Bathrooms are often the most overlooked space when decorating for Halloween, but transforming this small area can leave a big impression on your guests. A ghostly Halloween bathroom theme creates unexpected thrills, turning an ordinary room into a haunted hideaway. With just a few creative touches, you can make your bathroom feel like part of the haunted house.

Start with eerie lighting. Swap out standard bulbs for dim red or flickering LED candles to give the space a spooky glow. You can even drape sheer white fabric over a light fixture to create a ghostly effect. Glow-in-the-dark decals on mirrors and walls also add a haunting surprise when the lights go out.
For a true ghostly vibe, use plenty of white and translucent décor. Hang gauzy cheesecloth or sheer curtains from the ceiling to mimic floating spirits. Place small ghost figurines on shelves, or stick vinyl decals of eerie faces on mirrors for jump scares. A fog machine hidden near the floor can add an extra layer of mystery as guests step inside.
The sink and toilet area are perfect places for creepy details. Place bloody handprint stickers on the mirror or add fake cobwebs stretched across corners. Swap your hand towels for ghost-themed ones or fold white towels into ghost shapes for a playful yet spooky touch. A bowl of candy by the sink adds both hospitality and a festive detail.
Don’t forget the finishing touches that bring the ghostly bathroom to life. Motion-activated sound machines with spooky whispers or ghostly laughter are perfect for startling guests. Scented candles with musky or smoky fragrances can enhance the eerie ambiance. With these simple but creative ideas, your bathroom can be just as haunting as the rest of your Halloween décor, surprising guests in the most unexpected place.

Nice ideas — the bathroom details are surprisingly effective. Quick question: any tips for making the fog machine safe in a small, humid room? Also, do glow-in-the-dark decals lose their brightness after one season?
