Top 15 Bathroom Paint Colours UK 2026 (Anti-Mould)

In a British bathroom the colour is the easy part. What decides whether the walls still look clean in three years is the paint system and the air: a washable, mould-protected finish on a sound surface, and an extractor that actually removes the steam. This guide lists fifteen bathroom colours with the makers' own descriptions, sets out what the three bathroom-specific finishes from Farrow & Ball, Dulux and Zinsser promise on their data sheets, and quotes the ventilation rate the Building Regulations set for a bathroom, because no paint survives a room that never dries out.

The best bathroom paint in the UK: the short answer

Pick the product before the shade. For designer colours, Farrow & Ball Modern Emulsion is the maker's own bathroom finish: 7% sheen, washable, "protected against mould" and described as "particularly perfect for moisture-prone kitchens and bathrooms". For a dedicated bathroom paint from the high street, Dulux Easycare Bathroom Soft Sheen is sold with a five-year mould protection claim and is for walls and ceilings only. For a bathroom that has already grown mould, Zinsser Perma-White Interior carries a five-year guarantee against mould and mildew on the paint film, when two coats are applied. Then make sure the extractor meets the Building Regulations rate of 15 litres per second for a bathroom, and choose a colour from the list below that suits the light.

The 15 best bathroom paint colours UK 2026

The list leans on Farrow & Ball because the maker publishes a description and a complementary white for each colour, which makes the choice verifiable; every one of these colours is available in Modern Emulsion. Quoted words are from the colour pages.

A pattern in the list: School House White is the complementary white for five of the colours, which makes it the natural ceiling and woodwork colour for a bathroom built around soft blues, blue-greys and green-greys. With the warm neutrals (Skimming Stone, Dimity, Cornforth White) the maker suggests Strong White, Pointing and Wevet respectively.

Choosing by light and size

North-facing or windowless. A cool grey or blue looks colder still in north light. Warm neutrals with a yellow or pink base keep the room comfortable: Dimity, Skimming Stone or Setting Plaster. Pigeon is the exception the maker itself names for "darker spaces", because a blue-grey with enough depth reads cosy rather than chilly.

Bright, south-facing. This is where the blues work: Light Blue is "peaceful and calming" in well lit rooms, Blue Gray and Pavilion Gray read clean and modern against white tile.

Small bathrooms and en-suites. One colour on walls and ceiling, or a shade apart, blurs the edges and makes the room feel bigger than a white ceiling over a coloured wall. Put the depth below: Green Smoke, Pigeon or Hague Blue on a bath panel or below a dado, a light colour above.

Period bathrooms. Blue Gray, Pigeon and Cromarty belong to the same muted family as the woodwork colours of a Victorian or Edwardian house; our period property interior colours guide covers the rest of the house.

Anti-mould paint systems: what the data sheets say

"Bathroom paint" covers three different products, and the data sheets show how they differ.

Read the limits as carefully as the claims. Zinsser's sheet says Perma-White "is not intended for application to floors or any surface subject to water immersion or prolonged contact with water including shower enclosures, saunas or steam rooms", and that where it is used above tile on shower walls you should "wait at least 24 hours before using shower". It also asks for all existing mould to be removed before painting and for bare plaster to be sealed with a primer first. The Dulux listing tells you to keep the room free of steam for 24 hours after the last coat. A mould-resistant paint protects its own film; it does not kill mould growing behind the surface, and it does not replace ventilation.

Ventilation first: what the Building Regulations require

Approved Document F, the statutory guidance on ventilation for dwellings in England, opens with the reason it exists: "Without adequate ventilation, mould and internal air pollution might become hazardous to health." It requires extract ventilation to the outside in kitchens, utility rooms, bathrooms and sanitary accommodation, and its Table 1.1 sets the minimum intermittent extract rate for a bathroom at 15 litres per second (30 for a utility room, 6 for a WC). Extract fans should be installed "as high as is practicable in the room" and at most 400 mm below the ceiling (HM Government, Approved Document F Volume 1, 2021 edition).

