Part of MTI's Boutique Collection, the Elise lavatory sink is constructed using MTI's "ESS" (Engineered Solid-Surface) composite material, which is a mixture of ground natural minerals and binding agents that are liquefied, poured and then hardened. Think of molded stone. Non-porous, stain-resistant, mold and mildew-resistant. The Elise LV lavatory sink measures 22.25" x 14" x 5.25" deep.
