Bathroom specialist paint

[Koala2]

Is it essential to use this? Can't find one in the colour I like. Bathroom will have an extractor and also has a decent sized window.

No - I've never used anything other than emulsion in all my 26 yrs of home owning. Never been an issue.

You can probably get a bathroom paint mixed at a Dulux centre or in B&Q if you want it.

I have used both, but much prefer Matt emulsion, which has always been ok. Bathroom paint has a sheen to it, that I don't care for.
