I'm going to drill a couple of holes in a tiled wall in my bathroom. Is it best to drill through the seams or the tiles? Should I avoid vertical or horizontal seams, or does it really not matter?
The holes are for a shower riser (i.e. just a couple of screws with plastic wall plugs/dowels). These look like the plain old ceramic tiles, and they have cracked where they were drilled through by whoever installed the shower.
P.S. I'm aware of the possibility of drilling through a water pipe; will take the necessary precautions.

I would buy a set of glass bits. I linked to some cheap ones - no idea if they are great or not but probably doesn't matter.
It also doesn't matter if you do it on grout or tile - you need to anchor either way.
The key is to start with your smallest bit and work your way up to the hole size you need. The tile breaks because of pressure. By slowly increasing the hole size you are putting less force on it.
