Hi thegardner I don't see why this could not work in your shower, and look gorgeous too. But to make sure, i would contact the MFG just to be on the safe side, but i bet you can.
Hi john The closet thing to a brushed finish, would be the stainless and they also have chrome. Other finishes also, but the closet would probably be the stainless finish.
I don’t remember what the exact weight it says it’ll support, it just depends if it’s installed in a stud or not. But I’m about 180lbs and had no problem with it. Of course do t yank on it or jerk yourself up and I’d say if you 200 lbs or less you should be fine. If needed for a person that is more than 200lbs, make sure to install in stud. Reinforce with more 2x4 studs inside wall.
