With a variety of helpful features, the Tyrrell service sink is a highly functional addition to any workspace. Its large basin allows the placement of more volume, and siphon jets in the rim provide a uniform cascade of water to effectively eliminate maximum debris or waste and keep the sides of the basin clean. Crafted of durable vitreous china, this sink features a 1-1/2" top spud and a 2-1/2" trapway - larger than most residential toilet trapways.
