I have 6 tiles at the bottom of my shower stall that the grout has come loose. The home is only 6 years old and the caulk is still in good shape.
When the shower head is turned toward the tiles with the loose grout, the water leaks down to the basement.
When the shower head is turned away from that area there is no leaking of water.
Can the looe grout cause water to stream into the basement and how do I insert more grout to eliminate this problem?
