Hello,

I am remodeling an existing basement bath on a slab. I want to move the toilet about 6 ft. There is an existing 3" drain for the sink behind a wall about 1 1/4 ft from where I would like the toilet. Can I tap into that drain? Or, do I have to extend the existing toilet line?

Also,I would like to convert the bath (again, on slab) into a shower. Ideally, I would like to move the current tub drain about 1.5 ft away to center on the new shower. Any issues to think about here?

Thanks for your help.

You might consider a back outlet toilet so you could tie onto the 3'' drain in the wall, and a retrofit showerbase so you can use the same location for the drain.

If you are doing this by code the tubmost likely has a 1 1/2" drain line and showers require a 2" drain.

Please explain what you mean by. "Tappig in".
Do you mean cutting into the slab and using the existing 3" line or converting the stack to accommodate a rear flush toilet?

Ideally, you would find a shower base that would inter change directly with the indergtound already in place,(see image).
If you're interested I can link you up with this shower base.
Back to you. Tom
