Placing new Shower wall next to existing tile, Bad?
I am wanting to replace my tub/shower . It is an old tub and there is tile for the walls. The tiles are falling off and I want/need to replace. I was told by one of the estimators that where the new bath walls will meet the existing tiles, the existing tiles will soon just start to fall off the the others will follow. They will not do the job unless all the tiles touching will need to go. They would not give a quote with out that work. I asked the other estimators about this and they told me that the they put a strip there to stop that from happening. My question is will the tiles start falling off, or not? Has anybody been through this? The picture with the red line shows where the cut will be for the new shower wall and the existing tile.
