He makes me tired just looking at it...


It's easier when using many small pieces as it appears he was doing. The
downside it more drywall compound and sanding.
The smaller sheets were used under plaster - no taping or mudding
of the seams. ... perhaps under bathroom tile in this case ?

That looks like what's on the oldest walls in my 1947 house. It's rock-hard
and weighs a ton; I can see why they didn't use 4x8 sheets. Every
one of those walls is skim-coated with plaster. Our bathroom was
different: metal lath nailed to the studs and covered with a buttload
of plaster underneath the tiles.

We called the smaller sheet-rock panels "lath" -
but "plaster & lath" usually refers to the older type of lath -
with the thin wood slats .. might be a regional terminology ?
The lath panels of the early 1960's often contain asbestos -
as could the plaster.
