Every Galley Basin is made from one piece of 316L Marine-grade Stainless Steel. A beautiful, custom Angel Finish is applied to every Basin. The Angel Finish was developed to soften the high reflectivity of standard Stainless Steel finishes and for easier maintenance. The finish resists water spots, hides light marks and scratches and is very easy to clean. The finish is also easily renewable back to a perfect factory finish!
