Concrete under Shower Pan after it's installed?
Looking to reinforce my fiberglass shower by putting a hole in the wall on the side and shoving concrete or somethng else under there. Any suggestions? Not cracked yet, but it' "giving." also- toilet squeaks when we sit on it, and it seems to be coming from the conical crome part that sits flush with the floor. The connection from the tank to the floor is rigid and we thing a flexible tube may alleviate this since it seems to be coming from the floor interface. Very annoying! Any help is appreciated.
