There's nothing quite like taking a quiet, relaxing bath by candlelight, but if for some reason you can't have all that candlelight around, you can try these cool Spa Lights that will stick to any surface by suction. Not quite the same as true candlelight, but Spa Lights give off a soft glow and even float in the bath water. You can't do that with candles (well I guess you can, but I wouldn't try it in the bath).
