If you’ve been shopping for kitchen cabinets, you’ve probably come across RTA — Ready to Assemble. You may have also gotten a quote for fully custom installed cabinets and felt the sticker shock. So what’s the actual difference, and which one is worth the money?
The honest answer is “it depends on your kitchen.” Here’s how to figure out which side of the line you’re on.
What RTA cabinets actually are
RTA cabinets ship flat-packed in boxes, like high-end IKEA furniture. The panels, hardware, and assembly instructions arrive at your door. You (or someone you hire) put them together with included cam locks, dowels, and sometimes glue, then install them in your kitchen.
The selling point is cost. By cutting out warehouse storage and pre-assembly labor, RTA suppliers can deliver finished-looking cabinets at 40–60% the price of comparable pre-assembled stock cabinets — and a much smaller fraction of custom.
Sizes are standard: 12″, 15″, 18″, 21″, 24″, 30″, 36″ and so on, in fixed increments. Door styles, colors, and species are pre-selected from a catalog. You pick from what’s offered.
What fully custom installed cabinets include
Custom cabinets are built to your specific kitchen dimensions, in any size to the eighth of an inch. The doors, drawer fronts, finishes, interior accessories, hardware, and box construction are all chosen for your project. A cabinet shop measures your space, designs around your appliances and walls, builds the boxes in their shop, sprays the finish in a controlled environment, and installs everything on site.
What you’re paying for beyond the cabinets themselves:
- Custom sizing — no filler strips, no compromises
- Better materials (real plywood boxes, dovetail drawer construction, solid wood doors)
- Premium hardware (Blum or Salice hinges, full-extension soft-close drawer slides)
- In-shop finishing with conversion varnish or catalyzed lacquer — not the off-the-shelf finishes used on most RTA
- Design consultation, measurement, and installation labor
- A warranty from someone you can drive to
The real cost difference
For a mid-size Tampa kitchen (20–30 linear feet), the numbers usually shake out like this:
- RTA boxes only: $4,000–$9,000
- RTA assembled and installed by a contractor: $10,000–$16,000
- Mid-range stock cabinets (pre-assembled, installed): $14,000–$22,000
- Fully custom installed cabinets: $20,000–$40,000
So the all-in cost gap between RTA and custom is usually 2–3x. If you’re shopping based on the box-only price, the gap looks bigger than it actually is. By the time RTA is in your kitchen and working, you’ve added assembly, installation, fillers, and trim labor.
When RTA makes sense
RTA is the right choice when:
- Your kitchen layout is rectangular with standard dimensions that match the RTA sizes available
- You’re flipping a property or doing a rental and need to hit a budget
- You’re handy and want to assemble them yourself
- You’re open to the door styles and finishes the supplier offers
- You don’t plan to be in the home for 15+ years
For these situations, RTA delivers real value. The quality of the better RTA brands (CliqStudios, Kitchen Cabinet Kings, the higher-tier lines from Cabinets To Go) is genuinely good — plywood boxes, dovetail drawers, soft-close hardware. Not the same as a custom shop’s work, but legitimately serviceable cabinetry.
When RTA doesn’t make sense
RTA breaks down in a few situations:
- Old houses with out-of-square walls. Stock sizes plus standard fillers can’t hide a wall that’s 5/8″ out from one end to the other. Custom can.
- Unusual ceiling heights. If you have 10-foot ceilings and want stacked uppers, or 7-foot ceilings that need shorter cabinets, RTA can’t accommodate.
- Specific design vision. If you want a particular wood, a non-catalog color, an inset door, beaded inset, integrated appliance panels, or any custom detail — RTA can’t deliver.
- Awkward layouts. Tight corners, weird angles, columns to work around, original cabinetry that doesn’t line up with anything — this is where custom earns its premium.
- Long-term ownership. If this is your house for the next 20 years, the durability and refinishability of a custom job pays back over time.
What to look for in RTA quality
RTA quality varies enormously. Some lines are excellent. Some are particleboard with stapled drawers and won’t survive five years. The spec sheet is everything. Look for:
- Plywood boxes, not particleboard. 1/2″ minimum, 3/4″ preferred. Particleboard swells.
- Solid wood doors and drawer fronts. Not veneered MDF, not thermofoil — solid hardwood or solid MDF if painted.
- Dovetail drawer construction. Stapled or doweled drawer boxes loosen up.
- Soft-close hinges and full-extension drawer slides. Blum and Salice are the brand names to look for.
- Real finish, not stain-and-poly DIY. Conversion varnish or catalyzed lacquer is ideal but rare in RTA — at minimum, a sprayed (not wiped) finish.
If a brand won’t tell you what’s in their boxes, that answer is its own answer.
Can you mix RTA and custom?
Yes, and it’s a smart move in some kitchens. The most common approach is RTA for the perimeter base cabinets (where standard sizes work fine) and a custom island, custom range hood surround, or custom built-in pantry where the design matters most visually.
Two things to know if you mix: the finishes won’t match perfectly unless you have the custom pieces sprayed to match the RTA paint code (and even then, the substrates absorb finish differently), and you’ll want to plan the design so the eye doesn’t bounce between the two. Most often this means painted RTA with a contrasting custom piece — a walnut island against painted white perimeter cabinets, for example.
The honest recommendation
If you’re budget-constrained and your kitchen is standard, go with quality RTA from a reputable supplier and have a real installer put them in. You’ll get a kitchen you’re happy with for less.
If your kitchen is unusual, you care about how it looks and lasts, or you’re going to be in the house for the long haul — custom earns the gap. The materials are better, the fit is exact, and you’re working with people you can call if something needs attention five years later.
