Under-mount Sink
The under-mount sink is clean looking sink found most often newer construction and remodels. They cannot be installed into plastic laminate or tile counter tops. They can only be installed into solid surface counters such as stone or synthetic composite tops such as Corian® or Silestone®.
As the name suggests, these sinks mount from the underside of the counter. They are slightly larger than the opening of the top, with the top creating a slight lip or overhang into the sink bowl. The bathroom sink itself is typically made from porcelain enameled cast iron, vitreous china, metal like copper or stainless steel, or out of a a composite resin material. If the sink and the top are composite resin then the sink can be manufactured integral with the top (like the "cultured marble" tops of old). Plumbing waste and supply lines are concealed in the vanity base.
