Unassembled Kitchen Cabinets: What They Are & How to Assemble Them

What are unassembled kitchen cabinets? Unassembled kitchen cabinets — also called RTA (ready-to-assemble) cabinets — ship flat-packed with every panel pre-drilled and pre-finished. You put the boxes together yourself with a screwdriver and the included instructions, then install them like any other cabinet. Skipping factory assembly is what keeps the price down: Lily Ann's own RTA lines start at $1,263.51 for a 10-foot run (White Shaker Elite), and every cabinet ships in stock with delivery in 72 hours.

Unassembled = RTA (ready-to-assemble). Same thing, different name — cabinets ship flat-packed instead of pre-built.
Assembly needs one tool: a screwdriver. Holes are pre-drilled at the factory; an instruction booklet ships with every kit.
Lily Ann uses dovetail joinery as standard construction (more durable, no visible metal hardware) and offers metal-clip assembly as a more affordable alternative on the same cabinet.
Skipping pre-assembly is the actual reason RTA costs less — no assembly labor or finished-goods warehousing baked into the price.
All cabinets are in stock, with delivery in 72 hours — no build-to-order wait.
If you'd rather not assemble it yourself, Lily Ann offers a pre-assembled option too — "unassembled" is a choice, not the only way to buy.

If you've been comparing cabinet prices and keep seeing the word "unassembled" next to a much lower number, you're looking at RTA (ready-to-assemble) cabinets. It's the same cabinet as a pre-built one — same materials, same construction — just shipped in flat-packed pieces instead of a finished box, so you (or your installer) put it together on site.

What "Unassembled" Actually Means

An unassembled kitchen cabinet arrives as a set of finished panels — sides, top, bottom, back, face frame or door — rather than a single built box. Every panel is cut, finished, and pre-drilled at the factory before it ships, so nothing about the material or finish quality changes; only the final assembly step moves from the factory floor to your kitchen (or garage).

This is different from unfinished cabinetry, which ships assembled but unpainted/unstained — an unassembled cabinet is already fully finished, just not yet put together.

How RTA Cabinet Assembly Actually Works

Lily Ann's own live product pages describe the process as built around two things: pre-drilled holes and a printed instruction booklet included with every kit. The assembly itself uses one of two joinery methods:

Dovetail assembly — the standard construction on Lily Ann's RTA lines. Interlocking wood joints hold the box together without visible metal hardware, which is more durable and hides the joinery entirely once assembled.
Metal-clip assembly — offered as a more affordable alternative on the same cabinet lines, for buyers who want to save further without giving up the RTA format.

Beyond the joinery, no specialty tools are involved — a screwdriver is the main tool most buyers need, since holes are pre-drilled rather than requiring measuring and drilling from scratch. Lily Ann also publishes step-by-step assembly instructions for every line, plus assembly videos, so the process is documented before you order, not just after.

Why Unassembled Cabinets Cost Less

The price gap between unassembled and pre-assembled cabinetry isn't a quality difference — it's a labor and logistics difference. A pre-assembled cabinet has already had a factory worker build the box, and it ships as a bulkier, heavier finished unit that costs more to warehouse and freight. An unassembled cabinet skips both: it ships flat, taking up a fraction of the space, and the assembly labor shifts to the buyer. Lily Ann's own RTA lines start at $1,263.51 for a 10-foot run (White Shaker Elite, verified against the live product page 2026-08-17) — see the full RTA kitchen cabinets selection for current pricing across all lines.

What to Expect: In Stock, Delivered in 72 Hours

One thing that surprises first-time RTA buyers: unassembled doesn't mean built-to-order. Lily Ann keeps its full RTA catalog — approximately 18 distinct styles — in stock, with delivery in 72 hours from order. There's no factory lead time to wait out; the only extra step compared to a pre-assembled cabinet is the assembly itself once it arrives.

Is an Unassembled Cabinet Right for You?

RTA makes the most sense if you're comfortable spending an evening with a screwdriver per cabinet, or you're working with a contractor who assembles cabinets as a normal part of installation — which is most contractors. It makes less sense if you need the kitchen done same-day with zero extra labor on your end and no assembly step at all; in that case, ask about Lily Ann's pre-assembled option on the same lines rather than assuming RTA is the only way to buy.

Frequently Asked Questions

What are unassembled kitchen cabinets?

Cabinets shipped as pre-cut, pre-finished, pre-drilled flat-pack panels instead of a built box — also called RTA (ready-to-assemble) cabinets. Same materials and construction as a pre-built cabinet; only the final assembly step is different.

Can you buy kitchen cabinets already assembled instead?

Yes. Most RTA sellers, including Lily Ann, also offer a pre-assembled option on the same cabinet lines — unassembled is a way to save money and shipping space, not the only way to buy.

Is it cheaper to buy unassembled cabinets than pre-built ones?

Generally yes. Pre-assembled cabinets cost more to build, warehouse, and ship because they're already bulky finished units. Unassembled cabinets skip that labor and shipping overhead, which is reflected directly in the price.

What tools do I need to assemble unassembled cabinets?

Mainly a screwdriver. Holes are pre-drilled at the factory, and an instruction booklet ships with every kit, so no measuring or drilling from scratch is required.

What's the difference between dovetail and metal-clip assembly?

Dovetail is Lily Ann's standard construction — interlocking wood joints with no visible metal hardware, more durable. Metal-clip assembly is offered as a more affordable alternative on the same cabinet lines for buyers prioritizing price.

How fast do unassembled cabinets ship?

Lily Ann keeps its full RTA catalog — about 18 styles — in stock, with delivery in 72 hours from order. There's no build-to-order factory wait; the only added time versus a pre-assembled cabinet is the assembly step itself.
