The life expectancy of a toilet is more than 100 years. In fact, a study conducted by the National Association of Home Builders determined that toilets can last indefinitely. The components inside the toilet tank, however, do need to be periodically replaced and have a much shorter life expectancy of about five years. Many toilets meet their demise long before the age of 100, however, and proper care is required to maximize the longevity of yours.
Keeping Your Throne
To increase the life of your toilet, use nonabrasive cleaners to avoid scratches. Throw away wire cleaning brushes as soon as the bristles deteriorate to the point where you can see the metal. Avoid leaning back against the toilet tank; never stand on toilet tanks or lids. Be careful when using tools on or near the toilet -- a dropped tool could crack or break the porcelain, causing irreparable damage. Never use cleaning tablets that are dropped into the tank as these can damage tank components. Handle the toilet tank lid with care; tank lids break easily when bumped and are heavier than they appear, weighing an average of 10 pounds.
