Two summers ago, I decided to build my own kitchen cabinets. From scratch. Sheets of plywood, a borrowed table saw, and a stack of YouTube videos.

I figured it would take a few weekends and save me a fortune.

It took four months. My garage looked like a sawdust storm hit it. And when I added up every receipt at the end, I was surprised by what I found.

If you’re torn between building a do it yourself kitchen cabinet setup and buying RTA (ready to assemble) cabinets, this post is for you. I’ll walk you through the real costs, the real time, and the stuff nobody mentions until you’re halfway in.

First, What Are We Comparing?

These two terms get mixed up a lot, so let’s clear it up.

DIY cabinets means you build the cabinets yourself from raw materials. You buy the plywood, cut every piece, assemble the boxes, build or buy the doors, and finish everything.

RTA cabinets come flat-packed in boxes. All the pieces are already cut, drilled, and finished at a factory. You just put them together, kind of like big, sturdy furniture kits.

Both options save money compared to custom cabinets. Both involve work. But they’re very different projects.

The Cost Breakdown

Let’s talk money, since that’s why most people look into this in the first place.

What a DIY Build Really Costs

When people price out a do it yourself kitchen cabinet project, they usually just count plywood. That’s where the trouble starts.

Here’s what my 10-foot by 12-foot kitchen (about 20 cabinets) actually cost:

  • Plywood: About 22 sheets of 3/4-inch cabinet-grade plywood, plus some 1/4-inch for backs. Roughly $1,900.
  • Hardwood for face frames: About $400.
  • Doors and drawer fronts: I ordered these from a door maker instead of building them. Around $1,600.
  • Drawer slides and hinges: Soft-close everything. About $650.
  • Finish supplies: Primer, paint, sandpaper, brushes, a paint sprayer. About $450.
  • Glue, screws, edge banding, and wood filler: About $200.
  • Tools I had to buy: A pocket hole jig, clamps, a good blade, a track saw. About $700.
  • Mistakes and do-overs: I wasted two full sheets of plywood and one drawer box. About $250.

Total: around $6,150.

If you already own a nice set of tools, you could knock that down to maybe $5,000. If you build your own doors, you could save some more, but that’s a whole other skill.

What RTA Cabinets Cost

For the same kitchen layout, I priced out solid plywood RTA cabinets from a few well-reviewed online sellers. The quotes came in between $5,500 and $7,500, with shipping. That included:

  • All boxes, already cut and finished
  • Doors and drawer fronts
  • Soft-close hinges and slides
  • Dovetail drawer boxes

Budget particleboard RTA cabinets are even cheaper, around $3,000 to $4,000 for the same space. I wouldn’t recommend those for most kitchens, but they’re out there.

So Which Is Cheaper?

Here’s the honest answer. They’re closer than you’d think.

A careful DIY build with tools you already own can save you a little money compared to good RTA cabinets. Maybe $1,000 to $2,000 on a medium kitchen. Once you buy tools, add finishing supplies, and factor in mistakes, the savings shrink fast. Sometimes they disappear completely.

The Time Breakdown

This is where the gap gets huge.

DIY Time

My do it yourself kitchen cabinet project took about 220 hours. Here’s roughly where that time went:

  • Planning and drawing plans: 15 hours
  • Buying and hauling materials: 10 hours
  • Cutting all the parts: 40 hours
  • Building boxes and face frames: 60 hours
  • Sanding, priming, and painting: 55 hours
  • Building drawers and installing hardware: 25 hours
  • Fixing mistakes: 15 hours

That doesn’t include actually installing the cabinets on the wall.

If you’re working weekends only, 220 hours is about four to six months. That’s a long time to live without a working kitchen, or to cook on a hot plate in your basement.

RTA Time

RTA cabinets usually take 30 to 60 minutes each to assemble once you get the hang of it. The first few take longer. For 20 cabinets, figure around 15 to 25 hours of assembly.

No cutting. No painting. No sanding.

