QUESTION 2: Is it worth using any special bathroom paint? The
ordinary gloss paint used before is not mould stained or anything
like that but it would be nice if the whiteness could be retained for
as long as possible.

Whilst it is not specifically bathroom paint, I have used water based paint
in our bathroom as it tends to yellow less.
For a reason I am not clear on, oil based paints seem to yellow in low light
situations (which many bathrooms seem to be).

Be warned, water based paint is not as easy to use/tends to show up brush
strokes more than the alternatives.
