RTA Cabinets Cost for a Full Kitchen, and Are They Worth It?

How much do RTA cabinets cost for a whole kitchen? On our retail pricing, cabinets for a standard 10×10 kitchen in a value ready-to-assemble line land around $3,000–$5,000, and US Cabinet Depot's Shaker line typically runs $2,500–$4,500 for that footprint. That's the box price, though, and it isn't what you'll spend. Assembly time, fillers, crown, hardware, freight and installation sit between that number and a finished kitchen. Depending on who does the work, they can add as much again.

Six of the lines we sell can ship flat-pack: J&K (RTA only), plus US Cabinet Depot, KCD, Tribeca, Mantra and Modernform (each RTA or factory-assembled). So we build these budgets every week. Below are two of them worked all the way through, a 10×10 and a larger kitchen with an island, with every line item that tends to be missing from the first number people see. Then comes the honest answer to whether flat-pack is worth it for you, because sometimes it isn't.

Key takeaways

• On our cost estimator, value RTA lines (KCD, US Cabinet Depot, Tribeca) run roughly $150–$250 per linear foot at retail, cabinets only. That's about $3,000–$5,000 for a 10×10.
• If you assemble and pay a pro to install, a 10×10 on value RTA lands around $4,650–$9,250 for cabinets, a crown allowance and installation, before countertops. Freight and decorative hardware are quoted on top.
• A larger kitchen (about 30 feet of cabinets plus an island, a pantry and crown) runs roughly $6,100–$10,100 in value-tier boxes alone.
• Assembling it yourself is where the savings are. Paying an installer $50–$100 a box to assemble can erase the gap between flat-pack and factory-assembled.
• RTA is worth it when you have the hours, the floor space and a square-minded helper. It isn't worth it on a tight schedule, on frameless boxes you're not confident squaring, or when labor is billed by the box.

The Numbers We Actually Quote From

Most online answers to this question give you one range and no source. Here's ours, and where each figure comes from, so you can check the arithmetic in the budgets below.

Two caveats before the math. First, the per-foot bands are for boxes, doors, drawers and the hinges and glides that come with them. They are not countertops, appliances or labor. Second, a linear-foot figure is an average. A layout heavy in drawer bases and tall cabinets prices toward the top of a band, and one with plain door bases prices toward the bottom. The only exact number is an itemized quote on your plan.

A 10×10 Kitchen, Worked Line by Line

The "10×10" is the industry's benchmark: an L-shaped kitchen with two 10-foot walls, usually 10–12 cabinets including a 36" sink base, typically a corner unit and matching wall cabinets. Call it about 20 linear feet of cabinetry. Here it is in a value flat-pack line, first with you doing the labor, then with you paying for it.

Read the right-hand column carefully. Once you pay someone to do both jobs, the labor can cost as much as the cabinets. And on the assembly line specifically, $600–$1,500 is the same size as the $500–$1,500 that choosing flat-pack saves over factory-assembled on a 10×10. Paying for assembly and then paying separately for installation is the one combination where flat-pack rarely makes sense. If you won't assemble, price the same line factory-assembled; US Cabinet Depot, KCD and Modernform all ship that way.

The middle scenario is the one most homeowners actually pick: assemble the boxes yourself on a Saturday, then pay an installer to hang them. That lands around $4,650–$9,250 for cabinets, crown allowance and installation before freight, pulls and countertops. For comparison, Fabuwood ships only pre-assembled, and our Fabuwood pricing puts a 10×10 in its framed Allure series at typically $4,000–$7,000, cabinets only. That's the right benchmark when you're deciding whether the flat-pack saving is worth your Saturday.

Moving up to J&K or Modernform puts the cabinet line at roughly $5,000–$8,000 retail on the same footprint (20 feet × $250–$400), with Modernform's flat-pack orders below that. The labor lines don't change. What you're paying more for is the door and box spec, not the format.

A Larger Kitchen: 30 Feet, an Island and a Pantry

Most real kitchens aren't a 10×10. Here's the kind we quote more often: about 30 linear feet of perimeter cabinets in an L or U, an island, a floor-to-ceiling pantry and crown. We'll assume around 30 boxes counting the island and the pantry. Your count will differ, and the math scales with it.

