where is the door in relation to the window?

The door is directly opposite of the window on the other 10' wall but can be easily moved within that 10' wall.

IMO you will not have a walk in closet in that space but we need a to scale floor plan with windows doors and plumbing all marked and measurements of walls windows door ways.

Ok, thanks Patricia, I'm new to all of this!

how wide is the window?

The window is 36 inches wide.

Wouldn't matter. No walk in, reach in only. Not big enough.

What about something like this? You could use a pocket door for the closet. If you use glass for the wall where the shower meets the vanity, and of course a glass door, I think you'd get plenty of light.

Thank you, thank you, thank you all for these fantastic ideas!!!
