Dear forum,

I hope this is the right section for my question. I bought a condominium and hired a plumber to install a 3cm (1¼ inch) deep, 90x90cm (35x35 inch) shower tray. I discussed this with him before the screed was laid. He planned to place a board to leave space in the screed so the tray could be recessed. Now it turns out this was forgotten. The tiler says it won’t work and that the tray will stick out by 1.5cm (⅝ inch).

My question: it would now be necessary to remove an area of 90x90cm (35x35 inch), minus the 30x30cm (12x12 inch) hole for the drain, at a depth of 2cm (¾ inch). Do I have a chance? Removing the material with a chisel probably won’t work, or can this be done with a milling machine?

Thanks in advance.
Good luck, Frank

Hello Frank, is there underfloor heating installed in the shower area? That needs to be taken into account when removing the floor!
Then you could use a cutoff saw to score a groove all around your "hole" and try to chip away down to the insulation foam (the plumber should really handle this...).

No compromises, or you'll be annoyed for years.

Good luck

Hello Jens,
yes, there is underfloor heating installed, I think about 2cm (1 inch) will need to be removed. The plumber is definitely responsible for this. Since I have had legal disputes before, I will probably have to do the work myself if necessary.
I was also thinking maybe cutting grooves with an angle grinder + stone disc and then carefully chiseling out the strips from the sides?
Good luck, Frank

...that should work, is it anhydrite screed? It is usually quite thin... Check how thick it is planned to be. Are you sure that 2cm (1 inch) is enough?

Good luck

I’m not sure if it’s anhydrite screed. This is a shower tray from Hoesch that is 30mm (1.2 inches) thick. The tiles with adhesive will be 15mm (0.6 inches), plus some silicone under the tray. I think 20mm (0.8 inches) will be enough.

Good luck, Frank

You are not supposed to start a legal dispute with him, but rather ask him to fix the issue and fulfill his contract.
If you start working on the screed yourself, you might forfeit more warranty than you realize.
