“WC” is understood globally, especially in Europe, Asia, and Africa. For many non-English speakers, it’s more recognizable than “Restroom” or “Bathroom.”
✅ Universal Simplicity
It’s short, easy to print on signs, and avoids potential cultural awkwardness in translation.
✅ Cultural Legacy
In older buildings, historical districts, and train stations — especially in the UK, Germany, France, and Italy — WC remains the preferred label.
