That's not a shower, that's a bath, which is good, because in some lore, vampires are affected by fresh running water, like rivers, and probably sinks, and showers. Really depends on how it's defined, but it's always at least universally agreed that baths are fine.
Vampires have more weaknesses than they can count on their hands. If you’re a vampire and step on a wooden lego, open a window in daytime, touch garlic, or exist i the rain, you die.
