Bathroom redecorating

When I finally get around to re-doing my bathroom, I think I'm going to check out this link for discount Grohe faucets. I can't decide what I want to do with the sink area of the room. I know what I want to do with the shower/bathtub and I have some ideas for the toilet area. The sink, however, has me completely stumped. I know we need more storage area but I'm not sure where we'd be able to put it. Maybe I can expand the medicine cabinet a bit. That would be nice, I think.
