Solid Wood Cabinets: Which Parts Are Really Solid, and What Each Line Uses

Almost no solid wood cabinets are solid wood all the way through: in a well-built kitchen cabinet the door frames, face frame and drawer box are solid lumber, while the door's center panel and the sides, back and bottom are plywood, MDF or HDF. That split is deliberate. A wide solid board swells and shrinks with the seasons, and engineered panels don't.

We sell more than ten cabinet brands, so we have no reason to oversell one construction. Where a maker doesn't publish a detail, we say so instead of guessing. If you want the short version of box materials first, our guide to plywood, MDF and particle board covers them. For the box itself, see our sibling article on plywood kitchen cabinets.

Which Parts of a Kitchen Cabinet Are Solid Wood?

In a kitchen cabinet, the face frame, the drawer box and (on stained doors) the door frame are usually solid wood, while the wide panels are engineered.

Here are the five parts of a framed cabinet, with thicknesses from the spec books we hold. Frameless cabinets skip the face frame.

Every cabinet part that is solid wood is narrow: face-frame stiles are 1½ to 1¾ inches wide, and door stiles about 2½ to 3¼ inches. Every part that is engineered is wide and flat. That's not cost-cutting. It is how cabinetmakers solved wood movement long before particle board existed.

The framed-versus-frameless difference is in our framed cabinets guide, and what to look for in a drawer is in our dovetail drawer guide.

Why Aren't Cabinet Boxes Made From Solid Lumber?

Cabinet boxes aren't made from solid lumber because a wide board swells and shrinks across its grain with humidity, about a third of an inch on a 24-inch maple side, while plywood, MDF and HDF stay flat.

Wood takes on and gives off moisture until it matches the air around it, and almost all of the resulting movement happens across the grain, not along it. The USDA Forest Products Laboratory's Wood Handbook gives a simple equation for it: change in width = starting width × the species' dimensional change coefficient × the change in moisture content.

The Wood Handbook's Table 13–2 recommends interior woodwork be installed at about 8% moisture content in most of the U.S., with individual pieces anywhere from 6% to 10%. In damp, warm coastal areas the range is 8% to 13%.

Take sugar maple, a common cabinet hardwood. Its tangential coefficient in Table 13–5 is 0.00353 per percentage point of moisture. Run three widths through a 4-point swing, say 6% in a heated winter to 10% in a humid summer:

These maple figures are flat-sawn, the worst case. Quartersawn lumber moves along its radial coefficient, 0.00165 for sugar maple, so a bit under half as much.

Plywood avoids the movement problem because its veneers are cross-laminated: the Wood Handbook describes it as an odd number of layers with the grain of each layer at right angles to the next. The layers restrain each other, so the sheet stays flat. MDF and HDF avoid it because they have no grain at all.

Cabinet manufacturers acknowledge wood movement in their warranties. Fabuwood's Allure spec book says it is "very common for center panels on doors to shrink, expand or move" and that the panel "will return to its normal position within a year," and it treats a door warped up to ¼ inch as not defective.

J&K's spec book says hairline cracks "are unavoidable in wood cabinets" and that "every species and grade of solid wood" eventually shows them.

Both warranties exclude cracking around the joints of painted doors. If you live somewhere humid, our guide to cabinets for Florida humidity goes further.

What Do "All Wood," "Solid Wood" and "Real Wood" Labels Mean?

On cabinets, "all wood" usually means every part is a wood product, "solid wood" usually covers the doors and frames, and "real wood" means the visible face is that species.

None of these phrases has one industry-wide definition that a cabinet buyer can lean on, so read each one for what it literally covers. Here is how the wording usually maps to construction, based on the spec books in front of us:

The "100% solid wood" example is J&K Cabinetry, a line we carry and like. J&K's spec book says its cabinets "are superiorly constructed with 100% solid wood" and lists a ¾-inch solid wood door and ⅝-inch solid wood dovetail drawers.

The same J&K spec book lists ½- to ⅝-inch plywood boxes and ¾-inch plywood shelves, and its door page says the E-series doors are "constructed with plywood center panel," while the B- and S-series use an "ALL-WOOD reversed raised panel."

Read together, J&K's claim is about the doors and frames, and even there one series uses plywood for the panel. J&K is a sound cabinet. It just isn't solid throughout, and no stock line we know is.

So ask "which parts are solid wood?" rather than "is it solid wood?" If a seller's answer is only "all wood," ask what the sides are made of, because the real dividing line in the box is plywood against particle board. Our furniture board vs plywood comparison and particle board guide cover that side.

Is HDF Better Than Solid Wood for Painted Cabinet Doors?

For painted cabinet doors, HDF is often a better material than solid wood, because HDF has almost no seasonal movement to crack the paint at the joints.

