Condition of Walls?

[garash]

Hi, We are having our Bathroom refitted and having had one guy round to give a quote who said he would tile over the old tiles (no he did not get the job !) I decided to eliminate this happening
again so I removed all the tiles myself. Most of them came off very easily with only some effort required to get the rest off. I have now had another guy in to look at the job and he said the walls would need plastering. I am inclined to disagree because; only some plaster work has come away, ie from the wall where the cabinet hung which was never tiled in the first place. We are talking a few mm here and there. He said about the old adhesive (whats left of it) needing to be scraped back. I am of the opinion that the new adhesive should, and would, rectify this. I think he is just trying to find make because it is a very small room 53 inches x 79 inches. I would welcome any advice.

Why not post a couple of pics? Or we have to guess what condition your walls are in?

Use a floor scraper to remove any outstanding remains of adhesive, and lightly knock off any obviously failing or hollow sounding skim finish.
Isolate and remove the shower unit and its backing.
Use a cementitious "thin set" powder adhesive.
No plastering would be needed - the thin set would fill in any patches.
