To dream of a public bathroom represents a disorderly attempt to cleanse negative thoughts, emotions, or situations. Life circumstances or bad habits aren't supportive of positive changes. You may have other problems, other people, or other situations that are interfering with your ability to smoothly fix an issue.
A public bathroom is a sign that more effort is needed to confront issues or that a current situation is unsupportive of progress.
