The answer to 'lifespan of toilet' is that a well-maintained toilet can last 10-15 years on average. Toilets are built to be durable, but their lifespan depends on factors like the quality of the toilet, frequency of use, and how well it's maintained. Higher-quality toilets made with more durable materials can last even longer, up to 20 years or more with proper care.
Over time, the internal components like the flushing mechanism, tank gaskets, and seals can wear out and cause leaks or other issues. Replacing these parts can extend the toilet's lifespan, but eventually the entire unit may need to be replaced. Signs it's time for a new toilet include cracks, constant clogs, or poor flushing performance.
