The lifespan of your cabinets depends heavily on how they’re built. High-quality custom cabinets — especially those made with plywood boxes, solid joinery, and durable finishes — can last 40 to 50 years or more with normal use.

Over time, the finish may need refreshing, but the structure itself usually holds up extremely well.

By comparison, lower-quality cabinets, particularly those made from particleboard, tend to show wear much sooner — often within 10 to 25 years depending on construction quality, with particleboard in high-moisture areas like around sinks and dishwashers falling toward the shorter end of that range.

In other words, the materials and construction methods make a big difference in how long your cabinets actually last.
