I have only seen the trailer for this movie, so I can’t really summarize the whole plot. The movie is in German, I think, but it could also be Dutch or Flemish. A strange/looking man moves into the home of a family and he proceeds to dominate the family’s life. The man looks like a homeless person, with a long beard, he is very dirty and wearing hardly any clothes if I remember correctly. He doesn’t speak. In one scene I think he is taking a bath in the family’s tub. From what I remember of the trailer the man is not really a man but some sort of mythical creature, but having not seen the film itself, I cannot be sure.  I think the title is a single (odd) word, but I could be wrong. I think it came out within the last five years, but it could be a few years older than that. Please help me remember what movie it is!
