How long do kitchen cabinets last?
Both baseline charts land on the same figure for kitchen cabinets: about 50 years. KraftMaid's Lifetime Limited Warranty sounds longer than that and in practice is very often shorter — it lasts "for as long as they are owned by you, the original purchaser", and the document closes with the sentence "This warranty is not transferable."

The gap: the paper says “Lifetime” — The lifetime here is an ownership test rather than a durability claim: the cabinetry is warranted free of defects in material or workmanship "for as long as they are owned by you, the original purchaser", and the last line of the document states that the warranty is not transferable — so it ends the day the house changes hands, whatever condition the cabinets are in. The exclusions cover most of what owners actually notice over decades: the natural aging and darkening of wood color and the inherent variation between pieces, which the paper calls the beauty of nature and not a defect; ordinary wear and tear; damage from misuse, alteration, or improper installation, storage or handling; anything bought without a finish; thermofoil damage from prolonged tobacco smoke; and any cabinetry bought before 1998. The remedy is a repaired or replaced part at the maker's option, and the document warns that replacement parts are subject to availability and may differ from what was originally supplied — a real limit on a 30-year-old kitchen. Labor to uninstall and reinstall is excluded outright, and commercial or business use drops the term to one year from purchase. Typical service life is still about 50 years.

Typical service life: about 50 years
InterNACHI's chart carries a flat 50 years for kitchen cabinets and the same 50 for modular stock cabinetry; NAHB's 2007 survey chart, reached independently through its own industry calls, prints 50 as well. Both put bathroom cabinets at 50+ and garage and laundry cabinets higher still — which is a statement about how hard a kitchen is used rather than about how the boxes are built. The cabinet industry's own standard, ANSI/KCMA A161.1, does not answer in years at all: it is a battery of pass-fail loading, cycling and finish tests that, in its own words, create "in accelerated form, the cumulative effects of years of normal kitchen conditions" on a finished cabinet.

Humidity separates a 20-year kitchen from a 50-year one. Solid wood doors and face frames move with the seasons and show it at the panel edges, where a thin unfinished line appears every dry winter and closes again in summer. Particleboard and MDF do not move — they absorb, and once an unsealed edge under a sink or beside a plumbing run takes on water it swells and never comes back. In a humid climate the sink base is very nearly the whole story.
What the warranty paper actually says
KraftMaid (Cabinetworks Group) (The KraftMaid Lifetime Limited Warranty) publishes a “Lifetime” limited, non-transferable, conditional warranty. The lifetime here is an ownership test rather than a durability claim: the cabinetry is warranted free of defects in material or workmanship "for as long as they are owned by you, the original purchaser", and the last line of the document states that the warranty is not transferable — so it ends the day the house changes hands, whatever condition the cabinets are in. The exclusions cover most of what owners actually notice over decades: the natural aging and darkening of wood color and the inherent variation between pieces, which the paper calls the beauty of nature and not a defect; ordinary wear and tear; damage from misuse, alteration, or improper installation, storage or handling; anything bought without a finish; thermofoil damage from prolonged tobacco smoke; and any cabinetry bought before 1998. The remedy is a repaired or replaced part at the maker's option, and the document warns that replacement parts are subject to availability and may differ from what was originally supplied — a real limit on a 30-year-old kitchen. Labor to uninstall and reinstall is excluded outright, and commercial or business use drops the term to one year from purchase.

What shortens it
- Water at the sink base — a slow supply or drain leak under the sink ends more kitchen cabinets than wear ever does
- Steam venting up from an appliance door opened at the end of its cycle, or a kettle under a wall cabinet, working on the underside and the door edge
- Particleboard and MDF boxes and shelves in humid rooms, which swell irreversibly once water reaches an unsealed edge
- Doors and drawers running on hinges and slides that were never readjusted after the house settled, so every close is a small impact against the face frame
- Sunlight through a window falling on one run of doors, which shifts the color of that run and no other — something the warranty calls expected rather than a defect
- Shelves left loaded past the point where the bow stops coming back
Signs of wear to look for
- Swollen, crumbling edges at the bottom of the sink base, or a floor inside it that gives underfoot
- Doors that no longer line up along a run, or that have to be pushed to stay shut
- Drawer boxes coming apart at the front joint, or slides that grind, tilt and drop
- Finish worn through to bare wood exactly where hands go — around the sink, at the trash pull, beside the range
- Shelves visibly sagging under everyday load
- Color drifted noticeably between the doors nearest a window and the rest of the kitchen
