The answer to 'when to replace sink' is that you should typically replace your sink every 10-15 years, or sooner if it becomes significantly worn, damaged, or outdated. Sinks can last a long time with proper care and maintenance, but eventually the materials will start to deteriorate, leading to cracks, leaks, or other issues. Replacing an old, damaged sink can improve the look and function of your kitchen or bathroom.
Some common signs that it's time to replace your sink include visible cracks or chips in the surface, difficulty keeping the sink clean, frequent leaks or clogs, and an outdated or mismatched appearance compared to the rest of your decor. If you notice any of these problems, it's a good idea to consider replacing the sink rather than trying to repair it, as a new sink will provide a longer-lasting solution.
