Learn how to cut tile with this DIY video tutorial.
If you need to make angular and circular cuts, use an angle grinder and fit a diamond disk. You'll need to fit a continuous diamond disk, not a segmented one, because a segmented disk will chip the tiles. And if you're using an angle grinder, don't forget your personal protection equipment, ear muffs, dust mask, and eye protection.
