________
- Other quoted charges: $________
- Total: $________
Pre-assembled
- Cabinet subtotal: $________
- Assembly charge, if separate: $________
- Freight and delivery: $________
- Unloading, staging, and handling: $________
- Other quoted charges: $________
- Total: $________
Then mark the first day each option could be ready for installation. A lower total is less useful if the format puts the next trade on hold.
Questions worth asking the provider
- 01
Are the specifications identical?
Ask for the exact cabinet line, construction details, finish, hardware, and warranty for each quote.
- 02
Who assembles and checks each box?
Clarify whether assembly includes squaring the box, checking parts, adjusting doors and drawers, and protecting the finished unit.
- 03
How will the order arrive?
Confirm carton or built-box counts, delivery method, unloading help, and who receives and inspects it.
- 04
What happens if a part is wrong or damaged?
Get the reporting process, documentation needed, and the likely effect on installation before you commit the crew.
