Short answer - No, Long answer - There was a sink and toilet in the shop when I bought it. The toilet outlet was in when the slab was poured. The sink drain went through the side of the steel building.
My project is building an efficiency or studio apartment with finished walls, etc. I completed the bedroom and am working on the main room and bath. The exterior wall, where the drains and water go are 2 x 6 framed walls. I am studying options on the plumbing and the shower seems to be the biggest problem.
I can try to cut the studs and run the drains inside or just exit to the outside of the building (easiest) and run the drains there. If I run the drains outside, I will probably build an enclosure to prevent freezing.
I am planning to do a drawing of the plumbing this week I hope. I already received some good advice on this site. Perhaps I can post the drawing and get additional feedback.
