Three years ago, I hung a lithograph in my Parisian bathroom. An abstract nude, warm tones, Hahnemühle paper. Six months later, it was pristine. Since then, I systematically install art in my bathrooms — and frankly, it's become one of the rooms where I find the most visual pleasure. Yet, when I visit apartments or clients contact me to decorate their interiors, the bathroom remains the forgotten space. As if humidity prohibited any aesthetic ambition. Spoiler: that's not true.

Why the bathroom deserves as much attention as the living room

We spend an average of 30 minutes a day in the bathroom. Sometimes more if you like long baths or skincare rituals. It's a contemplative, idle time, where your gaze inevitably lands somewhere.

In my Berlin studio, the bathroom overlooks a bare wall that I saw every morning while brushing my teeth. It annoyed me. I installed a monochrome silkscreen print — a fragmented face, 50×70 cm — and everything changed. Waking up became less jarring. The morning ritual, softer.

The bathroom is one of the rare rooms where you are alone, in direct contact with yourself. It might as well be visually stimulating. Unlike the living room where artworks "perform" socially (we show them off, we talk about them), here they create intimacy. A silent dialogue.

And let's face it: a bathroom with bare walls is sad. Even if the tiling is impeccable and the fixtures are designer, it lacks that touch that transforms a functional space into a liveable place.

Bathroom artwork: which materials truly survive humidity

First question everyone asks me: "But won't it get moldy?" No, if you choose the right supports.

Supports that last

Acrylic under glass or plexiglass: my first choice. The artwork is protected, humidity only affects the frame. I have a pop art painting framed under plexiglass in my bathroom since 2021, zero damage.

Prints on Dibond or aluminum: printed directly on metal, these supports are completely waterproof. Perfect for bathrooms with walk-in showers where steam spreads everywhere. The look is modern, almost industrial.

Varnished canvases: if you absolutely want a traditional canvas, you need a satin or glossy protective varnish. This creates a barrier against humidity. However, avoid untreated canvases or paper artworks without frames — that's a guaranteed disaster.

What to absolutely avoid

Unframed watercolors. Old unframed engravings. Untreated raw wood frames (they swell, warp). Papier-mâché artworks or unprotected organic materials.

A client told me he hung a lithograph without glass in his bathroom — in six months, the paper had warped and the colors had faded. Too bad, it was a signed piece.

Bathroom painting: what size, what placement

Size is always tricky. Too small, the artwork gets lost in the tiling. Too big, it overwhelms the space.

For a standard bathroom (5-8 m²), I recommend a size between 40×60 cm and 70×100 cm. It remains visible without being intrusive. If you have a large bathroom with a freestanding tub (the luxury), you can go up to 100×150 cm.

The ideal location? Opposite the bathtub or sink. That's where your gaze naturally falls. Avoid walls directly above the shower (direct water splashes) or too close to the floor (risk of splashing).

In my old Parisian apartment, I had a long corridor leading to the bathroom. I installed three small formats in a series (30×40 cm each) on the back wall, visible from the door. It created a real scenography.

Pro tip: if your ventilation system is noisy or you hate absolute silence in the shower, a strong graphic artwork diverts attention. The brain focuses on shapes, colors, and less on the auditory environment. Strange, but it works.

Themes that work (and those to avoid)

I have my preferences, of course. But some themes consistently appear in successful bathrooms.

What always works

Seascapes, beaches, waves. Classic, but effective. Water calls to water. A client bought a black and white photo of the Norwegian coastline from me — he says every shower becomes an almost meditative experience.

Artistic nudes (not vulgar, mind you). The bathroom is the territory of the body. A graphic, stylized nude makes sense. In my current bathroom, I have a minimalist female nude, three ink strokes. Clean.

Geometric or organic abstractions. Fluid shapes, soft colors (or, on the contrary, very vibrant to energize the morning). It tells no narrative, it just creates an atmosphere. Seascapes and fluid abstractions are among my safe bets for this room.

What I strongly advise against

Motivational quotes in script font ("Breathe," "Relax," that kind of thing). That was trendy in 2015, now it's dated. Still lifes with fruit (too kitsch in this context). Too realistic portraits that stare at you (unnerving when you're naked).

And most importantly, avoid overly emotionally charged artworks. A dramatic scene, a war photo, an expressionistic scream... The bathroom should remain a refuge, not a place of intense visual confrontation.

Decorative wall panels for the bathroom: the alternative to classic paintings

If framed paintings seem too formal, there are other options.

Brushed aluminum panels with photographic print: ultra-resistant, direct wall mounting without a frame. I used one for a series of minimalist contemporary portraits in my Berlin bathroom. The rendering is raw, almost street art.

Printed tempered glass plates: increasingly common, especially for reproductions of contemporary artworks. They clean like a mirror, zero maintenance.

Artistic wall mosaics: if you're renovating your bathroom, why not integrate the artwork directly into the tiling? I've seen projects where an entire wall becomes an abstract ceramic composition. It's work, but the result is permanent and spectacular.

