I need to replace a worn out Badger 5. Do any of you know the difference between the Badger 5 and Badger 500? The specs look basically the same. I had my mind made up to get an ISE Evolution Spacesaver until I realized that the extra width (8" vs 6") would make it too big.

Not shore if this is the right place if not please move, thanks I'm gutting my main bath room, the only thing I'm leaving is the newer tile floor and Kohler cast iron tub. I was thinking of putting in roxal sound proofing batts all around the tub then cement board. I saw a lot of stuff on this but everybody has there own way to do it. Should I put plastic up then put in the cb, yes no and how fare up the wall? So I have to use the orange fiber glass stuff on all the joints? So I need to use come kind of printable water sealer over all the cb? What I see it seems you're building a dam pool and no water will leak out. I think that is crazy over kill but I have no idea. I want to do it right the first time and not have to worry about it again. I was going to get the delt cassidy sets for the bathroom at a plumbling supply place. No big box store!! Dose anybody know can you connect to the valve and all the faucets with say pex plumbing no sweating. I have never tried it nor have the tools for it. thanks
