Glad you asked. Attaching fixtures to tiled surfaces can be a bit tricky if you don't know what you're doing. If a tenant rings up and complains that the towel rail or the toilet roll holder has fallen off, don't call for the handyman just yet. Save yourself some dough and learn...
It's been a little while but l've just knocked up a quick little video showing a cool little trick l use when drilling a tile. It might save you some time and money. Check it out.
