You may use ceramic tiles outdoors, but they are not the best option. They are best suited for indoor use, which is where they are typically used. This is because they can have a high water absorption rate and are classed only as providing “good” water resistance. They are also relatively soft compared to porcelain and will likely chip and crack with outdoor use. They have a MOHS hardness rating of 6 or 6 and a PEI rating between 3 and 4.
Porcelain tiles are the preferred option for use outdoors. Unlike ceramic tiles, they have a very low water absorption rating of 0.5% and are classed as providing “excellent” water resistance. They are also much harder than ceramic tiles. They have a MOHS hardness rating between 7 and 9 and a PEI rating between 3 and 5.
