I need to run supply lines for a bar sink, toilet, bath sink all sharing the same wall (3 colds, 2 hots). Should the two horizontal supply lines I bring over off the main 3/4 inch lines be 1/2 inch or 3/4.

Thanks,
Larry

You're fine Larry,

Code calls for a 1/2" branch off a 3/4" main with no more then 3 fixtures being serviced by a 1/2" branch. Your set up conforms to code.

Thanks for the quick repsonse
