The grout cleaning and maintenance problem disappears with solid-surface materials. You will be trading off grout cleaning for a surface that is less durable than tile. Marble, granite and stone tile Marble, granite and stone tiles are for those who would prefer them in slab form. The neat thing about these tiles is that the grout line can be extremely thin. This reduces the need for extensive grout cleaning, but does not completely eliminate the chore.
Most marble is susceptible to damage from citric acid and alcohol.
The same is true for many polished stone surfaces. Marble and granite tiles are about the same price as the solid-surface products. Concrete countertops are expensive, require a sealant and must be treated with care. Prices for concrete tops are all over the board. Expect to pay through the nose.
