Author Standard location for bathtub drain?

I am in the process of roughing-in the plumbing for my new house. I
plan on using a run-of-the-mill 32" bathtub (whatever's on sale) in the
least used bathroom. For toilets and sinks, there are well defined
standards for drain location (e.g., toilet drains 12" from finished
wall). However, I have been unable to find any standard for 32" tubs.
Is there a standard? Or do I need to go and buy the darn thing and
measure it? ........thanks for the comments....rwm

It is roughly 12" from the wall. I think the normal floor cutout is 4x16"
from the framed wall.

Some of the newer acrylic tubs actually manage to keep the drain line above
the joist level because so many homes are now on slabs. You would not need
to buy it just go to the store and measure it.

Or just measure the one in the home you are in and allow for the drywall.
The distance from the wall has been the same for at least 30 years.

Well, that's not true on the tub I am using for the master bath. In
this tub, the plumbing from the bath's main drain branches horizontally
over to the pipe that drops vertically from the overflow drain. They
are joined at a sanitary tee. Then, the exit of the sanitary tee is
connected to the bath p-trap. For this tub, the p-trap should be
positioned about 4-5 inches from the wall. Sounds like there is no
standard.

There are plumbing codes to consider. This question is probably better
handles at alt.home.repair

I would consider spending a little extra for a nice looking tub. Tubs
are a pain to change out after the bath is finished.
