Ok, I live in Colorado and our basement floor is the "floating" concrete slab. (due to the expansive soils) My question is, while I am finishing/framing the basement and adding a bathroom around the rough-in plumbing area...How do you frame the bathroom for a bathtub? The walls are suppose to be framed via "hanging" walls (anchored to the main floor joists). But everthing I've seen or read for framing a bathroom with tub deals with the walls being directly anchored to the floor, so the tub can be connected to the wall studs directly. How do you account for the possible movement in a basement floor with the tub having to move with the floor, but the walls being anchored to the joists? Any help is greatly appreciated!! Thanks in advance! NOTE: I an a true amateur to framing and basement finishing. And I posted this in the "Framing/Subfloor" threads as well.

I'm a new homeowner. I bought my house about a year and a half ago. It's in California, and it has a crawl space beneath it. This all started when I wanted to run a wire from the outside of the house to the inside for an automatic sprinkler system. I thought I'd be able to run the wire through the crawl space vent and then drill a hole up into a wall. Well, I peaked into my crawl space for the first time. Zowie! There's debris everywhere. First of all, it's a lot more cramped down their than I had originally thought. Second, there is a lot of debris left over from previous bathroom re-models as well as fibergalss insulation all over the ground. Some of the insulation under the floor is sagging down as well. There's so much debris that it is impossible to see the other side of the house. So, I'd like to clean up the crawl space so that future plumbing repairs and modifications can more easily be made. I've also decided this job is too big for me. My question is, who would I hire? A handyman? A general contractor? An insulation specialist? I've searched the internet, but I don't see any ads listed for people who will clean your crawl space. I did see an ad for a service to clean up the crawl space and install a crawl space encapsulation system, but I don't want to go that far. I just want it cleaned up.
