Hey Sven, I can relate
When we moved into this house, there was white carpet on the floor in the bathroom. I'd never heard of white carpet in the bathroom, but here we are.
We were here six years when the toilet started to wobble. I teased my wife that one morning one of us would sit down, right into the basement.
Well, one evening, I pulled a corner up on that now not so white carpet, and it was one of those things that once you start, there's no going back.
The floor used to be 5/8 particle board, I took it out with a dustpan. Underneath that was four layers of wood that used to be glued together. Turns out the teasing was almost right
God bless the man that invented the sawzall.
Everything out to the studs and start over. In a house with only one bathroom.
Ever try to mash a bathroom remodel into a budget where there wasn't one?
Oh well, the joys of home ownership.
