I wasn't loving the long hall on the schematic until I saw the inspo pic. Here's another idea for you. How about widening the hall to include built-ins along the outside of it? The bath and closet have the room to lose 2 ft. It would just embellish the dressing room feel to it.

Not loving the toilet/shower room. They both look cramped. I do not like a streamy bath and this looks like it would stay humid for ever after my DH showered! Upside I would not be doing my hair around the steam/humidity. The toilet is far away from the bed for those urgent trips.

Odd idea. Switching the bath to the closet area and having that bath area be a closet within a closet. Could be overflow seasonal storage, a safe room depending upon where you live and the rest of the house, a spouse's closet.

You would of course put the bed on the opposite wall.

Move the toilet to the corner to the right of the door, with the shower now in front of you as you walk in. Much nicer view, feels more private for the toilet.

Steal a few inches to make the hall a bit wider. You may be passing each other in the hall, carrying laundry, etc, so make it pleasant. Hang a mirror across from the closet door for a better-lit distance view.

Is there a roof above this space? Consider solar tubes for the hall.

Instead of the hallway on the side, consider it running down the middle of the space.

Starting from bedroom, you put his/her closets, shelving on each side of the hall way...no need for doors or use pocket doors. From there the hall leads into the bathroom.

Since the bedroom location and suite entry are fixed, I would compare the layouts with someone standing at the vanity and every drawer and door drawn open. The route to the bedroom needs to work during actual use, not just when everything is closed. A tape outline of the cabinet depth and an open drawer can make that comparison much clearer.

For the mirror wall, ask for a simple elevation showing the sink centers, mirror edges, and light fixtures before the electrical locations are settled. If you want medicine-cabinet storage, include its depth and full door swing so it does not conflict with a side wall, faucet, or sconce. The AI images can help convey the look, but those measured drawings are what will tell you whether the storage and lighting fit.

Thinking about the center hallway makes me wonder. If the walk-in is 6’6” wide, with handing on both sides, that leaves 3’ to stand in, in the middle. If this is for two people, that’s tight.

Reach-ins along one wall, with the bathroom along the other wall, might work well? image for concept only, obviously, i didnt place a door to bathroom, just to contine yet another way of looking at it.

The hallway in your drawing is too narrow. Your inspiration pic shows an expansive hallway - 3'2" will be very tight. Consider adding at least a foot more of width to the hallway.

Can the wall between the proposed shower/toilet area and the rest of the bathroom be removed? It feels like the shower and toilet are a bit of a squeeze in that area while the outer area - where your vanity(ies) will be is overly spacious. If you can take down that dividing wall, and the door into that area it opens up the space completely. Put the shower across the back wall of the space, not the side as shown and it could be made deeper - a little more luxurious feeling. Then reconfigure the vanities and toilet for better use of space. I'd put the toilet behind the door so that it is hidden by the swing of the door. I never like to see the toilet front and center when looking into a washroom. Move the long vanity to the wall you see as you walk into the bathroom.

That would likely free up some additional floor space that could be used for the closet - especially if you make the hallway wider.
