I've decided to paint. What I had originally thought was a gaudy awful eggshell white flat paint on the the walls of the ENTIRE house was ACTUALLY PRIMER. I've painted (priming first of course) the main living areas. I'm now on to the bathrooms.
My conundrum is this: Do I / SHOULD I use a latex primer or mildew killing primer? This is the spare bathroom so it doesn't get a lot of shower usage per say. It doesn't have mildew that see; however I know Kilz has a mildew killing primer and wondered if "an ounce of prevention…" would be fitting. The primer in there now seems to have held up rather well. However, I don't want to put really nice paint (for bathrooms of course) on the walls only to have it begin to deteriorate in a few months or worse – when my first guest showers and water splashes somewhere.

I wouldn't worry about mildew resistance primer. Since the walls are already primed, what I would do is buy a semi-gloss latex paint. The semi-gloss will resist the water penetrating it and you shouldn't have to worry about mildew.
