Cabinet Buying Guide 10 min read · Updated September 2026

One question we hear at the counter more than almost any other: “What am I actually buying when a cabinet is sold as RTA?”

Here is the short version. RTA stands for ready to assemble.

The cabinet ships flat-packed in a box, panels pre-drilled and cut, all the hardware included, ready to put together on site with hand tools.

Before BluePrint existed, I ordered a full kitchen of these cabinets, assembled every box, and installed them in my own Fredericton home. So this guide comes from someone who has actually assembled the product before selling it.

Here is what RTA cabinets are, what they are made from, what they cost, and who they suit. No hedging.

TL;DR

RTA cabinets ship flat-packed, and you build them on site with hand tools, which is how they skip factory labor and come in cheaper.

  • ●The letters describe how the cabinet is delivered. An RTA box can be built from cheap particleboard or from good plywood, and the material decides whether it lasts.
  • ●BluePrint’s RTA boxes use 5/8″ plywood with 3/4″ solid birch face frames, joined by a sliding dovetail and metal brackets rather than cam locks.
  • ●Most full kitchen packages land between $5,000 and $25,000 CAD plus HST, roughly $350 to $700 per linear foot.
  • ●A base cabinet goes together in about 10 to 15 minutes once the hardware is sorted.

What “RTA” Actually Means

RTA is the cabinet industry’s term for ready-to-assemble. Flat pack is the furniture-retail name for the same idea.

Either way, the cabinet arrives as a bundle of finished, pre-drilled panels rather than a built box, and you connect them where they are going to live.

The Kitchen Cabinet Manufacturers Association, an American trade body, defines an RTA cabinet as one shipped with all the parts, fasteners, and instructions needed to build a single cabinet without power tools.

A cordless drill speeds the work, but the definition really is that simple.

A typical box arrives with everything needed to build one cabinet:

  • ●the two side panels and a full back panel
  • ●the shelves
  • ●the face frame and the door or doors
  • ●the drawer parts, the hinges, and the slides
  • ●a bag of screws, plus color-matched putty for the nail holes

Nothing gets cut on site.

How RTA Cabinets Differ From Custom, Stock, and Pre-Assembled

Cabinets get sold four main ways.

  • ●Custom cabinets are built to order in a shop for your exact room.
  • ●Semi-custom and stock cabinets come in set sizes and, in most cases, arrive built.
  • ●Pre-assembled cabinets are the same standard sizes as RTA, put together at the factory before they ship.
  • ●RTA is that last group, delivered flat so you do the building.

The gap that matters for most buyers is cost and shipping. A built cabinet is mostly air, so it costs a lot to freight, and it is easy to damage in transit.

A flat box ships tighter, cheaper, and with less to go wrong on the truck. You can read more on whether they arrive pre-assembled and what actually shows up at your door.

One word worth pinning down is custom. Genuine one-off cabinetry exists, is beautiful, and costs a different order of magnitude.

Most local shops selling “custom” kitchens work from standard sizes too. RTA lines like ours run in three-inch width increments, which covers the great majority of real kitchens.

The only thing a standard box cannot do is a true one-off, like fitting two drawers where the layout wants three.

What RTA Cabinets Are Made From

Here is where the letters RTA tell you nothing. Two boxes can both be ready to assemble and be built from completely different materials.

The material, and the way the box is joined, is what separates a cabinet that lasts from one that fails quietly in year five.

The Cabinet Box

The box is the part you never see, and the part that carries the load.

Cheap RTA uses particleboard: wood chips bonded with resin. Particleboard does not handle moisture well, and it loses its grip on screws over time, which is why so many bargain cabinets sag at the sink base first.

BluePrint boxes use 5/8″ plywood sides with a full 5/8″ plywood back, finished with an AA face-grade veneer on the show surface.

Plywood holds a fastener and shrugs off the odd spill in a way chipboard never will.

Face Frames, Doors, and Drawers

A face frame is the flat wooden frame across the front of the box that squares it and gives the hinges something solid to bite into. Ours are 3/4″ solid birch.

The face frame locks to the sides with a sliding dovetail, a tapered joint that slides into a matching groove, backed up with heavy-duty metal corner brackets.

You will notice what is missing there: cam locks, the little cam-and-dowel fasteners common in flat-pack furniture. Cam locks are fine in the right material, but in particleboard they work loose over time, so we leave them out.

Every BluePrint cabinet is framed, meaning it gets that face frame. If you are weighing framed and frameless construction, we compare the two elsewhere.

  • ●The drawer boxes are solid wood with dovetail joints at the corners, running on full-extension soft-close slides.
  • ●Doors are five-piece and full overlay, so the door covers most of the frame and the frame nearly disappears once everything is hung.
  • ●BluePrint offers eight door styles, from painted whites and greys to stained birch. The painted styles use an HDF frame with an HDF center panel, chosen because high-density fibreboard takes paint smoothly. Shaker cabinet doors are the most popular of the set.
  • ●Soft-close hinges and slides come standard on every cabinet, backed by a limited lifetime warranty on that hardware.

Composite Wood and Formaldehyde in Canada

One question almost nobody asks, and should, is what those wood panels give off.

Composite wood panels can release formaldehyde. Any composite wood product sold in Canada has to meet the limits in Canada’s composite wood emission regulations, in force since January 2023 and aligned with the American TSCA Title VI and CARB Phase 2 rules.

So a cabinet legally sold here has already cleared a binding Canadian bar. Ask any dealer to point you to the panel compliance records if you want the paperwork.

