If you’ve been feeling like your bathroom is a bit… well, beige, you’ve come to the right place. We’re diving deep into the world of cobalt blues and sunny yellows. This color combo is the ultimate “mood booster”—it’s like stepping into a Mediterranean vacation every time you brush your teeth.I’ve rounded up 10 stunning spaces that show exactly how to pull off this daring duo, whether you’re into vintage vibes or sleek modern lines. Let’s get inspired!
1. Royal Reflections
If you want to feel like royalty while getting ready in the morning, this is the blueprint. This space goes all-in on traditional Mediterranean patterns. What I love most is that they didn’t stop at the walls; they actually found a yellow toilet and sink! It sounds wild, but against that deep navy vanity and the arched mirror, it looks incredibly intentional and high-end. The gold filigree detail on the blue door in the reflection is that “chef’s kiss” finishing touch. It’s bold, it’s busy, and it’s absolutely beautiful.
2. Modern Sunshine
This one is for the fans of a clean, mid-century look. We’ve got classic blue subway tiles stacked vertically, which makes the ceiling feel miles high. The star of the show here is definitely that honey-toned wood vanity with the long brass legs. It’s a softer way to do “yellow” without using actual paint. Pro tip from this photo: if you have a bold blue wall, throw in some bright yellow towels and a single red flower to break up the cool tones. It keeps the room feeling warm and lived-in rather than like a cold showroom.
3. Mosaic Magic
Can’t decide on just one pattern? Use them all! This shower is a masterpiece of multi-colored talavera tiles. By keeping the rest of the walls a solid, bright yellow and a flat cobalt blue, the busy shower niche doesn’t feel overwhelming—it feels like art. I also dig the floating teal vanity; it adds a third “cool” tone that bridges the gap between the blue tiles and the yellow walls. It’s funky, artistic, and definitely a conversation starter.
4. Pastels & Petals
If the other bathrooms are a loud “hello!”, this one is a gentle “good morning.” By swapping cobalt for a soft sky blue, the room feels much airier. The pop of yellow comes from that gorgeous clawfoot tub. Seriously, who wouldn’t want to soak in a giant yellow lemon? The “White Daisy” and “Yellow Sun” artwork on the walls keeps the vibe playful and family-friendly. It proves that you can do a colorful bathroom without it feeling heavy or dark.
5. Luxe Indigo
This is pure luxury. We’re talking deep indigo cabinetry paired with a crisp marble countertop. The yellow here is coming from those glossy square tiles that go all the way to the ceiling. What makes this work is the lighting—those vintage-style brass lanterns cast a warm glow that makes the yellow tiles look like they’re glowing. If you’re worried about blue and yellow looking “too primary,” go for these richer, darker shades of navy and mustard.
6. Classic Contrast
This looks like the ultimate “weekend DIY” inspiration. It’s a standard bathroom layout elevated by vibrant blue tiling. The white vanity and toilet act as a “palette cleanser” so the blue doesn’t swallow the room. The yellow accents here are super easy to swap out—a shower curtain, a bath mat, and some fresh flowers. It’s the perfect example of how you can completely change the energy of a white-and-blue room just by adding a few sunny textiles.
7. Preppy Chic
I am obsessed with the sophistication here. This is “Coastal Grandmother” meets “City Chic.” The navy blue vanity is super grounded and classic, especially with those gold knobs. By painting only the top half of the wall a soft marigold yellow and using white subway tiles on the bottom, the room stays bright and reflective. That blue and white patterned rug adds just enough texture to keep your feet happy on the cold tile.
8. Midnight Bloom
Feeling brave? Why not paint the ceiling! This bathroom uses a monochromatic dark blue on the walls and ceiling, which creates a cozy, cocoon-like feeling. Because the walls are so dark, the yellow daisy shower curtain practically jumps out at you. It’s a great lesson in contrast: the darker the blue, the brighter the yellow will seem. The natural wood floating shelves add a bit of organic warmth so the room doesn’t feel too “industrial.”
9. Golden Hour
This bathroom is a masterclass in balance. You have a very traditional white wainscoting and a classic tub, but then—BAM—stunning yellow ochre walls. The blue is used sparingly here, mainly in the Roman shade and the towels, which makes the blue feel like the accent rather than the main event. It’s elegant, timeless, and feels like it belongs in a high-end boutique hotel.
10. Exotic Elegance
We saved the most dramatic for last. This looks like a hidden spa in Morocco. The textured yellow plaster walls have so much depth, and that vertical blue tile inlay behind the tub is stunning. The floor is the real winner, though—a golden mosaic with a blue and red mandala design. It’s proof that when you use rich textures and intricate patterns, blue and yellow can feel incredibly exotic and soulful.
11. Polished Patterns
This is probably the most “livable” version of the trend if you’re a fan of traditional styles. The navy blue trim around the window and the matching vanity give the room a really cohesive, “designed” feel. That ochre-yellow wall color is warm and inviting without being neon. But the real star? The Mediterranean-style floor tiles. They add just enough pattern to keep things interesting without overwhelming the senses. It’s sophisticated, timeless, and just plain beautiful.
