Kitchen cabinet quality is essentially a function of the materials, construction methods, finish and craftsmanship used in the cabinet-making process. There's variability in all of these ingredients which results in a corresponding range of cabinet quality.
This web page is aimed at helping you get a better understanding of wood-based cabinet quality. It helps if you know some basics about cabinet construction and materials but if you don't, never fear.

Or, if you see some terms that you're not familiar with, see the kitchen cabinets glossary page.
Before we get too far into the subject of cabinet quality, it will probably help to get a firmer understanding of just what that term means. "Quality" is something that's hard to pin down because at its root, it's subjective. One person's view of good quality may be another's interpretation of just "fair" or even "poor" quality. However, everyone of us still knows 'good quality', (whatever it means to us), when we see it.
You've no doubt looked at a product of some sort that you felt either demonstrated good quality or it didn't. Being specific about what it was that brought you to that conclusion is a harder task however. In the end it was probably because it either "looked" a certain way (sturdy, good attention to detail, no flaws) or if you actually bought and used the product, it met or exceeded your expectations in some way. Maybe it lasted longer than you expected or performed it's job with no hiccups.
Kitchen cabinet quality is no different. You'll encounter a range of materials and methods of assembly and in the end, you'll have to judge whether the product meets your quality standards.
What we hope to point out here are the important characteristics that define kitchen cabinet quality and the variation within the quality spectrum.
(Also see the Publisher's Comments on defining cabinet quality at the bottom of this page).
To start with you might be asking "Aren't there any standards that define good quality?" The answer is yes, there are some standards established within the industry but they're not "rules" that must be complied with like airlines that must conform to FAA regulations.
The KCMA, a cabinet industry trade organization, has established criteria that must be met in order to meet their certification requirements. However KCMA certification is elective and the lack of it doesn't imply poorer quality. At a minimum it gives you some baseline for the level of quality and durability a particular certified cabinet line has achieved or that other cabinet products can be compared to.
Beyond that there's also some basic common-sense standards associated with cabinet quality that will help you discern between better and poorer kitchen cabinet quality. This gets back to the point about 'knowing quality when you see it'. For example, thicker materials will be sturdier than thinner materials or construction techniques like dovetail joints are more durable than glued butt joints. But despite those characteristics that are plain and obvious, there are others that you might not be aware of like cabinet box reinforcement variations and drawer slide ratings.
So what should you be looking for to discern good cabinet quality? Focus on what the the basic components like the cabinet box, drawers and shelves are made from and how they're assembled. Also pay attention to the finish, how it's applied and the coatings that are used.
So read on! Hopefully in the end you'll have a good understanding of the range of kitchen cabinet quality and which attributes are better than others.
In their most basic form cabinets are nothing more than boxes that are made in varying sizes and of different materials. However that's where the similarities end. How these boxes are held together and the materials they're made from vary among manufacturers and even among product lines at any given manufacturer.
When it comes down to the materials that make up the box, there's debate over which is best because it depends what "best" means to the individual. Consider the options: solid wood (for face frames), plywood, particle board and medium density fiberboard (MDF).
Some cabinets also use a material called 'hardboard' for floors and cabinet back panels.
The material cabinets are made from is important because it plays a key role in the durability, longevity and quality of service the cabinets provide. Material properties such as rigidity, screw holding power and susceptibility to moisture and humidity will vary based on the material used in the cabinet's construction.
With regard to the reinforcing features, material selection plays an important role too. Preferable reinforcing parts are made from solid wood or plywood that are secured into dado slots cut into the cabinet's side, front and back panels or attached with screws.
Less preferable are smaller, thinner reinforcing pieces made from particle board and stapled or just glued in place.
Some cabinet manufacturers make corner gussets from plastic. Thick, substantial plastic that is securely fastened to the side panels is preferable over flimsy plastic parts. Here again, your eye can usually spot the superior products over the inferior ones (keep asking yourself, "does it look/feel solid or flimsy?").
Larger corner gussets are more effective than smaller ones because they 'reach out' and support more of the cabinet walls that they're attached to. This does a more effective job in keeping the panels square and rigid, particularly as the size of the cabinet box gets bigger.
Compare the pictures on the right and left below representing variances in typical cabinet box reinforcement methods. Which looks more solid to you? It helps to shop around and compare cabinets to "calibrate" your own eye for discerning higher and lower quality cabinet construction.
|Differences In Corner Gusset Reinforcement Thickness And Reach|
|Variation In The Thickness Of Side Braces|
The reasons for this are because thicker, reinforced panels with a solid front frame make for a more rigid and sturdy box with less chance of the box going out of square.
Your cabinets end up holding a substantial amount of weight from stacked dishes to canned goods. The shelves that directly support that weight rely on the brackets attached to the sides of the cabinet box. Thinner panels might bow or twist, particularly if they're not reinforced in some way.
The thickness of typical cabinet box side panels varies by manufacturer and product line. Thicknesses you'll see are 3/8, 1/2, 5/8 or 3/4 inch thick. Back panels range from 1/8 to 1/4 inch thick. Thicker panels provide more rigidity.
For comparison purposes take a look at the relative thicknesses of these typical materials used in cabinet construction. As you can see there's a significant variation among them.
The 1/8" hardboard on the left is used in some cabinets for the back panel. Typical cabinet box side panels are made from 1/2" stock with available upgrades to thicker material.
Cabinet drawers work hard because they hold a lot of the everyday items we use such as cooking and eating utensils. Because they're opened and closed frequently they take more of a beating than some of the other cabinet components. Better drawer construction means more durable and longer lasting drawers.
Cabinet drawers aren't complicated and there's just a few points to focus on. Pay attention to how the drawer box is constructed and the kind of slides they're mounted on.
Dovetailed joints are the most durable (provided they're tight with no gaps or looseness). Doweled and rabbet joints are next down the line with the glued/stapled joints at the lowest end of the quality spectrum.
Much less durable methods involve just stapling and/or gluing the bottom panel to the drawer box.
Stronger more durable slides will use roller mechanisms that have steel ball bearings and have metal attachment fittings where they fasten to the cabinet box.
Plastic and nylon attachments and rollers will be less durable than metal.
While this isn't necessarily a durability issue as it relates to quality, having more drawer space by using undermount slides is usually preferable over a smaller drawer. Higher-quality cabinet lines use undermount drawer slides over side-mount slides.
Full extension and over-travel slides allow the drawer to be pulled all the way out (or past all the way for over-travel drawers) which affords access to the entire drawer all the way to the back.
With 3/4 or "normal" extension a portion of the drawer remains inside the cabinet. You'll have to bend over to see or fish out the contents in the back. The lower the drawer is on the cabinet, the more inconvenient this gets.
Adjustable drawer slides are another good feature to have. They allow the drawers to be realigned in height and side-to-side as needed should they go out of alignment over time due to wear or shifting.
Better quality drawer slides also include added features such as soft-close action which causes the drawer to close itself once it's pushed past a certain point.
Plywood and solid wood are the best choices for shelf material as they provide better rigidity than MDF or particle board for a given thickness and shelf span.
Obviously the thicker the shelf, the more rigid and less prone to sagging it will be. Also, shelves that have a reinforcing strip made from solid wood or plywood attached to the front edge or underneath are more rigid than shelves without this feature.
How a load is place on a shelf will determine it's strength and resistance to sagging. In the case of kitchen cabinets the load is the 'stuff' you store on the shelves like dishes and food items.
Don't underestimate the weight of some of these items - lift your entire stack of dinner plates sometime to get a feel for what your cabinet shelves experience. The weight of a stack of plates, bowls or canned goods can add up pretty quickly and the closer to the center of the shelf you store them the more strength that shelf will need.
In general, shelf thicknesses range from 1/2 to 5/8 to 3/4 inch. The thicker 3/4 inch shelves are the preferable option based on their increased rigidity over thinner shelves.
If you work with a custom manufacturer you should be able to specify whatever thickness you want. They should also be able to guide you on the best thickness for a given span length. Although most cabinet shelves top out at 3/4 inch thick, don't hesitate to go thicker on a custom cabinet if you need the extra support.
For adjustable shelves make sure you're satisfied with the clips that hold up the shelf. Metal clips are sturdier than plastic clips.
Shelves need to be strong but so does the hardware that holds them up. Look for metal supports rather than plastic. Also, look for supports that appear "right-sized" for the shelf span. There's no hard and fast rule here but brackets with a longer "reach" under the shelf are better than small ones, provided they're made from a solid material appropriate for their size.Note the small size of these shelf-holding pins in the picture on the right. Wider shelves and heavier loads might tax brackets of this size.
