Trapped

You sprint to the door and throw it open. It turns out it was unlocked. You dash through and close it right as the mystery person enters the lab you were in. You look around and find yourself in a new room. It was made of ceramic tiles, wall to ceiling, with a drain in the middle. It reminded you of a shower room in High School locker rooms. You notice a hose in the ceiling. It seems to be alive, looking around and moving on it's own. It hasn't noticed you yet. You see another door across the room. How do you get there?
