We are rebuilding a shower that was originally two walls tile, glass door and half tile/half glass where
it met the tub. After our mold remediation and research into designs, it seems that fiberglass is the best option for keeping water away from my walls (other than a plumbing leak IN the wall). Your comments and recommendations would be appreciated. I will need a modular unit to get it in my home. How do the panels join/seal on these type models and what kind of maintenance is required (annual clean up and recaulk, etc).Do intallers need particular training to do this right (I will use builder subcontractor's)?
