Never trust the waterproofing behind the tile when the installer can’t even polish their exposed cuts.
Poor tile installation is usually a warning sign of what you can’t see. Bad layout, lippage, sloppy cuts, poor grout joints and unfinished edges should make you question the shower waterproofing behind it.
A properly built tile shower starts long before the tile goes up: correct substrate preparation, waterproofing, shower pan installation and flood testing matter just as much as the finished tile.
Pretty tile doesn’t fix bad waterproofing.
