Hello everyone,

I would like to install the following bathtub in a fully tiled bathroom:




In the manufacturer's installation manual, there is an illustration mentioning DIN18523:



What should I stick between the tile and the bathtub?
Is it purely for decoupling/sound insulation or for sealing?

I cannot use a classic bathtub sealing tape, where part of it is embedded with sealant, since the tiles are already on the wall.


Thank you very much and best regards
