Thank you

Extractor fans must always directed outside hence yes you can install one under the stairs but you will need to find a place for the outlet and/or extend the flexible ducting until it reaches the outside

Syed · Answer

A toilet under the stairs extractor fan is typically fitted by a qualified electrician or a bathroom installer, as it involves electrical work and ventilation; in a terraced house the usual method is to core-drill through the external wall behind or adjacent to the toilet, fit a wall-mounted axial or centrifugal fan, and duct it directly outside with a rigid or insulated duct, external grille, and backdraft shutter, ensuring it complies with Building Regulations (Part F for ventilation and Part P for electrics), and if there is no direct external wall available, the alternative is to duct to the nearest outside wall or roof using appropriate ducting and access routes.

Hi you will need to run the ducting to an outside wall. This will mean running ducting surface mounted at ceiling height and then if required box in.
Not ideal but that would be the only option.

There are a couple of things you need to consider firstly being the PowerPoint to the extractor fan if there's not one already there
Secondly, The outlet of where they extracted is going to discharge

Mihai · Answer

An electrician usually fits the extractor fan. A builder may core drill the wall if needed.

You must vent it to outside air. You cannot vent into a void or loft.

In a terraced house you normally:

Core drill through an external wall if the toilet backs onto one.
Run rigid ducting to the nearest outside wall if it does not.
Box the ducting in under the stairs or ceiling.

If there is no direct wall access, you can duct up and out through the roof using a roof vent tile.

Expect £150 to £400 depending on duct length and drilling required.
