A coastal laundry sink pairs a white oak vanity with a speckled light-gray granite top and an undermount basin, anchored by an aged-brass widespread faucet. Sea-glass scallop tiles form a shimmering backsplash beneath a porthole-style round mirror. White plantation shutters wash the space in sun, casting soft shadows across abalone shell knobs. Navy-and-white towels and a glass jar of shells layer texture and nautical cues for a bright, breezy feel.
