Here's a page that documents the concrete and granite work in the foundation
of the bathroom.
This is what I spent the early days doing. Lots of
time breaking concrete, running pipes, mixing concrete, etc...
An air-chisel makes pretty quick work of the 4"
concrete slab where the bathroom plumbing runs. Concrete is
relatively soft - unlike the granite bolder that I found in the hole where
the pump basin was supposed to go.
This is the bathroom floor before there was a
bathroom. Since the house drain is much higher than floor level, we
needed a pump basin (upper left in picture) built into the floor with all
drains leading to it. Each drain also has a vent pipe that goes
through the walls and tie into the house venting system through the roof.

Five minutes of chiseling with the air hammer and not even a
chip! Luckily, an SDS rotary hammer with a carbide tip 12" bit
only took 5 minutes to make a complete hole through the bolder.
Seven holes later, and using drift punches as wedges, the rock was two
rocks, and I could clear the way for the plastic basin and sink it into
concrete. Somehow that eighty pound rock doesn't look too deep in
there unless you compare it to the shovel that's next to it in the hole.

Because of the Buoyancy of the plastic basin and the high
groundwater, I had to brace it down against the ceiling while the concrete
sets.
Here's the finished basin - set in concrete and separated
from the rest of the bathroom by this wall.
