How to block off a window?

[Makhaira]

Ok, so this is linked to my thread on redoing the bathroom. At the moment, there's a small window smack where I will put the shower enclosure. I'm intending to block it off, but want to make sure I won't run foul of damp/cold patches etc.

The window is a double glazed PVC unit with a vent.
The wall is a cavity insulated exterior wall, with dry lining.

My initial plan was just to leave the vent open, and cover the window opening with a piece of waterproof plasterboard, probably held in place by metal stud partition framework.

Any thoughts on the merits or pitfalls of this?

Cheers.

The other reason for not bricking it up macca (which I should have mentioned) was to ensure that the outside of the house looks unchanged - i.e. keep the window in.

My other option would be to modify the window sill so it sloped possibly, and then it wouldn't matter if shower spray made it onto the area.

What's your background btw macca? You're a regular feature in the DIY bit! A fellow workshop dweller at the weekends?

I'm only 50% manly then, I have no bowie knife!

Ahh, gotcha. In that case I'll go the tiling route, I'd rather do a proper job slightly differently than a bodge job exactly how I'd like it! Cheers.
