Hi there I can see there have been discussions about this before, but I'm not clear whether a grab rail can be installed directly into plaster board. The grab rail we're wanting to install is intended to help lift a heavy person up and out of a deep, soaker bath. It's a new bathroom and a false wall has been installed and tiles are now applied. Assuming we could confidently find the studs, they may not be in the right place in terms of height forr the person reaching up, so as to help lift themselves out of the bath. Therefore, do you think we could install a grab rail directly into plasterboard (not cement/hardi-backer board)? The tiles which have been installed onto the drywall are natural stone and are large at about 1.5 feet by 1.25 feet. I wondered whether this fact would help, given the surface coverage of these tiles. If you don't think the above would work, can you recommend some retro-fix solutions that would work without having to wreck the existing wall, please?
