The answer to 'how long does sink last' is that a typical kitchen or bathroom sink can last anywhere from 10 to 20 years with proper care and maintenance. The lifespan of a sink depends on several factors, including the material it's made of, the quality of the installation, and how much use it gets.
Sinks made of stainless steel or porcelain tend to be the most durable and can last on the longer end of that 10-20 year range. Sinks made of cheaper materials like fiberglass or laminate may only last 5-10 years before needing replacement. Proper cleaning, avoiding abrasive scrubbing, and promptly addressing any cracks or leaks can help extend the life of a sink.
