I've also posted this in the bath forum. We're remodeling our master bath and I'm looking to put polished nickel grab bars in our shower. Is there anyone who has used them and can give me some feedback as to how they hold up? I'm thinking of getting the Columnar that have a 1 1/4" diameter. Also, if anyone has retrofitted one of these to use as a vertical slide bar for their handheld shower, I'd be interested to hear about your experience as well. I'm considering using the Jaclo adjustable sliding shower mount with the Ginger grab bar. The mounts work with 1 1/4" diameter bars. We're looking to install Hansgrohe polished nickel shower heads and trim. Their PN is different from the Ginger and Jaclo it seems, but they don't make grab bars, so I don't see a way around mixing the polished nickel finishes. Hopefully it won't be too noticeable. Do you think a regular Hansgrohe slider would be sturdy enough to use as a grab bar when getting in and out of the shower? TIA

You are not going to really be able to get into the studs as is required. Never trust anything mounted into fiberglass. That’s an injury waiting to happen. You should be planning on redoing that thing entirely. False. Moen, for one, has a system for securing its grab bars when there’s no blocking available. Moen Home Care Securemount anchors

Maybe I'll get something like this, that has function other than the grab feature. https://www.homedepot.com/p/MOEN-Home-Care-16-in-x-1-in-Concealed-Screw-Grab-Bar-with-Shelf-in-Chrome-LR2356DCH/203623698 I plan to do kind of a focal panel on the wall that will need the grab bar--maybe I can have the bar just under the panel so it looks more like a design/functional element.

We didn't add any yet to the house we built, but we had blocking added to all the shower walls, placed approximately 36" from the floor. I should probably add some grab bars soon to the guest shower my parents use when visiting.
