Bagna càuda means "hot sauce". Bagna is the Italian word used for sauce or gravy. And càuda means "hot" in the Piedmontese dialect. However bagna càuda is often translated as meaning a "hot bath". This is incorrect. Bath in Italian is "bagno" but "bagna" which ends in an 'a' means something completely different. Yes, it does make a difference which vowel the word ends in!
