Situation: I am facing a sink that is on top of a bathroom cabinet, while having a door behind me and a bathtub at my left.
Alternative situations: I am washing my hands in the sink on the right side of the toilet. I am admiring my face in the mirror in front of me, while the faucet on the sink is running.
Question: Which object on my left do I need to prevent water leaks on the floor during shower?
