How To Get Rid Of Mould In Shower And Prevent It Returning

Written by Mark Peers | 11-Mar-2026 10:00:00

Mould in the shower is one of the most persistent and frustrating bathroom problems faced by homeowners, landlords, and property managers across the UK. It looks unpleasant, it smells musty, and no matter how often you clean it, it keeps coming back. If you're searching for how to get rid of mould in the shower effectively and for the long term this guide covers everything you need to know.

Why Does Mould Keep Coming Back?

Before tackling how to get rid of mould in shower, it helps to understand why it develops in the first place. Shower mould thrives in warm, damp environments with poor ventilation. Every time you shower, steam and moisture settle on surfaces, and if it isn't able to evaporate quickly, it creates ideal conditions for mould spores to settle and grow.

In traditional tiled showers, the situation is made worse by grout lines and mastic sealant. These porous, jointed materials trap moisture and organic matter, giving mould the perfect foothold. Even after a thorough clean, spores embedded deep in grout can reemerge within days or weeks.

How To Get Rid Of Mould in Shower: Step By Step

For existing mould, prompt and thorough cleaning is essential. Here's an effective approach:

1. Protect Yourself First

Wear rubber gloves and a face mask before you begin. Mould spores can irritate the respiratory system, so good ventilation is important, open a window and switch on the extractor fan.

2. Choose Your Cleaning Solution

Several options are effective for how to get rid of mould in shower surfaces:

  • A diluted bleach solution (one part bleach to four parts water) is highly effective on stubborn mould in grout and silicone.
  • White vinegar applied undiluted is a natural, less harsh alternative that kills most mould species.
  • Purposemade mould and mildew bathroom sprays are convenient and widely available.

3. Apply and Dwell

Apply your chosen solution generously to affected areas, grout lines, silicone seals, corners, and the shower tray. Allow it to dwell for at least 10 to 15 minutes to penetrate the surface.

4. Scrub Thoroughly

Use a stiff bristled brush on grout lines and corners. For smooth surfaces such as glass or trays, a non-scratch sponge is more appropriate to avoid damage.

5. Rinse and Dry

Rinse away all cleaning residue thoroughly. Then dry the area as completely as possible using a towel or squeegee, and leave ventilation running. Moisture left on surfaces accelerates mould regrowth.

How to Prevent Mould Returning?

Knowing how to get rid of mould in the shower is only half the battle. Prevention is equally important:

  • Ventilate effectively: Use an extractor fan during and after every shower, and open a window where possible to reduce steam buildup.
  • Wipe down after every use: A quick squeegee of the walls and door after each shower dramatically reduces the moisture available for mould growth.
  • Clean regularly: Use an antimould bathroom spray on joints and corners a few times a week as a preventative measure.
  • Check for leaks: Hidden leaks behind walls or under trays create persistent damp that accelerates mould growth. Ensure you address these promptly.

When Cleaning Isn't Enough

For deepset or recurring mould in silicone or grout, no amount of cleaning will produce a permanent result. The mould is growing from within the material itself, not just on the surface. In these cases, the affected sealant or grout needs to be physically removed and replaced with a labour-intensive job that still won't last indefinitely. If you find yourself repeatedly asking how to get rid of mould in the shower because the problem keeps returning, the real answer may be that your shower's design is the problem.
