Second option What are the broken lines? Closets? You can't build closet in front of a window.........And you can't get a decent bath on 11 feet .........lose the tub , or make a tub/shower.. You need at least 30 inches width for the toilet to meet code. Fifteen from center, to any obstruction.Your plan has a "broom closet for a shower. Pick one. Skip the walk in closets for reach in. In both the hall space, and the bedroom.

Measurements must be accurate. Draw your plan again.
First: 6’ plus 16’ equals 22’, one foot more than the space you have. You must deduct the wall’s size, too, so your 21’ space minus the thickness of the wall will not give you 16’ of bedroom and 6’ width in the bathroom.
You show two small sinks crammed into the corner of the bathroom. You need storage in any bathroom. One sink in a vanity with 4-drawer storage on both sides is the minimum storage for a master bathroom. A good tub/shower combo is better than a separate tub and a small shower. A shower is used more often than a tub, so combine them in this small space, or eliminate the tub and have a better shower. You need space on both sides of the toilet.

Without actual measurements of all the walls doorways etc we have no clue how the space is BTW there is no way you will get all that into a bathroom that size so tub/ shower is the way to go there. I assume this is the main floor of the house since you want the french doors going to the back yard. What is it you want to access in the backyard ? IMO unless you have a hot tub to go to it really is a bit wasted expense since really access to the back yard is best in your entertaing space . Can you also post some pics of the space . Please make the measurements so we can read them

@JAN MOYER, @skunst2017 the broken lines are existing walls.

On the top, they are the dividers of the existing 2 bedrooms. The one's below are walls for the laundry room.

Who exactly has breakfast in bed?

............lol

More trouble than it's worth for most:) Now you have three messy areas! Crumbs in the bed, messed up bedroom, messy kitchen awaits. You need a hotel .

HAHAHA!!!

First plan is better -- that bottleneck of doorways in the second looks terrible, and the hallway already gives you some privacy. Bed on the right, long closet in the hallway. Dresser on the bathroom wall. Agree that your bathroom layout is unworkable on several fronts.
