The answer to 'lifespan of toilet' is that a well-maintained toilet can typically last 10-15 years, or even longer. Toilets are generally very durable and can withstand regular use with proper care and maintenance. The lifespan of a toilet can vary depending on factors like the quality of the toilet, how often it's used, and how well it's maintained.
Proper maintenance, such as regularly cleaning the tank and bowl, fixing any leaks, and replacing worn parts like the flapper or fill valve, can help extend the life of a toilet. With good care, many toilets can remain in service for 20 years or more. However, over time, the internal components may wear out and need to be replaced, or the toilet may become outdated and need to be upgraded.
