When it comes to renovations, bathrooms are one of the most exciting spaces to transform – but also one of the most challenging. They’re high-use, high-investment rooms where every decision matters, from the layout to the tiniest detail like where you’ll hang the hand towel.
Without a clear design plan, it’s all too easy to make choices that feel good in the moment but lead to regret later. To help you avoid the overwhelm, we’ve pulled together the most common mistakes we see and how to avoid them, so you can transform your bathroom into a cohesive, functional, and timeless space.
Mistake 1: Ignoring Functionality in the Layout
The foundation of any bathroom is its layout. Overlooking this step is one of the biggest errors renovators make. Layout oversights like tight shower recesses, clashing door swings, or a lack of privacy around the toilet can undermine your daily experience.
Think about how you’ll actually use the space day to day. Is there enough clearance around the toilet so it doesn’t feel cramped? Is there wall space for towel rails within easy reach of the shower? Can the vanity accommodate your storage needs and power points where you need them? These are the details that elevate a bathroom from frustrating to functional.
The fix: Start with functionality before finishes. Consider flow, privacy and future-proofing – whether that’s kids growing up, guests staying over, or your own needs in years to come. A well-considered layout makes every other design decision easier.
Pro tip: Always check clearances – you’ll thank yourself when you’re not bumping into doors or squeezing past the vanity to get to the shower.
Mistake 2: Mixing Too Many Styles or Finishes
It’s easy to fall in love with a tile here, a tap there, and a light you spotted online… only to end up with a bathroom that feels disjointed. A mix of competing styles and finishes can quickly make the space feel busy and unresolved.
Professional designers curate palettes with intention. We usually start with one anchor material – like a feature tile or timber vanity – and then layer complementary finishes around it. That might be a neutral tile, a complementary metal finish, and a paint colour that ties everything together. Three to four considered finishes will always feel calmer than eight competing ones.
The fix: Choose a clear style direction and work with a considered palette of finishes and materials. This creates a sense of flow and balance, while still allowing for variety and interest.
Pro tip: Start with one hero element – like a statement tile or bold vanity – and let that guide the rest of your selections.
Mistake 3: Overlooking Lighting Layers
Too often, bathrooms rely on downlights or a central ceiling light. The result? A flat, impractical space where tasks like shaving or makeup are difficult, and there’s no option to soften the mood when you want a spa-like experience.
A successful lighting scheme balances natural and artificial light. Natural light is wonderful, but bathrooms often need privacy, so for windows in your bathroom consider frosted glass, shutters or sheer curtains. From there, layer task lighting at the mirror for everyday routines, general lighting for brightness, and ambient lighting to set the mood.
One of our favourite practical touches is an LED strip under the vanity on a motion sensor or timer. It doubles as a soft night light, guiding the way without needing to switch on harsh overheads.
The fix: Layer your lighting. Combine task, general and ambient options to give your bathroom flexibility.
Pro tip: Think of your bathroom lighting the same way you would in a living room – different layers for different needs.
Mistake 4: Forgetting Key Measurements
Small details make a big difference. From the height of your taps to the spacing around your toilet, overlooking key dimensions can turn into daily frustrations that are expensive to fix later.
As a guide, allow at least 750-800mm clear space in front of a toilet so it doesn’t feel squeezed in. Vanity basins and taps should sit comfortably so you’re not splashing water everywhere – a spout height of around 150mm above the basin rim usually works well. For showers, an internal width of at least 900mm feels generous, with a glass screen to contain spray while keeping the look light and open.
The fix: Work with tried-and-tested measurements and check them against your household’s needs. Professional designers rely on these benchmarks to ensure comfort and functionality.
Pro tip: Get the builder to mark out key elements on site before committing. Standing in the space gives you confidence that proportions feel right.
Mistake 5: Rushing Selections
In the excitement of visiting showrooms, it’s tempting to make snap decisions. But picking tiles, taps and fittings in isolation can result in a bathroom that doesn’t feel harmonious. Worse still, it often leads to delays, stress and costly changes once work is underway.
Decision fatigue is real, especially when you’re faced with endless walls of tiles and tapware. The best way to avoid it is to pull all your selections together before you sign off. Create a “flat lay” with your tiles, paint swatches, stone and tapware side by side in natural light. This makes it much easier to spot clashes, balance textures, and confirm that everything works together.
The fix: Plan your selections as one complete scheme. Seeing the bigger picture avoids regrets and creates a bathroom that feels cohesive and well thought out.
Pro tip: Always gather and review samples of your tiles, paint colours and finishes together in natural light and in your bathroom space. You’ll instantly see what works (and what doesn’t).
