Plaster damp and damaged behind tiles in shower

I had a few loose tiles in the shower so decided to remove them, I’ve now taken quite a lot off and all the plaster is damp and soggy.

Should I remove, re-plaster, use a tanking kit and re tile?

Or instead could I mount waterproof back board onto the brick work and tile straight onto it?

Or is this both overkill? And should I just replaster and re tile?

I’ve since removed the tiles to the left also

Anyone? At a bit of a loss with the best option to go for to avoid it happening again.
I dunno, just guessing really, but I would say to do it properly you'd need to tank it. Looks very wet! Do you have another shower, so you can leave this to dry out and then assess it?

I can let it dry out yes. I was planning to rip it out and start again, just not sure if it plasterboard and tank or use a waterproof board like Kerdi board / Wedi board, as this says it doesn’t need tanking and can be tiled straight onto?

Not sure what’s best practice, or if there the same then what’s going to be easier?

remove them all, let it dry. If its solid, then prime, tank and tile. If its not solid, youll need to replace. I would suggest that it's 50/50.
By the time its dry enough to do anything with you could have ripped it off and done a proper job. It could turn out its gone too far anyway , in which case you've wasted all that time.
