I can't imagine replacing an entire tub just because of mold on some

threads.



Killing the mold with bleach shouldn't be a problem, even if some

discoloration remains.



BTW..are you sure that the tub itself is threaded? I've repaired and/

or replaced a few tubs and tub drains and I don't think I've ever seen

a tub that was threaded. Usually the fixtures are threaded and are

secured with a large nut after being inserted into a non-threaded

hole. I'm not saying threaded tubs don't exist, I'm simply saving I've

never seen one.

Now that I look closer it is a fixture thread bolted from bottom. The rubber is black (why would they use a black washer???). Looks like I got most of the Black Mold. Will give the threads another bleach application.

Thanks!
