To the contrary that happen with slabs, tiles are usually no more than 12 inches (30cm) by 12 inches (30 cm). Manufacturers cut these tiles slightly thinner than slabs, which makes them easier to treat and ship. The polishes used on tiles are the same, but their lighter weight may allow them to be placed on normal counters as they are. Slabs usually require extra support. .
