Keep Mould Out of Your Bathroom

Love Your Hot Showers? Make Sure You’re Not Inviting Mould In

There’s nothing better than a long, steamy shower—especially in the middle of a chilly Aussie winter. But all that warm, moist air hanging around your bathroom? That’s the perfect recipe for condensation—and eventually, mould.

When steam from your shower hits cold surfaces, it turns into water droplets, or condensation. That moisture can creep into grout lines, ceiling paint, and hidden corners. Over time, this feeds mould and mildew and can even lead to structural rot—a headache no one wants to deal with.

But don’t stress. With a few smart changes, you can boot condensation out the door and keep your bathroom clean, safe, and fresh.

How Do You Stop Mould from Taking Over?

The key is to get rid of that moist air before it has a chance to settle. The most effective way? Installing a proper extraction or ventilation fan.

These fans pull humid air out of your bathroom and send it somewhere safe, helping prevent condensation—and even nasty smells—from hanging around.

Where Should You Vent That Air?

Let’s break down the three main options, and what you need to consider:
Roof Vent

1. Through the Roof

This one’s common, but not always ideal. It involves ducting from the fan, up through the roof space, and out the top of your house. It gets the job done, but cutting a hole in your roof can be a risk if not done properly—and plenty of tradies would rather avoid it unless there’s no other choice.
external wall air vent

2. Through an External Wall

A much simpler and more popular option. If your bathroom backs onto an external wall, many fans can be fitted to exhaust directly through it—often without needing long ducting or major building work. Some models even plug into existing power points. Quick, clean, and effective.
Internal Wall Air Vent

3. Through an Internal Wall (with Ducting)

If your bathroom’s tucked away in the middle of the house, this might be the only choice. It involves ducting the fan through the ceiling or wall cavity to an external point, like the roof or side wall. Keep the ducting as short and straight as possible to reduce energy loss, airflow restrictions, and leak risks.

Final Tip: Keep Your Bathroom Breathing

Aside from installing a fan, here are a few quick wins:
  • Crack open a window during and after your shower.
  • Leave the bathroom door open once you’re done to let air flow through.
  • Wipe down wet surfaces to help them dry faster.
