Will you be able to get furniture into the bedroom? Is that a free-standing tub? If so, how will you clean behind and next to it? Have you thought about solatubes for natural light at the vanity area?

My first thoughts... do you ever have to get up in the middle of the night to use the toilet? Boy howdy, that's at least 20 feet. One of the benefits of having a master suite is a convenient bathroom that's not down a hall.

Secondly, I can't imagine the best place to put a pretty tub is at the front of the house, but maybe you're building on acreage?

It seems very constricted to me the way the bathroom is carved up. I don't know what the purpose is of that walled off space immediately to the left of the tub, but I would eliminate that wall and have the bathroom much more open. I would also have the vanity extend all the way to the wall that has the pocket door, and have double sinks.
