Bathtub drain - subgrade
So I'm wondering if I've got myself into a pickle... We're finishing off our basement and decided to add a full bath. Apparently not thinking (:furious:) I believe I might have ran the bathtub drain line in a not so ideal direction. The picture below shows that drain line below grade as the green box. I'm curious if I'm going to be able to get the drain/overflow/trap plumbed in that area? Looking at our drain upstairs, the drain line runs from the drain end of the tub towards the other end of the tub, completely opposite than what I did in our basement.

Anyone have any experience plumbing a bath that looks like this? Thanks!

Upstairs drain (for reference).

Is your drain on the opposite side of the pic of the bath? and is the drain line in the dirt the line you want to tie into?

Where's your overflow pipe for the tub? Isn't there usually a vertical pipe going up to the overflow (and sometimes a cleanout cap above that)?
The way you have it now, it may be very difficult to get a snake into the pipe when it gets clogged, since you will have to go in through the drain. I would put in an overflow, and extend the pipe higher than the overflow (so it's at least a foot higher than the tub itself, not sure what the code is on this though), then cap it with a screw-on cap. You will also need to provide access to that pipe from the wall somewhere.
A closet on the other side of the wall would do nicely.
