I know that Dal still makes cove base, and will make them in most of their colors as a special order. I'm sure that Florida still makes them too. Crossville makes cove base for their quarry tile and might make that trim for porcelains and ceramics also?
No really special prep needed, though the void caused by the arc of the cove base should be back-buttered to give it support.
