IMO bathrooms have a toilet no one should be using the toilet when someone else is in the space so if open feeling is what you want then forget closing off the toilet view from the shower .A counter deth fridge would eliminate that silly jog in the wall to keep the shower all one plane.

A different question about the refrigerator: are you really allocating 40 inches of depth for it and the pantry? I just measured, and from the wall to the front edge of my very ordinary refrigerator is 32 inches (not counting the handles). And would the pantry be a roll-out? That is too deep for a reach-in pantry but not wide enough for a walk-in.

I don't see any real problem with the master bathroom.

Thanks @Patricia Colwell Consulting -- we came to that conclusion as well re: the toilet. We've decided to go with glass for the full wall to keep it open and eliminate the pony or full wall.

@Paul NY 5b-6a - agree, only 32" for the fridge! Not sure why they marked 40 initially. Even though it makes for a silly jog, we want to keep the deeper fridge.

Pantry will only be ~24" deep for that exact reason - we'll likely put a linen cupboard in the hall bath that backs up to that space.

Updated floor plan for the bath attached. We'll use the "dead" space for a couple niches (shaving + soaps), and maybe put some little shelves on the side wall facing the toilet or something (I'll leave that to the designer).

Thank you both for your help!
