Francesca: I didn't get inside the shower. I should have. It's probably a bit too square for a true B. Maybe it would work in a widebody or a small C. If you lost/moved the sink it might work on a standard B. It seemed like a better use of space than the bathroom in a pleasureway pursuit.
It would be nice if they had dimensions and things were drawn to scale. Based on the size of the bed it looks like it is about 38" x 48"
tatest: Is this bathroom any harder to find tank locations for than other Bs with a bathroom in center?
I wondered about the weight distribution thing as fresh drains and black/gray fill. How is that resolved on any RV? I guess it makes less of a difference on a heavy A/B/C than on a small light TT. Do any brand TTs do it better than others?
