Plumbing!

Here is the upstairs bathroom which was Thurston's room.  We'll call it the second bathroom for now.  Anyway, where the ladder is standing is where the toilet will be set, as you can see on the below photo, the white round cover is the flange.
 

Below is the vent pipe for the toilet.

Below is the first upstairs bath, formerly the wood room. We have Jake getting ready to drill for the toilet flange.

 

And here it the venting, right to left, for the shower, toilet, and sink.

In the kitchen, a bit of demo for the drains coming from the first upstairs bathroom.  

Here Jake is setting the drain for the shower/tub in the second upstairs bathroom and to the right is for the sink and toilet drain.  
Things are coming together!
