Bathroom remodel

We saw an ad on craigslist for 50 sq.ft. of tile for $10. We went to look at it and the guy had alot more tile that he just gave to us. We have enough to do both bathrooms. Matt started with the Master bath and then he'll do the hall bath next. Speaking of the hall bath... I have a calendar of sealife and I'd like to use them in a creative way to make something cute for the bathroom. Any ideas? I also have a ton of seashells I can use.
This is the before picture of the bathroom. Matt still has to seal the grout for the tile and then I will take and after pic.
