Firming up Tub
New log home self build, put in a fiberglass tub and surround. Found out after the fact I should have set the tub into wet cement to firm it up so I could keep caulk in place to seal at the surround. Thinking about drilling up thru the sub floor in several places and injecting door & window Great Seal to firm it up.
Has anyone tried this or have a different or better idea? Thanks
