I'm looking for a cover for my hose bib shutoff valve access hole in the ceiling of my basement that I'm finishing. I know I could just use a return grille, but I was wondering if anyone makes a more elegant solution.
I was thinking a 12x12" plastic panel with a snap on/off flush cover. In a pinch I was thinking I could use a two or three gang multimedia outlet box and then the faceplate would be the cover. Does the IRC or applicable plumbing code specify a size requirement for such access panels?
