In my home I had a NEO angle shower that was installed when we moved in. It leaked and had been painted white. I took it apart and cleaned it up and am getting ready to put it back together. It has no model number on it and I do remember how I took it apart but am curious as to where to caulk. I read a couple of online articles but want to do it right. They seemed to be conflicting. Some said on the inside and some said on the outside and some said on both sides. It would be nice to have a manual to look at.
