I looked through the previous posts, but unfortunately nothing seemed to fit my situation.

My wife and I recently bought a house and there is "rough in" for a half bathroom in the basement. We plan on finishing the basement and the wife wants a shower in the new bathroom. I really want to avoid any concrete work to install a shower drain and I wouldn't mind raising the shower 6" if need be. The ceilings are tall (8 1/2' to the joists). Attached are pictures of the existing basement plumbing. The main drain runs parallel to the wall with the sink drain and both the toilet and sink are vented (the vent runs into the corner and up).

We would want to put the shower next to the sink (essentially on the far right of the second photo.)

Thanks for your help.

You would need to raise it more then 6" but it can be done. cut it in on the pipe to the right add in a san tee and a 2" p- trap and you are done make sure you have a 1/4" /ft. fall and you are good if you need more just ask

Given how the Water Closet is vented separately, the poster likely lives in an area where wet venting isn't allowed, which means he will need to vent the new shower as well if he wants to stay within code.

Ohio allows wet vents. (http://codes.ohio.gov/oac/4101:3-9-01) I am checking with the local plumbing inspector, but according to their website they use the Ohio Plumbing Code.

If 6" isn't enough, how much clearance are we talking about?

Curious -- Will it still be considered a legal 'wet vent' if your sanitary tee for the new shower is below the 2" wye servicing the drain pipe coming down to the right of the lavatory rough-in?

Relly there need to be a cleanout under the wye. "at the base of every stack there shall be a cleanout" but yes he could put it below the wye

I'm not trying to be obtuse here, but doesn't that pretty much fly in the face of the rationale given for why wet venting is acceptable in some instances but not acceptable in others?

Not sure what you are getting at maybe I am a little slow but if you were doing this to pass inspection you would need a cleanout at the bottom of the stack to pass
And then put the san tee on the far right pipe above the wye
For this guys particular situation if not getting inspected he could put the san tee below the wye if he can work his fittings to stay out of the cabinet..

Is that what you were trying to ask sorry if I wasn't clear on that last one
