For the upstairs bathroom we have settled on the floor tile, wall tile, vanity, bath fixture, shower curtain, and vanity lights. The other furniture is notional, though we are keeping with the spa-like theme so far.
So far, the budget is pretty low and I think the look is good. We discussed how much of the vanity wall to tile, and I think we are going with the middle option below. We think this option will create the look we're going for without tiling all the walls around my huge bathroom (6'x14'). That would be too much labor, and a bit too retro.
Since the vanity doesn't arrive until mid-July, there is a while before the bathroom is done. Stay tuned as I stumble through tile work!