Using the estimator's own method, the add-ons stack as percentages on the base: 20% for the island, 10% for tall cabinets and 5% for crown, so the base is multiplied by 1.35.

Put together with you assembling and a pro installing, a value-tier kitchen this size runs roughly $9,100–$19,100 before demolition, freight, pulls and countertops. If the installer assembles too, it's roughly $10,600–$22,100. The installation range is wide because regional labor rates, crown work, scribing to old walls and island electrical all push it around. Get your installer's number before you decide the format, not after.

Two things change once a kitchen gets this big. The assembly job stops being a Saturday and becomes a project; 30 boxes is a lot of cam locks. And the tall pantry is a two-person box whichever way it arrives. Some buyers split the difference and assemble the simple base and wall boxes themselves, but have the pantry, the oven cabinet and anything frameless done by someone who assembles cabinets every week. Whether a line will ship one order partly assembled is a quote question. Ask rather than assume.

The Line Items People Forget

When a flat-pack kitchen goes over budget, it's almost never the cabinets. It's one of these.

1. Assembly hours. Covered in detail below. The short version: it's real time. Your time is free only if you'd otherwise be doing nothing.

2. Fillers and scribe. Cabinets come in 3" width steps and rooms don't. Where a run meets a wall, an appliance or a corner, a filler strip closes the gap, and scribe molding covers the wavy line where a cabinet meets an out-of-plumb wall. Both are separate line items, and fillers usually arrive oversize to be ripped down to width on site, which means a saw and a careful cut. Where each piece goes is laid out in our fillers, scribe and end-panel explainer.

3. Crown and light rail. Crown is sold by the stick, and every outside corner is a compound miter. The estimator's +5% covers the material. It doesn't cover the carpentry, which is one of the things that pushes installation toward the top of its range. Light rail under the wall cabinets is the same story on a smaller scale.

4. End panels and toe kick. The exposed side of a run, both ends of an island and the back of an island all need a finished panel or skin, because the box side isn't a show surface. Toe kick is often shipped as a length to cut. An island with a seating overhang can need more panel than people expect. This is the item most often missing from a "10×10 price."

5. Knobs and pulls. Hinges and drawer glides come with the cabinets on the lines we sell. Decorative hardware isn't part of the per-foot bands above; confirm on your quote whether any is included. Count before you shop: one per door, one or two per drawer depending on width. A 30-foot kitchen with stacked drawer bases can need a surprising number, and a mid-priced pull multiplied by that count is a real line.

6. Freight and the last fifty feet. Freight is calculated from the order's size, weight and destination and itemized in your quote, and flat-pack ships denser than assembled boxes. Standard service is curbside: the driver brings pallets to the curb or the end of the driveway, and moving them inside is on you. Lift-gate service and inside delivery aren't part of standard curbside service; if you need either, ask for it to be priced on your quote. Our shipping FAQ covers the delivery appointment and the claim windows. Visible damage must be noted within 5 days of delivery; concealed damage within 5 days of discovery and no later than 30 days after delivery. With 30 flat boxes that means opening and checking every carton promptly, even if assembly is weeks away.

7. Storage. Thirty flat cartons need a dry, climate-controlled place to wait. An unheated winter garage or a hot summer one isn't suitable, and damage from improper storage isn't covered under warranty. If the only space you have is the garage, schedule delivery close to assembly.

8. Tools and consumables. A drill-driver, a square, clamps, a good level, shims and cabinet screws for installation. The instructions for your line will say whether glue goes in the joints. Most people own half of this list; the other half is a hardware-store run.

9. Demolition, disposal and the empty kitchen. Tearing out the old cabinets is $300–$800 if your installer does it. Then there's the cost that never appears on a quote: the days without a kitchen. Flat-pack adds assembly days to that stretch unless you assemble before demo.

