Choosing a colour scheme is a big decision, but blue bathrooms ideas never seem to go out of style – whether it’s bright and breezy powder blues or deep, luxurious navy.
Psychologically speaking, blue can evoke a cooling, calming feeling, which is perfect for a bathroom design where you want to de-stress after a busy day. As a bonus, you’ll also be right in line with Dulux’s Colour of the Year 2026.
To guide you through the design process, we’ve collated 12 beautiful blue bathrooms ideas below as a source of inspiration, interviewing experts on how to make this shade work and sharing practical installation advice.
1. Co-ordinate a blue bathtub with a matching vanity unit
Short on time? Choosing a ready-picked bathroom suite is the easiest way to inject a pop of blue into your scheme without having to think about it too much. Not only does it make the process quicker and stress-free, but you can also find them at some very affordable price points.
In the example above, Tavistock Bathrooms has coordinated the matt mineral blue units with a pretty patterned floor, carrying the black cabinet door handles through to the mirror and taps for a cohesive finish.
Interior designer Katie Malik says, "Matching a bath with cabinetry isn’t always as simple as picking the exact same shade, however. A uniform approach can feel flat in some instances, so it can be better to introduce subtle variations. For example, a deep navy bathtub could be paired with a softer, muted blue cabinet."

2. Choose a blue bathroom basin
Move over, white basins! Colourful sinks are where it's at, and what better way to embrace this trend than with a beautiful shade of blue?
In the example above, the blue-grey fixture from Whitebirk Sink Company looks classy and understated, providing an easy way to introduce some colour into your bathroom without having to repaint everything. Even if you decide to change your design later down the line, blue is a versatile colour that complements a wide range of shades.
As well as creating a beautiful focal point that can be coordinated with your tiles or other furniture pieces, this bathroom sink idea will do a better job of hiding everyday wear and tear than white sinks.

3. Pick pretty blue window treatments
Another way to bring your blue bathroom to life is by introducing a colourful window treatment, such as the pastel floral roller blinds in the photo above, which coordinate with the candle holder.
Victoria Robinson, style and trend expert at Hillarys, says, “Blue bathrooms are such a calming choice, and the right window treatment can really elevate that serene feel. I love using roller blinds in soft complementary tones or subtle patterns – they add texture without overwhelming the space.
"Faux wood Venetian blinds are another favourite because they bring a natural warmth that contrasts beautifully with cool blue hues. And if you want something timeless and practical, vinyl shutters are perfect. They’re moisture-resistant and add a lovely architectural detail that makes the window a real design feature.”

4. Make a blue bathtub the star of the show
Let your bathtub do the design heavy lifting by choosing a freestanding blue model as the focal point. In the example above, this elegant slipper bath is the main attraction, featuring a luxurious copper roll-top design.
Katie Malik says, "A blue bath is inherently a statement. The most important consideration is the mood you want to create: lighter blues, like sky blue, feel calm and serene, while deeper, inky blues feel dramatic and luxurious. The goal is harmony; your bath should complement the space, not compete with it.
"Neutral backgrounds, such as crisp white walls or natural materials like wood and stone, help the blue pop. And bathroom lighting is critical: natural light amplifies vibrancy, while softer artificial lighting creates a moody, intimate atmosphere."
Beautiful in design and practical in function, this copper tub excels at conducting heat, keeping your bathwater toasty for longer.
5. Choose bold blue tiling
If you're not one to shy away from bold designs, choose a patterned bathroom floor tile and carry it through to your shower enclosure, as shown in the photo above. Or, for a subtler approach, you could stick to a single colour.
Abbas Youssefi, managing director of Porcelain Superstore, says, "Running the same blue tiles into the shower helps the whole bathroom feel connected, rather than split into separate zones. It can also stop the shower area from standing out as a purely functional space and instead make it feel properly considered as part of the overall bathroom design.
"This approach works particularly well in smaller bathrooms, where fewer breaks in colour and material can make the space feel more open. Blue is well suited to wet areas, so using it consistently creates a calm, cohesive feel throughout the room."
Abbas Youssefi is the Managing Director of Porcelain Superstore, which offers a range of stylish floor and wall tiles.
6. Install a blue partition wall for extra privacy
Whether you want to zone your space into clear areas or add an extra level of privacy, you may want to consider building a partition wall in your blue bathroom, as shown in the photo above.
This can also work well as a storage solution if you like a minimalist look, hiding storage units and cabinets out of sight but still within easy reach – particularly effective in large bathrooms that have room for it.
If you’re concerned about the wall blocking light or making the space feel cramped, you could opt for a frosted glass partition, a half-wall, or a sliding screen to keep it feeling bright and open.
7. Choose funky panelling in your blue bathroom
Geometric tiles are a great way to add instant colour and personality to your space, but if you don't want the hassle of fitting tiles, bathroom panelling is a smart alternative.
“Geometric panelling is a fantastic way to add depth, texture and visual interest into a bathroom, whilst adding a fun, retro touch. They’re quicker and easier to install [than tiles] and cover large areas effortlessly; making them the perfect DIY job," says Summa Costandi, co-founder of Panels by Sofia.
If you decide to go ahead with a creative bathroom panelling idea, make sure it is waterproof or water-resistant to avoid dampness and mould problems. PVC or treated MDF are the most common materials.
“When working with bold colours and geometric patterns, it’s important to consider the proportions of your bathroom. In larger rooms, panelling across multiple walls can create a boutique, hotel-style aesthetic. In smaller spaces, use geometric panels as a feature, such as in the shower area, or behind the sink and mirror to add impact, without overwhelming the space."

