TedL, the first time I checked for studs I did not find any. I'm gonna check again with the electronic studfinder.
It gets weirder, I said before that there are 2 sheets of OSB, but i found out there is only twos sheets at the top half. I accidentally made a hole in the bottom half and found that it is a single layer of OSB, then a vapor barrier and pink insulation. I can stick a screwdriver in the hole several inches. A friend speculated that someone added a sheet of OSB as a spacer for a narrower tub. In any event I will investigate further.
Thanks.
