Kate and Beth's treatment rooms or Kate's and Beth's treatment rooms

[ColgateSmile]

Hi

I am writing the location of a fire door between Kate and Beth's treatment rooms - two separate rooms each belonging to Kate and Beth.

Which is correct:
...Kate's and Beth's treatment rooms
....Kate and Beth's treatment rooms

Many thanks

If you say "Kate and Beth's treatment rooms", it means that there is more than one treatment room and they both/all belong to both Kate and Beth.
