I am finishing more of my basement and am not planning on doing the bathroom down there any time soon, but I need to do the framing all now (including the bathroom). The problem is I am unsure of what the different openings / pipes down there are for and what spacing I need to maintain around them. There is a hole in the foundation just over 3 feet away from a 4" PVC pipe coming out of the foundation. On the opposite wall there is some more PVC pipe. I have attached some pictures. From my internet research it would seem that the 4" PVC is for the toilet and the hole is a shower drain. I am primarily concerned about spacing issues. I put up 1" dow insulation on the walls in that area as I did the rest of the basement and that puts me another inch away from the walls. The 4" PVC pipe is now 16" on center away from one wall and 15" on center away from the other wall. This seems too tight for a toilet especially after the framing is in???? The hole for the shower(?) starts 38" away from the 4" pipe and starts 16" away from where the framing of that wall would come out (which would actually be more like 12 inches after the wall is there). Do you think that is properly placed?? My opinion would be just to put in a shower - not a bathtub, but to other end of the hypothetical room (where the smaller vent piping is?) is about 110" away from the wall and that seems far to me, maybe a bath would be better - I need to consider that when I decide where to put the door.
Another issue is that I am using a dricore subfloor in the rest of the basement living space and don't know if I should put it in the bathroom area. If I do, do I just mark where that hole is and I or the plumber can cut it out later? and just put it around the 4" pipe coming up? I am now really questioning putting up the blue dow insulation because of spacing issues away from the wall.
I guess I really need to decide now is -
1) whether I have to take down the dow insulation because of spacing issues
2) whether to put the dricore everywhere and put walls up over it (that is the preferred manufacturers method so if you do get water it can get to the drain - according to their website)
3) how far away from the shower drain the interior wall should be and
4) where to put the door
Can you look at the pictures and give me an idea if I'm right about what these things are and the spacing issues I'm up against? Thanks!
