Trimscape GCL112-series drains are designed specifically for install with wall-mount cast iron utility sinks in bathrooms. A beautiful industrial-influenced or rustic farmhouse styled bathroom deserves coordinated details and proper finishing touches. These drains are designed to offer a finish-matched push pop-up lavatory drain solution for installing a wall-mount cast iron utility sink in a bathroom. The drain tail fits into a 1-1/2" P-Trap, commonly associated with Kitchen sink drains. Kingston also offers a line of finish-matched 1-1/2" to 1-1/4" P-Traps for retrofit install with a bathroom drain connection as well as stepdown drain tails that allow connection from a 1-1/2" drain tail to a 1-1/4" P-Trap, if you have a matching 1-1/4" P-Trap already.
