Decorated from top to bottom in kitschy mermaid and ocean-themed décor, this might just be the most fun you'll ever have peeing (or whatever else). Vintage pink fish chalkware, stained-glass panels of Ariel herself, handcrafted goods with glued-on sparkly stones, and, for some reason, a framed cut-and-paste homage to Audrey Hepburn. Even the toilet seat is hand-painted with seashells. Totally ridiculous—in the best way.
