Closet auger:

is far too large to go into a tub drain, it's
designed for toilets.

That is why I said you go down the overflow.

And, as you pointed out, some bathtub drain lines are configured in
a way where that will work and some are not.

I'd be curious if a closet auger will fit
into a drain over flow for a tub. I rather
doubt it. I await a field tester to report
here.

I understand your point, and a closet auger does seem like it would tend to
be ratherr large for this type of drain line. But, I have designed and run
new bathtub drain lines for a new tub from underneath, and when I can, I
design them so that a snake placed down through the overflow would go
straight down into a trap and then back up and then continue on inside the
horizontal drain line. I like to do it that way when I can to allow for
easy snaking out of the tub drain line. I haven't tried it, but I think
that the ones that I have designed and installed would accept a closet
auger.
