I have a new mirror that I want to put up in bathroom. When the bathroom was fitted, they put all the towel rails etc up, in the grout lines and not through the tiles. Seems to work OK.
I have found some useful videos about how to drill through tiles safely. http://www.guardian.co.uk/lifeandstyle/video/2010/oct/05/diy-drilling-tiles.
Worried that screws could work loose from grout (it is a heavy mirror) but reluctant to have too many holes in tiles
Question is, what are the pros and cons of drilling into tile or grout?
Advice appreciated guys
