Quick Summary
To prevent mould in the shower, break the three conditions it needs: moisture, warmth and food. Run the extractor fan during and for 20 minutes after every shower, spread the curtain open, squeegee walls and glass, and choose storage that drains and dries rather than holding water.
- Mould grows when moisture, warmth and food such as soap scum and skin cells line up together.
- Run the extractor fan during the shower and for 20 minutes after.
- Pull the shower curtain fully closed after use so folds do not trap water.
- Wash fabric items on a cold, gentle cycle with minimal liquid detergent and air dry.
- Shake off excess water and let the caddy hang open with bottles spaced apart.

Step 1: Understand Why Mould Grows in Showers
Mould grows in showers because three conditions line up at once: moisture, warmth and food. Remove any one of them and growth slows or stops. That single idea is the foundation of every step in this guide to how to prevent mould in the shower.
The Three Conditions Mould Needs
Mould needs water, a surface to cling to, and organic matter to feed on. Soap scum, skin cells and dust all count as food. Warm, damp air keeps the cycle going.
Hemp is a natural material with its own resistance to mould, though resistance is not proof. It dries faster than plastic and does not trap water the way a solid caddy does. That is part of why we chose it for hemp's natural fibre properties.
Step 2: Use Bathroom Ventilation to Prevent Mould
Bathroom ventilation to prevent mould works best when air moves during and after every shower. Run the extractor fan after you finish, not just while the water runs. If you have a window, open it wide and leave the door ajar so damp air has somewhere to go.
- Run the fan during the shower and for 20 minutes after (Preventing condensation in your home)
- Open a window when the weather allows
- Leave the shower curtain spread open
- Wipe down walls and glass with a squeegee
- Keep the room warm enough to help moisture evaporate
A common mistake is switching the fan off the moment you step out. The room is still full of steam. Let the air clear.
A simple ventilation routine makes the biggest difference to keeping the shower dry.

Step 3: How to Prevent Mould on a Shower Curtain
To prevent mould on a shower curtain, keep it spread out and dry between uses. Pull it fully closed after a shower so folds do not trap water. Never bunch it against a wet wall.
Wash the curtain regularly rather than waiting for spots to appear. A simple routine beats a deep clean every few months. Check the hem and the bottom edge, where water collects most.
Watch out: leaving a wet curtain bunched in a corner is the fastest way to grow black spots along the folds. Once mould roots into the fabric, washing rarely removes the stain.
Step 4: How to Clean a Shower Curtain Properly
Cleaning a shower curtain properly means washing it before mould takes hold, not after. Follow the care label, use a gentle cycle and let it air dry fully.
For a fabric caddy made of hemp, the routine is similar. Learn how to clean a hemp fabric shower caddy with a cold machine wash, minimal liquid detergent and hang drying, plus a simple care schedule.
- Check the care label first
- Use a cold, gentle cycle
- Add minimal liquid detergent
- Skip harsh bleach on natural fabrics
- Hang to dry in open air
A common mistake is tumble drying on high heat. It can shrink fabric and weaken the weave.
Step 5: How to Keep Shower Caddy Dry
To keep a shower caddy dry, choose one that drains and dries rather than holding water.

Shake off excess water after each shower and let the caddy hang free. Space bottles apart so air reaches the fabric. If you are thinking about a considered, hardware-free setup, see this guide to hanging shower storage without drilling.
- Let the caddy hang open
- Space bottles so air can move
- Wash the caddy on a regular schedule

Frequently Asked Questions
How do I stop mould growing in my shower?
Stop mould by removing moisture after every shower. Squeegee walls, leave the curtain spread open, and run ventilation for at least twenty minutes. Fix leaks promptly and clean grout with a mild solution weekly. Keeping surfaces dry is the single most effective way to prevent mould in the shower.
Should I leave the shower curtain open or closed after showering?
Leave it open. Pull the curtain fully across the rail so folds dry out, rather than bunched together. This simple habit is key to how to prevent mould on a shower curtain, as it lets air circulate and stops damp patches forming.
How often should I clean a shower curtain to prevent mould?
Clean the curtain every two to four weeks. Machine wash fabric curtains on a gentle cycle with a mild detergent, or hand wash with warm water and a little bicarbonate of soda. For how to clean a shower curtain effectively, always dry it fully before hanging it back up.
Can hemp resist mould in a damp bathroom?
Hemp has natural mould resistance, but that is resistance, not proof. Hang it to dry between showers to help it stay drier. A hemp hanging organiser, such as the natural storage solution for the shower from Shwelf, stays drier because it hangs in the shower and lets air move through the weave.
Mould in the shower is a moisture problem, not a cleaning problem. Fix the airflow, dry your surfaces, and choose storage that lets water drain away. Shwelf makes that last step simple with a hemp organiser that hangs in the shower, resists mould naturally, and needs no hardware. Get started with Shwelf and give your bathroom a calmer, drier routine.
