The Mystery of Basement Toilets in Old Homes
Growing up in a 100-year-old house, I noticed a strange feature in the dark, unfinished basement: a lone toilet tucked in one corner. We never used it, so I paid little attention. But as an adult renovating old homes, I began to wonder—why did some older houses have a toilet in the basement with no attached bathroom?
Pittsburgh Potties: A Worker’s Convenience
These basement toilets are often called “Pittsburgh potties.” They appeared in homes with a separate basement entrance from the outside. Workers, particularly steelworkers in Pittsburgh, could enter through this basement door, use the toilet, and remove their dirty work clothes before stepping into the cleaner areas of the home. This simple solution kept the main living space tidy and practical.
A Safety Feature Across North America
Basement toilets also served another purpose far beyond Pittsburgh. Before World War II, city sewer systems struggled to keep up with the growing number of homes. According to the Calgary Real Estate Board, “When these homes were built, city sewer systems were crude, unreliable, and prone to backups. When backups occurred, sewage would overflow from the lowest fixtures. The basement toilet acted as a safety valve—right above the sewer line from the street.”
By placing the toilet in the basement, homeowners avoided sewage backups in living areas. Basement floors, typically stone or concrete, were easier to clean and less stressful to deal with, making this design both clever and practical.
Modern Times: A Forgotten Feature
Today, most Pittsburgh potties are no longer in use, and many have been removed entirely. Still, if you ever explore the basement of an old house and spot a seemingly random toilet, it wasn’t there by accident. These fixtures had clear purposes—either for worker convenience or as a safety feature against sewer backups.
Bonus Mystery for Old House Lovers
For those fascinated by vintage homes, basement toilets are just one of many curious features. Next time you see small galvanized pipes in an old house, you’ll know there’s often a practical story behind them too!
