best size p trap?

| I'm installing a new tub. The tub has 1-1/2" drain connecting to a 2" line. It's a little less than 3' to the 3" stack, no revent. Would it be best to increase to a 2" p trap or use an 1-1/2 trap and then increase to 2" |

| code standard for a tub drain is 1-1/2". Code permits increasing the size of a trap or drain line by one nominal trade size therefore either one would be acceptable. |

Thanks Lazypup, for the info. but I'm still wondering if one way would be better than the other? Would a 2" line following a 1.5" trap, vent better? would a 2" trap preform better? Or am I just way over thinking this.
Thanks again. |

| Actually a 2" line would reduce the velocity of flow and could result in clogging more frequently. |
