Kitchen Cabinet Construction Checklist: 10 Specs to Check Before You Buy

Two kitchen cabinets can look almost identical in a photo and still be built very differently. Before comparing price, compare the construction.

This checklist covers the 10 cabinet specifications that homeowners, contractors and renovators should verify before buying RTA or assembled kitchen cabinets.

1. Cabinet box material

Start with the cabinet box—not the door colour. Common box materials include particle board and plywood. Each can be suitable when the panel, surface, edge treatment and hardware are appropriate for the project.

ShopKitchens offers particle-board and plywood options across compatible cabinet products. The selected product variant is the source of truth.

2. Panel thickness

Thickness affects the feel and construction of side panels, shelves and structural parts. Our supplied particle-board RTA documentation specifies an industry-standard 3/4-in cabinet box panel on the documented program.

Do not assume every accessory, back panel or drawer component uses the same thickness. Check the part being described.

3. Back-panel construction

The back of the cabinet is easy to ignore, but it affects squareness, installation and how the cabinet is fastened. Depending on the program, back-panel thickness and reinforcing rails can differ.

When comparing cabinets, ask whether the back is a full structural panel, a thinner back with reinforcing rails, or another system—and how the wall cabinet is intended to be mounted.

4. Edge sealing

Engineered panels need finished edges. Look for consistent edge banding on exposed and protected panel edges. The supplied ShopKitchens RTA construction documentation describes PVC edge sealing with smooth finished edges on the documented program.

Edge treatment matters particularly around everyday kitchen moisture. It does not make a cabinet waterproof, but it is an important construction detail.

5. Door-core material and finish

Do not assume that “Shaker,” “slab,” “matte” or “gloss” tells you the material. Those describe design or finish. Door cores can include HDF, MDF, particle board and other engineered panels depending on the series.

Use our door-style specification guide to compare exact construction.

6. Hinge adjustment and soft close

Concealed adjustable hinges make it easier to align doors after installation. Soft-close functionality can reduce slamming and improve day-to-day feel.

Check whether soft close is included on the exact cabinet or door program rather than relying on a site-wide assumption.

7. Drawer construction and slides

A drawer is more than its front. Compare the drawer sides, bottom, back, slide type, extension and soft-close function. The supplied RTA reference for our documented range includes a metal-sided drawer system.

Confirm drawer specifications on the selected product because specialty cabinets and accessories can differ.

8. Adjustable legs and leveling

Floors are rarely perfectly level. Adjustable cabinet legs can make base-cabinet installation easier by allowing the installer to level the cabinet run before fitting the toe kick and countertop.

The documented ShopKitchens RTA base program uses heavy-duty adjustable plastic legs.

9. Toe kicks, fillers and finished panels

A cabinet order is not complete just because the boxes fit. Most kitchens also need finishing parts such as:

• toe kicks
• wall and base fillers
• end panels
• pantry/tall panels
• crown, valance or other trim where used

Our supplied documentation shows a 3/4-in toe kick with sealed edges and a protective rubber layer at the bottom on the documented program. Exact finishing parts remain product-specific.

10. RTA, assembled or installed?

Finally, confirm what the price actually includes. RTA means ready to assemble; it does not automatically mean assembled or installed. Assembly, delivery and installation can be separate services.

Also check whether handles, fillers, end panels, toe kicks and accessories are included in a package or sold separately.

Bonus: certification and compliance claims

Do not judge cabinet quality from a row of logos alone. A standard or certificate may apply to a factory, a panel producer, a component, a test scope or a specific production period.

Our approach is to show documentation references with scope language rather than claiming that every cabinet carries every badge. If a project requires a specific current standard, ask us to verify the documentation for the product before ordering.
