Standard Features and Construction of Engineered Solid Stone Sinks


MTI’s SculptureStone® material is non-porous and solid throughout. Competitors’ composite material has a top-surface coating applied.

  • MTI solid stone sinks are constructed using MTI’s SculptureStone material.
  • SculptureStone material is Engineered Solid Stone, a mixture of ground natural minerals and binding agents that are liquefied, poured and then hardened.
  • The result is molded stone.
  • Approximately 70% of the material is organic, including minerals mined from the earth, making it quite “Green”.
  • In contrast to some composite material products on the market, MTI Boutique Collection products are solid through-and-through, with no layers, hollow or void areas, requiring no type of surface coating.
  • This material is non-porous, stain-, mold- and mildew-resistant, making cleaning and maintenance easy.
