18 Inch Fireclay Drop-In Prep Sink

The round SN1818R measures Ø18½" (470 mm) across the rim; the square SN1818S is 18" × 18" (457 mm). Both share a 9" (228 mm) overall height with a 7⅞" (199 mm) interior bowl depth, a single bowl, and a centered 3½" (90 mm) drain opening.

It's sized for secondary prep stations — kitchen islands, butler's pantries, wet bars, and outdoor kitchens — where a full sink won't fit. The compact 18" footprint adds a dedicated spot for rinsing produce, prepping drinks, or washing hands away from the main basin, keeping the primary sink free during entertaining.

Choose the SN1818R (round) for a softer, classic bar-sink profile with no inner corners to wipe around. Choose the SN1818S (square) for more usable basin area and a cleaner line against rectangular cabinetry and countertop edges. Both share the same 9" height, 7⅞" bowl depth, and centered 3½" drain.

It installs as a top-mount drop-in into a countertop cutout, with the 1½" (38 mm) rim resting on the surface. No pre-drilled faucet hole — mount the tap on the deck or wall behind it. Follow the spec-sheet cutout template; the 3½" (90 mm) drain fits standard strainers and disposal flanges.

The minimum order is 50 pieces, with a 30–45 day production lead time. Both bowl shapes come in glossy white or matte black fireclay, and custom sizes are available on request. Quotes ship FOB or CIF, with an engineer reply within 24 hours.

Fireclay is kiln-fired into a dense, non-porous surface that resists stains and heat, won't rust, and won't show water spots like stainless. Its glazed finish wipes clean easily and comes in glossy white or matte black — a look most composite and stainless sinks can't match. The solid body also runs quieter.
