I own a 20 year old home that has a leaky shower pan. It apparently has been leaking for some time prior to my purchase of the home. You can see weak spots in the dry wall were the previous owns tried to cover the problem. I've had to tear out the entire wall in the shower. I'm not so concerned with the retiling of the wall as I am with the rebuilding of the shower pan. I've talked with several contractors and they say that adding the mesh wire is not a neccesary part anymore. Please, if you can tell me of a good resource to help guide me in this process. I've looked every where for some step by step photos or vides and have come up short. Thank you.
