Start with a favorite item that will be in your bathroom--picture, towel, shower curtain, accessory, etc., and then go to a paint store and get a bunch of free color swatches that match/coordinate with the color(s) in your item. Take them home and tape them up in your bathroom and see which color "fits" the space the best. Paint the space that color, and then buy accessories to match--a shower curtain is a good starting point as it will be the largest visible items in the room.
Take your paint swatches and small hand towel with you when you shop for coordinating accessories to help you "mix and match" with ease. And build "the look" slowly--piece by piece, rather than buy everything in one shopping trip.
