I am redoing an upstairs bathroom that has galvanized steel pipes currently running to it for water supply that run straight up from the basement. I am debating between using pex or copper for the new supply lines. From what I have researched, if i use Pex, it will slap against the wall of the 1st floor since i cannot attach braces inside the finished wall without removing drywall. Is this true? Also, if i do use copper what size is recommended for a bathroom 1/2 or 3/4? and what type of braces does copper need to support it? I am planning on bracing it in the basement and at the 2nd floor where it enters.
