Other than paint there is no viable way to resolve this that I can see. The extractor is above the shower in the 2nd warmest corner. We open the window when showering, leave the fan on for a good period after and keep the door open. The bath is in the cold corner so putting a heater in the cold corner would either require electrics or a bathroom refit. (Can you even put an electric heater above bath taps?!). Wall should have cavity wall insulation.
The only other thing I can think of is trying to add some more/better insulation in the joists above in the roof. But I'm skeptical that would make enough of an improvement in thermal efficiency.
I guess another extractor could be added in the cold corner. Or some kind of super extractor (but the current one is an inline jobbie not a little fan in the window).
Cheers.

(cold corner = 2 external walls North and West)