Assembly Hours, Counted Honestly

Flat-pack cabinets from the lines we sell are machined panels joined with cam locks and hardware packs, with doors and drawer fronts that go on after the box is built. Expect the first box to take 30–45 minutes while you work out how the hardware goes together, and 15–20 minutes each after that. For a 10×10's 12–15 boxes, that's roughly 3–5½ focused hours. For the 30-box kitchen above it's closer to two days.

The time estimate is the easy part. What actually decides whether flat-pack works out:

• Square matters more than speed. A box assembled a few degrees out of square will hang, but its doors won't line up with the next box. Check each box corner to corner with a tape before you move on; the two diagonals should match.
• Frameless is less forgiving. With no face frame to hide small errors, a frameless box's squareness shows directly in the door gaps. On Modernform's European series and US Cabinet Depot's frameless Palermo and Torino, our advice is to pay for assembly unless you've done this before.
• Space. You need a clear, flat floor large enough to lay out a tall-cabinet side panel, plus somewhere to stack finished boxes that isn't the room being installed.
• Drawers and doors last. Build the boxes, hang them, then fit and adjust doors and drawer fronts. Hanging doors on boxes that aren't installed yet only means adjusting them twice.

What is your time worth here? One honest way to decide: the 3–5½ hours on a 10×10 are worth $600–$1,500 at the paid-assembly rate. If that sum matters to your budget and you're comfortable with a drill, it's among the easiest money in a kitchen remodel. If you'd rather spend the Saturday elsewhere, factory assembly on the same line is the cleaner way to pay for it than a per-box installer fee. Our pre-assembled buying guide covers that path.

The Flat-Pack Lines We Sell, and Where Each Fits

Four of our flat-pack lines are compared below; Tribeca and Mantra follow the table. They're built differently, and the differences matter more than the per-foot price.

US Cabinet Depot is the one we reach for when the budget is tight and the spec can't be: plywood framed boxes, dovetail drawers and a published limited lifetime warranty, flat-pack or assembled on the same order. It ships from eight warehouses. Stocked items leave within 1–3 business days, and freight takes another 7–14 business days. The full review goes series by series.

KCD matters because of its two tiers. Premier is plywood; the Essential builder tier uses particleboard sides. On a flat-pack order, that's a real difference in how well cam-lock joints hold over time, and it belongs on your quote in writing. The KCD review and our KCD cost guide cover it; KCD has no public price list.

J&K only ships RTA, which is the trade-off for its solid-wood door spec at its price. Delivery is 2–4 weeks. If you don't want to assemble at all, J&K is the wrong line, not a line to pay someone to assemble. The J&K review and the J&K vs US Cabinet Depot comparison set it against its closest rival.

Modernform gives you the choice. Its Shaker lines are forgiving to assemble; its frameless European series is where we recommend paying for assembly. The Modernform review has the details.

Two more lines can also ship either way. Tribeca sits in the value tier on our estimator and Mantra in the most-popular tier; confirm flat-pack availability for your specific door at quote. Our RTA kitchen cabinets page lists what we stock in flat-pack form.

Are RTA Cabinets Worth It? When Yes, When No

Flat-pack isn't a quality tier. It's a shipping format. The same US Cabinet Depot, KCD or Modernform cabinet can arrive flat or built, with identical construction either way. So the question isn't whether flat-pack cabinets are good. It's whether the format saves you money once your own situation is counted.

It's worth it when:

• You'll do the assembly yourself, or someone in the household will, and you have a dry room to do it in.
• The kitchen is a flip, a rental turn or an ADU, where every few hundred dollars counts and the style is a standard framed shaker. Our contractor guide covers that playbook.
• Access is tight: a narrow stair, a third-floor walk-up, a basement. Flat cartons go where built boxes won't.
• You want the specific door or finish a flat-pack line offers, such as J&K's solid-wood glazed Traditional doors, and you're fine with the format that comes with it.
• You're a trade buyer. Through Captivating Pro, trade accounts price 20–40% below retail, and your crew can assemble between other tasks.

