Ever wondered why some toilet seats have an open front? This U-shaped design, common in public restrooms, has a fascinating history rooted in practicality and hygiene.

### Why the Open Front?
The “split seat” design first appeared in the late 19th century, becoming a public restroom staple thanks to the **1955 American Standard National Plumbing Code**. By 1973, the **International Association of Plumbing and Mechanical Officials (IAPMO)** also promoted its use.

### Hygiene Benefits
1. **Reduced Germ Spread**:
The open front minimizes direct contact with the seat, lowering the risk of contamination.

2. **Easier Cleaning**:
It provides janitorial staff easier access for thorough cleaning, especially in high-traffic restrooms.

3. **Convenience for Users**:
– Women can wipe more easily without touching the seat.
– Men avoid unwanted contact with the seat.

### Accessibility
For people with mobility challenges, the gap simplifies transfers from wheelchairs and reduces accident risks in crowded restrooms.

### Home vs. Public
Oval seats dominate homes for comfort, as personal toilets are easier to maintain. In contrast, open-front seats excel in public spaces for hygiene and functionality.
