At EOS Surfaces, we strive to provide high-quality solid surface materials with consistent color options. However, it is important to note that product samples are intended for general color matching purposes only and may not represent an exact match to the final product received. Due to the nature of our proprietary material and manufacturing, we cannot guarantee exact color matches between different production lots. Even within a single large lot, slight color variations may occur from the beginning to the end of the pour. These subtle shifts are a natural outcome of the production process and add to the uniqueness of each piece. To assist our certified fabricators in ensuring the best color consistency, each sink and slab is labeled with a lot number and a mold number. These identifiers allow you to partner pieces, arranging them chronologically (in order of pour). Doing so will optimize color matching during fabrication. We recommend following these guidelines to achieve the most uniform appearance in your finished projects.
