The Shagreen collection celebrates the subtle coloring and distinctive pebbled texture of natural shark and ray leather. Inspired by oil spot glazes that originated in China during the Song Dynasty, a two-step glaze process uses minerals to create an interplay of shimmery and matte effects. A striking complement to the oval KOHLER Caxton sink, the rich glazed finish shows iridescent pearly tones and a gently granulated texture similar to leather. Each oval undermount bathroom sink’s pattern, formed through an organic process, is unique.
