Nativestone® Malibu Round Bar & Prep Sink. Malibu lives up to its iconic name – this stylish and versatile concrete sink creates a stir, indoors or out. This bar sink's wonderfully functional, deep, circular shape is perfect for chilling beverages. And talk about versatile! Install as a drop-in sink to show off the smooth concrete rim, or install as an undermount sink for a look that's more discreet, but just as elegant. ** Due to their handcrafted nature, no two products will be exactly the same and may vary in finish, texture and other details. **
