At first, I thought she was joking — but two fog machines, some green LED lights, and a bathtub full of dry ice later, it became one of my favorite small-space projects ever. That’s when I realized: small bathrooms have enormous potential for big Halloween drama.1. Creepy Candlelight GlowDimming the lights and adding flickering LED candles creates instant atmosphere without the fire hazard. The challenge? Hiding the candle bases so the magic stays believable.save pin2. Glow-in-the-Dark DecalsFrom bats to ghost silhouettes, these stick-ons surprise guests when the lights go out.

Nothing unsettles guests like unexpected whispers in a small space.save pin9. Black Lace Shower CurtainIt diffuses light and creates layers of shadow — perfect for that haunted mansion vibe. You may need an extra liner to keep water from escaping.save pin10. Floating Hands from the CeilingLightweight props hanging by fishing line are surprisingly effective in a confined space.
