22 Small Space Bathroom Design Ideas
Let’s be real—designing a small bathroom feels like playing Tetris with sinks, mirrors, and towels.
The space is tight, the storage is limited, and somehow you still want it to look like a spa retreat rather than a broom closet.
Don’t worry, I’ve been there—once had a bathroom so tiny that when I bent down to pick up the soap, my head practically hit the wall.
Through trial, error, and a bit of design obsession, I’ve collected practical, stylish, and surprisingly clever ways to make a small bathroom shine.
1. Install a Floating Vanity
A floating vanity makes the floor visible underneath, which instantly tricks the eye into thinking the bathroom is larger.
More than just a design move, it makes cleaning a breeze. You can slide baskets underneath for storage, keeping the clutter off the counter.
When I switched to a floating vanity in my guest bathroom, even my guests commented on how “airy” it felt. Bonus: no more dust bunnies hiding in unreachable corners.
2. Use Large Format Tiles
Here’s a small-space secret: large tiles create an illusion of space. The fewer grout lines you see, the less “chopped up” the floor or wall looks. Studies in design psychology show that visual continuity plays a huge role in how big a room feels.
A friend of mine replaced tiny mosaic tiles with 24×24 porcelain tiles, and the difference was night and day. Suddenly, her narrow bathroom didn’t feel like a hallway anymore—it felt sleek and modern.
3. Add a Big Mirror
You’ve heard it before, but it’s worth repeating: mirrors double the perception of space. In bathrooms, they also bounce light around, making the room brighter.
The trick is going oversized. Don’t settle for a small mirror above the sink—stretch it across the wall if you can. I once framed an entire wall with a custom mirror in my apartment bathroom. The room didn’t just look bigger; it felt bigger.
4. Opt for a Sliding Door
Traditional swinging doors eat up precious real estate. A sliding barn door or pocket door saves space and adds character. It’s particularly game-changing in bathrooms that open directly into tight hallways.
According to a survey by Houzz, 38% of homeowners with small bathrooms now prefer sliding doors for accessibility and space-saving.
5. Choose a Corner Sink
Corners are often wasted space. A corner sink is a brilliant way to reclaim those forgotten angles. These sinks work wonders in powder rooms or half baths, where space is limited but you still need functionality.
When I renovated my tiny guest bath, installing a corner sink freed up just enough room to add a slim shelf for hand towels.
6. Install Glass Shower Doors
A shower curtain cuts the room visually, making it feel smaller. Clear glass doors erase that boundary, letting your eye see the full length of the bathroom.
If frosted glass is your vibe, you’ll still gain the sense of openness without sacrificing privacy. Plus, glass is easier to clean than fabric curtains that trap mold and mildew.
7. Go Vertical with Storage
When floor space runs out, look up. Install open shelving above the toilet, use ladder shelves, or mount cabinets closer to the ceiling.
Statistically, the average bathroom is only 40 square feet in urban apartments, so maximizing vertical space is essential. I personally swear by floating shelves above my toilet—they hold baskets of toiletries, keeping the vanity clear.
8. Pick Light Colors
Light shades expand space visually. Whites, soft grays, and pastels reflect more light, creating a brighter, airier vibe.
Dark colors have their place, but in a small bathroom, they tend to close the room in. If you love drama, try a dark vanity paired with light walls to balance things out.
9. Use Wall-Mounted Faucets
Wall-mounted faucets allow you to install slimmer vanities since the faucet doesn’t need counter depth. That little adjustment can save you several inches—crucial in tiny layouts.
Design pros often recommend this move for powder rooms, where every square inch matters.
10. Add Recessed Niches
Instead of bulky shelves sticking out into your shower, carve out recessed niches. They’re sleek, functional, and eliminate clutter.
I remember visiting a friend’s loft where every shampoo bottle had a perfectly sized cubby in the shower wall. Not only did it look chic, it saved space where a shower caddy would normally dangle awkwardly.
11. Choose Compact Fixtures
Not all toilets and sinks are created equal. Brands now make compact versions designed specifically for small spaces. These models often have shorter projections, meaning they stick out less from the wall.
Statistics show that compact toilets can save up to 6 inches compared to standard models—a game-changer in tight layouts.
12. Embrace Open Shelving
Open shelving keeps things feeling light compared to bulky cabinets. Just be mindful of organization. Neatly folded towels and attractive baskets turn open shelves into decor.
I once swapped out a clunky vanity cabinet for open shelves. The trade-off in hidden storage was worth it, because the room instantly felt more breathable.
13. Add Plenty of Lighting
Small bathrooms often lack natural light, so layered lighting is key. Overhead lights, sconces beside the mirror, and even LED strips under shelves can transform the vibe.
According to the American Lighting Association, bathrooms need at least 50 lumens per square foot. In smaller spaces, this means using multiple light sources rather than relying on one ceiling bulb.
14. Install a Pocket Shelf
Sometimes, it’s the little touches. A pocket shelf built into the wall near the sink or toilet offers storage without eating up space. Perfect for stashing extra rolls of toilet paper or hand soap.
Think of it as a secret cubbyhole that works harder than it looks.
15. Use Pattern Wisely
Bold patterns can actually work in small spaces—as long as you use them carefully. A statement wall with wallpaper or patterned tiles creates drama without overwhelming the entire room.
I once used a herringbone tile pattern on a single wall behind the sink in a cramped bathroom. Suddenly, it became a feature, drawing attention away from the room’s small size.
16. Hang Hooks Instead of Bars
Hooks take up less space than towel bars and can hold multiple items. Perfect for tight layouts where every inch of wall counts.
Plus, they give a casual, spa-like feel. My tiny bathroom at one point had five hooks lined up—towels, robes, and even a plant hanging from one of them.
17. Install a Pedestal Sink
A pedestal sink frees up visual space by removing bulky cabinetry. While you lose some under-sink storage, the payoff is a sleeker look.
It’s a classic choice for small powder rooms and guest baths where storage isn’t the top priority.
18. Use Clear or Floating Storage
Transparent acrylic organizers or floating storage solutions help reduce visual clutter. They don’t block sight lines and keep essentials handy.
Think floating toothbrush holders, acrylic trays, or even clear stackable bins under a floating vanity.
19. Go Frameless with Your Mirror
A frameless mirror eliminates unnecessary borders, letting the reflection flow seamlessly. It’s a subtle trick, but one that adds to the feeling of openness.
Designers often recommend this in ultra-small bathrooms because every visual detail counts.
20. Add a Skylight or Solar Tube
If you can, bringing in natural light is the ultimate space-enhancer. Skylights or solar tubes brighten up bathrooms dramatically.
Even small additions of natural light improve not just aesthetics but also energy efficiency. Bathrooms with daylight use up to 25% less electricity.
21. Keep It Minimalist
Clutter is the enemy of small bathrooms. Go minimalist with only the essentials—streamlined fixtures, neutral palettes, and well-chosen accessories.
When I downsized, I got ruthless: only two sets of towels, one soap dish, one plant. The simplicity transformed my bathroom into a stress-free retreat.
22. Use Multi-Functional Furniture
In tiny spaces, everything should earn its keep. Think mirrors with built-in storage, stools that double as towel racks, or vanities with hidden compartments.
These clever hybrids keep the space practical without crowding it.
