Introduction

When you’re decorating your home for Halloween, every room deserves a bit of festive flair — even the bathroom. A fun, well-executed theme can make the space memorable and a delightful surprise for your guests. In this article, we’ll explore 21 funny Halloween bathroom ideas you can try. These ideas are easy to implement, affordable, and full of personality. Let’s dive in.

Why decorate the bathroom for Halloween?

It might seem odd to focus on the bathroom when you’re prepping for Halloween, but there are good reasons:

• The bathroom is often overlooked, so decorating it makes your entire home theme feel immersive.
• Guests will use this space — adding a quirky touch here makes it memorable.
• With simple decor changes, you can dramatically transform the mood — and humour helps lighten the spooky tone.
• Some home-decor experts suggest that minor tweaks like fake cobwebs, themed towels, and coloured lighting go a long way. royalbathrooms.co.uk+2Home Decor Full+20

So yes — it’s worth investing a little time into your bathroom to create a unique Halloween setup. Below are 21 ideas you can pick and choose from depending on your space, budget, and sense of humour.

1. Spider-web Shower Curtain

Start with something simple: swap your regular shower curtain for a black or dark coloured one printed with spider-webs. The webbed pattern instantly delivers Halloween flavour without being heavy.
Tip: Add a few plastic spiders to cling to the mesh or edges — inexpensive but effective.

2. Bloody Handprint Mirror Decals

Turn your mirror into a scene of playful spookiness. Get removable decals or stickers shaped like red handprints and stick them on the edges of your mirror. It gives a “someone’s been here” surprise effect.
Tip: Use darker red or burgundy tones so the effect is dramatic, not cartoon-ish.

3. Jack-o’-Lantern Toilet Seat Cover

Make your toilet the star of the show with a jack-o’-lantern themed seat cover. The grin of a pumpkin face — just when someone lifts the lid — adds unexpected humour.
Tip: Match it with a pumpkin motif bath mat so the theme carries through.

4. Skeleton Bathroom Set

Instead of just towels, consider a full skeleton themed set: soap dispenser shaped like a skull, toothbrush holder shaped like bones, tissue box cover that looks like ribs. It’s playful, spooky, and unified.
Tip: Choose white skeleton pieces so they pop against darker backgrounds.

5. Witch’s Legs Toilet Plunger

This one is quirky and funny: glue or attach striped witch’s legs (think green and black tights) and pointy shoes to a plunging tool near the toilet. It looks like the witch took a dive and ended up there.
Tip: Use secure adhesive and waterproof materials — bathrooms are wet spaces.

6. Ghostly Toilet Paper Roll Eyes

On the roll of toilet paper, stick two round black “eye” shapes so it looks like a ghost or creature is peeking out. It’s a small detail, but it gives a wink of humour.
Tip: Use glow-in-the-dark stickers for extra fun when the lights are low.

7. Bat Wall Decals

Apply bat-shaped decals flying across the walls above sinks or near the ceiling. The movement effect is humorous in an unexpected space, like a bathroom.
Tip: Use varied sizes and angles so it looks like a fluttering swarm, not just static shapes.

8. Halloween Themed Bath Mats

Swap out your ordinary bath mat for one with Halloween icons—ghosts, pumpkins, skeletons. It’s an easy switch, adds colour and theme underfoot.
Tip: Choose a non-slip mat to keep safety a priority even while decorating.

9. Glowing Potion Bottles

Place clear glass bottles on a shelf labelled with funny names like “Witch’s Brew,” “Spider Venom,” “Ghoul’s Elixir,” filled with coloured water and maybe add LED tea-lights for a glow effect.
Tip: Secure bottles so they don’t fall if the shelf is bumped.

10. Creepy Shower Decals

Stick silhouette decals on the inside of your shower door or on the curtain — e.g., hands reaching, ghostly figures, or a dripping effect. When someone takes a shower, it becomes a moment of surprise.
Tip: Use decals that are waterproof and designed for bathrooms.

