Stock cabinets come in preset sizes and are typically sold ready for installation; ready-to-assemble (RTA) cabinets use preset options but arrive knocked down for assembly. Semi-custom cabinets are made to order with selected changes to case sizes, finishes or door styles. These labels do not guarantee a construction grade or quality level. Compare the actual cabinet specification, included accessories, delivery condition, lead time, installation responsibility and written warranty before choosing.
Cabinet labels mostly describe how the order is configured and delivered. They do not replace a line-by-line comparison of construction, fit, finish and installation scope.
The three order types
| Type | Typical ordering format | What to confirm |
|---|---|---|
| Stock | Pre-manufactured in a limited set of sizes and finishes; usually packaged assembled | Available sizes, finish, fillers and what is in stock now |
| Ready-to-assemble (RTA) | Pre-manufactured options packaged knocked down for assembly at the site | Assembly labor, instructions, hardware, delivery damage process and warranty start |
| Semi-custom | Made to order with selected changes to case sizes, finishes or door styles | Exact modification limits, drawings, lead time, change fees and final dimensions |
The National Kitchen & Bath Association’s cabinetry education materials distinguish RTA, stock and semi-custom by these production and delivery differences. Supplier terminology can vary, so ask what the label means on the proposal in front of you.
Compare the specification, not the label
Request a cabinet schedule that names the manufacturer and model for every box. Compare:
- Case dimensions, box material and panel thickness.
- Door and drawer construction, finish and edge details.
- Drawer slides, hinge type, adjustment range and included soft-close hardware.
- Shelves, pull-outs, organizers, toe kicks, finished ends, crown and fillers.
- Delivery condition, assembly responsibility, installation labor and damage claims.
- Warranty coverage, exclusions and who handles service.
The installer should check the wall and floor conditions, appliance openings, plumbing and electrical locations, door swings and clearances before final sign-off. If the room is not square, the plan may need fillers or custom pieces even when most cabinets are stock.
Choose by fit and project control
Stock can suit a layout that works within standard dimensions and available finishes. RTA can suit an owner or installer who has the time and skill to assemble and inspect the boxes. Semi-custom can be useful when selected dimensional or finish changes solve a real layout constraint. Get the final drawing and exact scope in writing before the order becomes non-returnable.
Pair cabinet selections with the quartz and granite countertop comparison, and review the contractor checklist before signing an installation contract. See the porcelain vs ceramic tile comparison if the kitchen plan includes a tiled backsplash. Browse kitchen remodel guides.

Common questions
Are RTA cabinets the same as stock cabinets?
Both use preset size and style options, but RTA cabinets arrive disassembled for on-site assembly. Stock cabinets are generally packaged for installation assembled. Confirm the supplier's exact scope.
Are semi-custom cabinets better quality?
The label describes ordering and customization, not a universal quality grade. Compare the actual box, doors, drawer parts, finish, hardware, warranty and installation requirements.
Do semi-custom cabinets fit any kitchen?
They offer selected changes to sizes, finishes or door styles, but options differ by manufacturer. Measure the room and confirm fillers, end panels, appliance clearances and out-of-square walls with the designer.
What should a cabinet quote include?
List model and dimensions, box and door specifications, finish, hardware, accessories, fillers, panels, delivery, assembly, installation, damage claims, schedule and warranty.
