With the old bathroom mostly gone it was time to start the new one. We are using metal stud framing for the walls, it’s lightweight and very easy to install.
But then we hit the first problem: the floor drain would not work properly with the planned new shower base! A properly built shower base contains a PVC liner that seals the shower area and directs water to the drain. There was no way to secure the liner to the older floor drain. A new drain was needed, which meant digging into the concrete. Scary!
To fix the drain we got the assistance of a professional plumber. Since he was already there we had him also dig up the toilet drain and move it further away from the wall. This lets us do a nice finished back wall, previously the toilet was right up against the concrete brick wall.
