A while back one of the gang was retofitting some grab bars into a tiled shower - Tommy I think. He used some sort of wall anchor instead of trying to locate studs in the walls. What was that anchor and is it code worthy? A client has called and asked for some bars to be installed in her shower and short of tearing out the tile surrounds to install blocking, I'd like to offer an alternative.
The searches I've done so far have given height requirements and minimum load capacities. And everything so far is saying to locate fasteners into studs or blocking.
