Under the Sea Collection
Under the Sea is a mother of pearl mosaic tile collection inspired by the coastal waters of Southwest Florida. We are a family business rooted in Naples — where the Gulf is warm, the light changes everything, and the water has a way of making even the most ordinary surface shimmer. That quality is what this collection is built to bring indoors. Every piece pairs genuine shell and nacre with brilliant white Thassos marble, creating an iridescent, organic surface that catches the light differently at every hour of the day.
The Under the Sea collection includes seven mother of pearl mosaic tile designs in white, natural, rose gold, and silver colorways across free-form, chevron, herringbone, and brick patterns. The free-form designs move across the surface the way water does — in fluid, sinuous strands that never repeat exactly. The herringbone and chevron patterns give the iridescent shell a structured geometry that balances its organic shimmer. The brick patterns are the most understated of the collection — steady and rhythmic, the kind of surface that rewards close attention.
Every piece is polished to bring out the full depth of the shell. Suited for kitchen backsplashes, bathroom walls, vanity walls, shower walls, accent walls, and room floors. Mother of pearl is not recommended for shower floors. Samples available before you commit.
The Under the Sea collection was inspired by the coastal waters of Southwest Florida. The Mosaic Shop is a family business rooted in Naples, FL, where the Gulf of Mexico light plays across the water in a way that makes every surface iridescent. The organic, flowing quality of mother of pearl captures that same shifting, luminous quality and brings it into the interior spaces where we spend our lives. It is a collection built around the idea that natural materials, when chosen well, carry the feeling of a place with them.
The difference is in the tone of the mother of pearl shell. White mother of pearl has a bright, cool iridescence that pairs with the brilliant white of Thassos marble for a crisp, luminous result. Natural mother of pearl has a warmer, honey and amber shimmer that gives the mosaic a softer, more organic quality. Both are genuine shell, both are polished, and both pair with white Thassos marble. The choice comes down to whether your space calls for a cooler, brighter palette or a warmer, more understated one.
The Under the Sea collection is suited for shower walls but not shower floors. Mother of pearl has a polished shell surface that is not recommended for floor applications where slip resistance is a priority. We recommend sealing mother of pearl before and after installation with a premium impregnating sealer formulated for natural stone. Regular cleaning with a pH-neutral cleaner will maintain its natural luster over time.