Paint is a skin. When a solid wood panel or frame moves, the paint film over each joint has to stretch or split, and it splits. That is why the Fabuwood and J&K warranties exclude cracking around the joints on painted doors, and why several makers drop solid wood on their painted finishes on purpose:

• Fabuwood Luna: the Allure spec book says Luna doors use "Solid Wood Stiles & Rails (Stained Finishes) or HDF Stiles & Rails (Painted Finishes)," with a ⅝-inch moisture-resistant MDF/veneer center panel.
• US Cabinet Depot: "Our painted styles feature an all HDF door," including Shaker White, Shaker Grey, Shaker Dove, Shaker Navy and Shaker Black. The stained doors have solid birch frames, and most of them a veneered MDF center panel.
• Modernform Shaker: its FAQ says painted Shaker doors are high-density fiberboard, and stained ones are solid birch with a veneered MDF center panel.
• KCD Essential Builder: HDF stiles and rails with an MDF center panel. KCD's Premier series uses solid wood stiles and rails with an MDF panel.

What an HDF door gives up is the grain and the ability to sand down to bare wood later. So if you are buying painted cabinets, a solid frame is a nice extra, not a quality requirement. If you are buying stained cabinets, you want real wood on the face.

Our HDF cabinet doors guide explains the material, and painted vs stained cabinets covers the finish choice itself.

What Is Each Cabinet Line We Sell Made Of?

Most cabinet lines we sell pair solid wood door and face frames with an engineered center panel, solid wood dovetail drawers and a plywood or furniture board box.

The table covers every line we carry, filled in from the manufacturer's spec book, catalog or FAQ. "Not itemized" means the maker doesn't publish that part in the documents we hold, and your quote should state it. Our quality scorecard covers the boxes in more depth.

The line table shows three patterns. First, the solid frame with an engineered panel runs up to built-to-order lines: St. Martin uses an HDF panel inside a ⅞-inch solid frame, and so does NOMA.

Second, the same brand can be solid on one finish and HDF on the next, so look up your finish, not the brand. Third, solid wood drawer boxes are the norm everywhere except the metal-sided frameless drawers and Tribeca Americana's plywood ones. The real spread is in the box, which runs from particleboard on Tribeca Americana to ¾-inch plywood on NOMA and Ovela.

A note on US Cabinet Depot: its spec book FAQ says the framed boxes are "constructed from solid Birch hardwoods and furniture grade plywood." We read that as solid birch on the face frame and plywood for the panels, which matches the "½″ Plywood Box" listed on every framed door page of the same spec book. The US Cabinet Depot box is not a solid lumber box.

For the wood species themselves, our species comparison and white oak buying guide list which finishes are real oak, walnut or birch on the face and which are look-alikes.

What Does "Hardwood" Mean in Hardwood Kitchen Cabinets?

"Hardwood" in hardwood kitchen cabinets is a botanical term for the tree family, not a hardness rating.

The Wood Handbook defines hardwoods as angiosperms, trees whose seeds are enclosed in the ovary of a flower, and notes that some softwoods, such as longleaf pine and Douglas-fir, are harder than hardwoods like basswood and aspen.

To compare how well a cabinet face resists dents, look at side hardness, measured with a modified Janka test. The Wood Handbook's Table 5–3b gives these figures at 12% moisture, in pounds of force:

Every species in the hardness table is a hardwood, and red alder dents at about a third of the load hickory does. Hardness matters on a door that takes knocks, but finish and construction matter more to how long a kitchen lasts.

Species looks and costs are in our oak, maple, walnut and acacia guide, and individual species have their own pages, such as cherry cabinets and hickory cabinets.

What Are Real Wood's Pros and Cons, and When Is It Worth It?

Real wood's pros are grain you can stain and faces you can sand and refinish; its cons are a higher price, seasonal movement and natural color variation, so it pays off on stained cabinets and matters less on painted doors.

Match the material to what you want the cabinets to do:

For most kitchens, the best value is the combination almost every line already uses: solid wood door frames and face frames, an engineered center panel, solid wood dovetail drawers and a plywood box.

Real wood also varies from tree to tree, and the warranties say so. Fabuwood's and J&K's both treat differences in color and grain, mineral streaks and knots as natural rather than defects, and both note that colors may darken or lighten over time with sunlight and UV. A new door can therefore differ a little from your sample or from cabinets bought years earlier.

If you're shopping for all wood shaker cabinets in particular, our shaker cabinets guide compares the styles and prices across brands, and you can browse every wood-tone finish we stock on our wood kitchen cabinets page.

What Should You Ask Before Buying Wood Cabinets?

Before buying wood cabinets, ask what each part is made of on your finish and what the warranty says about wood movement.

