My understanding is that almost all the studios on the FIRST floor of CCV are ones with tubs. See this post:

The first post of this thread (
https://www.disboards.com/threads/vwl-groupies-lovers-thread-special-collectors-edition-updated-16-aug-18.3242976/ ) has a floor plan of the CCV villas. You can see that other than the first floor, the studios are pretty spread out on each floor, but yet still clumped in a distinct pattern from floor to floor [pretty much same place on each floor].
There is a discussion in the CCV thread (
https://www.disboards.com/threads/•the-official-copper-creek-villas-cabins-owners-lovers-group•.3631019/ ) specifically about where the studios are and what type of shower vs tub they each have, with people noting room numbers and what that room had [see start of it here (
https://www.disboards.com/threads/•the-official-copper-creek-villas-cabins-owners-lovers-group•.3631019/page-58#post-59014897 ). Not sure how many are "unknown" at this point, but I think most of them have been figured out.
FYI, according to information in the "Disney Vacation Club Information" forums, there are "78 studios" of which "41 have walk-in showers and 37 have tub showers." There are 42 dedicated studios and 36 studios that are part of a 2 bedroom lockoff. 30 dedicated studios are on the first floor, plus ? 1 ? lockoff. Note the lockoff and 1 dedicated both include the alternate studio configuration.
4115 is an alternate lockoff with walk in shower.
