Our next project is building the bathroom walls and running the plumbing lines. We have one wet wall downstairs, with another directly above on the second floor, allowing our lines to pass through the floors as easily as possible. There will be two bathroom on the second floor with the one wall accessing both. This was a fairly trickly part of our floor plan, as we needed to make sure we would not run into a floor joist, or have drains hanging down into the living areas. We have been pleased with how quickly the walls went up, and hope to be hooked up to the septic lines and drywalling soon.
Just for fun, here are some too-good-not-to-share pics our budding photographer daughters took.
