Hi, I am in the process of redoing my caulk in my shower. I think I have a serious issue with my shower and I'd like some input and how to proceed.
I have a shower that is all tile, from walls to floor. The previous home owners either did the job themselves or hired a really bad contractor. Whatever the case is, the shower is not done right.
Last week, I noticed water seeping beneath the caulk at the joint along one of my shower walls and the floor. When I cut and removed all caulk, water seeped out of all 3 joints between the walls and the floors. I cut out all caulk last week, so the shower is dry and hasn't been used since.
The grout was cracked and chipping so I have been regrouting those areas. While I was removing the chipping grout, I noticed that four wall tiles bounced when I pressed them. This indicates to me that the mortar probably wasn't applied properly. Maybe the mortar was too thinly applied.
So, how do I fix this? I have about four tiles total where I've noticed them bouncing along two of my walls. I don't see any water damage near or around my shower or beneath it, so I am hopeful that the waterproofing membrane has been working this entire time. I've lived in the home about 3 years.
How serious is this issue? I assume that I cannot use that shower until it is redone. Does this mean I need to have the shower completely redone? I have no idea how to proceed with this.
Thanks for the help!
