If you’re updating your bathroom, choosing the right extractor fan might not be top of your list. But it should be. A poor choice can leave your bathroom steamy, smelly and damp. And once mould sets in, it’s tough to get rid of. The right ventilation will help keep your space fresh, dry and easy to maintain.

Extractor fans are designed to pull moist air out of the room and push it outside. Not into the roof cavity, but completely out of the house. This prevents steam from settling into walls and ceilings where it can cause damage. The size and power of the fan need to match the size of the room. A small ensuite won’t need as much grunt as a family bathroom, but even small spaces can develop big problems without good airflow.

There are a few types to choose from. Wall-mounted fans are a good fit for bathrooms with an external wall, while ceiling-mounted options are more common in central or upper-storey rooms. Some fans are ultra-quiet, with the motor mounted outside on the roof or wall. These are ideal if noise is a concern, like in an ensuite or near a bedroom. You can also find models that combine ventilation with lighting or heating, which can be handy for a tidy, all-in-one finish.

Placement is just as important as type. Fans should be positioned close to the main source of steam, like directly above the shower or bath. And it’s not just about turning it on during your shower. The fan should keep running for 10 to 15 minutes afterwards to properly clear the air. A timer switch can make this easier, especially for kids or guests who might forget.

Taking a little extra time to choose the right fan for your bathroom will pay off long after the renovation dust has settled.
