Hey folks,

There's a small shower in my laundry room, and I'm planning to replace this
with a laundry sink. As I usually do, I tore into the destruction phase
before planning out the rest of the job. :-) I've got the shower surround
ready to come out, and I'm working on detaching the drain from the shower
pan.

The water lines should be relatively simple to connect: there are tees on
the hot and cold pipes for the washer that currently feed this shower. The
question is, how can I convert the shower's floor drain to a suitable drain
for the laundry sink?

Thanks,
Peter

The shower drain should be 2". You'll have to discover what material
the pipe is.

If there is ~1" of pipe sticking above floor, use a Fernco rubber
coupling to reduce to 1 1/2" *tubular* size (that's what the sink
drain will be).
If the pipe winds up being flush, chip out enough floor to get a
coupling on.
The shower should have a trap under floor, so none is required
on the sink.
