The M1022GF Colored Glass Undermount Sink is created of fully tempered glass, which means it can withstand higher temperatures without incurring damage. Because it is non-porous, glass is also one of the most sanitary materials available in sink designs. This glass model provides the beauty of glass, usually seen only in vessel sinks, in an under-the-counter installation. Undermounting a bathroom sink creates a sleek look and allows for more space on your countertop. A frosted surface gives this model a soft appearance. The overall dimensions of the M1022GF are 19 7/8" x 17" x 6 1/2" and requires a 21" minimum cabinet width. Grid drains in a variety of finishes are available with this sink model, and as always, our glass sinks are covered under a limited lifetime warranty for as long as you own the sink.
