Hi,
Joist is typically 16" OC. If the house is built properly, it'll support
the tub without any trouble. My house has a Jaccuzi tub in our master
bathroom upstairs. No issues at all.


Don't count on that. Find out for sure what the spacing is. There are
quite
a few products out there now that only require floor joist to be 24"
o.c.. Look
in your basement/crawlspace if you have one.

Hmmm,
I know every thing about this house of mine built in '94. Wife designed
it with a help from an architect, hired a contractor with excellent
reputation(he built our last house). I still have a set of blue prints.
Framing, wiring, plumbing, hvac duct runs all can be checked and traced.
