Bathroom Colour Ideas: How to Choose the Perfect Palette

Getting Bathroom Colour Right Is More Complex Than It Seems

Bathroom colour selection is more technical than any other room. It's a small space; it's high humidity; it's artificial light; it's fixed elements you can't change unless you fork out a bit of money. Get it wrong and you have a tiny bathroom with the wrong feeling. Get it right and you could have a small, beautifully resolved ensuite of up to 4 m² that feels like a spa-like retreat.

Before looking at bathroom colour ideas, I ask my clients to do an audit of the elements that you can't change: what colour are the tiles? What is the finish on your tapware, e.g. chrome, brushed nickel, matt black? And then what is the tone of your vanity cabinets? You need to understand these elements before picking a wall colour because you don't want to paint a bathroom wall first and then try and match to the tiles and the vanity.

Another thing to think about is your bathroom natural lighting. A north-facing window looks very different under natural lighting during the day and at night with a 3000K downlight. I've also seen many people choose bathroom paint colour under store lighting in a very warm colour temperature environment. It's a very bad move to do your painting under store lighting as cool tones do not render correctly, so test paint colours on your walls at different times of the day.

Bathroom Colour Schemes You Should Be Aware Of

Once you have an idea of what elements are not changing in your bathroom, then you can start to determine which bathroom colour schemes will work. The most common bathroom colour schemes for Australian homes are white, soft greens, grey/blue and brown/earth tones.

White and off-whites are probably the most common colour schemes used in the bathroom. White works with almost any colour scheme and with every finish in the bathroom, be it chrome, brushed nickel, matt black or brushed gold. Look for whites in warm tone and light reflectance (LRV) of 85 or above so you can feel like you have more space. Dulux Vivid White or Taubmans Endurance White are good white choices for the bathroom.

Soft greens, or sage, are also the bathroom colour scheme of the last three years in Australia. They work really well with brushed nickel, chrome or matt black, and they're light enough so you won't be worried about them darkening. Dark greens can make your bathroom feel smaller, so they should be reserved for bigger bathrooms.

Charcoal and moody dark palettes — think Dulux Domino or Taubmans Night Sky — are genuinely stunning in bathrooms with good natural light and larger footprints, but they absorb light aggressively in small spaces. Use them as an accent wall behind the vanity rather than across all four walls if the room is under 6 m².

Sandy/brown or terracotta colour tones are also a fast-growing bathroom colour. You'll start seeing them in more bathrooms as people try to integrate them with timber elements, or warm tones like brushed brass or dusk bronze tapware.

Choosing the Right Bathroom Paint Colours: Finish, Moisture and Practicality

Deciding on the colour direction is the easiest bit. Selecting the right product to apply that colour is equally important — especially in a room as moist as a bathroom.

Ordinary interior paint will fail in a bathroom. Full stop. Bathrooms hold a constant level of moisture and a flat or matte interior paint lacking mould-resistant additives will show mildew within 12 months on a plasterboard wall. The NCC 2022 requires at least 25 L/s (NCC 2022, ABCB Housing Provisions, Part 10.8) of mechanical exhaust ventilation for windowless wet areas, but even a very well-ventilated bathroom is difficult for ordinary paints.

For bathroom paint colours, specify an interior bathroom acrylic paint product in either a satin or semi-gloss sheen. For most areas, a satin finish is what I recommend — it has a degree of light reflection that can help smaller rooms without looking clinical like a gloss finish. A semi-gloss is an excellent choice in areas around the basin and the shower, where splash-back is greatest. Never use a flat or matte finish on a bathroom wall.

The waterproofing specification outlined in AS 3740:2021 also influences the type of finish that is painted over. Walls within a shower enclosure must be waterproofed to at least 1800 mm (NCC 2022, ABCB Housing Provisions, Part 10.2) (AS 3740:2021) above the floor substrate before any finish is applied; polyurethane and acrylic membrane systems require a cure time of 24 to 48 hours before overcoating. That is work that has to be undertaken by a licensed waterproofer, not a handy homeowner.

When it comes to pricing, bathroom paint ideas span a wide range. Budget bathroom-grade paint runs $45–$55 per 4 L. Mid-range paint such as Dulux Bathroom is priced at $70–$85 per 4 L, and top-tier moisture-resistant paints are $100–$120 per 4 L. The top-tier paints come with longer mould-resistance warranties and if you have an open shower with a plasterboard ceiling, it is worth the investment.

Bringing Warmth In: Timber and Natural Tones as Colour Anchors

With the right type of paint selected, you then have to decide how the wall colour relates to the vanity unit or other built-in features — in particular where a timber or timber-look cabinet is being used.

A timber vanity is a warm colour anchor around which the colour scheme revolves. The vanity finish is often the key to the colour selection, not a secondary feature — wall colours are chosen to complement it, not compete with it.

A lighter timber such as oak or blonde goes extremely well with a warm white, a gentle sage green or even a dusty pink wall colour. A dark walnut vanity will need something of greater depth on the walls, such as a warm charcoal, a dark olive or even a darker terracotta.

Wooden bathroom vanities are available in two main constructions: a PVC-wrapped timber-look finish and a real timber veneer face on a high-quality plywood core. The PVC-wrapped option offers better value and a more moisture-resistant finish, whereas the real timber veneer is more authentic in look and feel. Aulic specialises in premium plywood timber vanity construction. Both construction types work beautifully against the right wall palette.

Note that NCC 2022 waterproofing requirements apply to walls around the vanity as well as shower areas. Check with your waterproofer about which wall faces need waterproofing membrane before painting, including the wall behind a vessel vanity and the wall face above a benchtop basin.

Warm metallic tapware finishes — brushed gold, brushed nickel, dusk bronze — work very well alongside timber cabinetry. Keeping the same finish across the towel rail, toilet roll holder and robe hooks is a minor discipline but the end result looks resolved rather than pieced-together. Note that installing heated towel rails requires a licensed electrician.

Pulling It All Together: Bathroom Paint Ideas for Every Budget

Now you have an understanding of how wall colour, paint type and vanity tone work together, it's time to think about which bathroom colour ideas make sense for your actual budget — and costs can vary enormously depending on how far you want to go.

The HIA Bathroom Renovation Cost Guide 2025 puts a small ensuite renovation at $10,000–$25,000 (HIA Bathroom Renovation Cost Guide 2025), but not every bathroom colour makeover needs to be a full renovation. Here is my thinking across three price points:

Under $200 — DIY paint only. A new coat of bathroom-grade satin paint in a considered colour will completely change a dated bathroom. Prep surfaces properly — sand back and prime all glossy surfaces before painting. If you don't prepare the surface, the paint will start to peel within months. This is about colour, not replacing product.

$200–$600 — paint plus new accessories. Adding a new towel rail, robe hook and toilet roll holder in a matching finish (matt black is the most common and easiest to match in this price range), plus a new wall colour, will make a big difference. Think about contrast and colour pairings — a dark wall colour with white bathroom accessories, or sage with brushed nickel.

$600+ — paint plus vanity or fixture replacement. Matching a new wall colour with a new wood bath vanity creates an entirely new bathroom experience. Both Lukka and Aulic offer woodgrain finishes in 600 mm units starting from around $400. At this level the full palette needs to come together — wall colour, vanity finish, tapware finish and mirror frame — as a considered set of parts.

On any budget, never pick bathroom colours in isolation. Always bring your tile sample, tapware finish card and vanity door to the paint colour store to confirm everything works together.
