You're starting in a very minimalist closet. Turn directly behind you, and there's going to be a hallway. You'll notice that there's an opening on the left. So, it's the first opening on your left. Go through that doorway. When you walk into this room, you'll see it's a bathroom. There's a large, white, freestanding tub across from you. Go stand up next to that tub. You now should be  close to the tub, and the gray marble shower. This is your ending point.
