Before modern medical tests, people relied more on simple observation to monitor their health. This is why the European “shelf toilet” was created. Unlike modern toilets, it featured a flat platform that held waste before flushing, allowing users to check for signs such as blood, parasites, or unusual changes. The design was also associated with reducing splashback and making stool samples easier to collect.
As plumbing improved and hygiene preferences changed, toilets that washed waste away immediately became more popular due to better odor control, easier cleaning, and greater comfort. However, shelf toilets can still be found in older buildings in countries such as Germany, the Netherlands, Austria, and parts of Europe, where they remain a reminder of past approaches to health and sanitation.
