The answer to 'sink replacement frequency' is that the typical lifespan of a sink is 10-15 years with proper care and maintenance. Sinks are designed to last for many years, but factors like material, usage, and water quality can affect their longevity. Porcelain, stainless steel, and granite sinks tend to have longer lifespans than basic laminate or enamel sinks.
Over time, sinks can become cracked, chipped, or worn down, especially if they see heavy daily use. Proper cleaning and avoiding abrasive scrubbing can help extend the life of your sink. However, eventually all sinks will need to be replaced, either due to wear and tear or if you want to update the look of your kitchen or bathroom.
