An inline bathroom extractor fan is a type of fan that is installed in the ductwork rather than directly in the bathroom ceiling or wall. It is typically used in larger bathrooms or bathrooms that have complex layouts.

Overall, an inline bathroom extractor fan can be a good choice in situations where a standard bathroom extractor fan may not provide sufficient ventilation or where noise reduction is a concern. It's recommended to consult with a qualified electrician or bathroom contractor to determine if an inline bathroom extractor fan is the best option for your specific needs.
