I had a look at the outside of the house and I don't appear to have any
eaves! Any advice on how I could vent the thing?

Tile vent might work then...

How easy is one of those to fit?

I'm thinking it may be easier to just replace the original wall mounted
one
with with a more slim line unit. The hole at the moment is approx 12cm
which
is just over inches. Looking at TLC Direct etc looks like most of the
fans
are around inch and they look a lot more slimline than this archaic
unit!

Might be OK - where is the fan in relation to the shower?

That's the problem, its diagonally opposite to the shower around 2 metres
away. I think its better to have one above the shower.
