Place these liners on top of an old or damaged floor sink. Made of 304 stainless steel, they’re durable and resist corrosion from liquids draining through. Their smooth surface also makes them easy to clean. A rubber gasket seals these liners to the existing drain and secures it in place. The grate prevents large debris from entering the liner. For another level of protection, a dome strainer sits at the bottom of these liners to stop small debris from entering the plumbing system.
