In Switzerland, it is illegal to flush the toilet after 10pm in some apartment buildings
Switzerland takes noise pollution regulations extremely seriously. In many Swiss apartment buildings and residential areas, local ordinances restrict noise-making activities after 10pm — and flushing the toilet is considered a noise disturbance. The specific regulations vary by municipality and building type, but the principle of "toilet curfew" exists in Swiss residential law. Urinating while standing is also considered excessive noise in some situations. The Swiss commitment to collective peace is absolute.
A country known for precision instruments and punctuality applies that same rigor to the sound of water in pipes — maintaining community silence even from internal plumbing.
