I like this mirror for a bathroom

There's not much room for a centered mirror over the sink. I'd be tempted in this space to just put in a frameless mirror that fills the entire back wall. Get a hole cut out for the outlet, and a mirrored outlet cover. You could even put a narrow shelf right above the tile with a full mirror above. That might help with the lack of counter space.

Your tiler did a nice job getting that tile centered right on the faucet.

What is the paint color on the wall? It looks nice with the tile.
