The Basics of Extractor Fan Placement in a Bathroom

Bathrooms are often the most humid rooms in a home and require adequate ventilation to prevent mould growth. Extractor fans are an essential part of this process, helping to reduce moisture levels and maintain good air quality. But where should you place your extractor fan for optimal performance?

Height: The ideal height for an extractor fan is between 2-2.5 metres from the floor level – any higher than this will mean that the air won’t be able to circulate effectively around the room. If possible, it’s best to install your fan at ceiling level or slightly lower if necessary.

Distance from Walls: It’s important not to position your extractor fan too close to walls or other objects in order for it to work properly – leaving a gap of at least 15cm is recommended so that there is enough space for airflow around all sides of the unit.

Ventilation Points: For maximum efficiency, try and ensure that there are no obstructions blocking any ventilation points on either side of the bathroom (e.g. windows). This will help keep air circulating freely throughout the room and also allow fresh air to replace stale odours quickly and easily when needed.

Power Rating: When selecting an extractor fan, make sure you choose one with a power rating suitable for its intended purpose – i.e., if you have a larger bathroom, then opt for something more powerful than what would be required in a smaller space like an en suite or cloakroom. This will ensure optimum performance regardless of size/shape/layout etc…

Noise Levels: Lastly, but perhaps most importantly, consider carefully where exactly you want your extractor fan placed within your bathroom before installation begins. Think about how much noise it may generate (if applicable), as well as the potential disruption caused by having cables running through ceilings and walls. All these factors can influence how effective the fan ultimately ends up being.

When it comes to extractor fan placement in a bathroom, there are certain key considerations to take into account. In the next section, we’ll look at where you should avoid placing your extractor fan for optimal performance and safety.

Key Takeaway: An extractor fan should be placed between 2-2.5 metres from the floor level, leaving a gap of at least 15cm to walls and other objects, with no obstructions blocking ventilation points. Choose one with a suitable power rating for its intended purpose and consider noise levels before installation.

Where Not to Place Your Extractor Fan

When it comes to installing an extractor fan in your bathroom, there are a few key mistakes you should avoid. One of the most common is placing the fan too close to the ceiling. This can be dangerous as it restricts air circulation and can cause moisture buildup on walls and ceilings. It also increases the risk of mould growth, which could lead to health problems for anyone using the bathroom.

Another mistake people make when installing an extractor fan is placing it too far away from the wall. This reduces its effectiveness as warm air needs to travel further before being extracted from your bathroom, leading to poor ventilation and humidity levels that remain high even after running your fan for long periods of time.

It’s important that you place your extractor fan at least 30cm away from any walls or other obstacles so that it can effectively draw out hot air without obstruction. If possible, try to position it near a window or other opening where warm air will naturally flow towards it – this will help ensure optimal performance with minimal effort required on your part.

Finally, make sure not to install an extractor fan directly above any electrical appliances such as hairdryers or straighteners, as this could cause them to overheat due to lack of airflow around them – potentially leading to fire hazards if left unchecked.

By avoiding these simple mistakes when positioning your extractor fan in a bathroom environment, you will be able to enjoy fresh air all year round without having to worry about potential safety risks associated with incorrect installation methods.

When it comes to installing an extractor fan, it’s important to be aware of the places where you should not place your fan. In the next section, we will discuss some tips for successfully and safely installing an extractor fan in your bathroom.

Key Takeaway: When installing an extractor fan in a bathroom, make sure to place it at least 30cm away from any walls or obstacles and not directly above electrical appliances. This will ensure optimal performance with minimal effort and reduce the risk of fire hazards.

Tips for Installing an Extractor Fan

It’s essential that you measure and mark out where your fan will go before drilling any holes. A template can be useful for this, as it ensures you have the correct measurements.

It’s also important to make sure your fan is placed at least 30cm away from walls or other surfaces so that air can circulate freely around it. This distance should increase if possible, depending on the size of your bathroom and the layout of furniture etc.

The height of your extractor fan should be between 2-2.5m above floor level, but this may vary depending on whether there are any obstructions, such as shelves or cabinets, in its way. If necessary, you may need to adjust its position slightly higher or lower than recommended in order for it to fit correctly into place without blocking anything else off in the room.

Choosing the right type of extractor fan is also key when installing one in a bathroom. Ensure that you select one with enough power (measured by CFM) for both ventilation and noise levels required by law, which varies from country to country. The size of your bathroom will determine how powerful a unit needs to be; larger bathrooms require more powerful fans than smaller ones do. Additionally, consider whether an inline ducted system would work better for your space rather than just a single wall-mounted unit; these are usually more effective at extracting steam and moisture from larger areas like bathrooms due to their greater airflow capacity compared with standard models.

Finally, always follow manufacturer instructions carefully when fitting an extractor fan. They provide detailed guidance about installation methods that must be adhered to closely to avoid damaging either yourself or your property during the installation process.

Key Takeaway: When installing an extractor fan in a bathroom, it’s important to place it at least 30cm away from walls and 2-2.5m above floor level; select one with enough power for both ventilation and noise levels; and follow the manufacturer’s instructions carefully.


Knowing where should an extractor fan be placed in a bathroom is key to achieving the best results. It’s important to keep the fan away from any water sources, such as showers or baths, and make sure it’s not too close to walls or furniture. Following these tips will help you get the most out of your new extractor fan and ensure that it operates at its peak performance level.
