There are a large number of different bathroom extractor fan options available to you. You might decide to have an extractor fan fitted in a wall, or alternatively in a window. There are so many options to choose from that it can be confusing to know which one is right for you.

Spend time learning about the various different options available to you so that you can make an informed decision and choose the right fan for your bathroom. Many building codes require the use of a bathroom extractor fan in all bathrooms build after the change came into affect. It is also sensible to install bathroom extractor fans in existing bathrooms as it will help to improve the environment in that room.

1. Capacity

When choosing a bathroom extractor fan you will need to ensure that it is the right capacity for the size of room you are installing it in. To work this out you first need to measure the room in meters. Measure the length, width and height of the room. Multiply the length, width and height of the room together to work out the volume of your bathroom in cubic meters. The extractor fan will need to completely change the volume of air inside the room 3 times every hour. Simply multiply the volume by three to calculate the requirement.

An extractor fan should use a timer to carry on working for fifteen minutes after the switch has been turned off. This will ensure that all the moisture is removed from the room after having a shower.

2. In a Window

The extractor fan can easily be fitted into a window by cutting a small hole in the pane of glass. The extractor fan is then clamped over the hole. If you have a sash window then you will typically need to set stops to prevent the window from opening and blocking the fan.

3. Fitting above the Shower

The bathroom extractor fan can be fitted above the shower to extract any moisture in the air as quickly as possible. Fitting the extractor fan in the ceiling will require cutting a hole into the top of the ceiling and then running the duct through the crawl space. To do this you will probably need to go up into the attic or lift up the floor above if you're working on a ground floor bathroom. When fitting above the shower it's possible to route the ducting quite a long way until you get to an external room.

The external extractor fan can also be mounted under the soffit board if you prefer so that it doesn't need to actually be fixed through the wall.

4. Fitting in the Wall

The most common and easiest option for anyone fitting an extractor fan will be to fit it in an external wall of your house. This will make fitting the fan very easy because a hole cutter will simply be needed to cut through the wall. Then ducting can be fixed into place and then the extractor fan is fixed to the wall. This option will only be possible if your bathroom is built along an external wall.

Almost all bathroom extractor fans are identical and as they do not need to change the room as often they are less powerful than many kitchen extractor fan.
