Part of the Boutique Collection, the Wymara 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 Wymara LV lavatory sink measures 19.875" x 15.875" x 4.625" deep.
