Straightforward and elegant, MTI Whirlpools’ Metro collection of sinks and tubs offers minimalism in the bath. The sink’s geometric form mimics the tub’s lines and is crafted from MTI’s Engineered Solid-Surface material, which is a mixture of ground natural minerals and binding agents that are liquefied, poured and then hardened. Available in two sizes, the nonporous units are stain-, mold- and mildew-resistant.
