From glitter grout to oil slick decor, there are many unconventional home trends popping up these days — but only one is taking over our Pinterest boards: mermaid tiles. Previously seen in coastal homes, these scale-like tiles have hit the mainstream, and Pinterest is reporting that interest in mermaid scales is up 100 percent year over year. The name might evoke images of slimy fish under the sea, but contemporary iterations are subtle, understated, and simply breathtaking, such as iridescent backsplash and whimsical textured flooring. And if you're looking for something less permanent than tile, consider incorporating the trend in the form of an art print, throw pillow, or tiled picture frame. Check out a few of our favorite mermaid tile examples to get your trend fix ahead.
