Outbuilding Water Supply

I recently moved into a place with a detached garage and discovered there is a water line running to it. After consulting the previous owners, I learned that fed a sink. I'd like to add a bathroom in that building, but I don't know if the pipe is big enough to feed a toilet, sink, and shower. It's 3/4". Is that enough?

Welcome to the forums.

Most homes are connected to the city water supply with a 3/4" line.
So 3/4" between structures should be fine.

Just don't flush the toilet while taking a shower.

Thank you, that's kinda what I thought, but I didn't know where to go for such an answer. I really appreciate that!

Water supply is the easy part. What is your plan for the drain piping to connect to the sewer or septic system?

Ah, that's a good question, and I'm sure I'll come back for further insight, but for now: we have connected to the city sewer and will use the existing vent for two of the fixtures and a cheater vent for the sink!
