Each KOHLER® WasteLab® Vox® bathroom sink is individually handcrafted by artisans in Kohler, Wisconsin, making every piece truly one-of-a-kind. The innovative process introduces subtle variations in shape and surface, celebrating the human touch behind each sink. Defined by their unique material origins, Vox® sinks are available in two unique finishes — Ashen, using repurposed vitreous cull blended with cast iron foundry dust producing a smoky gray tone for depth, texture, and industrial character, and Eggshell, combining reclaimed vitreous cull with reprocessed Vikrell® material which yields a matte-white finish with a clean, modern feel. A testament to our commitment to craftsmanship and circular design, Kohler transforms industrial byproducts into functional works of art.
