Hello everyone,
We have been homeowners for just under four weeks and are completely renovating a house built in 1956.

In the bathroom, we have now encountered a “problem”:
Not only were multiple layers of wallpaper glued on top of each other in every room... no, in the bathroom, it was taken to the extreme. There are three (!) layers of tiles glued on top of each other.
To me, this is a total mess. I would like to remove all the tiles and start from scratch.

The contractors have already spent the entire day trying to remove the top layer of white tiles. Regarding the other two layers (brown and underneath red), they say the effort is not worth it for the following reasons:
- The tiles are glued so firmly that it would take days or weeks to completely remove them. They spent nearly one hour just removing a 10cm by 10cm (4 inches by 4 inches) section.
- The walls underneath are very uneven. After removal, at least a few centimeters (inches) of plaster would need to be reapplied, followed by drywall installation.
- The walls (especially around the door area, which is a non-load-bearing wall with a thickness of only 70mm (3 inches)) are quite old. The tiles apparently provide “extra” stability to the structure.

In short, they advised against full removal because the cost and benefit would not be proportional. They would essentially build a new layer on top of the old tiles and then tile the new ones over that.
Of course, the electrical wiring and plumbing would be renewed. This work would only be done fully in areas where all layers need to be removed.

I would really prefer to remove the tiles, but after today’s hard work, it only makes limited sense to me.

I’m interested in hearing your opinions and suggestions on the best way to proceed if the tiles remain in place.

They are rock solid. In the past, tiles were laid in a mortar bed, not with flexible adhesives, which did not exist back then. You can only remove these tiles with great effort, or simply build on top of them.

Because it looks completely wrong... similar to wallpaper. "I don’t bother scraping it off, I just keep wallpapering over it."
I know that tiles are often laid over existing tiles because it is cheaper and faster. But three layers???
Sometimes it is even advised against because tile adhesive doesn’t last forever, and with each additional layer of tiles the weight increases...

I’m just an amateur and Google shows both sides..

What would be the alternative?
