Hello,
I am installing a full bath (w/shower stall) in my unfinished basement. I need to run supply lines for the toilet, shower, and sink from the laundry room which is adjacent. The current lines are C-pvc. I guess my question is:
1) What is the best way to run the lines? And what size should lines be?
2) Also, is it a problem to run all three fixtures from just two lines into the bathroom?

Sorry for the lack of correct terminology, I hope I have conveyed my question meaningfully.
Thanks in advance.

1) What is the best way to run the lines? And what size should lines be?

Some areas, such as mine allow you to service three fixtures off a 1/2" branch and some codes hold you down to two. Check with your building department.

2) Also, is it a problem to run all three fixtures from just two lines into the bathroom?

By my code no! However if you were held down to two fixtures off a 1/2" branch you would have to bring the cold water in with 3/4" and branch off with a 3/4 X 1/2 X 1/2" tee to pick up the other two fixtures. Again, check the local codes. Good luck, Tom

Thanks a lot Tom!

Also, does it matter which line I tap into? (i.e. washer, main line, or other existing lines routing to other areas of the house)

No, just as long as it's 3/4" main. Good luck, Tom
