Thanks for the replies. Ken - I don't know where you live but here in
San Francisco there's no way you'd find someone to do a proper tile job
for $400. 3 day job? That's $16/hour... no way.

But right now the green board is around the tub going up to the 10'
ceiling. Again, the contractor's plan is to install wonderboard on top
of the green board 6 feet above the tub and put tile on top that. It
sounds like that it would be better to have just the wonderboard
against the studs but is there anything *bad* about this install
method. The green board is already installed - should I rip it out? Ken
your remark about the flange is not a big deal. The wonderboard will
come over the flange and just grout/sealant/whatever at that join.

And yes I understand that mortar is the best way to do the job but I'm
not considering that here.

One thing I like about this plan is that the tile part will be 3/4"
from the wall giving a thicker look to the tile which I like better
than just a "surface mount" tile job.

Thanks.

You ought to at least consider a waterproof membrane between
the cement board and the green board. We just had a tile
job done and the order was (starting from the outside):

tile - thinset - mortar - aquabar - greenboard - stud

(Aquabar is a tar paper like material) The greenboard was
simply used as a spacer to aid in getting the right plane
for the wall.
