Out to pasture
You could see if wrapping the frozen bottles in a pillow case will help. Just realize that the rabbits will probably chew on the fabric though.
Our rabbbit is outside in an open pen with a concrete floor. It is shaded with a tarp. It stays nice and cool on all but the hottest days (over 100). He doesn't even sit next to the frozen water most days.
You could also try freezing some sort of stone. I have used chilled terrazzo tiles to help cool the rabbit. I was out of frozen water and looked for something else. I had them in a cool area of the patio and used them.
