Yep, that's the only option I had short of putting in a septic for that one bathroom.
Got the concrete in today.....not as bad a job as I thought it would be. It took 20 60lbs bags of concrete. Tomorrow I'm off to purchase the shower stall and the shower valve. Then I'll frame in the closet where the sewage pump goes, plumb the supply lines with pex, insulate then drywall.........it just never seems to end!!!!
The ceiling tiles in the pictures are not done because the nimrod that estimated how many tiles to order (which would be me) didn't get enough and it takes Amrstrong over a month for special orders.
