Threnee-A few thoughts. First, Doug is right about Robern. Their cabinets are beautiful although expensive. I was thinking about buying the new Uplift cabinet, which opens straight up like a garage door. It avoids you having to step away to open the door. You could hang pendant lights in front of it--that's how they show it in the catalog. I ultimately decided not to buy the cabinets--I needed two and the scale didn't work anymore with my room. We decided to go with towers on either side, which I had before and I much prefer. We are putting the lights on the side of the tower. So you could try that. Finally, you might think about putting a tall, shallow closet on the back wall and either mirroring the door or using plantation shutter doors--I happen to love that look. A shallow closet would hold all the little stuff. I came to the conclusion that medicine cabinets are expensive and provide much less optionality that other solutions. HTH

If/when we gut our master bath, this is exactly what we will do with newly de-tiled wallspace inside the door (backing into closet in bedroom). However, our set-up will be deeper (made from 11"x1" boards), and open (baskets on shelves). I hope to recess the existing (utilitarian, from Lowes) medicine cabinet into the wall opposite the sink, and place a large framed mirror on the wall above the sink. This way, we're maximizing all the available wall space. Can't wait!

Do some searches for the largest sink that fits inside a 24" cabinet, not a 23" cabinet. What you have is actually called a 24" cabinet. There are a bunch of relevant threads when you do that: https://www.houzz.com/discussions/i-need-the-biggest-sink-possible-for-a-24-in-kitchen-sink-base-dsvw-vd~899678 http://ths.gardenweb.com/discussions/2477916/sink-to-fit-24-inch-cabinet http://ths.gardenweb.com/discussions/2703149/whats-the-biggest-sink-that-can-fit-into-ikea-cabinet (This is discussion about cabinet modifications to fit a bigger sink.) http://ths.gardenweb.com/discussions/2531082/what-single-bowl-stainless-sink-to-fit-24-base-cabinet Several of the posters in those threads mention specific sink models that they used.

you'd have much bigger problems with an overhead light when you opened your cabinet!!! I'd see whether (a) the cabinet can be fully or partially recessed, which will also give you more visual space. otherwise, (b) just get sconces that stand out from the wall enough to get past the cabinets. You might find that most wall sconces already do that -- even if it's partially blocked, most of the light will be coming forward and probably still be ok.