The way the brackets are held into the cabinet sides is also important. Long shelves that support more weight put a heavier load on the brackets.
Brackets that are just pins inserted into a hole in the cabinet sides aren't as durable as shelf standards.
Shelf standards are metal channels that are attached to the inside walls of the cabinet box that accept metal clips to support the shelves. In some designs they're recessed inside a dado cut into the cabinet wall.
They may be a bit more obtrusive looking but they offer a sturdier alternative than small pins pressed into a hole in the side panels of the cabinet.
A good quality finish not only makes your wood cabinets look nice but it also goes a long way in protecting your investment. Why is that? Well, consider the environment your cabinets operate in.
Have you ever had boiling pasta or lobster on the stove? Or maybe you have a stove-top grill. There's lots of moisture, greases, and temperature changes that occur in a hard-working kitchen. That's not to mention the many times the drawers and cabinet doors are opened and closed or leaned on with dirty or greasy hands. Then there's the occasional spill of vinegar or ketchup down the front of the cabinet door. A good quality cabinet finish will go a long way in making sure your cabinets aren't phased by this onslaught.
Note: you may see references to 'conversion' varnish or catalyzed conversion varnish. This is also a durable coating material.
Regardless of who you buy your cabinets from make sure you understand what they're finishing process entails. Good wood finishing, particularly when using coatings like a catalyzed varnish, requires knowledge, tools and the right conditions to achieve a quality result.
If you search for the definition of "quality" you'll likely come across a number of meanings. In my personal view, quality is very subjective and varies depending on the expectations of the person judging it.
The information above provides guidelines on what characteristics are "better" mostly from a durability standpoint, and in an absolute sense. In other words, for a given condition, a dovetailed solid wood drawer has greater strength and durability qualities than a particle board drawer with doweled and stapled joints.
But does that mean the latter won't do the job and last as long as you expect? That all depends on your expectations. Does it also mean it's "poorer" quality? Maybe yes for you but no for the next person.
Reading information that helps you learn about what to look for in cabinet quality is beneficial. But you're best served by it when you take what you've learned and go out and see it for yourself. I think the best way to educate yourself on kitchen cabinet quality is to "test drive" the product.
What I mean by that is to go out and look at a range of products and see for yourself whether they meet your definition of quality. Look at some base cabinets that don't have any countertops installed and see how the box is reinforced.
Does the panel thickness look adequate or does it seem flimsy?
Compare some cabinets with corner gussets made out of particle board and others made from solid wood or plywood. Which looks more solid?
Pull the drawers in and out. Do they feel smooth and rugged or flimsy?
Look at some cabinet displays in home centers that have some 'mileage' on them from browsing cabinet shoppers. Do they look tired? Are any hinges loose? What do you notice about them?
Of the top 25 cabinet producers (based on 2006 sales volume), all who had more than one product line used elements like all-plywood and dovetailed drawers combined with other higher quality features in their higher-end lines. At a minimum that says something about what the industry perceives as higher quality.
However in the end, the decision to go with cabinets made with plywood, particle board, MDF or a combination really comes down to what you believe constitutes "quality" in your mind. It's a matter of what you can afford and that really means striking a balance between what your budget will allow and the level of perceived quality and durability that suits you. Do you want cabinets that will last 30 years or do you need them to hold up long enough to do the job until you move in 5 years.
Bottom line, use the information here on cabinet quality to understand the differences that are out there and get a baseline for what's ok, good and better. Get out and look at the products. Then, let your common sense prevail. If the cabinet seems flimsy or the workmanship looks shoddy then the cabinet doesn't meet your standard for quality and you should consider another product.
Armed with information, you should be able to make smart decisions on the level of kitchen cabinet quality that works for you.
Good cabinets can be had from a variety of sources. You can start with "brand" cabinets that you'll find in home centers and remodeling firms and see what they have to offer. In most cases you'll find several tiers in their product lineup, usually embracing a 'good', 'better' and 'best' quality philosophy. The pricing will vary accordingly along with those tiers.
Don't overlook local cabinet shops however. If you work with a remodeling firm or contractor they might make their own cabinets or sub-contract with a local cabinet maker. That doesn't mean quality will be any less than name-brands. Local shops offer face-to-face service and many have sophisticated equipment that can deliver optimal cabinet quality.
