Toilet supply rough-in questions

Thanks in advance for any help / guidance with the following!

What is the recommended height above finished floor and offset to the left of drain center for the toilet supply rough-in?

The supply lines are Wirsbo PEX - do you recommend a brass drop ear elbow (threaded adaptor) or rigid copper rather than PEX through the wall for a more finished look?

The safest thing is to choose your toilet first! Then, you'd be assured it would fit and look good.

You can use pex and a pex compatible compression valve, but the pipe is a little floppy. Better to use a proper drop-ear el. Whether you use a soldered in copper stubout or a brass threaded nipple is up to you. The copper is probably neater, as you can get the length exactly where you want it. Note, they make pex copper stubouts that already have the 90-degree bend in them. They're designed to solder into a bracket to hold them where you want, and the end is closed so you can turn the water on without having to put a cap on it. Just cut it to length when finished when you want to install the shutoff.

A toilet supply stubout location can be affected by two factors.... 1) whether or not a skirted toilet is going to be installed, and 2) the width of the baseboard being installed (newer baseboard styles/trends are often much wider than older ones. Best to be certain before you do any rough-in work; you wouldn't want to end up with a foolish mistake once all the finishing is done.

I generally use 6" above the floor and 6 " off center of the toilet.
Again my experence is in doing lots or rental remodles.

Thanks very much for the help! We took the advice and picked a specific toilet (using Terry recommendations and reviews from this forum) to get the rough-in dimensions.

I would go six high and eight wide.
Then pretty much it works with any toilet.
I used to go six to the left, but that will hit some skirted bowls.
