15 Small Apartment Interior Design Modern Bathroom Ideas
Let’s be honest for a second—designing a bathroom in a small apartment feels like trying to fold a fitted sheet. You know it can be done, but you also know you’ll probably question your life choices along the way. And if your bathroom is anything like mine used to be—tiny, echoey, and full of “What were the builders thinking?” moments—then you’ve definitely had those late-night Pinterest spirals searching for modern bathroom inspiration.
But here’s the good news: modern bathroom design absolutely thrives in small spaces. In fact, many of the most stylish bathrooms I’ve seen came from apartments where every inch counts. Ever wondered why that is? Because small spaces force creativity, and creativity leads to genius solutions.
So if you’re ready to transform your apartment bathroom into something sleek, modern, functional, and—dare I say—relaxing, then buckle up. I’ve got 15 small apartment interior design ideas for a modern bathroom that will make you rethink what’s possible in tight quarters.
You’ll see clever layouts, minimalistic fixtures, chic materials, and lots of style packed into compact spaces. And I’ll throw in some personal experiences, a little humor, and a few FYIs to keep things fun. 🙂
Let’s jump in!
1. Minimalist Marble Retreat
Marble in a small bathroom sounds like a luxury magazine fantasy—until you realize it’s actually one of the easiest ways to make a compact space look bigger and more modern. I once added a marble backsplash in a tiny rental, and suddenly guests thought I lived in a penthouse. (I absolutely did not.)
So what makes the Minimalist Marble Retreat so effective?
Why It Works
- Continuous marble veining creates visual flow.
- Floating vanity opens floor space.
- Frameless glass shower eliminates visual barriers.
- Warm LED accents prevent the cold, sterile look.
Pro Tip
Use marble-look porcelain tiles if you’re on a budget. Honestly, most people can’t tell the difference unless they lick the walls—IMO, if someone licks your walls, that’s their problem, not yours.
Best For
Small apartments craving a bit of luxury without sacrificing simplicity.
2. Soft Pastel Serenity
Pastels have made a major comeback, and I’m not talking about the baby-blue bathrooms from the ’70s. Modern pastel bathrooms feel airy, bright, and totally Instagrammable.
Why It Works
- Light hues like blush pink, mint, or cloud blue reflect more light.
- Pairing pastels with light-wood finishes creates a soft Scandinavian vibe.
- A round illuminated mirror adds that dreamy modern flair.
A Personal Note
I once painted a tiny bathroom in a pale rose hue, expecting chaos. It ended up looking spa-like—who knew?
Rhetorical Question
Ever noticed how a small space instantly feels calmer when the colors stop screaming?
3. Urban Chic Concrete
If you love industrial style, this one’s for you. Concrete instantly delivers that edgy urban vibe without making your space feel cold or cave-like—if you do it right.
Why It Works
- Smooth concrete walls create depth.
- Black matte fixtures feel bold and modern.
- Niche storage avoids bulky cabinets.
- Warm backlighting balances the cool materials.
Real Talk
Concrete bathrooms always look like they belong in a cool boutique hotel, and who doesn’t want that energy at home?
Slang Moment
If you want your bathroom to look “high-key chic,” this is the move.
4. Scandinavian Fresh Glow
Let’s talk Scandinavia—a place where winters are dark, apartments are small, and design skills are absolutely elite. When you adopt the Scandinavian approach, you make your bathroom feel simple, functional, and refreshing.
Why It Works
- White tiles brighten the space.
- Natural oak adds warmth.
- Plants bring life and contrast.
- Diffuse daylight stops harsh shadows.
Engaging Question

5. Luxe Gold Accents
Gold can instantly make a modern bathroom look stylish and expensive—even in a space the size of a toaster. But the trick is moderation.
Why It Works
- Gold reflects light beautifully.
- Works great with white glossy surfaces.
- Adds elegance without clutter.
Key Elements
- Gold faucets
- Thin gold frames

IMO
Gold is like seasoning—use just enough to elevate the dish. Too much, and you’re in tacky territory. :/

If you dream of escaping to a spa but life keeps handing you deadlines, bills, and questionable neighbors, then bring the spa to your bathroom.
Why It Works

My friend did a monochrome makeover in her tiny studio unit, and it made the space look straight out of a modern art gallery.

Wet rooms maximize small spaces by eliminating the need for bulky shower enclosures. Everything flows—and not just the water.
Why It Works
- Floor-to-ceiling tiles create cohesion.

Maintenance FYI

Why It Works
- Adds warmth without clutter.
- Pairs beautifully with matte-white fixtures.

But Beware
White shows everything—dust, splashes, your existential dread—so keep cleaning supplies handy.

If you want bold, you want matte black. It’s modern, sleek, fearless—and incredibly photogenic.
