I’m having a bathroom refurb and as you can see from the images attached, within minutes of the old tiles being removed, it’s obvious the old plaster underneath will follow suit. Would you suggest removing all the tiles and the remaining (if any) plaster and then dot and dab plasterboard to refinish? Or any other suggestions. Large 120x60 porcelain tiles going up so a fair amount of weight hanging off the plasterboard. What’s everyone’s ideas to the best approach please. I’d ideally like to go with the dot and dab plasterboard technique for speed but this is my own house so don’t want a bodge job.
