The bathtub has no access. It is on the ground floor- opposide wall is block. I see smell dampness and I know I have SEE what's going on but I can't. I'd hate to take the entire job apart because the tile job looks very professional-and to be honest I can't afford it right now. We bought the house less than 2 years ago and the home inspection did not reveal this defect. Has anyone ever just cut an access door into the side of a fiberglass bathtub? I am thinking a 12inx 12in doorlike access. Help!
