Ok. I am back again.
I am adding a bathroom off of a gameroom upstairs. The bathroom will be built in existing attic space. I have water, hot and cold, but no 3" sewer line. I have three full baths downstairs on slab on grade. Two of them I could drop the 3" line down their interior walls. One is at the very back of the house. Here, plumbing should be closer to the slab correct? The other in the middle of the house. Plumbing here is a little deeper and may be harder to get to. Either will work. The question now is do I bust up the concrete slab with a large hole and tie in from above the slab. I could do this in either bathroom. Or do I get someone to dig a hole and approx 6 foot tunnel under my house and punch a 4 inch hole thru slab and tie in pipes from underneath. This would be done to the bathroom in the back of the house. Closer to exterior walls. Anyone have experience with this?
Had a professional plumber take a look at my job. $1,600 just to run a 3" line down a wall and tie into main drain under slab. Yikes. Thats why I am back to doing this myself.
You guys have been great with all the info and I appreciate it.
