Our house has a raised corner shower stall in the downstairs bathroom. Just by doing a quick search and going off of looks, I'm pretty sure it's this model:
The floor in the shower has these stick on leaves that covered the majority of it and in the last couple days started to peel off. I've noticed before that the floor feels soft in places and sometimes almost has the sound of creaking wood in others. My original guess was that maybe the base was even framed with 2x4s and filled between. This is what the base looks/feels like. The blue circle is the drain. The brown lines feel like possible the supports as they are were it'll creak, but has the most strength. The areas between the lines are were the floor feels "squishy"/has some give to it. It was most likely installed in like 2006/2007 when the home was renovated, so now I'm almost guessing it might feel that way over water leaking into the base.. but I'm not sure of anything on it.
Originally I thought it was maybe just made to feel soft, but now that the leaves have started to peel off, we see that it appears to have cracked/been cracking before and the owners attempted to patch it with some sort of square white tape? I've marked them in the picture below with the black line around them. I'm not sure that it's leaking and I haven't removed all of the leaves yet to see the rest, but based on the feel and sounds of the base.. I believe there is an issue and I don't know that I trust that tape to be holding out water. What options do I have here to possibly stop any future cracking or water from leaking? Does anyone know why the shower would be making these noises/feel soft, is it accurate to blame water damage? Preferably I'd like to apply some sort of whole-coverage on to the base rather than continuing on with patches here and there.