11. Floating Candles Over the Tub

Hang battery-operated LED candles from the ceiling (using clear fishing line) at varying heights above the bathtub or around the mirror. It gives a whimsical “floating candle” effect, reminiscent of a magic movie.
Tip: Make sure they’re far enough from water spray and check battery safety.

12. Pumpkin Tissue Box and Toilet Paper Holder

Use a hollowed pumpkin (or pumpkin-shaped craft container) as a tissue box cover or toilet paper holder. It’s seasonal, functional and oversized in a fun way.
Tip: Choose a small pumpkin or faux-pumpkin to fit safely without blocking anything.

13. Spooky Silhouette Window Clings

If your bathroom has a window, apply silhouette clings of witches, cats, and haunted houses. Backlighting at dusk gives a fun exterior view and adds to the interior mood.
Tip: Use removable clings so you can easily take them off post-holiday without damage.

14. Halloween Themed Soap Dispenser

Swap in a soap dispenser shaped like a ghost, pumpkin, or skeleton. A small change, big impact. Every time someone washes their hands, they’ll get a smile.
Tip: Fill with coloured soap (orange, green) to carry the theme further.

15. Cobweb Corner Decorations

Stretch fake cotton-web material across a corner of your bathroom ceiling, around a light fixture or near the sink, add small plastic spiders — this creates texture and fun creepiness. royalbathrooms.co.uk+1
Tip: Use a minimal amount to avoid making the space look dirty or cluttered.

16. Eerie Artwork on Walls

Frame some funny Halloween art for the bathroom wall: a skeleton reading a newspaper on the toilet, a ghost sipping tea, etc. It brings humour and whimsy.
Tip: Choose moisture-resistant frames or laminate the prints if your bathroom is steamy.

17. Glowing Eyes in the Medicine Cabinet

Place a couple of glow-in-the-dark stickers shaped like eyes inside the medicine cabinet when the cabinet appears haunted in a gentle, humorous way.
Tip: Ensure the stickers are safe for plastic surfaces and won’t leave residue.

18. Witch’s Brew Bubble Bath Display

Create a small display by the bathtub with a cauldron (or cauldron-shaped dish) labelled “Witch’s Brew” filled with coloured bath bombs or bubble bath packets. It mixes decor with a usable product.
Tip: Choose a non-messy bubble bath so it’s still functional and safe.

19. Funny Guest Bathroom Sign

Hang a humorous sign by the bathroom door, e.g., “Beware: Ghosts use this loo at midnight” or “Witch Parking Only.” It sets the tone before someone even enters.
Tip: Use waterproof sign materials so they survive steam and moisture.

20. Toilet Seat Sticker Surprise

Use a humorous sticker under the toilet seat lid – perhaps a ghost face, surprised eyes, or “Don’t spook me” text. When someone lifts the lid, they get a fun surprise.
Tip: Make sure the sticker is removable and won’t stain or leave sticky residue.

21. Black-Light Bathroom Party

If you really want a fun twist, install a cheap black-light strip or bulb and use neon Halloween decorations (neon spiders, skeletons, towels) that glow in the dark. The bathroom becomes a party spot in miniature.
Tip: Ensure electrical installation is safe for wet areas and is placed away from splashing water.

Pulling It All Together

• Pick a theme direction: humour + spooky works best when there’s a slight balance—too scary and it may feel heavy; too silly and it might feel out of place.
• Stick to a colour palette: Using 2-3 colours (e.g., black, orange, white) keeps the design cohesive. Experts point this out as key to effective DIY holiday decor. royalbathrooms.co.uk+1
• Use functional items: Try integrating decor into items you already use (towels, mats, soap dispensers) so it feels natural and not cluttered.
  
• Safety first: In bathrooms, you’ll have moisture, slippery floors, and perhaps electrical items (lights). Make sure any decor is water-safe, non-slip and electrical work is suitable for bathrooms.
• Keep it easy to remove: After Halloween, you’ll likely want to revert back. Use removable decals, temporary pieces, and items you can easily swap or store.
• Add small surprises: Often it’s the little detail (glow-in-the-dark eyes, funny sign, witch’s legs) that guests remember more than a full dramatic transformation.
