I use mixed use washrooms (sink and toilet in same stall) when possible due to a health condition and really liked how the busy areas of Tokyo had these types of washrooms. There are these really advanced ones with automatic doors and a few different sinks for what looked like different needs. They had specialized taps and spray nozzles, specialized shapes.
What are those special sinks each used for? I’ve never seen them here in Canada, even in hospitals.
