I've noticed some wet spots on the basement carpet underneath our tiled shower on the ground floor. I had hoped it was from water getting out of the shower, but I did a flood test today by putting about an inch of water in the bottom, and it was raining in the basement through a weak point in the subfloor.
The house is about 20 years old, and the shower is likely of a similar age. There are some cracks in the sanded grout where the tiled floor meets the tiled wall, but I would have thought the vinyl shower pan should catch any water getting out through there.
At this point I'm contemplating ripping everything out and building the shower over myself. I figure any attempt to find the source of the leak would inevitably result in me cracking tiles, which would necessitate redoing all the tiling, and at that point I may as well strip everything out and build it the way I want, and do it well. Am I crazy to think this way? Is there an alternative way to repair the leak that I haven't considered and would be cheaper and/or faster?