My personal opinion: rigid panels are less "precious" than a framed painting, but they bring a raw modernity. If your interior is rather industrial or minimalist, it's a great option.

How to prevent your bathroom painting from getting damaged

A few common-sense rules for your artwork to last for years.

1. Proper ventilation. A well-functioning ventilation system reduces ambient humidity. If your bathroom tends to turn into a hammam after every shower, even the best varnish won't last forever.

2. Distance from water sources. Even if the support is waterproof, avoid hanging it directly above the bathtub or in the direct line of the showerhead. A little distance, and everything will be fine.

3. Treated or metal frames. Untreated wooden frames swell. I've seen old frames crack in three months. Opt for aluminum, steel, or varnished wood.

4. Visual check once a quarter. You check for moisture traces under the glass, if the frame is moving. Five minutes, no more. If you see the beginning of a problem, act immediately.

One of my Parisian collectors installed a small, discreet electric dehumidifier in his bathroom (inexpensive, €40 on Amazon). Since then, zero problems. It might be excessive, but if you have a particularly humid room, it can be worth it.

My recommendations based on your bathroom style

Because not all bathrooms are alike.

Modern/minimalist bathroom

Graphic black and white painting. Geometric abstraction. Clean lines, no frills. A medium size (60×80), thin black or white aluminum frame. It reinforces the minimalist aesthetic.

Vintage/retro bathroom

Botanical engraving under glass, old poster (Art Deco typography), or sepia photograph. Light varnished wooden frame. Avoid total kitsch, stick to elegant vintage.

Zen/spa bathroom

Soothing natural landscape (forest, water, stone). Neutral tones (beige, gray, soft green). Panoramic format if you have a long wall. The idea: to extend the feeling of relaxation.

Colorful/eclectic bathroom

Pop art painting, vibrant portrait, multicolored abstraction. Here, you can dare. A large format (80×120) that pops. White or transparent frame to avoid weighing it down.

In my current bathroom (white tiles, black fixtures), I put a female portrait in fluorescent pink and electric blue acrylic. It wakes you up, literally. Every morning, this painting puts me in a good mood.

Wall decor for the bathroom: what if you created a mini-gallery

Instead of a single imposing artwork, you can create a gallery wall.

I did this in my Berlin bathroom: six small formats (20×30 and 30×40) arranged in an asymmetrical grid. Black and white only, varied themes (portrait, urban, abstract). Identical frames, black aluminum.

The advantage: you can change an artwork from time to time without redoing everything. It becomes an evolving collection. And visually, it creates rhythm.

Technical advice: if you're creating a gallery wall, maintain chromatic or stylistic consistency. Otherwise, it turns into a mess. Either unify by colors, or by frames, or by theme.

Also, be careful not to overload. In a small bathroom, three artworks max. Beyond that, it suffocates.

Where to find the perfect painting for your bathroom (without breaking the bank)

You have several options, depending on your budget and desires.

Online galleries (like mine, alessiocacciatore.com): you find original artworks or limited editions, often at more accessible prices than in physical galleries. The advantage is that you can filter by size, color, style.

Limited edition art prints: cheaper than a unique piece, but with real artistic value. Look for emerging artists, numbered silkscreen prints, signed photos.

Local art markets and artist studios: if you like to browse, you can stumble upon gems. I have a friend who found a framed watercolor under glass for €80 from an artist in Belleville. Three years later, it's still perfect.

DIY prints on waterproof supports: some photo labs offer prints on Dibond or aluminum from your own files. If you have an eye for composition, you can print a personal photo and create something unique.

Avoid cheap unframed posters. Even if the visual is beautiful, without protection, it won't last. Invest at least in a decent frame with glass.

Frequently asked questions

Can you put a painting in a bathroom with a shower?

Yes, provided you choose a resistant support (acrylic under glass, Dibond, aluminum) and install it away from direct water splashes. Good ventilation also helps. I myself have paintings in my bathrooms with showers for years, zero problems.

What size painting for a small bathroom?

For a bathroom under 5 m², stay between 40×60 cm and 60×80 cm maximum. Beyond that, it overwhelms the space. If you want several artworks, opt for small formats (30×40) in a wall composition.

Do canvas paintings hold up in a humid bathroom?

Yes, if the canvas is properly varnished with a protective satin or glossy varnish. Without protection, the canvas risks warping or molding. However, prefer more waterproof supports if your humidity level is very high.

Where to hang a painting in the bathroom?

Ideally opposite the bathtub, above the sink (not too close to avoid splashes), or on the wall opposite the door. Avoid directly above the shower or too close to the floor.

Is a painting in the bathroom really useful?

Aesthetically, absolutely. The bathroom is an intimate room where you spend time alone — it might as well be visually pleasant. It transforms a functional space into a liveable place. After all, if you prefer bare walls, that's up to you.
