cutting 1 1/4 inch holes in ceramic wall tile for a shower faucet
I need to cut holes in the shower wall for my plumber to install a 3 stem faucet with diverter. The installation instructions from California faucet says that each hole needs to be 1 1/4 inch in diameter.
First question, why so big, when the stems are skinny? Is it because you need to allow for future access to the cartridges?
Second question, how would you go about cutting the holes in the wall? A large bit (hole saw), or a 1 1/4" circle of tiny holes.
I appreciate any advice or experience.
