10 Small Dark Blue Bathroom Ideas: Transforming Small Spaces with Dark Blue Elegance

Once, a client asked me to design a bathroom entirely in dark blue — ceiling, walls, even the door. I almost thought they were joking, because in a small space that could go from chic to claustrophobic real quick. But with the right balance of light and material, we made it feel like a boutique hotel powder room. That’s the beauty of small spaces: they push you to be more creative than you ever thought possible. Today, I’ll share 10 small dark blue bathroom ideas from my own projects that just might inspire your next makeover.

1. Navy Walls with Gold Fixtures

There’s something timeless about pairing deep navy with warm gold. It instantly elevates a compact bathroom, making it feel luxurious without needing marble everywhere. Just be mindful of lighting — I often soften the tone with warm LED sconces, so it doesn’t feel cold. In one recent remodel, gold handles and a mirror frame really pulled the look together.

2. Half-Wall Tiling

If you’re afraid of going all-in with dark blue, try half-wall tiles in a rich hue and keep the upper part white or light grey. This gives depth but allows the space to still breathe. Easy to maintain and surprisingly budget-friendly.

3. Dark Blue Vanity

A painted vanity is like the little black dress of bathrooms — understated, adaptable, and flattering in almost any setting. I’ve transformed old wooden cabinets with a few coats of navy enamel and new hardware, instantly giving them a designer edge.

4. Matte Finish Tiles

Glossy tiles can bounce light, but matte dark blue tiles add a modern, moody vibe. They also hide water spots better. Just remember, matte can make the space feel more closed in, so add mirrors strategically.

5. Blue Mosaic Accent Wall

One client wanted “underwater escape” vibes. We installed a dark blue mosaic sheet behind the mirror — it felt like a piece of art. This works particularly well in narrow spaces where you want a focal point in the middle of the visual field.

6. Floating Shelves in Light Wood

Pairing dark blue walls with light oak shelves keeps everything from feeling too heavy. The shelves break up the color block while serving as compact storage. I’ve done this above toilets or next to mirrors in small urban apartments, and it’s both practical and pretty.

7. Statement Floor Tiles

If your walls are dark blue and simple, go for bold patterned floors — think Moroccan or geometric tiles. It adds an element of surprise when you walk in, and distracts from the compact size of the room.

8. Paint the Ceiling

Yes, even in a small bathroom! Painting the ceiling the same dark blue as the walls can create a cocooning effect. I once did this in a loft ensuite, adding a large round mirror to reflect the light and make it magical.

9. Glass Shower Screen

Solid shower curtains can close off a small bathroom, making it feel narrow. Glass screens let the dark blue backdrop stay visible and keep the space visually open. Plus, they’re easier to clean than some think.

10. Mix Metal Finishes

Dark blue is incredibly versatile with metals — chrome, brass, matte black all work. I often mix two finishes to give layers of texture, like black taps with a brushed brass light fitting in a compact guest bathroom. This keeps the look collected yet intentional.
