Can you plaster over tiles?
This depends on adhesion, system and future moisture load. Leaving tiles is not a general guarantee for a suitable substrate.

See the finish in detail.
What should you check first?
First check that the tiles and their substrate are secure enough. A new layer on top of loose tiles does not solve the problem. Also report cracks, moisture spots and the space in which the wall is located. The performer must assess the entire existing structure.
How does this affect your choice?
In a bathroom the chosen finish should be suitable for the concrete zone. Direct water contact requires attention to complete system construction and connections. A new decorative top layer is not in itself an explanation of waterproofness. Ask who performs the sealing and transition to plumbing.
Planning the next step
Compare maintaining and removing on the basis of the complete work. Leaving tiles can affect layer thickness, window frames and connections. Ask for a well-founded choice and record what happens to the existing tiles. Let the product requirements be part of that review.
Practical checklist
- Check loose tiles
- Report moisture load
- Discuss the layer thickness
- Capture system buildup

More advice for your project
The tile wall shall be assessed as a substrate
Finishing over tiles can only be done with a suitable substrate and system structure. Separate tiles, contamination, joints and moisture load deserve attention. A adhesion primer is not a solution for a tile that is not securely fixed.
Discuss these points for your home
- Report hollow or loose sounding parts for review.
- Please indicate if it is a wet area.
- Discuss the complete construction up to and including the final layer.
