Want something with interest that also makes sense in this room.

- If you want something that'll blend in /create a calm, simple room, go with a light-wood or greige-tan-painted vanity.

- If you want something that'll stand out /be a star, I'd go with a deep blue.

Thinking of a single offset sink.

- I'd keep the sink on the small side and consider a wall-mounted faucet (makes for easy cleaning).

- Definitely go with an offset sink so you can have a good-sized set of drawers on one side /you don't want two too-skinny drawers, as the sides and hardware will eat up so much of your modest width. Be sure the doors go all the way to the back (cheaper drawers, even in custom, can stop several inches short of the back -- what a waste!

- I don't see any other storage in this bathroom, so I'd consider an open shelf on the bottom for towel storage.

- I'd finish this vanity with a fairly large mirror (to make this modest-sized room look larger) flanked by two pendant lights.

Other thoughts:

- I'd also consider a shelf above the toilet for storage.

- Where will you hang towels? Looks like your shower door is hinged the wrong way for easy-reach towels.
