How can I cut off 1/8 inch from ceramic tile?
The best approach is a tile saw that can make small precise cuts along the length of a tile. It is a power tool like a table saw but uses a diamond impregnated blade and a water cooling system. They can be bought or rented.


A cruder approach if the tiles are not too big (4x4 should not be a problem)and there are not too many tiles to cut is a tile nipper.


These chip off little bits and you can work along an edge to do the whole side. However, some tiles are especially brittle and some are prone to cracking. I would not try it unless you have some spares to test on and in case the selected ones break.

And, as noted in Jimmy James' comment, eye protection (e.g. safety goggles) is a must for nippers and also for the saw. A random bit of ceramic shard or grit shot into the eye is no joke.
