Finding the right tile for your shower doesn't just mean looking at the color and design. You need to also look at the material of the tile. You want a tile that is not going to grow mold or mildew, or damage the grout after a few years of use. Consider shower tiles that are high quality like, porcelain or ceramic. If you have a small budget you can opt for something like ceramic. However, these aren't going to last as long and you might find you need to replace your shower tiles a few more times than you would have to if you bought high quality shower tiles.
