How can I fix the tiles around my bathroom faucet?

You will need to remove any loose tiles. Replace and repair the water damaged wall. Then apply the tiles.

If your whole shower is like the picture and the backer board behind the tiles are as wet as what is being shown in your picture, you have a project ahead of you. You will first have to shut off the water coming into the shower. Then you will remove the fixtures. Remove the tile and grout. I would wear a safety mask just in case there is black mold behind the tiles. Check your backer board it needs to be replace in the pic you are sharing and it very well may need replacing all around. If you do need to replace all the board let the shower air out and dry and I would spray the area with a bleach solution. If you find a lot of black mold you may have to bring in an expert. Once all that is done put up your new beautiful tile or fiberglass surround and grout or caulk if you decide to get fiberglass. Good luck.

If you can find matching tiles great. Take out the damaged part and replace with new tiles. Or get a contrasting tile and fill it in.

Take down damaged tiles. Fix the water damage or you will be doing this again.

Go to Floor and Decor and get the same size tiles. I do not know if they will have that color but you can coordinate. You will need grout and Thin-set mortar a common bonding agent used to attach tiles to the backer board or concrete subfloor. It is made of cement and fine sand and will need to be mixed with water if bought dry.

Hi Melissa, it's sad but you will need to remove all those tiles and fix the issue then replace them. hope this helps.
