Rapida, I like those pictures!
Mediaman, high five on H2 and H6! Those were the ones that made the most sense to me. I would ask the builder about the 15" from center just in case. But quite frankly, I still think the tub going in a corner is the best use of space. Oh yeah, I forgot to ask if you plan to have a trashcan near the toilet. All of my bathrooms (except the guest one that doesn't have space) have a trash can for tissues and other stuff that can't be flushed-- toilet paper rolls, finished crossword puzzles, q-tips, etc). I was just thinking about the only good thing about my guest bathroom is that it has a recessed toilet paper holder. Doesn't quite fit the extra thick toilet paper rolls though.
I don't recall seeing the "today" picture with magazines. Maybe my brain is just out of it.
