I'm going plumb my basement. Can I put my bathroom anywhere? It has a drain by the furnace and there is also a plate which covers what looks to be the sewerline.
Gary gave some great advice on consulting a pro. A basment bathroom
especially with drains under the slab, is often outside the realm of a DIY project. Too many variables. You should also get yourself a book or two from the library that demonstrates this type of plumbing project. So you get a basic idea of the depth of the work involved. But the consulting pro is a definite must-see.
Plumbers often have that sixth sense on where the drain lines run underneath the slab. Imagine picking a spot at random, breaking through the floor and missing the mark, or worse yet, breaking the pipe.
You also have the option of using an ejector pump and pit or the toilets with a macerating pump. But these are best used in basements that have no underground plumbing. If the power goes out, so does the pump and the toilet and other fixtures connected to it.
Breaking the floor even if it amounts to 20 square feet of broken concrete is not an easy task, very dirty, and then all the ruble and dirt needs to be disposed of. Of course, after the rough-in is approved by the inspector, then you need to close the trench. Another mess waiting.
It's so much easier especially when building a new home, to have the drains roughed-in in the basement before the floor is poured. And a lot less expensive.
Good luck.
