I am currently wanting to add on to our bedroom and also add on a master bathroom where our carport is now. The only problem is that it is sitting on a concrete foundation. The current bathrooms pipes are going the opposite way of where we want the master bathroom. I have experience with remodeling and carpentry but have never delt with anything sitting on a concrete foundation. Any help would be greatly appreciated. Such as is it even worth it. And how I would tie in the sewage and lines
