The previous layout was fine, but it felt a bit exposed. Also, the oval window clashed with the mirror above the sink.
I decided to close up the window, and use a miniature cork-sculpture screen from my collection to create some privacy for the toilet area. I had bought the screen a few months ago for $14.50 (+ $5 shipping) from eBay.
I am still playing around with the placement of the fixtures. I will let you know how it goes.
