In response to Re: 1.5" vs. 2" shower plumbing
: I am replacing a 35 year old bathtub with a 3 piece
: acrylic shower. I expect to find a 1.5' drain when
: I expose the plumbing. Besides the fact that new codes
: require 2" drains are there good reasons not hook up to the existing drain.

Reply:
All codes are 2" for shower drains, not only new codes.
The problem is that you need to reduce a drain fitting with the flow going downstream which can lead to constant clogs in the line, snaking the line properly could be a problem as well.
The reason the drain is required to be 2" is so the water being used can be carried away quickly from the shallow shower base.
Good Luck & Happy Holidays. e-plumber