Most people can get a full set of RTA cabinets assembled over one or two weekends. Some companies even sell them pre-assembled for an extra fee.

Which One Is Easier?

This one isn’t close. RTA wins.

What Makes DIY Hard

Building cabinets from scratch takes real woodworking skill. You need to:

  • Cut perfectly square. If your cuts are off by even 1/16 of an inch, your boxes won’t be square. Then your doors won’t line up.
  • Plan your cut list. You have to figure out how to get every piece out of each plywood sheet without wasting a ton.
  • Get a smooth finish. Painting cabinets so they look factory-made is tough. Brush marks and drips show up fast on a flat door.
  • Have space. You need room to lay out full plywood sheets, cut them safely, and let painted parts dry without dust landing on them.

I’ve done a fair amount of woodworking, and I still made mistakes. If you’ve never used a table saw, a full kitchen isn’t the place to learn.

What Makes RTA Easier

With RTA, the hard stuff is already done. The factory cuts every part with machines that are far more accurate than any home setup. The finish is sprayed in a clean booth. The holes for hinges are drilled in the right spot.

Your job is mostly following instructions, using a drill, and being patient. If you’ve put together a dresser or a bookshelf, you can handle RTA cabinets.

That said, RTA isn’t “no skill.” You still need to:

  • Read instructions carefully
  • Use wood glue where it says to
  • Keep each box square while the glue dries
  • Install them level on the wall, which is the trickiest part for both options

Quality: Does One Come Out Better?

This depends on two things: what RTA brand you buy and how skilled you are.

A careful DIY builder using good plywood can make cabinets that last 30 years or more. You control every detail. You can pick thicker panels, better slides, and exactly the sizes you want.

Good RTA cabinets use solid plywood boxes, dovetail drawers, and quality hinges too. The big advantage is consistency. Every box comes out the same because a machine made it.

Where DIY really shines is custom sizing. If you have an odd 27-inch gap next to the stove, you can build a cabinet to fit it exactly. RTA cabinets come in set sizes, so you’ll use filler strips to close the gaps.

When DIY Makes Sense

Building your own cabinets is a good choice if:

  • You already own a table saw, track saw, or similar tools
  • You genuinely enjoy woodworking and see this as a fun project, not a chore
  • You have a garage or shop space you can tie up for months
  • Your kitchen has strange sizes or angles that stock sizes won’t fit
  • You’re not in a rush

It’s also a great choice for smaller projects. A laundry room, a garage storage wall, or a bathroom vanity are perfect for learning. You build skill without the pressure of a whole kitchen.

When RTA Makes More Sense

RTA is probably the better pick if:

  • You want a working kitchen in weeks, not months
  • You don’t own (or don’t want to buy) a lot of tools
  • You want a smooth, factory-quality finish
  • You have a standard kitchen layout
  • Your free time is limited by work, kids, or life in general

For most homeowners, this is where things land. RTA gives you about 80 percent of the savings of DIY with a fraction of the time and stress.

A Middle Option Worth Knowing About

Here’s something I wish I’d known before I started. You don’t have to pick one or the other.

A lot of people do a mix. They buy RTA cabinets for the main runs, then build one or two custom pieces themselves. Maybe a built-in bench, a custom island, or a cabinet to fit an odd corner.

Another option is building your own boxes and ordering doors from a door company. That’s what I ended up doing. Doors are the hardest part to get right, and the part everyone sees.

My Honest Take

Would I build my own kitchen cabinets again? Probably not for a full kitchen.

I’m proud of how they turned out, and I learned a lot. But when I add up the time, I basically paid myself about $5 an hour in savings. My family also went four months with half a kitchen, and they’ll remind you of that.

If you love woodworking and have the time, a do it yourself kitchen cabinet project can be one of the most rewarding things you’ll ever build. If you mostly want a nice kitchen for a fair price, go with good plywood RTA cabinets. Spend your extra energy on a clean install, nice hardware, and some solid trim work.

Either way, you’ll save a lot compared to custom. Just pick the path that fits your skills, your schedule, and your patience.
