Since I finished everything above the floor for our addition, except the insulation and drywall which will be contracted out, I spent a lot of time in our crawl space (both under the existing structure and addition) doing the under-floor drain piping. Unfortunately the master bedroom bath of our addition has the lowest crawl space to work with. I think I become at least half mole or it reminds me the basic military training that I went through – doing military low crawl. I guess there are a lot reasons that this time it is worse than that – for example, the uneven concrete, bricks, used wood, sharp objects, junk, etc. Air is bad too.
Hopefully, I should finish the piping & drain work soon and wait for the city inspector 🙂
