Hi all,

I'm about to run the PEX for my bathroom. I'm adapting from 1/2" copper main to a 3/4" PEX line.

Will it make any difference if I run a branch off the main for my bathroom versus individual line off the main for each fixture?

If I run a branch, I can get away with one set of shut-off valves for the whole bathroom (shower, tub, toilet, sink).

I've added a pic to show what I mean.

Thanks in advance.

Individual uses more length pipe and may be more work. Many run a "manifold" with many outputs, and many of those manifolds have individual shut-off valves for each tap.

Individual will get hot water to come out of the shower sooner because the line has less cooled water to displace.

For shutoffs, you want a shutoff right at the toilet and normally for the lavatory faucets, even if you have individual shutoffs

Hey, wait a minute.

This is awkward, but...
