In response to Re: Drain size
: Hi,
: I am remodeling my master bathroom. I want to install a shower where the tub once was, and tub where the shower once was. The existing drain for the old tub was 1 1/2", but the code for shower is 2". My plumbing inspector said he would let me use the 1 1/2" for the shower. My question is whether or not the 1 1/2" will be adequate for the shower. I would appreciate your thoughts. Thanks.

It's hard to believe that a plumbing inspector would allow that.
It probably would work but it will be prone to clogging at the point in which the drain line reduces in size. The reason the drain for a shower is 2" is so the water can be carried away quickly from the shallow shower base.
Good Luck. e-plumber
