Some of the signs of shower leakage are such as missing grout and tiles loosening. To combat this issue, you can opt for waterproofing services such as regrouting. It is a two-step process performed by specialists to restore tiled areas. The first step is to remove the hardened old grout between the tiles before applying the new layer. Once done, allow it to dry and clean the tiles. Your tiles should be as good as new now and shower leakage should not happen.
