No jets so no access panel.

The shower floor feels squishy.

Sub floor undersized or engineered. If left unattended eventually the entire flooring system under the bathroom will collapse. Normal amount of flex few prefabricated shower pans will feel as rock solid as a tiled shower base. Some bathtubs commonly develop soft spongy floors over time that lead to cracking and sometimes will cause leaks underneath the bathtub.

We noticed that our shower floor is sinking. Shower pans hollowness can be perceived as weakness and this is not necessarily the case. If there s a crawl space under the house you could brace it from underneath but that s not the right thing to do. Does your bathtub or shower have a crack in the floor.
