Bathroom tiling

[AngelaWarrington]

Hi, we have been doing up our house but had a bathroom fitter in for that room. Some of the white tiles have discoloured- see photos of before (all same shade, same batch numbers etc), and see after with ‘darker’ white tiles behind shower fittings and lower down near tray. Is this a leak?
If so, can anyone advise on easiest and cheapest way to fix? Open to people contacting me with quotes if you are local to Warrington.
Thanks for looking and helping!
Angela

Do you know what adhesive has been used?

(I'll move this to a more suitable forum for now as it appears to be more advice related but if anybody does wish to contact the member to discuss visiting to repair then feel free to do so).

Just to add to the above, do you tend to find it dries out and the colour goes back to match the other tiles if you don't use the shower for a few days? Or is it always like that?

the grout does appear to look darker with in the darker shade of tiles ,that would suggest water ingress , but might just be the picture, I wouldn't have gone with that slither of tile over the shower tray , looks like a full tile to ceiling , so could have altered set out imo

Thank you. I think everything used was mapei but couldn’t be certain, and the guy who did our bathroom is now uncontactable.
It stays this colour now all the time, no difference even when we’ve been out of the house for a few days and shower has not been used.

if you have any spare tiles , I would remove one of the tiles and see if the walls are damp , is this your only bathroom, water may be getting through that seal around the shower tray

Yes got spare tiles, this is the only bathroom. Will have to do that I guess then find someone to refit some tiles etc.

just remove 1 tile for now , you should be able to remove the grout around 1 tile with a Stanley knife maybe . if its water ingress you may be able to pop the tile out without chipping another tile , good luck
