After reading the heck out of this thread - I am left with only a couple of questions, and many good decisions. I am in a new construction home with a poured concrete basement that has been dry thus far (will wait out the spring before I begin). I am attracted to the steel framing for its ease and lower cost. I have learned that I should use a basement treated wood stud at the bottom track so I have something to nail the baseboards into. I am intimidated by drywalling, and like the look of panelling - so I am willing to pay the higher price (15 vs. 6 bucks) for the panelling (I figure I need only about 40 sheets - so the difference is only a few hundred bucks - hopefully I'll save that in the steel purchase) Problem #1- can I even use panelling with steel framing?? With wood - I can buy panel colored nails which won't be visible. I don't plan on painting the panelling - so will the screws required for the steel framing look terrible on the panelling? Problem #2 - insulation - how do I attach insulation to the steel frame? The flanges normally get stapled to the wood studs...but here I'm out of luck. Do I just tape and let the screws do the job when I put up the walls???

No question here, but I wanted to share some info with the readers. I got enought information from the posts to tackle removing a cast iron tub by breaking it with a sledge hammer. With 8 pound hammer, it took about 45 minutes, including hauling the pieces out. Break it into as small of pieces as needed to remove. It wasn't as hard to do as expected and much easier than tearing out a wall. I have a couple of pictures of the task if anyone wants to see them.
