We have a powder room that was created by previous occupants by making use of the space under a staircase. The dimensions are a little odd, it's very tiny with a sloping ceiling, and everything is a bit off center--the toilet is not centered on a wall and the sink does not align with the window it's under. I wanted an asymmetrical mirror because I didn't want to further call attention to things not lining up. We hung this mirror with the longest side horizontally and it looks great. This does not come with hardware to hang it, so I strongly recommend you get some 50 - 75lb EZ Ancors so that you can hang this safely.
