bathtub leaks, drips down to floor below
For the past few years, whenever I take a shower in my shower, there's a puddle outside the tub on the floor. Sometimes, water will start dripping from the ceiling directly below the tub. I'm just wondering what is causing this. I've noticed that the tiles all around my shower knobs appear to be loose, and don't have any sealant between the tiles. Could the water be coming from there? I've taken some photos to help show the problem.
Basically, I'm just wondering if all this water is coming from in between those tiles, or if one of the pipes is leaking behind the wall. I don't know much about home repair, but I could probably add sealant between the tiles and see if that fixes it. If it's a pipe that's bad, I'd probably have to hire someone to come fix it. Thanks in advance for any advice
