With a bathtub on a slab, is the trap typically left exposed or concreted over?

I've already installed the (glued) trap, but I'm not sure whether I should box it in and leave it unconcreted, or go ahead and concrete over it, leaving just the stub-out. The tub will be in a platform, so there's no issue with the current install. I'm just thinking about access for future service.

I'd leave access to the trap and trap arm (or a certain amount of it anyway) so that in the FUTURE if you ever want to trade that tub out for something different and it has different dimensions you might be less screwed.

Leaving access to plumbing is never a bad idea.

"Access in the future" for what? If it is done correctly in the beginning, there is no need for access EVER.

I'd leave access to the trap and trap arm (or a certain amount of it anyway) so that in the FUTURE if you ever want to trade that tub out for something different and it has different dimensions you might be less screwed.

Everything's tight and solid, but the trap is half in the footing, so a future change/move would be a HUGE PITA if it's all concreted in. Guess I'll be considerate to any future plumber and box it :)

trap

You DO NOT have to pour it solid with concrete. Sand fill with a concrete topping is the normal way to do it. And you may be the first person ever to worry about how a plumber would do something in the future and make it easier for him.

In the state of Florida code requires you to cement it over.
