If I generalize a bit for Sweden, small restaurants and shops generally only have a single bathroom. Fast food restaurants, schools/universities, work places, and train stations tend to have one or two large single-occupant unisex accessibility room and several smaller single-occupant unisex rooms. Airports, high-end restaurants and shopping malls tend to use US style of single-sex bathrooms. Tourist areas, venues for people to drink, larger gas stations, and bus stations often come with a urinal room for men-only, an unisex accessibility room, and one or two smaller unisex rooms.

The larger accessibility room is also for parents with small children.
