Installing a Grab Bar
Not a green building question, but I like the experts here. I need to install a toilet grab bar in our guest bathroom for a regular guest. Sounds like a simple project, but . . . . In pics, you can see the grab bar, one of the few with mounting points 16″ apart.
Pics also show the wall in the bath with the two studs marked by blue tape and you may be able to see the drilled hole between tape points on left. Last pic shows the wall, pre-insulation from the outside of the wall in the garage, so pictured studs are reversed from finished photo inside bath.
For sure, the junction box for fan on inside bath is 43″ off floor as marked in black. The lower mount, below the garage outlet, marked in red, is 32″ off bath floor but only estimated location in picture. Green is the planned grab bar location.
Because mount covers are already attached to bar, it’s a bit difficult to drill perpendicular to the wall. I utilized a 3/32″ x 12″ long bit to help with that. The included screws are 2-1/2″ long, plus 1/2″ drywall, I marked the drill bit for 3″ penetration.
At some point drilling became difficult, then impossible. From the picture, there are no obstructions, a clean wood stud. Drilled in the area of where the red & green lines meet on single stud. Put the phillips screw on a battery impact driver and was difficult, then impossible. Got about 1-1/2″ penetration and felt like hitting a rock or steel. The impact driver couldn’t even reverse the screw. Unscrewed it with some RoboGrips. See pic for how bent screw is.
The only thing I can think of is hitting the knot right below where the red & green meet. But would a knot stop a drill bit and an impact driver? What other possibilities are there?
On the other mounting point, I’m a bit too close for comfort on the electrical wire going through the double-stud. Any way to detect the wire? My little red-light, beep tester isn’t sensitive enough to go that deep. Otherwise, I’ll have to raise bar higher than desired. Thanks in advance for any help.
