OK, I may be the only dissenter here, but I actually like the third one best. And, then I wouldn't paint the walls the aqua, I'd go with a neutral, and try and find aqua towels and accessories. To me there is more of a design appeal, with the third one, second one is safe, and the top one looks disproportionate. I think the aqua pops more as an accessory rather than the wall colour. Having said that, I just went to a linens store yesterday, and couldn't find ONE bathroom accessory or towel in the cranberry I was contemplating as an accent for my basement bathroom which right now if completely neutral except for some colour in the granite countertop. That had me thinking maybe I shouldn't do that colour in an expensive tile accent. I love changing bath mats, towels, etc. What other colours could you use with that aqua in the future, if you would like to freshen things up, or want a change?

Yes Island all over the place but starting to narrow things down (I hope). Good news is we are still awaiting the permits to get started so we can keep changing our minds on the cheap. The cabinets are that color sort of-- actually they are a bit lighter and less creamy in real life. That said though, we keep looking at other options b/c the Nougat/cabinet match isn't quite perfect-- still a bit of a warm and cold conflict as you astutely pointed out. Light grey/taupe tiles look really good with the Nougat esp with a white grout. Piatra Grey and Raven, on the other hand, look great with the cabinet color but feels a bit more formal than we were attempting. The crackle blue tile is gorgeous and might work if we confine the tile to the behind the range back splash area-- perhaps. Might be too blue though. If we can get comfortable with Nougat or another light color counter (London Grey and Stellar Snow don't really work either) then we'd run the subway up and around the window (I think) Layout... The view isn't ocean as we are on a cove in a salt pond. No need to improve that part at least : )

Personally, I like the one on the right with your room's wall color. I like the neater square pattern. For your son's room, I prefer the big squared pattern on the left or the same pattern I like for your room. The round pattern just looks odd to me. Which one does your son like best?

The MS vanity is very cottage in feeling, so I think if you are wanting a more contemporary look I would not go with the matching mirror. Of the other three you have posted, my preference would be #3. I like the finish, and the thinner frame with the intersecting pieces picks up on the narrow strips of the beadboard in the vanity. The first one feels very traditional to me, and I just don't care for the second one. You might consider finding something more oval or round, just to balance all the very strong angles you will have in the tile and cabinet.
