I’ve just received another question in the comments section asking how to cut larger holes in tile. Holes for things like the controls in the shower, shower lights, toilet flanges, etc.
My normal smart ass answer is: Mark the circle and remove everything that is not a tile with a hole in it.
The short answer is with a grinder and a diamond wheel.
The slightly longer answer is to draw your circle, take the grinder and plunge it into the tile,, straight down, inside the markings of the circle. Continue this around the entire circle until the large piece is out. Then go back around the circle at about a 45 degree angle and take out the rest of the circle just around the markings.
See, difficult to visualize, isn’t it? (I understood it perfectly well…)
