This is a comment on a post that does not (as of yet, or does not) accept comments outside of the forum. The bathroom is awesome, a great redo. Were I you, I would consider painting the window frame black, and to try to source some matching black tiles to frame around the mirror where it meets the wall. But then, I really like black.
Again such a great job, perfect wallpaper and towels. I may add a few wooden details to time in the wood on the front of the cabinet - maybe a wood or wicker laundry basket, or a … many possibilities.
