Choosing tile for your shower isn’t as straight-forward as you might think. Some considerations are slip-resistance, the shape of the shower (curved versus straight lines), and even the mineral content of your water.

If you prefer a large-scale tile, look for one with a good slip-resistance rating — an A or a B rating is preferable. Bear in mind, too, that if you’re using glass or a sheet-type mosaic tile, it’s up to the manufacturer or retailer to let you know if the tile is acceptable for submersion.
