Bathroom Layout Help!

[Jeff Bridges]

Hey BP, I need help figuring out how to deal with a weird bathroom layout! Please provide feedback if at all possible. Older house with not ideal bathroom layout. Was thinking if there were better ways to re-position items and re plumb to allow for a cleaner layout. Let me know if I could leave it as-is or should try to change it.

Current layout (exterior wall with window is on top):

Here is my new proposed layout. I would need to plumb from the floor for both because that is an exterior wall on the top  Window would be behind the toilet (I'd put blinds/frosted glass filter):

let me know if you agree or have other suggestions!
