A better and more international English term would be to call it a Glamour Wardrobe. The use of commode as a chest holding a chamber pot actually originates in England with washstands. It then extended to the commode chair. Finally in the US it went from being used for commode chairs/wooden toilets to a euphemism for the flush toilet. To paraphrase an old George Bernard Shaw saying about the English language, "A group of peoples separated by a common language."
