Repairing crack in solid surface shower pan
My parents had a contractor install a new shower a couple years ago with a custom made solid surface pan and tiled walls. They have just discovered that it leaks (to the living room ceiling below), due to a nearly invisible crack in the base.
They had the contractor come look at it and he's scratching his head saying he's never had that happen before. No solution has yet been proposed.
Any advice I can provide my parents on how this might be fixed?
