First door on the left

Shelly makes her way into the first door on the left of the hallway. Pushing the door open she finds herself in a large nicely decorated bathroom, a huge shower/tub combo dominating most of the space. Another door heads out of the bathroom to somewhere else.

Looking back into the corridor Shelly figures that the door in the bathroom must lead into the same room that the next hallway door follows, so that could be her next stop, or alternatively maybe she should try the other side of the corridor.
