You begin looking out of an open white door. Turn slightly to the left and move into the open white door to your left, but as soon as you're in that door turn back, and move through the open door to the right. Step into the bathroom further, and turn around that open door that's straight in front of you. Requires kind of a weird angle, but... You'll be stepping past some bathrobe nex- Past some bath robes next, and a shower on your right, and you should end up right in front of a toilet in its own little room, and once you are standing in front of that toilet in its own little room you are done.
