The shower floor feels squishy. Does your bathtub or shower have a crack in the floor. The master bathroom has a tile shower. There are no visible cracks and no water damage to the floor underneath it s over a second bathroom.

Not to mention i have to battle mildew growing on parts of the grout even though we wipe down the shower after every use and leave the fan on. This condition allows the floor to give slightly when you step.

If you are accustomed to a tiled shower base you will immediately sense the difference. If the sub floor is not strong enough to span the distance between the floor joist trusses or supporting beams then sponginess may occur. As an aside the caulking where the shower tub meets the floor looks like it needs to be replaced which is on the to do list but we don t shower in this bathroom and the tile that is squishy isn t next to this area.
