I don't know about all french kings, but at least one went to the toilet surrounded by his 'fanclub'çause he was so proud of owning a toilet that he wanted to show off. At least according to Discovery channel.

Since the situation (being watched at toilet) had been the case with virtually every king important enough to be known to history (that is, for thousands of years), I hardly think a King of France would have made such special note of it.

On the other hand, he might well have gotten a new one, and that fact, not the toilet, might have been worth noting.