Why RTA Cabinets Cost Less

The savings are real, and they come from two places.

1 First, you supply the labor a factory would otherwise charge for, so the assembly cost comes out of the price.
2 Second, flat boxes ship far cheaper than built ones, because a truck holds many more of them and far fewer arrive damaged.

Those two savings are the whole reason the category exists.

What that looks like in dollars: most full BluePrint kitchen packages fall between $5,000 and $25,000 CAD plus HST, which works out to roughly $350 to $700 per linear foot.

A linear foot means one foot of cabinet run measured along the wall.

We put real layouts with real measurements on our published kitchen pricing page rather than hiding behind a “starting at” line. My own kitchen, for the record, was a $14,550 cabinet package.

How RTA Cabinets Go Together

Assembly is less work than most people fear, and more technique than most guides admit.

A base cabinet goes together in about 10 to 15 minutes, a wall cabinet in 7 to 10, once the hardware is sorted. A full kitchen of 20 to 30 units is a one- to one-and-a-half-day job for two people.

Sorting the hardware kit before you start is the single biggest time-saver, and it is a job a helper can do even if they have never held a drill.

Tools You Actually Need

The list is short:

  • ●a cordless drill
  • ●a rubber mallet
  • ●wood glue
  • ●a tape measure
  • ●an 18-gauge brad nailer

The nailer is the one tool most homeowners do not already own, and it runs about $150 at any hardware store.

Everything else is probably in your garage already.

A Technique the Instructions Skip

Here is the kind of detail that separates a clean job from a split face frame.

When you drive a screw into a solid birch face frame, spin the drill in reverse for a second first to seat the screw, then drive it forward. Birch is hard, and that half-second stops the frame from splitting where it will show.

Small moves like that are what our full step by step assembly guide walks through, with a companion video.

Are RTA Cabinets Good Quality?

Here is the honest answer: plenty of RTA cabinets are bad. The category earned its reputation.

Read enough renovation forums, and you will find warped panels, drawers gone crooked, and boxes that felt like cardboard the day they landed.

But look closely at those complaints and a pattern shows up. People did not get burned because the cabinet was ready to assemble.

They got burned because it was a cheap cabinet sold as a smart one. Bad materials fail whether a factory bolts them together or you do.

So the format is a red herring.

The questions that actually predict how a cabinet ages are the same three every time:

  • ●What is the box made from
  • ●How is it joined
  • ●Who is accountable when something ships wrong

A plywood box with a dovetailed frame and soft-close hardware will outlast a particleboard box with cam locks by a wide margin, no matter which one you assembled. For the local, skeptical version of this argument, we wrote a whole piece on whether RTA is worth it.

Who Should Buy RTA, and Who Should Skip It

RTA is a tool, and like any tool, it fits some jobs and not others. Here is a plain way to sort yourself.

If You Are… The Alternative Is Likely Your Pick RTA Is Likely Your Pick
Unwilling to assemble anything and happy to pay for the labor Buy pre-assembled, or hire the whole job out Not the right fit
Planning a genuinely one-off shape a standard box cannot make Commission true custom millwork Not the right fit
Out of time, without tools, and not hiring a helper Pre-assembled saves the weekend A stretch
Watching the budget and willing to build, or to pay an installer a few hundred dollars Overpaying for factory labor A clear fit
Set on a plywood box without a custom-shop price Rarely available at this price A clear fit
Buying from a town with no local cabinet shop Freight on built boxes gets expensive A clear fit, ships flat

Notice that three of those six rows point away from us. That is deliberate.

If you want zero assembly and an unlimited budget, we are neither your cheapest nor your easiest path, and we would rather say so now.

Frequently Asked Questions

A few questions we get once the basics are covered.

Can I Install RTA Cabinets Myself?
Often, yes. Assembling the boxes is well within reach for a careful DIYer with a drill and an afternoon. Hanging and leveling a full run of wall cabinets is the harder part, and plenty of people build the boxes themselves and hire an installer for the hanging. We refer independent installers, and you pay them directly, since we do not install.
Do RTA Cabinets Look Cheaper Than Custom?
No. A well-chosen door and finish read the same on the wall whether the box behind them was built in a factory or on your floor. The look comes from the door style, the finish, and the hardware. The assembly method does not show once the doors are hung.
What Happens if a Part Arrives Damaged?
Sometimes a piece ships damaged. Damage happens in this business, and pretending otherwise would be dishonest. The difference is who picks up the phone. As a local dealer, we put one person on your order and the follow-through, so a damaged panel gets sorted out instead of vanishing into a support queue.
Are RTA Cabinets a Good Choice for a Bathroom Vanity?
Yes, if the box is plywood. A vanity takes more standing water than almost any cabinet in the house, and particleboard swells once water reaches the core. A plywood box handles the splashes a sink throws at it far better. The same construction that matters in a kitchen matters more in a bathroom.
Do I Need an Appointment to See Them in Person?
No. The Fredericton showroom is open Monday to Friday, 9 AM to 4 PM, with no appointment needed. Bring whatever measurements and photos you have, along with your questions. You can open the drawers and knock on the boxes before you decide anything.

The Bottom Line

RTA cabinets ship flat and go together on site with hand tools. The letters tell you how the cabinet is delivered and nothing about how good it is. Quality lives in the box material, the joinery, and the honesty of whoever sells it. If you want to feel a plywood RTA box for yourself, come knock on one, and if RTA turns out to be the wrong call for your kitchen, we will say so.
