I'm getting ready to install plumbing for the shower in the basement. Two probably stupid questions.

1) do I need a trap?
2) how far up should the top of the pipe be that comes out of the floor? Should this pipe be level with the top of the concrete? The drain for the shower would then attach to this pipe.

Are there any tricks for doing this correctly?

Thanks.

1 Yes - you should have a trap.
2 Leave the pipe long and cap it. Once you get the shower pan you'll know what the length needs to be.. would hate to go flush and then have to chip more concrete to extend it.

When I installed the plumbing for my basement shower, I had the luxury of doing it before there was concrete in place. I ran the pipe high, and wrapped it with foam so there would be a void about 6" in diameter. When I installed the shower, I had to cut the pipe off right at the plane of the concrete, and rip the foam out of the slab. When I did that, I had enough room for the drain.

The true answer will depend upon your shower and drain.

BTW, wasn't sure if you were aware, but most areas require 2" for a shower only (whereas 1 1/2 for tub/shower, strange isn't it?).

Hmmm, - - tryin' to figure out the logic to that one.

Thanks for the input. I have 2" pipe in the rough in already, so I'm ok from that perspective.

I think the 2" pipe for a shower gives you a better chance of the drain not clogging(man that sounds stupid---duhh). With a bathtub, if you have a clog or a slow drain the excess water has a place to sit. With a shower only, you have overflow that much quicker.

Yeah, I guess I never thought about that. Good call.

Makes sense, Valent, - - that must be it.
