After removing the grout use a small pry bar or a similar tool to pry the tiles away from the wall. Once those tiles loosen pry them off. Use a chisel to scrape away the dried thin set carefully chipping it loose from the tile without scratching it or harming the tile itself. Use the scraper to clean off large debris and then clean off any soapy residue with a damp cloth.

Use a ball peen or masonry hammer and cold chisel to tap the pieces free. Start removing mortar from tile with the tiles free from the wall or floor you can now start cleaning them so can reuse the tile. Be careful not to exert too much pressure downward on the tile or you could cause it to crack. Removing tile from older style mortar walls can be very challenging.

In some cases the only way to tear out the ceramic tile is with heavy equipment such as a jackhammer or air chisel.

A wide blade putty knife is helpful in prying the tiles loose. Tiles installed with thinset or another tile adhesive often require more work to remove them.
