ᐅ Missing waterproofing in bathrooms discovered after 16 years.

Hello dear forum members,

During the renovation of our basement, we discovered that the bathroom in the basement was missing waterproofing — both underneath and on the walls. This is now being properly installed.
At the same time, I am wondering what has been done about the bathrooms on the upper floor and the toilet on the ground floor.
Water would drip from one of the bathrooms on the upper floor into the hallway below after using the shower (cross-laminated timber ceiling). So I assume no waterproofing was applied there either. Only the silicone seal prevented water damage so far, but it was no longer perfect and we recently redid it.
Well, the house was built over 16 years ago with a general contractor who went bankrupt shortly after. So there is no warranty anymore.
What are our options now? Replace everything at our own cost, or is there any liability on the part of the tile installer, even though it was done through a general contractor? I still need to review the construction specifications in detail, but if waterproofing was state of the art back then, I don’t understand why it wasn’t applied here.
I really don’t want a legal dispute. We just don’t want to bear all the costs ourselves and want a proper installation so that no more water can penetrate the timber house.
Sorry if I have not provided enough details. I’m a bit overwhelmed at the moment and I’m happy to answer further questions. However, I would really appreciate avoiding any negative remarks, which I’m sure you understand.
Thanks in advance for all the helpful answers.
Good luck, Alena

I think the difference between a potentially faulty installation hidden under the shower and a toilet that is installed too high, which you use every day, should be clear to you. So, they cannot be compared.

Still, there is nothing that can be done after 16 years.
