RTA cabinets can save you 50–75% on the cabinet line of a remodel. That is a real number and it is worth taking seriously. It is also the right answer for a specific set of kitchens — and the wrong answer for another set, usually the ones in older Tampa-area homes where nothing is square.
Here is an honest comparison from someone who installs both.
In this guide
What RTA actually is
Ready-to-assemble cabinets ship flat-packed and get assembled on site or in a shop. The savings come from three places: no assembly labor at the factory, cheaper freight because boxes ship flat, and standardized sizing that keeps the factory running one process. The cabinets themselves are not necessarily low quality — plenty of RTA lines use plywood boxes and soft-close hardware.
What RTA cannot change is that the sizes are fixed. Cabinets come in 3-inch increments, and anything that does not land on that grid gets covered with a filler strip.
Side by side
| RTA / stock | Custom | |
|---|---|---|
| Installed cost, per linear foot | $100 – $300 | $500 – $1,200+ |
| Sizing | Fixed 3-inch increments; gaps filled | Built to your walls, ceiling and appliances |
| Lead time | Days to a few weeks | Typically several weeks |
| Door and finish choice | A defined catalog | Effectively unlimited |
| Box material | Varies widely — check the spec | Plywood standard |
| Storage design | Standard interiors | Designed around how you cook |
| Assembly labor | Yours, or billed to you | Included |
Where RTA works well
- Rental and flip kitchens, where the goal is a clean, functional kitchen at the lowest defensible cost.
- Laundry rooms, garages and workshops — storage that does not need to be exact.
- Newer homes with square walls, standard 8-foot ceilings and a layout that already lands on the 3-inch grid.
- Straight-run kitchens with no corner conditions and no appliance panels.
- Budgets that are genuinely fixed, where the alternative is postponing the project entirely. A good RTA kitchen beats a deteriorating one.
Where it costs you money
The savings evaporate when the kitchen fights the grid:
- Out-of-square walls. Common in older Tampa-area homes. Stock boxes have to be scribed and shimmed, and the fillers get wider and more obvious the further out of plumb the wall runs.
- Tall ceilings. A 9- or 10-foot ceiling with 30-inch stock uppers leaves a soffit gap you either build around or live with. Custom uppers just go to the ceiling.
- Appliance panels and end panels. Panel-ready refrigerators and dishwashers are where stock lines run out of options fastest.
- Corners and islands. Every corner is a decision, and stock corner solutions waste more space than a designed one.
- Odd-width runs. A 46-inch gap filled with a 42-inch cabinet and a 4-inch filler is four inches of storage you paid for in wall space and did not get.
- Assembly and remediation time. If a professional assembles and squares your RTA boxes, that labor comes off the savings.
The honest test: add up the fillers. If your layout needs more than a few inches of filler across the kitchen, the design is being bent to fit the cabinets rather than the other way round — and you are paying for wall space you cannot use.
The semi-custom middle
Semi-custom runs roughly $200–$500 per linear foot installed and covers most of what people actually want from custom: modified depths and heights, a wider door and finish catalog, real storage accessories. If your layout is close to standard but you want the finish and the interior fittings to be yours, this is often the best value in the whole market.
A decision framework
Four questions, in order:
- How long will you own the house? Under five years, RTA or semi-custom is defensible. Longer, and the daily annoyances of a compromised layout compound.
- Is the layout changing? If walls, plumbing or appliances are moving, you are already paying for a design — get cabinets that fit the design instead of designing around the cabinets.
- How square is the room? Have someone measure diagonals and check the walls for plumb before you order anything. This one question decides more than the others combined.
- What is the box made of? Regardless of tier, plywood over particleboard in this climate. See our Tampa cabinet cost guide for why.

Frequently asked questions
How much cheaper are RTA cabinets than custom?
RTA and stock cabinets typically run $100 to $300 per linear foot installed against $500 to $1,200 or more for custom, so the saving on the cabinet line is roughly 50 to 75 percent. Assembly labour and remediation for an out-of-square room eat into that.
When are RTA cabinets a bad idea?
When the room fights the 3-inch size grid: out-of-square walls, tall ceilings, panel-ready appliances, complex corners, or runs that leave wide filler strips. A good test is to add up the fillers in the plan. More than a few inches across the kitchen means you are paying for wall space you cannot use.
What is semi-custom cabinetry?
Stock sizing with modifications: adjusted depths and heights, a wider door and finish catalog, and real storage accessories. It runs roughly $200 to $500 per linear foot installed and covers most of what people actually want from custom.
How do I know if my kitchen walls are square?
Have someone measure the diagonals of the room and check the walls for plumb before ordering anything. In older Tampa-area homes walls are frequently out, and that single measurement decides more about the RTA-versus-custom question than budget does.
