This classic Kohler Mid-Century bathroom sink has angled corners and looks like it was designed for tighter spaces. It is an 18-inch x 20-inch model, and has a date stamp of July, 1964. This ultra heavy duty commercial grade cast iron sink has a "glass-like vitreous china" finish and appears to be a Kohler "Chesapeake" model ledge lavatory. However, this one has clean smoothed edges as opposed to a raised border wrapping around the front of the Chesapeake. This particular Kohler wall sink is a "leg support model", requiring two bathroom sink leg supports under the front end for proper and safe installation. Leg support sinks can be identified by a lack of a rear back panel and mounting holes, and there should be two small tabs molded into the cast iron underneath the sink to hold the leg mounts. We found this sink stuck in the mud in the woods outside a residence. It had been there for decades. The exterior was cleaned with simple Comet cleanser, and there were only a couple of small rusty orange spots that need extra attention. Much of the flaky and pitted rust underneath has been removed with elbow grease and a bag of steel wool pads. There is one noticeable chip in the upper right top corner and one very small chip in the lower left bottom edge, as well as some minor scuffing and haziness around the lower back of the bowl area from years of normal use and cleaning.
It actually cleaned up quite nicely (especially considering its age and poor storage) and only requires minor restoration before its ready for use again. Considering the unbelievably rugged quality and craftsmanship shown in this model, I would safely assume that most antique and vintage Kohler sinks can be restored and are still completely useable. Mid-century bathroom sinks really add that authentic touch to your lavatory decor.
