45 or 90 before P Trap

[CtZ88]

Hello all. I had my plumbing completely replaced by a pro. However, one of the showers wasn’t ready (drain placement was undecided still) so he roughed in everything except for the p trap and arm. I plan on finishing that off myself and it will be a linear drain against an exterior wall. So the drain is right above a foundation wall. With that being said, is it better to do 2 45s into the trap or 2 90s? See attached image.

All things being equal, 45s are generally better. Will this trap remain accessible, or will it be covered up by a drywall ceiling?

Thanks. It will be accessible.

That accessibility brings up the possibility of using a slip joint trap. And that also brings up the possibility of using a "double offset".

Often it is good to get a double offset, and cut it to give you a pair of slip-joint "street" 45s, and that could be potentially useful to you.
