This is based on a discussion in the TRS, to make Candlelit Bath into Exactly What It Says on the Tin and create a new trope for when a bath turns fatal (candlelit or not). I added the Interrupted Bath YKTTW over here. Taking a bath is risky business, at least in entertainment media. Nine times out of ten, either something happens to interrupt the bath, or you die. This is the latter. In part, this is due to the Law of Conservation of Detail. The only reason to show somebody doing something as mundane as bathing is because something narratively important is going to happen during that bath -- unless it's just for Fanservice. And it isn't hard to see why the bathtub or shower would be such a common place for murderers to show up. Bathing is when you're at your most vulnerable; relaxed, alone, naked, possibly with water in your eyes, in a small room that usually has one door and no windows. Or, alternatively, it's a Bath Suicide; a time that should be relaxing and pleasant becomes suddenly awful. Whether murder or suicide, there may be an Electrified Bathtub involved. The "Psycho" Shower Murder Parody is a particularly common example of this trope -- or a subversion, depending on the humor content. A Deadly Bath will very commonly lead directly to Blood Is Squicker in Water, and may turn into a Blood Bath. A Candlelit Bath can easily turn into one of these when it isn't turning to romance. Subtrope of the Bathtub Scene or Shower Scene, and the Interrupted Bath.
