Toilet seat design may seem mundane, but its evolution sparks interest. The U-shaped, open-front design, common in public restrooms, has a practical purpose.
Since the late 19th century, “split seats” aimed to reduce germ transmission. The American Standard National Plumbing Code (1955) mandated open fronts for public water closets.
By 1973, U-shaped seats gained popularity. This design limits surface contact, reducing contamination risk. Easier cleaning and hygiene benefits make it ideal for high-traffic areas.
Open fronts also aid mobility-challenged individuals, promoting independence and safety. The design reduces accidents and discomfort.
While oval shapes prevail in homes, open-front seats serve public spaces well. Their practicality trumps comfort considerations.
