The M86SS is chiseled into a beautiful basin from a large block of natural sandstone. It takes shape as a very thick circular bowl with a sense of roundness throughout. Delicate beige and cream tones swirl throughout the basin creating an intriguing visual display. Both the interior and exterior are gently sanded to a smooth, very matte yet hard-wearing finish. Overall the sink rises to a 5 1/4" height and measures 15 1/2" x 15 1/2" with a 2" thickness. Its inner depth is 3 3/4" with a centerset drain. A variety of vessel faucets are available for use with this sink. As always, our stone sinks are covered under our limited lifetime warranty for as long as you own the sink.
