Need to cut thru ceramic tile in utility rooom? any advice
JB has it right, but just be sure there is no in floor heating, electric or hot water.
Cut your pattern , ocatgon will work nicely, a bit oversize say 1/2" to allow seating of your pipe. Put a wide pry bar under the edge and the tile will pop. You may have to make an x under the tile layer as you proceed down.
