In Trosa there are public toilets in two places.
In the harbor between the bus stop and the harbor sheds you will find one of them. These are open between 6 am – 10 pm during June-August, then closes at 8 pm the rest of the year.
Next one is inside the library, next to Trosa square. The opening hours here are between 9 am – 6 pm on weekdays and 10 am – 16 pm on weekends.
The toilets are accessible with wheelchair.