Whoever you buy from, ask these six questions. A good seller answers them in writing:

1. What are the door stiles and rails made of on my finish? Not the brand in general, the finish you picked. Stained and painted can differ.
2. What is the center panel? Solid wood, veneered MDF, plain MDF, HDF or plywood.
3. Is the face frame solid wood, and what species? Matters most if you're staining.
4. What are the drawer boxes? Solid wood or plywood sides, how thick, and dovetailed or stapled.
5. What are the sides, back and bottom? Plywood or furniture board, and how thick.
6. What does the warranty say about wood movement? Look for the wording on panel shrinkage, hairline cracks at painted joints, and how much warp counts as a defect.

After the questions, hold a door. A $35 door sample shows you the frame, the panel edge and the back of the door, which tells you more than any listing. Samples are final sale.

Our guide to spotting quality cabinets has a ten-minute inspection list, and the CARB2 guide covers the formaldehyde rules that apply to the engineered parts.

Frequently Asked Questions

Are solid wood kitchen cabinets better than plywood?

Solid wood kitchen cabinets aren't simply better than plywood: solid wood is the right material for narrow parts like door frames, face frames and drawer sides, and plywood is better for wide parts like cabinet sides. Plywood's cross-laminated veneers stay flat where a solid board would move about a third of an inch across 24 inches. A good cabinet uses both. More on the box side is in our plywood cabinets guide.

Is plywood considered solid wood?

No, plywood is not considered solid wood. Plywood is real wood glued up from thin veneers with alternating grain, not solid lumber. Plywood does count as "all wood," which is why that phrase and "solid wood" mean different things.

Are there any cabinets that are 100% solid wood?

No stock or semi-custom cabinet line we know is 100% solid wood. Even J&K, which advertises 100% solid wood, lists plywood boxes and shelves. A truly all-lumber cabinet would be custom furniture work, built with joints designed to let wide parts move.

How can I tell if my cabinets are real wood?

You can tell if cabinets are real wood by checking the back of a door and the edge of the center panel, where solid wood shows grain that continues around the edges and end grain on the top and bottom of the door frame. On a painted door, that end grain often still shows as faint lines under the paint. Veneer shows a thin wood layer over a smooth brown core at a chip or edge. A printed laminate repeats its pattern and often has a seam at the edge. Inside the box, plywood shows layers at a cut edge and particle board shows chips.

What does "all wood cabinets" mean?

"All wood cabinets" usually means every part is a wood product and the box is plywood rather than particle board. The phrase doesn't mean solid lumber. MDF and HDF are wood fiber, so painted doors sold under the "all wood" label are often HDF or MDF.

Are real wood cabinets worth the money?

Real wood cabinets are worth the money for stained kitchens, where real grain is the look you pay for and can be refinished. In a painted kitchen, a solid frame is nice but not essential, because paint hides grain and HDF holds paint at the joints better.

How long do real wood cabinets last?

Real wood cabinets, like kitchen cabinets in general, are expected to last up to 50 years, according to the 2007 NAHB/Bank of America study of home component life expectancy; that figure isn't specific to wood. In practice the box, hinges and finish usually decide when a kitchen wears out. Solid wood frames add one advantage: they can be sanded and refinished instead of replaced.

Do solid wood cabinet doors warp or crack?

Solid wood cabinet doors can move a little, because their center panels shrink and swell with the seasons. Fabuwood's warranty doesn't treat warp up to ¼ inch as a defect. Keeping indoor humidity steady and leaving panels free to float keeps it small.

How do you clean and care for wood cabinets?

Clean wood cabinets with a soft, lint-free cotton cloth dampened with mild soap and warm water, then dry them right away. J&K's care guide also says to avoid dish cloths, sponges and ammonia-based cleaners, and its warranty treats indoor humidity outside 30–55% or temperatures outside 50–85°F as extreme. A humidifier or dehumidifier that keeps you in that range limits movement.

What is the best wood for kitchen cabinets?

The best wood for kitchen cabinets depends on the finish: oak, maple, cherry or walnut for stain, and maple, birch or an HDF door for paint. Among the stain-grade species, choose by the grain you like; our species comparison covers each.

Do you install the cabinets?

No, Captivating Cabinets does not install cabinets. We design, quote and ship cabinets to the 48 contiguous states, and your own contractor installs. In New Jersey, installation is available through our sister company, Captivating Construction Group.

How Can You See the Construction Before You Order?

You can check a cabinet's construction before ordering with a $35 door sample or a free itemized quote.

Tell us whether you want stained or painted, and our free 3D design service replies within two business days and usually returns renderings and an itemized quote, with the box and door materials named, within 24–48 hours of getting your measurements. You can also order a J&K door sample, a US Cabinet Depot sample or a Fabuwood sample for $35 each and look at the frame and panel yourself.

Built-to-order cabinets are final once the order is submitted. Before production, a cancellation is possible only if the manufacturer accepts it, and a restocking fee of typically 30% applies. Questions? Contact us or call (609) 900-3358.
