An elderly rancher friend had her hired-hand install a handicapped accessible shower on a concrete floor. He did a bang up job,cutting a channel in the concrete for the waste line, setting the stall in mortar, blowing expandable insulation into every single space, and gluing every stud that surrounds it the full length of each board, including a roof deck above the shower stall. Needless to say I would destroy the shower stall by trying to remove it as it is very glued in.

Unfortunately, the hired hand used a 90 degree vent elbow under the shower drain to connect it to the waste line... at least he ran 2". It runs about 5' and connects to the main waste.

The good news is that my friend is exempt from code in this county. The bad news is that her bathroom is a toxic methane bomb from the septic.

Here's my question: I can get to the waste line directly in front of the shower stall as the floor hasn't been patched yet. While I know this isn't ideal to say the least, but could I cut the waste in front of the shower and install a trap there? What other if any options do I have?

Thank you.

There is a way, It's called a "running trap" (see image) and here's what it looks like. If you can't locate one then one can be built out of street ells,(see image) This wiil take the place of the missing "P" trap and prevent sewer gas from entering your home. Good luck and thank you for rating my answer. Tom

Thank you very much, Speedball1. I'm gluing it up as I type!

Tom's solution should work great in your case. There is no such thing as a "90 degree vent elbow " I think you are blending two terms together.

Yes, there is vent 90 Ell. It has short, sharp 90 degree turn. It is a space saver. They also make them in Street version.

A little brain gaseous emission on my part. Thanks for catching my error.
