There are 4 separate bathrooms in this building. One in the one-story building, two stacked on one another in the two-story building, and a private single occupancy on the second floor.
1st Floor Bathroom
One of the biggest challenges was modeling the connections between the toilets, but once I was able to figure out T connections, it worked well. Stacking the two bathrooms also made the process more efficient and saved material because I used the same vertical pipes. Additionally I wasn't able to connect to the sanitary pipes initially because the angles were too tight, but one I lowered the pipe I was able to connect.
