Published June 17, 2026 · Reading time: 8 min
The toilet. That tiny room everyone passes through but no one decorates. The result: white walls, a roll of paper, and an awkward silence. What if we changed that? A well-thought-out toilet decor idea can transform the little corner into the most memorable room in your home, the one your guests talk about when they leave (for all the right reasons).
At Les Petites Fesses, we've made toilet decoration our specialty. Humorous posters, quirky illustrations, messages that make you smile: here is the complete guide to decorating your toilet with style, character, and a good dose of wit.

The toilet is the most visited room in the house. Every guest passes through it at least once. And yet, it is often the last room to receive a little attention when it comes to decor. Here are three good reasons to change that:
It's the surprise room. No one expects a carefully decorated toilet. When it happens, the effect is immediate: a smile, a photo sent to friends, "did you see the poster in the toilet?". It's the perfect place to surprise.
It's a small space, so a small budget. No need for 15 frames and panoramic wallpaper. A single well-chosen toilet poster is enough to transform the atmosphere. In A4 or 30x40 cm, that's 30 to 45 euros for a radical change.
It's the playground of humor. In the living room, we play the "good taste" card. In the toilet, we can let loose. That's where quirky humor, puns, and self-deprecation make perfect sense. The toilet is the decor freedom zone of the house.
10 decor ideas for toilets with character
Idea #1 The humorous toilet poster, the classic that always works
It's the number one toilet decor idea for a simple reason: it works. A poster for the toilet with a funny visual or a quirky message instantly transforms the atmosphere. At Les Petites Fesses, our illustrations combine graphic humor, vibrant colors, and a tone that doesn't take itself seriously. The "Typology of little butts"? A classic. "Big Fession"? A must-have. The little corner has never been so entertaining.
Idea #2 The duo of posters in mixed formats
One poster is good. Two posters of different sizes is a composition. Hang a 30x40 cm format at eye level and an A4 offset next to it or above it: you get a mini gallery wall in your toilet. Mix themes, a humor poster with a quote poster to create contrast.
Idea #3 The quote poster for philosophical toilets
Some moments in the toilet are conducive to reflection. You might as well put an inspiring or funny message before your eyes. A poster with a well-thought-out phrase ("One butt after another", "Happy Butts", "Life is beautiful") transforms the toilet into a meditation room. Or not. But it makes you smile, and that's already a lot. Browse our funny quote and message posters to find the phrase that suits you.
Idea #4 Tropical style in the toilet
Who said toilets had to be austere? A toilet poster with tropical colors, palm trees, birds of paradise, lush foliage, transforms the little corner into an oasis. It's the ideal toilet decor idea for windowless rooms: warm colors and plant patterns compensate for the lack of natural light. Discover our tropical posters for this atmosphere.
Idea #5 Black and white for chic toilets
Humor, yes, but with elegance. Our black and white posters add character without overloading a small space. The "Typology of little butts" in black and white works just as well in modern toilets as in a more classic interior. It's the toilet decor for those who want style without compromise.
Idea #6 The sports poster in the toilet
Yoga, surfing, crossfit, cycling: our sports posters twist the codes of sports with Les Petites Fesses humor. "The little butts greeting" (yoga version) or "Crossfit Cross Butts" in the toilet? It's the kind of wink that hits the mark with sporty friends.
Idea #7 The themed wall gallery
Do you have a little more wall space available? Create a mini gallery of 3-4 posters on the same theme. For example: three humor posters in A4 aligned horizontally, or a mix of formats in a staircase. It's the most impressive and easiest toilet decoration to achieve. No need to drill: discover our tips for hanging a poster without making a hole.
Idea #8 The colorful poster to wake up dull toilets
White tiles, beige walls, fluorescent light: standard toilets don't shine for their atmosphere. A colorful poster breaks the monotony in a blink. Turquoise, yellow, orange, pink: bright colors work particularly well in small spaces because they bring energy without cluttering.
💡 A colorful poster changes everything
Our A4 and 30x40 cm posters fit perfectly in toilets, lightweight, resistant to ambient humidity, and available in dozens of colors.

Add your first names, a personal message, or a private wink on a personalized poster. It's the most original toilet decor, no one else will have the same. Also ideal as a housewarming gift (we have a complete guide on housewarming gifts if the subject interests you).
Idea #10 The kitchen poster… in the toilet?
Surprising but effective: some of our kitchen posters humor work incredibly well in the toilet. Culinary puns ("The sugar melts", "The greed") bring an unexpected and quirky touch that creates surprise. Because the best toilet decor ideas are the ones we didn't expect.
What poster format for the toilet?
The size of your toilet determines the ideal format:
- Compact toilet (less than 2 m²): an A4 format (21x29.7 cm) is enough. Small but impactful, especially with a simple frame.
- Standard toilet: 30x40 cm is the ideal format, large enough to be visible without overwhelming the space. It's our best-selling format for toilets.
- Spacious toilet or bathroom: dare the 50x70 cm. The effect is spectacular and transforms the wall into a real focal point.
All our posters are printed on 350 g/m² art paper, resistant to the ambient humidity of the toilet, and can be framed with any standard frame.
Where to hang a poster in the toilet?
Facing yourself, at eye level (seated). It's the classic and most effective position, the poster is in the natural field of vision. It's also the position that maximizes reading time for posters with text or details.
Above the toilet. The space above the tank is often the largest wall available in compact toilets. A 30x40 cm format fits perfectly there.
On the door (inside face). Where we look when entering. Guaranteed surprise effect, especially with a humor poster.
The decor mistakes to avoid in the toilet
Too many posters in too small a space. In a compact toilet, one well-placed poster is better than five frames fighting for attention. Keep space to breathe.
Too dark colors. Toilets often lack light. Favor posters with bright colors or light backgrounds that visually brighten the room.
The generic. Avoid generic "Keep Calm" posters or beach photos bought in bulk. It's the perfect place for a poster with personality, hand-illustrated, original, that looks like nothing else.
Ready to transform your toilet?
The best toilet decor ideas don't cost a fortune and don't require work. A poster, a nail (or sticky tack), and 30 seconds of installation, that's all it takes to go from "functional toilet" to "toilet with character".
And if you want to know how to hang a poster without making a hole, we also have a guide for that.

Frequently asked questions
What decoration to put in the toilet?
Posters are the simplest and most effective solution to decorate a toilet. They don't take up space, adapt to all styles (humor, minimalist, colorful, quote) and are easily changed. At Les Petites Fesses, our toilet posters are hand-illustrated and printed on 350 g/m² art paper resistant to humidity.
What poster format for the toilet?
The 30x40 cm format is the most suitable for standard toilets. For a compact toilet, opt for an A4 (21x29.7 cm). If you have space, the 50x70 cm creates a real focal point. All our formats can be framed with a standard commercial frame.
How to fix a poster in the toilet without drilling?
Use sticky tack, Command adhesive strips, or double-sided adhesive tape. These solutions allow you to hang a poster without damaging the wall or tiles, and reposition it easily. Consult our complete guide on no-drill mounting methods.
How to make your toilet prettier?
Three simple steps: add a colorful or humorous poster to the wall, place a small plant (even artificial) on a shelf, and change the seat or roll holder for a more designer model. The poster alone does 80% of the work, it's what your guests will notice first.
Do posters resist the humidity of the toilet?
Posters printed on thick art paper (350 g/m² at Les Petites Fesses) resist very well the ambient humidity of the toilet, which remains moderate. Just avoid placing them directly above a direct water point. A frame with glass offers additional protection if you wish.
