Oxford Grey is a lovely dove gray that will instantly add history to your home. This beautiful antique cotta design was developed from reclaimed French cotta, which is faded and more neural in color than the bold Spanish adobe cotta we often think of.  Oxford Grey tiles are sized 18” x 24” with shale-colored InteGrout™ that will not stain. Korlok Select interlocking stone tiles are equipped with waterproof K-Core® technology for a floating installation over most existing hard floors.
