Condensation in Bathroom has been Reduced Since Lining with Wet wall

JohnSwift10

I replaced my bath with a shower cubicle and also had all the walls lined with wet wall as they were partially tiled plasterboard.

I also had a new toilet and cistern and new sink.

Preciously when I had a shower the walls were always covered in condensation and I usually had to use a window vac to remove the condensation, but the cistern was always became covered in condensation again even after wiping it down.

There was always a pool of water under the cistern in the winter even with the heating on and an extractor fan going most of the day.

Since then there is no longer any lasting condensation and the bathroom feels a lot warmer.

I don't know what 'wet wall' is, but if it's some plastic, then reduction of condensation on the walls doesn't surprise me. 

However, no way could this reduce condensation on the cistern.

Wet wall is wooden based laminated panels
Laminate - Wetwall
The reason that there is reduced condensation on the cistern is because it is smaller than the old cistern and also because the bathroom is now less humid and there is also a lot less condensation on the walls.

Hi JS.
Was ventilation improved too? An extractor fan installed or upgraded?
If not, then something doesn't add up here. 
A certain quantity of 'steam' will be produced during the course of a shower, and that has to go somewhere. You can 'keep' it in the air as invisible water vapour, but that requires energy - heat - and it will mean that the air will be very humid.
At some point, the air cannot hold it all, and it'll condense out on surfaces, beginning with the coldest. You've helped sort the walls - these are much better insulated by the use of these boards, so the fact that these are drier comes as no surprise. 
The cistern, however, unless it's made from plastic, or is twin-walled or insulated in some way, will be as cold as the previous one, and will also now be sitting in a far more humid 'wet' air, so I'd be expecting a lot more condensation forming on it.
Why this is seemingly not happening must have a rational reason, but cannot be because it's 'smaller'.
Possibilities:
You are venting the room more. Eg, a better extractor has been fitted. Or, as with me, the warm weather means I leave the bathroom window open all the time.
The ambient temp is still high, in which case you can expect the issue to return in winter.
The cistern is insulated.
You are having cooler showers 'cos it's summer.
You are having shorter showers.
In short, unless you make moves to remove the 'steam' being generated during a shower, it will come back to bite you. If you, for example, allow it to dissipate throughout your house, expect mouldy corners in rooms or the hallway, or the bathroom ceiling.
Other than that, happy new bathroom

Just to answer that point specifically, the reduced cond on the walls means that the water vapour is still in the air - it needs to go somewhere, and will 'look' for the next coldest surfaces in your house on which to condense instead.
Unless you ventilate it away.
Do you have a good extractor fitted? If so, please use it - especially as the temps fall.
