This room started off as a former lobby for an office, with door and window facing front.
The shower ended up where the door is, and the toilet and vanity against the (former) brick wall to the far right.
To the left, (picture above) is the best shot possible of the shower. This is looking directly where the door above used to be.
To the right, the window is smaller, the walls finished with tin panels, and stained oak trim.
Below is the vanity set to the right of the toilet.
