Hiya sheesh, can't believe I missed this posting! It looks really nice, great job. I've been working on our upstairs hall bath and I am just doing a couple of tweeks before the "reveal". Have you looked for pretty soaps at TJMaxx? I am now totally hooked on them. They even organize them by color! I've been buying them to put in glass jars in the bathrooms. They are wrapped in gorgeous papers, and as long as you have some sort of common color, they all look great mixed together. You could also consider a bowl with some natural sea sponges, that would look pretty too. Glass jar filled with cotton balls looks kind of fun too. Great job! -bee

That looks like a really terrible location for lighting given the light-blocking frame around the mirror. I would replace it with a small, better-looking fixture, and get an electrician to run power to each side of the mirror so you can have sconces that are set off from the wall and give you decent side lighting.

If you center the mirror over the sink, there will be 15" on one side, and 15" on the other. 3" left plus your 1 1/2" spacer gives you 4 1/2". You're right, you don't want it right up against the corner, so a less wide mirror is better. Alternatively, you could mirror the full wall under the window, and do cut-outs for the lights. Like this:

Build.com lets you search and sort by width, # of bulbs and a bunch of other criteria. I just did a quick search for 3 bulb vanity lights between 15-20 wide. ***Re: blinding light. I chose a light fixture that's dimmer compatible, and put in dimmable LED bulbs and a dimmer switch. It's my guest bathroom - guests getting up in the middle of the night to use the bathroom will appreciate the dimming capability.*** On build.com, and some other sites, you can then compare up to four at a time:
