Before the plumbing work started. The subfloor is still intact.
Subfloor removed to expose the drain from the old shower.
Pex tubing for baseboard heat.
New drain line extension and supply lines for the shower.
Don't fall! We had to open the floor/ceiling into the 1st floor powder room to expose the plumbing and also install ductwork for a future fan in the powder room. That's the toilet and sink. It makes for some strange noise transfer as you can now hear someone talking in the kitchen upstairs in the bedroom. It took me a few days to get used to it and not constantly look around to find "where that noise is coming from"!
