What is the best way to make a circular cut in ceramic tile?

Question

i need to make a 4 inch round hole to fit a toilet. I purchased a "ceramic tile cutting" kit from Lowes, but it was a joke. Couldn't make a dent in the tile without completely wearing down. I have a wet saw but this is not practical for a round cut.

Answer 1

I agree with DIY Doc, but if you do need to just use a 1/4 " masonry bit and drill out the circle.  I've used my wet saw to cut a circle, you rotate the bottom of the tile under the blade,

and grind out a circular U shape until you get thru the top.

Answer 2

No offense, but I tile EVERY day of my life and your issue is unnecessary.

   I've also remodeled a bunch of bathrooms, and yes I always pull the toilet for flooring, but never snug around the vent with tile. It serves no valid purpose to do so. IF the tile (as it should be) is installed, and within the perimeter of the toilet base, that's all you need to do. Obviously it may not be full sheets under, but the idea is to give the illusion that they extend fully.

   Certainly there are Diamond bit tools and stated resolutions will be expressed here, but for my time, and trouble, I've never had an issue or a negative call back.

   Your only issue should be NOT resetting the toilet too soon, and use a Wax ring with a rubber flange extension, embedded.

They make a hole saw for ceramic tile.  You might have to try a specialty store.  It's should be the same as you would use for concrete.
