A great bathroom isn’t just about looks, it’s about how it feels. With the right bathroom design choices, they can balance style, comfort, and functionality in ways that enhance your daily life.
We spoke with Magdalena Gruszczynska, founder of Supremati Interiors, whose thoughtful, detail-driven approach to design has transformed countless homes. She shares her expert advice on how to turn a bathroom into a beautifully balanced space.
How to Plan Your Bathroom Layout: Key Considerations
Assessing space and layout
Before a single tile is chosen or tap installed, every exceptional bathroom design begins with a question: How will this space be used?
From clients desiring a dual bath-and-shower configuration, to those prioritising storage for linens, robes, and even integrated laundry solutions, each brief is unique. Some seek double vanities for “his and hers” routines, while others are adamant about incorporating Toto smart toilets or classic bidets. Understanding these differences at the outset enables designers to sculpt a layout that flows with daily habits.
When reconfiguring a home, designers often have the liberty to reshape bathroom design dimensions. But in most cases, fixed walls mean every inch counts. Accurate measurements and scaled planning, mapping out the bath, shower, WC, vanity, towel warmers, and more, are critical to prevent overcrowding and to ensure ergonomic design.
Pro Tip: Position the vanity or the bath opposite the door to create a polished first impression, rather than exposing the toilet or shower immediately. Also, ensure the WC is within six metres of the soil stack to maintain proper drainage and avoid future plumbing issues.
Functionality vs aesthetics
Designing a beautiful bathroom that functions seamlessly is an art in itself.
With today’s vast array of sanitaryware, finishes, and lighting options, there’s no need to compromise, bathroom design can marry luxury and practicality.
Tailoring a bathroom design to those who use it is key. For example, tall individuals may benefit from vanities installed at 90–92 cm and larger WC models. Even thoughtful details like the depth of a vanity beneath a wall-mounted cabinet can prevent uncomfortable mishaps, such as bumping your head while leaning in to wash your face.
Every decision, from layout to lighting should work in harmony with the user’s needs and scale.
Budgeting and timelines
A bathroom redesign isn’t just about taste; it’s about timing and budgeting too.
Confirm your investment range early, then finalise your layout before selecting fittings. Knowing your style preference, modern minimalism or classic opulence helps streamline choices and avoid costly changes mid-project.
Visiting showrooms can be a game-changer. Sitting in a bathtub, opening vanity drawers, seeing the finishes or testing the tap in real time can provide clarity and confidence in your selections.
Choosing the Right Fixtures and Fittings
Bathtubs and showers
Freestanding tubs, like those from Antonio Lupi or Drummonds, make stunning focal points – especially those in marble or stone. Built-in tubs, by contrast, offer seamless integration into tiled spaces, creating a more understated aesthetic.
Sink styles and vanity units
Options range from integrated basins in continuous marble to vessel sinks finished in 24k gold leaf, hammered brass, or mother-of-pearl. Whether built-in for practicality or freestanding as a statement piece, the right sink anchors the room’s identity in any bathroom design.
Toilet designs
Today’s market includes sleek, modern WCs in a variety of colours. Toto remains a popular brand across both contemporary and traditional bathroom design thanks to its intuitive features and luxurious comfort.
Maximising Storage in Small Bathrooms
Storage is the silent hero of smart bathroom design. In smaller spaces, opt for floor-standing vanities for added capacity. Wall-mounted mirrored cabinets above the sink conceal clutter while enhancing light. Hidden cisterns and full-height cabinetry above the toilet can cleverly exploit vertical space.
Colour Schemes and Materials That Work
Neutral and light-toned schemes, think warm greys, creamy whites, and soft taupes remain timeless. These palettes allow brass, chrome, or black fittings to shine while enhancing spatial perception. Natural stones like Carrara or Calacatta marble offer both luxury and luminosity, especially when used in large-format tiles or bespoke cut slabs.
Bathroom Lighting Design Tips
A well-lit bathroom doesn’t just flatter, it functions. The UK lighting regulations specify:
- Zone 0 (Inside bath/shower): IP67 (fully waterproof)
- Zone 1 (Above bath/shower): IP65 with RCD protection
- Zone 2 (60cm from water source): IP44 minimum
- General bathroom (Zone 3): IP44 recommended for all fixtures
Lighting Layers to Consider:
- Task Lighting: Recessed IP-rated downlights as essential for a well-lit bathroom. Vertical wall sconces on either side of a mirror reduce shadows and improve grooming precision.
- Accent Lighting: LEDs in niches, under vanities, or along window sills enhance mood and add drama.
- Night Lighting: Subtle motion-activated toilet lights and under-sink glows provide elegance and utility after dark.
Mistakes to Avoid When Designing a Bathroom
Ignoring ventilation
Without ventilation, moisture buildup leads to mould and damage. Sleek linear slot grilles or ceiling-integrated vents preserve aesthetics while promoting airflow.
Overcrowding the layout
Leave adequate clearance around each fixture. For example, allow at least 60 cm in front of the WC, and avoid placing features too close together. Wall-mounted fittings and sliding doors can help maximise usable space in your bathroom design.
Poor lighting choices
Select the right colour temperature:
- Warm White (2700K–3000K): Creates a cosy atmosphere – great for evening baths.
- Cool White (3500K–5000K): Better for shaving, grooming, or makeup application.
How Do You Make a Small Bathroom Luxurious?
Embrace high-end finishes in pale hues, such as white marble, soft golds, or creamy travertine. Metal accents in antique brass or brushed bronze offer rich contrast and a sense of refinement. Incorporating niches with ambient lighting, artisan hardware, and bespoke joinery can further elevate the space.
