Why Bathroom Exhaust Fans Are So Important

One of the most important rooms to keep cool during the hottest months of the summer is your bathroom. The heat, combined with the build-up of condensation after showers and baths, can cause the air in your bathroom not to flow properly, causing possible bacterial buildup, which can lead to mould growth. 

If you’re finding that the airflow inside your bathroom is non-existent and you’re starting to smell a musty odour, you must devise a solution to vent your bathroom properly. Particularly if you live with someone who has breathing difficulties or is immunocompromised. 

If you don’t have an exhaust fan, it might be time to consider doing bathroom renovations to have one installed. 

What is an Exhaust Fan? 

Exhaust fans operate by pulling air into them from the surrounding location. They aren’t so much used as a circulatory system but as an air purification system. They’re primarily used in at-home applications such as bathrooms. They make an ideal addition while renovating your bathroom by pulling air into them. They are most commonly used while the shower or bath is running to pull the steam into them, causing less condensation build-up. 

There are two different types of exhaust fans – you should consider each option when drawing up plans for your bathroom renovation. 

Axial Exhaust Fans 

Axial exhaust fans are the most common type of fan for simpler applications, and they may well find a place in your bathroom renovation. They operate by moving the air parallel to the fan’s axis, circulating it around the space, or moving it from one space to another. 

Centrifugal Exhaust Fans 

Centrifugal exhaust fans operate by sucking air in and spinning it around a disc, using the centrifugal force generated by the spinning disc to move the air to the fan’s outlet. They create high-pressure airflow and are often used in drying systems – like in your tumble dryer. 

Different Mounting Types of Exhaust Fans 

If you use a licensed Sydney bathroom renovation company, they will likely want to know how you plan to mount your exhaust fan. A few different options should be carefully considered before you start renovating your bathroom. They are the following: 

Wall Mounted Exhaust Fans 

If you’re looking for a quick option, then the wall-mounted exhaust fan is one of the best. It’s affixed to an external wall, allowing the air to pass freely through the fan. This may be your cheapest and best option for installing an exhaust fan. 

Roof-Mounted Exhaust Fans 

Like the wall-mounted exhaust fan, the roof-mounted exhaust fan pulls air from the room where it is installed and expels the air through a roof vent. This is a more complicated install and should only be done if your technician advises that wall-mounting fans aren’t possible. 

Inline Exhaust Fans 

This is one of the best options for poorly-ventilated rooms like the bathroom. An inline exhaust fan is mounted between ducts to help expel bad air from the environment. 

In general, most people will choose to have an exhaust fan mounted to the ceiling in their bathroom and air circulated via their central air circulation system. You should always consult a professional before attempting to do this yourself. Exhaust fan installations are complicated (some more than others) and should only be done by a professional in bathroom renovations. 

How Renovating Can Improve the Performance of Your Exhaust Fan 

If you have already installed an exhaust fan, one of the goals of bathroom renovations might be to get that puppy to function better. Things like underfloor heating and cooling and installing a small window – that you open slightly when showering or bathing – will help reduce the stress on your exhaust fan. Other options include exploring re-ducting your existing ventilation system to improve airflow.
