What is the status of trough urinals in plumbing code?

The status of trough urinals in plumbing code is that they are prohibited. This prohibition is often rooted in health and sanitation concerns, as trough urinals can present hygiene issues compared to individual urinals. The design of trough urinals can lead to more significant challenges in maintenance and cleanliness, potentially creating an unsanitary environment in facilities where they are used.

Moreover, plumbing codes are focused on promoting sanitary conditions and minimizing the risk of contamination. Individual urinals usually provide better management of hygiene by allowing for easy cleaning and limiting the areas that come into contact with users.

In light of these considerations, plumbing codes tend to advocate for designs that prioritize individual user privacy and sanitation, thus making trough urinals not permissible within many jurisdictions.