In practice that gives you a check before repainting. Hold a sheet of toilet paper to the fan grille while it runs: if it is not pulled firmly against it, the fan is not moving much air. A fan mounted low on the wall, or one whose duct runs a long way to the outside, often underperforms. If the ceiling corner above the shower is where the black spots keep coming back, the fault is airflow, and the right paint will only delay the return. When ventilation is sorted, a washable, mould-protected finish keeps the walls looking fresh between cleans.

Ceiling mould prevention: the zone most bathrooms fail

Steam rises and condenses on the coldest surface it meets, which in most bathrooms is the ceiling above the shower and the corner where the ceiling meets an outside wall. Three steps keep it clean: clean off any existing mould and let the surface dry fully; seal bare or patched plaster before painting, as the Zinsser sheet asks; and use the same mould-protected product on the ceiling as on the walls, in two full coats. A pure white ceiling shows the first spots quickly, which is useful as an early warning; a colour drenched across walls and ceiling hides them longer but makes the problem harder to spot.

Finish sheen: washable, not shiny

A bathroom wall needs to be wiped, not polished. Farrow & Ball's Modern Emulsion manages it at 7% sheen, which still reads as matt; Dulux's bathroom paint is a soft sheen; Zinsser offers eggshell, satin and semi-gloss. The higher the sheen, the easier the wipe and the more each dent and filler patch shows. Woodwork, bath panels and vanity units take an eggshell or satinwood suited to wood: the Dulux bathroom paint, for instance, is for plastered walls and ceilings only. The utility room colours guide and the conservatory paint guide apply the same logic to the other hard-working rooms.

Can you paint over bathroom tiles?

Painting tiles is a quick way to change a dated bathroom, but only away from direct water. Zinsser's data sheet says Perma-White "will adhere to gloss or semi-gloss paints, existing wallcoverings, ceramic tile and similar glossy surfaces without prior sanding", and asks that, where it is used above tile on shower walls, you "wait at least 24 hours before using shower" (Zinsser, Perma-White Interior TDS). The same sheet rules out "shower enclosures, saunas or steam rooms" and any surface "subject to water immersion or prolonged contact with water". In practice: tiles behind a basin or a toilet, or a tiled splashback, can be painted; the inside of a shower cubicle cannot, whatever the paint.

Preparation decides the result. Clean the tiles with a degreaser, rinse, let them dry fully, and repair any cracked grout first, because paint does not hold a loose joint. Two thin coats look better than one thick one, and a satin or semi-gloss finish is easier to keep clean on a tile surface than a matt one. Expect the grout lines to show through as a texture; that is the honest limit of painted tile.

Woodwork, bath panels and vanity units

The bathroom paints in this guide are for walls and ceilings: the Dulux listing says its Easycare Bathroom is "designed for plastered walls and ceilings only" and points to a different product for timber such as skirting boards. Wooden bath panels, boxing-in, window frames and vanity units take a wood finish, an eggshell or satinwood, which resists knocks and wipes clean. Painting the bath panel and vanity in a darker shade of the wall colour, such as Pigeon below Light Blue, or Green Smoke below Cromarty, ties the room together and hides scuffs at floor level. Let wood finishes harden fully before the room is used for showers, and keep the extractor running while they dry.

How much paint a bathroom needs

A typical family bathroom has 20 to 30 m² of paintable wall and ceiling once the tiles are subtracted. At up to 12 m² per litre (Modern Emulsion) or 13 m² per litre (Easycare Bathroom), two coats need 3.5 to 5 litres, so a 2.5 litre tin plus a second one, or a single 5 litre tin; Perma-White at about 10 m² per litre needs 4 to 6 litres for two coats. A small en-suite usually fits in one 2.5 litre tin. For what a decorator charges, see our interior decorator cost guide; for the room next door, the hallway paint colours guide uses the same washable finishes.
