Yes it is correct

Awesome. Thanks again. I'll probably be ordering the supplies soon. Hopefully that ends it for the questions!

I guess I'm not done with questions:

Thanks eplumber for your help across several threads. I just want to confirm a couple more things:

So the tee that ties the urinal into the 1" PEX supply could be reduced to 3/4" PEX to service the toilet and the sink, correct?

And I think this was answered, but to be clear: it doesn't matter where I tie into the main line? Or does it? (Would I be any better off tying into my main just after the meter, and before any other fixtures are fed? Or would it not matter how many other fixtures are fed off the main line before I add my 1" PEX?)

Finally: how devastating would it be to add a second 3/4 tee before the urinal to supply a bar sink and dishwasher?

Yes, I would run 1" to the urinal, then reduce to serve the other fixtures.

The tie in location doesn't seem to be critical based on my knowledge of your layout. If convenient, I'd place it before other fixtures though.

You can add the sink tee- shouldn't affect anything. It could be a 1/2" branch for the sink and DW- the faucet has a flow restricter to limit water usage well within 1/2"

When running pipe to the urinal, use copper to stub out the wall- most urinals come with a "sweat/solder" adapter to convert to the flush valve assembly. This makes for an easy connection to get the stub out length correct. It's explained in more detail in the instructions. You can probably google for a PDF file.
Anchor the stub out well to eliminate movement

Alright; ordering the supplies today: I have 1" PEX going to a 1",3/4",1" tee.

I figured the 3/4 would run to the sink/toilet wall, then use a 3/4 to 1/2",1/2" tee to serve the toilet and sink.

The 1" portion of the main tee I wanted to run to the urinal: but I can't seem to find a 1" PEX to 3/4" copper reduction coupler for uponon.

The way I see it is I can use a 1" to 3/4,3/4" tee in the main branch, or make a custom stub out using 1"PEX to a 1" copper pipe, reduced down to 3/4" copper?

Or am I over engineering here? I just figured dropping down to 3/4" PEX at the urinal may restrict water too much...
