Bathroom Extraction Fan

Bathroom extraction fans are required for better ventilation. Condensation in a bathroom is very common, it is easy for mould to grow in the bathroom. A bathroom extraction fan will help in reducing the moisture in the air and increase the clean air levels. It also helps in eliminating odour as well as fumes.


Ventilation requirements for bathroom extractor fans according to Healthy Homes Standards are:

Installed AFTER 1 July 2019: The fan and all exhaust ducting must either have a diameter of at least 120mm OR the fan and all exhaust ducting must have an exhaust capacity of at least 25 litres per second. The fan must vent extracted air to outdoors. Continuously operating extractor fans that operate at a level of extraction below 25 litres per second, or do not have a fan and ducting diameter of at least 120mm, are not capable of providing the necessary level of moisture extraction during
a shower.

Installed BEFORE 1 July 2019: No minimum size or performance requirements but fans must be in a good working order and ventilate to outdoors. This means that the extractor fan must not vent extracted air into a roof space or other space. Any ducting must be connected, intact (i.e. without tears or holes) and installed so that exhaust air can flow freely through it (e.g. no unnecessary kinks or compressions). Any grills or filters must be unclogged.
