Bathrooms present unique challenges for interior decoration: persistent humidity, direct water splashes, temperature swings from hot showers, and limited ventilation conspire to destroy unsuitable paint within months. Our bathroom painting service specifies anti-condensation, mould-resistant coatings that maintain their appearance in these harsh conditions. From compact en-suites to spacious family bathrooms, we deliver finishes that look beautiful and perform reliably.
About Our Bathrooms Service
Painting a bathroom is not simply a matter of choosing a colour and applying emulsion. The microclimate inside a bathroom, particularly during and after a hot shower, creates conditions that would challenge even industrial coatings. Relative humidity can spike to near saturation, warm moisture condenses on cooler surfaces, and water droplets sit on painted walls for extended periods. Standard interior paints absorb this moisture, soften, and eventually blister or develop mould beneath the surface. The problem is compounded in London properties where bathrooms are often internal rooms with no natural ventilation, relying entirely on extractor fans that may be undersized or poorly maintained. At Mayfair Painters, we approach bathroom painting as a specialist task that demands specific products and careful preparation. We assess each bathroom individually, considering its ventilation, exposure to direct water contact, and any existing mould or damp issues. The coating system we specify addresses these conditions from the primer up, creating a durable, washable surface that resists mould growth and looks fresh for years rather than months.

Our Approach
Before any paint is applied, we address any underlying moisture problems. Mould is treated with fungicidal wash and allowed to dry completely. Areas where paint has previously failed are stripped back to stable substrate, and moisture-damaged plaster is repaired or replaced. We then apply a specialist bathroom primer that creates a moisture barrier between the wall and topcoat. The topcoats we use are specifically formulated for wet environments, containing fungicidal additives that actively resist mould colonisation. These paints are available in a full range of colours, so there is no need to compromise on aesthetics for the sake of performance. We pay particular attention to the ceiling, which is the surface most affected by rising steam, and to the area immediately around the bath or shower where direct splashing occurs. Ceilings in bathrooms often benefit from an anti-condensation coating that absorbs moisture during showers and releases it gradually as the room ventilates, preventing the dripping that stains conventional paint.
Materials & Brands
Our primary bathroom coatings include Dulux Trade Kitchen & Bathroom, Little Greene Intelligent Bathroom Matt, and Tikkurila Luja for the highest-performance requirements. For mould treatment, we use HG Mould Spray followed by Zinsser Mould Stop primer to eliminate existing growth and prevent recurrence. Anti-condensation ceiling paint from Thermilate or Dulux provides additional moisture management overhead. All products are low-VOC to ensure pleasant indoor air quality in typically small, enclosed bathroom spaces.
Property Considerations
Many period London properties have bathrooms created from former bedrooms or dressing rooms, often with original plaster walls and no damp-proof membrane behind the bath or shower. These installations require particularly careful coating specification to manage moisture that penetrates through gaps in tiling and sealant. Modern bathrooms with underfloor heating and good mechanical ventilation present fewer challenges but still benefit from moisture-resistant coatings for longevity. Compact en-suites and cloakrooms with minimal ventilation need the most robust paint systems available.
Why Choose Our Bathrooms Service
Mould Prevention
Fungicidal primers and topcoats actively resist mould growth, keeping your bathroom walls healthy and clean between redecorations.
Moisture Resilience
Specialist bathroom coatings withstand daily exposure to steam, splashing, and condensation without softening, blistering, or peeling.
Anti-Condensation Ceilings
Ceiling coatings that absorb and gradually release moisture prevent the unsightly dripping that plagues conventional bathroom paint.
Full Colour Range
Unlike basic bathroom paints limited to white, our specified products are available in thousands of colours for complete design freedom.
Our Bathrooms Process
Moisture Assessment
We survey the bathroom for existing mould, damp, ventilation adequacy, and previous paint failures to determine the right specification.
Mould Treatment & Preparation
Existing mould is treated and eliminated, failing paint is removed, and surfaces are cleaned, repaired, and primed for the topcoat.
Coating Application
Moisture-resistant topcoats are applied in multiple coats, with particular attention to the ceiling and areas of direct water exposure.
Final Check
We inspect every surface, remove all masking, and clean the bathroom so it is ready to use immediately.

We use moisture-resistant formulations such as Dulux Trade Bathroom+ or Little Greene Intelligent Eggshell. These paints contain anti-mould agents and withstand the high humidity of bathrooms without peeling or blistering.
We treat any existing mould with a biocidal wash, allow the surface to dry completely, and then apply a mould-resistant primer before topcoating. Good ventilation is also key, so we advise on extractor fan positioning if needed.
We carefully mask sanitary ware, taps, mirrors and shower screens to achieve clean lines. Where removing a fitting would give a better result — such as a wall-mounted cabinet — we will take it down and rehang it once the paint is dry.
A standard bathroom repaint takes one to two days. If mould treatment, filler repairs or a complete colour change is required, allow an extra day for preparation and an additional primer coat.
Tile paint can transform an outdated bathroom at a fraction of the cost of retiling. We use specialist epoxy-based tile paints that bond to ceramic and porcelain surfaces, providing a durable finish that resists steam and moisture.
Yes. We apply a stain-blocking primer to seal any existing watermarks, followed by two coats of anti-condensation paint. This special paint contains thermal microspheres that raise the surface temperature, reducing the condensation that causes staining.
