I'm redoing a second floor bath. Replacing tub area tile and tub. There is NO access door to the suppy lines and drain (other side is a bedroom).
Can I install a new tub drain and overflow drain and connect securely without opening the bedroom wall ( or worse the celling below)?
Also because of the weight, what is the incremental difficulty of making the connections if I choose a cast iron vs. a steel tub?
Not starting the demolition until I know how BIG to make the dumpster!
