MTI Baths’ integrated counter sinks connect one fixture to another in a seamless look and are compatible with most manufacturers’ vanities. The integrated sink’s length, width, deck height and bowl placement can be customized to any specification with custom colors and designs. The sinks are constructed of proprietary Engineered Solid Stone, a mixture of natural ground minerals and high-performance resins that are liquefied, poured and then hardened. The result is what looks and feels like molded stone. ESS is 100% solid, with no hollow spots, voids or surface coating. About 65% of the material is organic and utilizes a resin of combined renewable bio-derived and/or recycled content.
