What are the three cabinet grades?
Stock cabinets are built ahead of time in standard sizes and sold assembled or ready-to-assemble at home centers, with limited colors and styles. Semi-custom cabinets are ordered from a manufacturer's catalog and built to order, with more sizes, finishes and accessories; Consumer Reports says many use face-frame construction and calls them a sound choice for most kitchens. Custom cabinets are designed and built for your room by a cabinet maker, so any width, height, wood or finish is possible.
Consumer Reports notes that premium semi-custom lines offer widths in 1/4-inch increments rather than the usual 3 inches, and can cost as much as some custom cabinets. Fixr notes you can also mix custom and semi-custom, for example custom pieces for an island or an odd wall and semi-custom boxes elsewhere, to keep costs down.
Plywood, particleboard or MDF: which box material is better?
Consumer Reports calls plywood the higher-quality box material and favors 3/4-inch plywood shelves, warning that 5/8- or 1/2-inch particleboard shelves may sag and that stock cabinets are often thinly veneered particleboard. WoodBin notes that plywood is stiffer than particleboard and that particleboard creeps more under long-term load. MDF is smooth and stable, which makes it a common choice for painted doors and panels, but it doesn't tolerate water; Fixr notes water-damaged MDF and laminate cabinets are usually better replaced.
All three are composite wood products regulated in California. The Air Resources Board's Phase 2 formaldehyde limits are 0.05 ppm for hardwood plywood, 0.09 ppm for particleboard and 0.11 ppm for MDF, and the EPA's TSCA Title VI rule requires compliant panels to be labeled.
Face-frame or frameless cabinets?
Framed cabinets have a box with a solid-wood face frame on the front, and the doors and drawers attach to that frame. Frameless cabinets, also called European style, skip the frame and mount doors directly to the box, which gives a more contemporary look and easier access inside. Consumer Reports notes the lack of a face frame can reduce rigidity, so better manufacturers use thicker box sides.
Inset or overlay doors?
Inset doors sit flush inside the face frame; overlay doors sit on top of it. Partial overlay leaves part of the frame visible, and full overlay covers nearly all of it and needs hidden hinges. Angi says inset cabinets usually cost 15% to 30% more than overlay and can take longer to build, because the doors must be fitted precisely. That small gap also matters in Sacramento's climate: Angi notes inset doors can stick when humidity makes the wood swell.
Which finishes last: paint, stain, thermofoil or laminate?
Paint gives a solid color, but on five-piece wood doors, hairline cracks at the joints are common; Superior Cabinets calls them a normal characteristic of painted wood, not a defect, which is why many painted doors use MDF center panels. Fixr says laminate or thermofoil is the cheapest refacing material but the least durable, and it can peel with moisture or heat.
How long does each type take?
Stock cabinets are often available right away. Fixr's 2025 custom-cabinet guide says semi-custom cabinets average 6 to 8 weeks and custom cabinets 10 to 12 weeks from order to installation-ready, while its 2026 installation guide gives 6 to 12 weeks for custom. Add time for measuring and design approval before the order, and for installation and any permitted plumbing or electrical work after.
How can you judge quality in a showroom?
Pull out a drawer and open a door. Consumer Reports looks for solid-wood drawer sides with dovetail joints and a plywood bottom set in grooves on all four sides, full-extension drawer guides, doors with solid-wood frames, 3/4-inch plywood shelves and sturdy mounting rails. A KCMA A161.1 certification seal means the cabinet line's structure, drawers, doors and finish passed tests that simulate years of use.
