The M87GBM is chiseled from a large block of natural marble. Presenting an ironically elegant, yet rustic, appearance; it is a beautiful example of natural simplicity. The smooth rim follows an irregular up-and-down course as it circles the bowl, while the rough-hewn exterior bulges and recesses. The interior is highly-polished with a centerset drain. Overall the sink takes on an irregular rectangular shape rising to a 6 1/2" height and measuring 19 1/2" x 14 1/4" with a 1" thickness. Its inner depth is 4 3/8". A matching stone waterfall faucet is available to correspond with this sink. As always, our stone sinks are covered under our limited lifetime warranty.
