Which walls are load bearing? What are the gray items in Bedroom 1 and the primary bedroom closet?

you dont want an entrance to the master bathroom directly from the master bedroom?

• Unless you and S.O. are super tidy, you may regret a single sink MBA vanity.
• I also wonder if the current shower area will be too dark? Is the only glass the door?

I might kick around something like the following with a frameless glass shower. But I may not have understood all your dimensions- and only thought about it for 5mins. ✌🏻 Good luck.
