You begin looking at a lonely little tree in a courtyard. Turn around to your left and move around the corner to the right. Once you've gone around that corner you should see an open door in front of you. Well, half open. Go inside that door and immediately through the open doorway on the right. Through that doorway you should enter a kind of bathroom-ish area. Step forward, across the central vanity island thing, and to the enter of-... "To the enter". To the entrance of the shower. Once you're looking into the tiled shower area you are done.
