Varnishing wood after water based paint/stain - Drying time?

[chris10000001]

Bit of a newbie here...

I am making a big bathroom shelving unit with cheap planed pine from wickes.
All going well so far...

To give the pine a bit of character I added a white tint/stain.
I am using a mix of 25% water based white satin & 75% tapwater

I now have a nice scandinvian whitewashed pine look

Question.. Next step is to varnish the whole thing to seal it for bathroom usage (using Ronseal Water based Varnish)

How long should I leave it before varnishing?
Since I have painted/stained the wood with a very watery whitewash I worry about sealing in too much moisture...

4 hours? 12 hours? 24 hours drying? - I Really need to finish up as our Bathroom and Kitchen are unusable during the build process

(I have a powerful dehumidifier if that helps...)

Water based? At least 12 hours, 24 hours to be on the safe side. Often turns milky blue/white when applied and clears as it sets

Thanks for the advice.
I applied 3 coats on over two days, resulting in a finish that is showing no problems after 3 months in the bathroom.
