And the size of the shower would be 3’2” x 8 ( the width of the room). Could make it 3.5’ wide. Anyone have thoughts on that?

Seems like you can move the vanity to the right wall and square off the closet. More closet with no loss of function in the bath.

What are your restrictions? Does plumbing have to be where shown? What is the window like, how far from the floor? Does it have to stay as shown?

Why the strange nook in the closet to the right? What are your closet storage needs (long and short hanging, heights, drawers, shelves etc)?

What are your bathroom storage needs?

Big enough? Way big enough for me, with a lot of wasted space in the middle.

I would not like that there isn't counter space with that sink configuration. I would make the shower deeper if I could.

Way big enough for me too. Do you have storage for linens/towels!

Are you building a house or just a bathroom?

(that is a loaded question)

I wouldn't like that bathroom.  When I take a shower, I like hot water and a steamy shower stall and that big open shower would not suit me. The proportions of the shower just don't sit right with me, too long and too narrow. My shower is 42x60 and I can't imagine wanting anything longer than 72. A width of 36 is OK but no more narrow than that and 42 is quite spacious. 

I might try a 42 by 42 area inside the panel and 30 inch opening for a total size of 42x72. Use the remaining two feet for a nice linen cabinet.

It's plenty big. You can use the space better I think.

We recently remodeled master bath that was 71"x 17'. We used 7' of the 17' for large wet room with tub and shower. The vanity reaches from wet room for 7' with toilet at end. We installed a modern sleek stlye barn door mirrored on bathroom side with hardware on bathroom side to maximize space and maintain more traditional look in bedroom. We are totally happy with it.

Thanks everyone for the feedback! Super helpful! Just doing a bathroom/closet remodel. House has a funky 2nd story 2x6 random bump out which you can see in the picture. Single small vanity, small shower, pink jetted tub from the 90s. We have some plumbing and AC duct restrictions as most remodels do… The current bathroom runs the entire span encompassing the plans I showed all the way to the corner of the house. And the remainder is an oddly compartmentalized closet with three doors that drive us crazy. We are gutting the entire space and starting fresh. Tying to make the large but awkward shaped space more useful! Wish us luck!!!

Here’s a thought: cut off the part above the red line and make it part of the bedroom. Or closet or whatever that room is up there.
