This is just an iPhone photo of a powder room at #ExhaleCI, but I wanted to point out the alignment of the mirror and the hung art print--they were intentionally hung at the same height to create a natural transition as our eye sweeps across the space. We chose to ignore the height of the window in terms of alignment, because hello, it's way too high!
Basic rules for hanging things on bathroom walls:
1-Aim for eye level (eye level of the space's primary users)
2-Look for common alignments in other hung or vertical objects
3-Use common sense.
