Condensation removal

[Gassaferob3]

hi all I,ve just remodelled my own bathroom and I think I've undersized my extractor fan.

My bathroom is 2.5 m square and its tiled wall to floor. My shower is 1.6m x 1m and its producing a lot of condensation.

Can someone please recommend a good - powerful extractor to remove the condensation. Currently it's in the ceiling in the shower enclosure. The enclosure is open at the top, there's about 30 cm from the top of the glass to the ceiling.

The fan is situated in the attic and pulls out of the shower below.

Any advice welcomed. Thanks

Before you do that, check if the current ducts are not kinked, blocked, full of water etc.
Some fans, including the one that Jackrae linked to (and which I have), can be wired for two or more speeds. Check if yours is wired for its highest speed.

Length of ducting?
Location and type of external grille?

You also need to have some way for the air that is extracted to be replaced - i.e. by a gap under the door, trickle vents etc. Without this, there is no circulation and the fan will not perform.

Does the fan overrun, or stop when you turn the light off. If you put a piece toilet paper over the fan whilst running, does it hold up against the fan, or drop down
