OK. Here's what I got. A 5'x10' corner basement bath, the floor was about 6" higher than the slab in the rest of the basement. They had built it up but in doing so had simply laid 2x's on edge in the dirt, needless to say because of leaks and being in the dirt, they rotted, so we ripped it all out, and are now planning on pouring a slab in there .

So heres a pic of the cast plumbing laying in the dirt. What you're looking at is an app 2'x2' slab poured on top of the cast piping, it looks like they had cut a hole in the floor, used some vinyl flooring for a form and poured it. You can make out the vinyl flooring the little black diamonds along the top edge of the slab. If you look closely you see the 6" cast pipe coming under it from the right and going out to the left. The only thing I can think is they drilled into the cast for those two drains you see in that slab. The white pvc you see is from the first floor, the black ABS piece you see sticking up is the drain for the tub. You can also see the toilet flange in there jutting out from the lower right it has a rag sitting in it.



So I'm wondering the best way to proceed. Should I try and pour a slab around all that crap and will it adhere to that existing little slab enough to install a ceramic tile floor..
Or should I rip it all out and install new.

And how much do I need to cover the cast with concrete, because the 3/4" subfloor that was on there sat right on top of the cast, and the ceiling height was already critically low when standing in the tub.

Any ideas fellas???

Wow thats a mess. The CI will hold up no problem with just a inch of concrete above but the issue you have there is the way they have pipped into that CI soil pipe. I wouldnt build a new batroom over the top of that mess unless it was all taken up and repaired. Maybe take that concrete up and see how they have piped into the CI soil and see if they used some kind of boss or saddle adaptor. You have to be carefull as you have a couple of branches that could be a pig to replace if you damage the CI pipe or fittings. If ya gonna do it make sure ya do it right and take that mess out.
