Deck your bathroom out in Moroccan fish scales. The unusual shape of these Moroccan tiles look pretty much like a mermaid tail. Not into the whole mermaid thing? There are three sizes and several color palettes available, so you can pretty much make any design your heart desires.
Probably would NEVER happen, but have one long piece to replace since/counter now, including this sink. Everything in one piece. And have some sort of beach theme decoration in sink bowl instead of this one, although it is very beautiful
