Do I really need to remove stick-on floor tiles before putting underlayment

Hello everyone,



I was advised to remove the floor tiles in my bathroom before putting my 1/2 of plywood before ceramic. The floor tiles are kinda like linoleum but thicker. I could easily drop the plywood and screw right threw them.



I am not lazy or anything, but if I can avoid having to remove them, I will.



Your advice will be much appreciated.



Thanks!

Nic
