The P468 golden silk onyx vessel sink is chiseled into a beautiful basin from a large block of natural onyx, a type of marble. This sink is colored in swirling patterns of burnt umber, sepia, and tan. The basin features a split-level interior. The main bowl is offset to the right and measures 16 3/8" x 11.5" x 3 3/8". The shallow ledge on the left provides a place to set water-resistant utensils. Overall the sink rises to a 4 7/8" height and measures 22" x 16". The bottom is flat with a drain centerset within the large basin. Along the back is a pre-drilled hole for a single-handle or matching waterfall-style faucet. The entire sink rests solidly on the vanity as a thick, widespread slab of amber onyx, seemingly just hewn from the mountain-side. Its rough unfinished exterior sides stand in sharp contrast to its smooth, highly-polished top and interior. As always, our stone sinks are covered under our limited lifetime warranty.