It isn't worth it when:

• You'll pay an installer by the box to assemble. At $50–$100 per box, the saving over factory-assembled mostly disappears, and you've added a step.
• The kitchen is frameless and nobody on the job has squared frameless boxes before.
• The schedule is tight. Assembly adds days, and every day is a day without a kitchen.
• You have nowhere dry to store 15–30 cartons, or nowhere flat to build them.
• You're choosing between a flat-pack line and an assembled one purely on price. A Fabuwood Allure 10×10, typically $4,000–$7,000 on our pricing, arrives built with Blum hardware. Compare your all-in flat-pack number against that, not your box-only number. Our Fabuwood vs J&K comparison is exactly this decision.

For the broader choice between formats and tiers, see RTA vs pre-assembled for the format question and the kitchen layouts guide for how your plan's shape drives the cabinet count, which drives every number on this page.

How to Keep the Savings You Paid For

1. Get the quote both ways. Have the same layout priced flat-pack and assembled in the same line, so the saving is a dollar figure rather than a percentage.
2. Get the installer's number before you order. Ask for it with and without assembly. That single quote decides the format.
3. Put every accessory on the first quote. Fillers, scribe, crown, light rail, end panels, toe kick. The kitchens that go over budget are the ones where these were "added later."
4. Inspect every carton on delivery day. Note visible damage on the delivery receipt. Open everything within the claim window even if you're not assembling yet. A missing panel found in week three stops the job.
5. Assemble before demolition. Build the boxes while the old kitchen still works, so the kitchen-less days cover only installation.
6. Buy plywood where water lives. If you're choosing between tiers of one brand, put the plywood box on the sink base at minimum.
7. Trade? Use the trade account. The 20–40% trade discount is bigger than the RTA saving itself on most kitchens.

Frequently Asked Questions

What does flat-pack cabinetry cost per linear foot?

On our retail pricing, the value flat-pack tier (KCD, US Cabinet Depot, Tribeca) runs about $150–$250 per linear foot, and the next tier up (J&K, Modernform) about $250–$400, cabinets only. Labor, countertops and appliances are separate.

What does a 10×10 kitchen cost in flat-pack?

About $3,000–$5,000 in value-tier cabinets on our estimator, with US Cabinet Depot's Shaker typically $2,500–$4,500. Add $1,500–$4,000 if you hire out installation, and $600–$1,500 more if you also hire out assembly.

How much does flat-pack save compared with assembled?

In the same line, the assembled version usually runs 15–25% higher, close to $50–$100 a box, with freight a little higher as well. On a 10×10 the gap is roughly $500–$1,500, and you only keep it if you do the assembly yourself.

How long does it take to assemble a kitchen of flat-pack cabinets?

Plan on 30–45 minutes for the first box and 15–20 minutes for each one after. A 10×10 of 12–15 boxes is about 3–5½ hours; a kitchen of about 30 boxes is closer to two days.

Are ready-to-assemble cabinets lower quality than assembled ones?

Not inherently. The lines we sell build the same cabinet either way, and the format only changes who does the assembly. Quality comes from the box material, the drawers and the hardware. Check those, for example plywood vs particleboard sides on KCD's two tiers, rather than the shipping format.

Does shipping cost more for a flat-pack kitchen?

Usually less than the same order assembled, because flat cartons ship denser. Freight is calculated from size, weight and destination and itemized on your quote. Standard service is curbside, and lift-gate or inside delivery is quoted separately.

Can I buy J&K cabinets assembled?

No. J&K ships RTA only. If you want an assembled cabinet with a similar all-wood spec, price US Cabinet Depot or Modernform assembled, or Fabuwood, which ships pre-assembled only.

Is flat-pack a good call for a rental or a flip?

Often yes. A standard framed shaker in a value line, assembled by the crew, is the cheapest sound kitchen we sell. Put a plywood box on the sink base and keep the layout simple.

Get Your Kitchen Priced Both Ways

Every number above is a range because your layout isn't a 10×10 in a catalog. Send your measurements through our free 3D design service and ask for the same kitchen quoted flat-pack and assembled, with fillers, crown, panels and freight itemized. A designer replies within one business day, and the full design and quote follow within 24–48 hours. To judge a door first, order US Cabinet Depot, J&K, KCD or Modernform door samples.
