I'm confused, I hope you can set me straight on something.
Here goes:

I'm finally pulling the trigger on renovating my bathroom.
It's just as much fun as I remember. The previous remodel
has me leery of having a contractor do the tile job, so I
went to a tile place.

The guy is telling me that they are not sheetrock installers.
Check.

But they need to put backer board around the tub area and
it needs to extend past the current tile where there is
now just painted wall, to reach a stud. Check.

This is where I don't follow and I should have gotten him
to explain.

Why can't I (or a sheetrock guy) just tape the seam where the
backer board and the sheetrock meet? Is backer board thicker
or thinner than the green board that's already up?

Thanks for any help you can give me.

Because you NEVER have an unsupported long (vertical) joint between
drywall and drywall, drywall and backer board, or backerboard and
backerboard. Any flex will damage the joint. There IS an option when a
wall is open. Add another stud at the point the 2 panels will join.
