If you have the shower kit with the age-in-place backers or have installed supports behind that kit, then I would guess that the answer would be Yes. I assume that most grab bars would work with that shower kit since it is supposed to allow for grab bar installation.
No, the bar is connected to the sides.
I believe it is 250 Lbs, but since it was able to be installed into 2 studs (one at either end of the bar), I think it probably could handle more than that.
It comes with wood screws to attach to studs only. The brackets have flexible spacing and we were able to get at least 2 screws into studs. Moen's anchors would need to be purchased separately.
I have two of these and have used them in my shower for two weeks. They appear to be waterproof.
