I bought this property a few months ago. The master bathroom has a tile shower. After the shower is used and the floor has dried, stepping on some of the tiles results in a "squish" noise, and a little water comes up through the grout.
You can see in the photo of the shower floor my (poor) re-grouting; there were some cracks in the grout near the drain and I had hoped replacing it would solve the problem. (It obviously didn't.)
What should I do next to diagnose & repair this weeping floor? We've been showering in the guest bathroom for long enough, I think.
Bonus question: how urgent is this?
