Hi All -
I'm updating a shower from 1970 and replacing the old concrete shower base with a Kohler acrylic base. I knew I might have to reposition the drain but was ok with it because the shower will be a bit bigger. The base I bought is nearly perfect but the drain has to move 1.25 inches in one direction. Would you recommend using an offset drain? Oatey 103 series looks like it would do the trick. [www.oatey.com]
Should I use ABS or PVC?
WHat's the best way to connect? I've read a lot about Fernco couplings?
you can see an image here. looking to move it to the right. [postimg.org]
Thanks!!!!!!!!!

I would move the drain line to accommodate the new location. It looks like there is access to the line and it would be simple to move, then repair where someone has chopped away the floor joists.

it may seem like more work but what my friend from MO is actually less work. i don't believe you have enough vertical distance to just change the trap riser.

OK thanks - i was recently told to replace the galvanized piping which connects to a copper drain line - so does it make sense to cut the copper line and connect a new pvc pipe to the copper? if so i can just measure for the new base and not worry about the offset drain.

I would remove as much of the copper drain as possible and put back pvc. Copper drains connected to the sewer system (as opposed to indirect drains) are constantly exposed to moist air and tend to corrode badly on top. If the drain clogs at some point, an auger will make pinholes everywhere down the pipe. This only seems to happen to horizontal runs and the heavier walled 3" and vertical copper aren't as prone to the corrosion problem. Cut out the drain, set your base, then rerun the drain in pvc.
