Bath rough in distance
What is the standard rough in distance for a bath tub drain from the wall? This will be in a basement floor, so I would like to get it right beings it will be in concrete.

Your best to get the rough in from the tub or shower you plan on using. Standards are at times deceiving.

tub distance
Thanks for the info. Is it ok to leave a 16"x16" blockout in the concrete there to allow for the drain to be moved to the exact location when I do get the tub? Of course I will have the 2" drain line under the concrete, but then the trap can be rotated to fit the tub drain.

I would recommend a 3" drain for the shower. You are running a 3" for the toilet anyways right? As for leaving the 16" x 16" block out that should be fine. Depending on your inspector. When you run all this plumbing under you should also add a back flow valve to the system. It is code in some places and just good practice anyway. It will stop backups that start outside, from ruining your work.
