15 Inspiring Blue and Gray Bathroom Ideas

Here are 15 blue and gray bathroom ideas that range from bold and dramatic to subtle and sophisticated. The best part is you can mix and match elements from different ideas to create that’s uniquely yours. Blue and gray together create a look which makes a visual interest and makes your bathroom yours uniquely.
So, let’s dig into the ideas and pick out the best one for you.
Statement look with deep blue tiles

Okay, let me tell you about my favorite looks. Deep navy blue tiles covering a shower wall or the low half of your bathroom walls. The rich color makes a bold statement. Pair this with light gray walls and white fixtures for an amazing look.
The contrast is what makes this work well. The deep blue gives a luxury vibe, while the gray keeps things from feeling overwhelming.
I saw this in a friend’s bathroom and it looked the best. The blue tiles had sheen to them that caught the light. When you’re soaking in a tub facing a blue tile wall, it creates a spa-like feel.
Blue and grey patterned wall

For personality, try a patterned wall that combines blue and gray. Wallpaper works great in a bathroom space. Look for patterns like geometric shapes, watercolor effects, or floral designs that incorporate both colors.
Keep the rest of the bathroom simple when you consider this. White fixtures and minimal décor let that beautiful pattern shine.
What’s good about this approach is how it changes the feel of your space. It’s a great option for renters since peel-and-stick wallpaper can be removed without damage.
Gray mosaic tiles in light blue bathroom

I adore this combination. Paint your walls a soft, pale blue like sky on a clear day then add gray mosaic tiles around your shower or as a backsplash behind the sink.
The texture of the mosaic tiles against the smooth painted walls creates a beautiful contrast. The gray adds sophistication while the light blue keeps things feeling fresh and clean.
This look works well in bathrooms with good natural light. The light plays off the mosaic tiles and makes the whole room feel dynamic and interesting.
Modern blue bathroom with black fixtures

This look makes a bold statement. Start with medium blue walls or cabinetry and then add gray flooring or countertops and then add a touch of matte black fixtures.
Black faucets, shower heads, and cabinet hardware pop against the blue and gray backdrop, it’s modern without feeling uninviting.
I tried this in a small powder room, and visitors always comment on how cool it looks. There’s something about that black and blue combo that feels both classic and current.
Silver shower kit in light blue bathroom

Light blue walls create a gorgeous, airy feeling in a bathroom. When you add a sleek silver shower kit, it becomes the highlight of the bathroom.
The silver catches light and adds glamour. Choose gray towels and bath mats to tie everything together.
This combination feels clean and timeless. The blue is soothing, the silver adds shine, and the gray grounds everything.
Floral shower curtain in gray bathroom

Gray is a wonderful neutral for bathroom walls. It’s calm but not boring, add a shower curtain with blue floral patterns, and your bathroom creates personality.
This is an easy update for renters or anyone who doesn’t want to commit to permanent changes. You can switch out the shower curtain anytime you want a fresh look.
Blue flowers against a white or light blue background work beautifully. Add blue towels and a blue jar for cotton balls, and your gray bathroom feels cohesive and intentional.
Deep blue dual vanities against gray wall

If you’re lucky to have space for double sinks, this idea is what you need to go for. Gray walls, not dark, not light and against them sit two stunning navy blue vanities with white countertops.
The contrast is beautiful, and the symmetry creates a sense of luxury. Add silver hardware and mirrors with silver frames to complete the look.
I saw this in a home magazine and couldn’t stop thinking about it. It’s perfect for a bathroom where you want something more dramatic than the white vanities.
Coastal blue bathroom with gray accents

This is a happy, breezy look. Start with walls in a medium blue and add gray tile flooring, maybe with a weathered look.
Incorporate white fixtures and natural wood elements to complete that coastal vibe. Gray towels and a gray bath mat tie in with the flooring. It creates a relaxing and cheerful vibe.
Silver framed mirror as a focal point

Gray walls make a perfect backdrop for a statement mirror with a silver frame. Choose an ornate or an arched shape to create a focal point.
Add blue towels, a blue rug, some blue soap dispensers or vases to bring in the color scheme. The mirror becomes the star while the blue and gray create harmony.
This approach is perfect if you’re not ready for renovations. A beautiful mirror can transform a bathroom without changing any features.
White bathtub in blue and gray marble walls

If you’re planning a renovation, this idea is stunning. Imagine marble tiles with blue and gray veining covering your bathroom walls. Against a luxurious backdrop sits a classic white freestanding tub.
The marble brings in both your blue and gray colors in a natural, organic way. The white tub stands out beautifully against the patterned walls. This look is timeless and elegant.
Blue panelling with gray upper wall

Wainscoting or beadboard painted a blue on the lower half of your walls creates wonderful texture and interest. Paint the upper walls a soft gray for a perfect pairing.
This two-tone look adds architectural interest in a simple bathroom. It works with both modern and traditional styles, depending on your fixtures and accessories.
I love how this approach defines the space and adds character without overwhelming the room.
Pedestal sink with blue and gray wallpaper

A white pedestal sink is classic and space-saving. When you pair it with wallpaper featuring blue and gray patterns, it becomes part of a design.
Look for wallpaper with patterns like geometric, floral, or a subtle stripe. The sink stands out against the patterned background while feeling connected to the overall design.
This combination works in powder rooms where you want something dramatic or fun.
Dark blue door in light gray bathroom

Paint your bathroom door a deep, rich blue while keeping the walls a soft gray. This unexpected pop of color wheel makes a statement.
The gray walls keep things serene while the blue door adds personality and charm. It’s an approach that makes your bathroom feel custom and thoughtful.
You can tie in the blue with hand towels or artwork to create a cohesive feel throughout the space.
Blue and gray bathroom with red accents

Blue and gray create a lovely, cool palette. Adding touches of red brings warmth and energy to balance things out.
Like small red accessories like a vase, candle, or artwork with red elements. These pops of color stand out beautifully against the blue and gray background.
This approach is perfect if you think blue and gray feeling cold or impersonal. The red adds warmth without looking too much.
Blue-gray floor tiles with geometric pattern

Blue-gray is a gorgeous in-between shade that works as a neutral while having color.
Geometric patterned floor tiles in blue-gray tones create visual interest. Keep walls simple like white or light gray, to let the floor shine.
These tiles work in both modern and traditional spaces. They’re interesting without being trendy, which means they’ll look good for many years.
What color looks good in a gray and blue bathroom?
With a blue and gray base, there are many other colors that play nicely with it. You have several great options.
White is always a safe bet. It brightens up the space and creates clean lines against your blue and gray elements.
Warm metals like brass or gold look amazing with blue and gray. A brass faucet or gold-framed mirror adds warmth and luxury to the tones of blue and gray.
Wood tones bring natural warmth. A wooden vanity, shelves, or wooden accessories like a stool or tray add organic texture that balances the cool blues and grays.
For small accents, consider yellow for a pop, coral for a trend, or green for a natural connection.
Black works beautifully as an accent color too. Black fixtures or frame details create definition and contrast and balance against light blues and grays.
