What is the best way to remove wall tiles from the bathroom?
I am assuming you are removing them all and are planning to throw them away. Cover the floor and fixtures. Get some goggles and strong gloves to protect you from shards. Get a steel punch like a marking punch or a star drill or a cold chisel. Bash a tile in the center and then use a chisel or steel spatula to remove the parts that did not fall off. Then proceed to an adjacent one until you have a line of them off. Now see if you can loosen the next row of tiles with a steel chisel or spatula along the top edge. If not go back to bashing. Be careful near the floor and fixtures so you don’t break anything you want to keep When they are all off the wall you will probably need to chisel any remaining adhesive, grout, or cement off the wall to get a smooth surface. You might need to patch the backer board if it is nicked.
