The unfinished portion of the basement is going to be a new downstairs bathroom.

First, we cut a hole in the slab floor for a pump to get the gray and black water up to the septic and drain field. That's the hole in the corner - covered temperarily for my safety.

We then put in the main plumbing wall - an interior wall from which to hang the plumbing fixtures. You can see the stubs for the two sinks.

Into the plumbing wall, we add all the pipe, the electrical wiring and a short knee wall. The blue boxes are the electrical switch and termination boxes for the light fixture.

We also got the pump installed into its hole and connected to the main plumbing line.

Now its polish the surfaces - paint the walls, marble the floors, get the countertop installed, and add the end cabinet and lighting.
