Hello out there and thanks for reading this... I remodeled a bathroom in 2009 and I've developed 2 leaks unfortunately. The bathroom is on the second floor of a 2 floor condo and the leaks showed up in the kitchen below. From what I can tell, and after removing the sheetrock in the kitchen the leaks seem to be coming from both opposite ends of the shower perimeter walls (one under the hot/cold and faucet side and the other side where most of the shower water hits the wall). I'm noticing a lot of cracks around the perimeter of the shower floor and some in the corners where the walls meet. I tried to capture those in the pics attached. From what I remember all the seams were finished with grout (floor/wall, wall/wall). There is also a crack in the saddle which has been caulked and to me looks sealed well. I know this is really hard to diagnose and water can be coming from anywhere but seeking some troubleshooting advice please? One thing I did last night was I plugged the drain and filled the shower base so that the water came up about 1/2 inch on all the walls. It seemed like the base held the water and I didn't notice a difference in the dripping (maybe slightly but very hard to tell). I let that sit for maybe 2 hours and then unplugged the drain. Left overnight hoping things would dry out and I could do some caulking to see if that helps anything. This morning I noticed the dripping from the leaks were much more noticeable than last night and that was after not using the shower at all. I did use an adjacent bathroom shower but Im confident that's not leaking or creating this problem. Sorry for the long winded explanation but just looking for any troubleshooting advice I can get. To summarize:
1. 2 leaks seems to be coming from shower above kitchen.
2. Cracks around perimeter of floor (grout used prior)
3. Shower base seems to be holding water but maybe my test wasn't thorough enough.
If I try to now caulk the shower perimeter floor, can I just go over the grout that's in there or does that have to be removed?
On another note the shower pan was done with mud, rubber membrane (I forget the product name but the stuff that's made for that and ran up the walls about 8 inches.
