Went today to install some grab bars for a lady whose husband is coming home from rehab after breaking a hip. She wanted to install a grab bar by the commode and 1 in the shower. Shower, no problem found the studs, pretty straight forward. By the commode, different story, it is a cement block wall that separates the 2 condos. So now all you have is 1/2" drywall and a 1x furring strip then the block wall. This gives you 1 1/4" of useless space as the drywall or the 1x have no holding power how would you mount this bar? Oh and the man is 6'2" over 200# not a little guy.

Some folks use the Tapcon screws but they are a little pricey. I have drilled a hole the same size as the screw threads in the wood and on into the concrete wall. Take a #12 electric solid wire strand, leave the insulation on the wire, insert the wire in the hole then screw the bar to the wall. You can not pull it off the wall.

Can you find the furring strips? If so then your stuck with using 3" long Tap Cons.

I thought of that Jim but was a little leery of the Tapcons because they are so brittle. Remember this is a big man.

Good news/bad news-----open up the drywall----add solid blocking---replace the drywall---then use Tapcons or that copper wire (I like that idea) and repaint the bathroom.

This is a life threatening failure if your work fails because the grab is installed over a void----these aren't decorative do dads---a fragile big guy will be relying on them to hold his weight---

More work,yes---so charge for it----

ok add solid backing still has to be 1x stock and the Tapcon have to be the smallest ones to fit in the holes in the bar.

Perhaps.... Custom grab bars, w/ a 4" diam fixing plate with 4 holes for TapCons and tapped for small machine screws; as mentioned, this is serious. Make wooden discs that cover the fixing plates of the grab bars, secured (eventually) to the fixing plate. Cut the sheetrock. Insert the grab bar flush to the concrete. TapCon the H out of them. Install wooden discs, screwing them to the fixing plates. Plug the holes in the sheet rock. Yes, very expensive; so is falling, esp for YOU.

The fact that tap cons are so brittle and the heads snap off so easy is not a problem.

They have some new heavy duty anchors for TV mounts that can hold 200lb tv's. Maybe you can double that up instead of the tap-cons.

Just a thought.

That method Jim mentioned is safe---drill pilot holes through the board and brick---add an anchor (the copper wire) and send those long coarse screws into it---You will have a good strong and safe grab bar---

I installed nearly 200 grab bars in the last two or three months---You will be quite safe in my opinion.
