Hi,
Watching new house going up, they install tub and drywall goes on(the
green water resistant one)

The green drywall was a mistake they came up with after mud-bed tile
jobs became too expensive during the building boom of the 1950s and 60s.
(Or they didn't have enough skilled tile-setters to do them.) It is no
longer considered good practice, since it is only water resistant, not
water proof. Grout always leaks, eventually, as does the water seal
where faucet handle penetrates the wall. Most regulars on this group can
describe all the mushy green drywall they have ripped from tub
enclosures over the years. Use cement backer board on the walls around
the tub, and use the green drywall (or better yet, the yellow non-paper
stuff), in the rest of the bathroom where it only gets damp, not wet.

Yep, and it's only done, today, as a low-end corner-cutting measure. Any
DIYer doing it is simply nuts.

And yes, tub goes in first, against the bare studs. Use this
once-in-a-lifetime opportunity to insulate around and under the tub,
especially if it butts up to an outside wall. Guys seldom take baths, so
we usually don't care, but SWMBO will appreciate the bath water staying
warmer longer.

Quiets the tub, too. Cheap enough.
