GRAB BAR INSTALLATION - How to avoid cracking tile

Grab Bar installation can be a little frightening for some, even those with much experience in the building trades. One of the main concerns can be tile damage during the grab bar installation process. This can of course occur but can be avoided by paying close attention to the task at hand and thinking things through.

It is rarely the drilling process that will directly damage the tile, but actually the process of fastening the grab bars. Here are some common factors which immediately come to mind.

1. Overtightening - I am alway careful to adjust the torque on my drill-driver to be sure I do not overtighten. I frequently finish off each screw by hand to be certain of this.

2. Assessment of hole depth available - it is essential to be aware of the clearance available behind the hole that you have drilled to be sure there is ample room for your fastener. If your fastener cannot go any further and a tile anchor is in use, the anchor will create a backward force on the tile and possibly crack the tile. Whenever I attach grab bars to outside walls or walls consisting of tile, drywall (or backer board), furring then block - I drill into the block to make sure the screws have ample room available.

3. Assessment of tile condition - It is important to inspect the tile prior to installation for any signs of pre-existing damage, loose tiles etc. by looking, listening and feeling the surface you plan to work on.
