How did the advent of modern restrooms impact the need for Powder Room Attendants?

The advent of modern restrooms, featuring improved plumbing and hygiene, reduced the necessity for Powder Room Attendants, who traditionally maintained cleanliness and provided personal services. As restrooms became self-sufficient and more accessible, the role diminished, shifting focus to automated cleaning systems and self-service options, ultimately leading to a decline in demand for attendants in public facilities.
