Bathtub P trap and vent

[Camodeer1986]

Hello. I live way out in the middle of nowhere. I am installing a freestanding bathtub and was wanting to make it to where my bathtub would drain towards my garden. Do I need a p trap or vent if installed for this?
Thanks!

I concur with TWX, and don't forget to vent that sucker.
