Bathroom Extractor Fan Height

I was asked to give some advice today by a neighbour who wanted to install an Extractor fan in a new ensuite bathroom (which used to be a small office).

The room is going to have a bath but no shower, a toilet and a sink. There is no void over the ceiling as it is an extension built into. A bathroom vent fan is necessary to remove excess moisture from the room during baths and showers.

Ceiling Height Considerations Mount your fan 8. An effective bathroom fan should completely refresh the air in a bathroom 8 times in an hour, or just about once every 7.5 minutes. Look for a fan with a CFM that can accommodate the bathroom size at that rate.

Use this calculator to figure out the correct number of CFM needed for your bath fan. Bathroom Length (ft) x Bathroom Width (ft) x Bathroom Height (ft) x 0.13 = Minimum CFM needed. Extractor fans installed within zone 1 must be at least IPX4.

Extractor fans installed within zone 1 must be fitted with 12v SELV motors with the SELV transformers and isolators fitted outside of zone 0, 1 & 2. Zone 2 For a bathroom is the same height as zone 1 (2.25m) extended to 0.6m around the bath. A well-placed extractor fan is essential for maintaining a fresh, mold-free bathroom environment by efficiently removing moisture and odors.