8. Use soft pastels and floral prints for a cosy, cottage-like feel
By using pretty pastel hues and dainty floral prints, you can escape to the calming countryside without ever leaving your house.
Katie Malik says, "Muted, sophisticated pastels work best, creating contrast without overwhelming the blue bath. Mixing natural elements with modern finishes – for example, a rustic wood vanity paired with an elegant stone floor, adds balance and visual interest."
In the photo above, these gorgeous tiles by Original Style feature traditional English blossoms, complemented by delicate framed prints and fresh flowers.
9. Create a monochromatic blue bathroom
If you're fully committed to the idea of a blue bathroom, there's no better way to dive in than with a monochromatic design. The lights, the tub, the walls, the floor – the photo above shows how stunning it can look when you layer shades of blue on top of each other with intention.
Katie Malik says, "Texture, tone, and light are everything. Layering materials, glossy tiles, matt cabinetry, textured wallpaper, and plush rugs creates depth and coherence. Even within tiles, varying shapes and sizes can transform a space: mosaic tiles for a focal wall, large-format tiles for a sleek, modern feel.
"Tonal variation is also key. A dark, moody wall blue can be balanced with lighter blues on floors, ceilings, or accessories like towels or shower curtains. Adding art or a vibrant plant introduces another layer of colour, keeping the space dynamic without disrupting the monochromatic scheme."
10. Design an ombre blue feature wall
Add a unique spin to your blue bathroom idea by including an ombre feature wall that blends seamlessly into a freestanding bath.
To get the look above, Annie Sloan's son, Felix Sloan, used their Chalk Paint in Aubusson Blue on the top third of the wall, then a 50/50 mix with Provence on the middle section, and just Provence on the lower third and the bathtub.
You'll need one brush for each colour, plus a water sprayer, and to keep everything water-resistant, finish with their Matt Lacquer.

11. Go for half wallpaper, half panelling
By taking the half-panel, half-wallpaper approach, as seen in the example above by Bobbi Beck, you can break up the wall in an interesting way that works particularly well as a small bathroom idea.
James Bryant, founder of CutMy, says, "The panelling grounds the room and provides visual weight below, while wallpaper above draws the eye upward, making ceilings feel higher and the space more expansive.
"From a practical standpoint, lower walls take the most punishment – from cleaning products, water splashes, and daily contact. Panelling here means you can wipe down surfaces vigorously without worrying about scuffs, marks, or water damage, while the wallpaper above remains pristine and protected from moisture, staying in perfect condition for years."
12. Carry a blue bedroom scheme through to the ensuite
Blue is one of the best colours for a bedroom, and if yours is already painted in this scheme, why not carry it through to your adjoining ensuite to create a sense of flow? As a bonus, you can put leftover paint tins to good use and save on your bathroom renovation.
"Carrying the blue into an ensuite reinforces a visual connection between the two spaces, making them feel intentionally linked rather than separate. It also helps ensuites feel calmer and more integrated, especially where there are direct sightlines between the two rooms," says Abbas Youssefi.
"Don’t be afraid to mix up the tones – softer blues in the bedroom can be echoed with deeper or glossier blue tiles in the bathroom. Blue is an incredibly versatile colour, which means it can feel restful in the bedroom yet fresh and clean in a bathroom, making it an ideal colour to bridge both spaces."
“Blue is a timeless colour in the bathroom, and with Dulux’s Colour of the Year 2026 announcement, we’re expecting to see more blue shades throughout 2026, " concludes Summa Costandi.
