4 Inch (100mm) Fans
Generally bathroom extractor fans are available in two sizes 4 inch (100mm) and 6 inch (150mm). Consequently a 4 inch bathroom fan will be large enough to cope in a normal sized family bathroom. Maybe if you have a bathroom with no ventilation, North facing or particularly cold you may require a more powerful one.
