You can do it yourself if you have the necessary tools and some patience, but removing bathroom tiles can be a tough operation. The following is a list of actions that can be followed in order to remove tiles from the bathroom:

Collect all of your equipment. To successfully remove the tiles from the bathroom, you will want a few different instruments, such as a hammer, a chisel, and a pry bar. As an added layer of defence against flying debris and jagged edges, you should probably put on some gloves and safety glasses as well.

Make indentations in the grout lines. To remove the tiles from their substrate, score the grout lines around the tiles with a chisel and hammer. Take your time and be careful so that you don't end up hurting the tiles or the substrate around you.

Get rid of the tiling. After the grout lines have been scored, carefully peel the tiles away from the substrate using a flat-bladed pry bar. To prevent the tiles from being broken, be sure to move slowly and carefully while you work.

Remove the adhesive. After the tiles have been removed, it is possible that any glue that is still on the substrate will need to be removed. Make light strokes with a putty knife or scraper to carefully remove the adhesive.

Scrub the area thoroughly. When you have finished removing the tiles and the glue, scrub the area well to get rid of any debris or dust.

By carrying out these procedures, you will be able to take out the tiles in the bathroom and get the area ready for new tiles or another finish.
