Thanks for lots of suggestions...
I am first going to try these to see if that makes any difference..

1. straighten the duct and fix opening around light well
2. Increase timer if I managed to find a way..
3. Keeping door open after use
4. Lowering shower curtain a bit at the top to get more air..??

If none of these make any difference then need to think about a more powerful fans...Thanks all, feedback much appreciated.
Hopefully this weekend, i can do this..

No harm in trying these things first. For 'fix opening', I presume you mean to remove the light fitting and have an uninterrupted inlet opening? I wouldn't even bother fitting a grill on to that as there's a fair chance you may wish to go larger; just have the open duct there for the moment, to see if your improvements work = max airflow.

If you can see the make and model of the fan, you can most likely find all the info you need about it on t'net.

Surely keeping the door open after use just allows the moisture to go elsewhere in the house?

Open the window will be your most effective.

For reasons I don't really understand the OP is resistant to window opening - but it is the cheapest and likely to be the most effective solution (other than not showering)

Totally agree.  His aversion to opening windows, as well as no heating, is a recipe for disaster, unless a super powerful extractor is installed

Interesting point about opening a window, and I don't know the answer.

Certainly, if there wasn't an extractor fitted, then a window should be opened to allow ventilation. But, since there is an extractor fitted, I wonder if opening a window will help? A draught coming in the window will cool the room further, and could cause more condensation. It could also disrupt the fan's effectiveness by blowing the 'steam' around the room, and not let the extractor do its job properly. And, it'll be chilly coming oot of the shower...

I think it might be best to either keep the window and door closed, or - if the door seals too well - leave the door just cracked open. With a closed door, most replacement air will - I think - come in at floor level, and this is probably ideal to allow the steamy air to be extracted out the ceiling.

As someone else has pointed out, it certainly wouldn't be good in many cases to open the door to a large degree, and the moist air could cause issues elsewhere in the house. 

But, I don't know.

To get an effective air change in room to need to open windows on opposite flanks. When there is any wind one side will be a windward side allowing air in and the lee side will allow air out. 
Letting cold air in can make the steam disappear as it condenses on to the walls quicker. If the fan is close to the window it can be mainly taking out some of the fresh air coming in.
If you stood outside you would see whether steam was coming out of the window or not. It it more likely to come out on the lee side.

The guy just needs a big fan that'll suck the bludy doors off.

In a previous house, we had a windowless ensuite shower room with a rubbish extractor that went into a bedroom with a window with a fanlight that was always open, and a bedroom door that was mostly closed on.the rest of the house. No damp issues

Our current spot with a windowless bathrooms +  rubbish extractor had ongoing mould issues until the cheap £20 extractors in the bathrooms were replaced with super powerful extractors (I bought the ones with the highest extraction rate) with humidstats at £150 each...  eliminating the mould issue.
