10 Bathroom Décor Mistakes That Make Small Spaces Feel Even More Cramped

A small bathroom doesn’t have to feel limiting. However, the wrong design elements can make it feel even tinier than it already is. From bulky fixtures to overly busy finishes, certain décor decisions visually shrink a space, cutting off sight lines and adding unnecessary weight. 

The good news? Most of these mistakes are easy to rethink. We’ve asked designers to share the most common bathroom décor missteps that they see—and how to fix them.

Choosing an Oversized Vanity

A bulky vanity that dominates your bathroom can quickly throw off the entire design scheme. It limits visible floor space, and interrupts a room's natural flow.

“It impedes walkways, and can make a bathroom feel tight,” says Debbie Mathews LeRoy, owner and principal designer of Debbie Mathews Antiques & Designs. 

The Fix: Opt for a more compact or leggy design—like a pedestal or floating vanity. This shows more floor space, and creates a sense of openness.

Using Dark Colors Everywhere

Dark tones seem striking, but they’re less forgiving in a small bathroom you use every day. When carried across both walls and flooring, they tend to pull the space inward, making it feel more enclosed. 

“It can make the space feel cave-like,” says Brian Keller, CEO and founder of Rorra. You don't need to avoid these tones entirely—but using them wall-to-wall can quickly tip the room from moody to cramped.

The Fix: A better approach is balance. Pair lighter walls with darker accents, or limit deeper hues to a single feature wall. This will maintain depth, without shrinking the room.

Hanging Mirrors That Are Too Small

“Mirrors are one of the most powerful tools for expanding perceived space,” Keller says. That potential is entirely lost when yours is undersized. 

It doesn’t just look off—this proportional problem cuts off light and shortens sight lines. In a smaller bathroom, a mirror should feel slightly generous, rather than perfectly scaled.

The Fix: Go larger than you think—like a mirror that spans the width of the vanity. This will help reflect light and draw the eye upward.

Overloading the Space With Patterns

Layering patterned tile, textiles, and wallpaper might feel expressive, but in a small bathroom, it quickly becomes visual noise. When every surface is competing for attention, the room loses any sense of openness or flow—it starts to feel busy, rather than intentional.

The Fix: To keep things feeling open, choose one standout pattern, and let everything else fall back. In a smaller bathroom, you often have to go more minimal than you think, whether that’s a stripe, a single bold tile, or one strong color.

Cluttering Surfaces and Walls

Too many accessories, rugs, or decorative accents can quickly overwhelm a small bathroom. When every surface is filled, the space starts to feel crowded, with no clear place for the eye to land. LeRoy recommends keeping these decorative items to a minimum.

The Fix: Focus on a few intentional pieces that serve both form and function—your towels, soap, or even everyday vanity items can double as decoration when chosen thoughtfully.

Installing Heavy Shower Curtains

A thick or opaque shower curtain can visually divide the room, making it feel more confined. It creates a hard stop for the eye, breaking up sight lines and making the overall footprint read as smaller than it is.

Lighter, more translucent materials—or better yet, glass—help keep everything visually connected. “The shower should feel like part of the bathroom, not a separate compartment,” Keller adds.

The Fix: Swap in a sheer curtain—or, if possible, a frameless glass door.

Choosing Oversized or Decorative Lighting

A large chandelier feels like an easy way to make a statement. However, in a small bathroom, it does the opposite, and overpowers the space, while leaving corners in shadow.

The scale can feel disproportionate, and instead of elevating the room, it draws attention to how little space there is. “Multiple, simple layers of lighting can work better,” says LeRoy.

The Fix: Incorporate sconces, recessed lighting, or a small pendant to evenly distribute light and open up the room.

Ignoring Vertical Space

Keeping everything at eye level creates a compressed, horizontal feel that can make a small bathroom seem shorter and more confined. When nothing draws the gaze upward, the room visually stops too soon, reinforcing that boxed-in effect.

The Fix: Draw the eye upward with tall mirrors, vertical tile layouts, or elevated lighting to make ceilings feel higher.

Mixing Too Many Finishes

“The eye registers each finish as a separate element,” Keller says. Combining multiple metals and finishes can fragment the space visually and make it feel crowded.

The Fix: Stick to one or two finishes to create a more unified, expansive look.

Relying on Overhead Lighting

Relying on a single overhead fixture tends to flatten any room, especially the bathroom. This approach creates a harsh, one-dimensional light that does little to open up the space. 

The Fix:  “Lighting from multiple angles opens up corners and gives the room depth,” Keller says. Layer your lighting—use sconces at eye level, soft ambient lighting, and a subtle overhead source. This will build depth and soften edges.
